1. Chain Sizes

Pitch is the distance from one link to another. Pitch matters the most. The pitch, in eighths of an inch, is the first digit of the motorcycle chain size.

Roller Width (Wr) is the distance between the insides of the chain inner plates.

Named width is the minimum width of chain, and the maximum width of sprocket. The named width, in eighths of an inch, is the second and third digit in the motorcycle chain size.

Roller Diameter (Dr) is the third thing that matters for fitting a given sprocket.

Any replacement chain must have the same pitch and roller diameter (Dr). The roller width (Wr) should be the same but can be a little more. The roller width is correct for the sprocket width when the chain can move side-to-side on the sprocket, but only a little bit. So the sprocket width needs to be a little less than the roller width.

Chain replacement: When there is nothing else close to the chain except the sprocket teeth, the three blue dimensions, pitch, width, and roller diameter are all that matter for replacing an entire chain (and the number of links). These are related to the places that touch the sprocket. If the 3 blue items on the replacement chain are the same, it will fit the same sprockets.

The exceptions are when there are other things close to the chain. On some Chinese bicycle engines with a 415 chain, the engine case is very close to the chain. A 415H replacement chain is wider, scrapes the side of the engine causing damage and breakage. On vintage Motobecane mopeds there are rubber bands on the front sprocket that interfere with a 415H, preventing it from sitting all the way into the valleys. When those are in place a 415H does not mesh well. It sounds and feels terrible. Once the rubber bands are removed a 415H replaces a 415 perfectly. See Chain Service below.

Link replacement: For replacing a master link or one or more individual links, more things matter: inner width, pin length and pin diameter. On modern chains these 3 red items are standardized. But for vintage 1970’s and 80’s chains they were not. Often several different chains interchange (fit the same sprocket), but have different pin diameters, pin lengths, and plate thicknesses. So while the entire chain interchanges, the individual links do not. For example, a vintage Puch master link would not fit a vintage Garelli chain (because the pin is too thick). But an entire Puch chain would replace an entire Garelli chain.

Measuring: Chains for mopeds, motorized bicycles, gas or electric scooters, mini-ATVs, go-karts, mini-cars, and mini-bikes are not on most application charts. For these oddball vehicles you have to determine the chain size by measurement with a digital calipers, and counting how many link pins.

Metric and Inch Some Chinese made scooters and pocket bikes have 04B chains (6 mm pitch) instead of 25 (6.35 = 1/4″). Some have T8F or 05B chains (8 mm pitch) instead of 35 (9.53 = 3/8″). Metric chains look the same but don’t interchange with inch chains.

H versions: The H (heavy duty) versions fit the same sprocket but have thicker wider plates and thicker longer pins. So a 415 master link won’t fit a 415H chain (because the pins are too short), and a 415H master link won’t fit a 415 chain (because the pins are too thick).

At left is Myrons Mopeds master link cabinet, full of master links and half links from 20 other moped shops that closed in the late 1980’s in Southern California. Each of the drawers contains about 10 to 100 links. Each link was measured carefully and/or put through this gauntlet of Go/NoGo gauges, which are the actual master links and corresponding inner links contained in each drawer. From left to right, the order is smallest pitch first, smallest pin first (for that pitch), and the smallest inner width first (for that pitch and pin). Inner width for a master link is the space between the inside of the outer plates, which is slightly greater than the inner width for the chain, as in the chart below.

Notice that there are no “international” master links, like 04B (6mm) or 05B (8mm). These chains did not appear in California until the late 1990’s with the stand-up scooters, pocket bikes, and electric bikes and scooters, mostly from China.

How to install and remove master links.

Motobecane: 1970’s-1980’s Motobecane Mobylette 40, 50, or 50V mopeds, the front sprocket behind the large pulley has some rubber rings that interfere with modern 415H chains. Fortunately the two 1 1/4 inch rubber rings, one on each side of the sprocket, can be removed with something like a curved dental pick. This issue of a chain not meshing because of (unnecessary) rubber noise dampener rings contacting the outer plates instead of the sprocket contacting the rollers, also occurs on Peugeot, but not as much.

Left, the original IRIS chain, meshes correct.
Right, modern 415H, with taller plates,
rides up too high and does not mesh.

Motobecane front sprockets without rubbers.
Left, the original IRIS still meshes good.
Right, the 415H meshes good now.
The end roller is cut away to see the fit.

Peugeot 103: Sometimes the newer “H” rated chains do not fit until after the bike is rode for a few minutes. The two rubber rings on either side of the original sprocket interfere with the larger outer plates on the 415H chain, causing the chain to run higher and not mesh well. After riding awhile the chain noise gets less, as the rubbers get squished and interfere less. Still, it is better to remove the pulley, and remove the rubber rings, shown at right, to have a smooth running chain.

Peugeot 102 front sprocket with rubber rings removed.

Peugeot 102/103 front sprocket with rubber rings removed. 415H wraps around fully.

Peugeot 102: This is the only US-model moped that uses a 42 chain, same sprocket as a 415 (1/2 x 3/16), but lighter duty (thinner pins, thinner and smaller plates). Sedis made both 415 chain for Peugeot 103, and 42 chain for the lighter weight Peugeot 102. Old Sedis chains are often cracked. Then they break/throw the chain. No fun. To use a modern 415H chain, the two rubber rings on either side of the sprocket must be removed, or it won’t mesh properly. See photos at right.

Motorized Bicycles: 415 – Only Kind: Certain modern motorized bicycle gas engine kits use a 415 chain that passes very close to the engine case on both sides. These do not have enough room for the wider-on-the-outside 415H. They require a 415.

Motorized Bicycles: 415 and 410 Mixed: Certain modern motorized bicycle gas engine kits have a wide engine sprocket for 3/16 and a thin rear sprocket for a 1/8 chain. A 415 or 415H chain works but would be expected to have less retention (it would come off easier).

Motorized Bicycles: Long Chain Runs: Motorized bicycles with long chain runs need chain guides and/or chain tensioners, or else the chain comes off when it slaps going over bumps, or when the frame or wheel flexes, or when the engine mounts shift/slip. The kits don’t usually come with any.

American Made Minibikes: There were many different manufacturers of minibikes back in the 60’s and 70’s but most of them used either a 35, 40, 0r 41 chain. Number 35 was used on most all 4-5-6 inch wheel minibikes while 41 was used on larger minicycles such as Rupp Roadster II and Speedway. Number 41 chain will not run on a number 40 sprocket. Number 40 chain will run on a number 41 sprocket but it will be wider than needed.

Fun Karts and Minibikes: Many chains have the chain size stamped directly on the chain links. #35, 40, 41 and 420 chain are used in the Fun Kart and Mini Bike industry. An 11 or 12 tooth clutch sprocket usually indicates the use of #35 chain. 10 tooth clutch sprockets usually indicate the use of #40, 41 or 420 chain.

Why all of this madness about chains? All through the 1970’s and 1980’s when you needed a master link for your moped, you had to get it from a dealer that sold that kind, or else you had to bring in your chain and hope they could find one that fit. If you had a Motobecane and you needed a master link, you could not get one from a Puch dealer, even if you showed them your chain. Their master links had thicker pins. For decades, owners have been frustrated when they bought a #415 master link for their chain, and it did not fit. That’s because there are 18 or so different 415-compatible chains. By the 1990’s no moped shop sold master links, instead they made you buy a whole chain. Thankfully, there is much better standardization in this century, in moped chains. But there are still a lot of older moped chains and substitutes that are all different. So it’s still not possible to tell (guess) what master link a customers moped needs over the phone. Some things never change…

5. Myrons Chain List

Scan up and down the chart looking for similarities. Notice how the pitch P, and roller width W, and roller diameter D, can be the same for many different chains. Too bad the pin diameter A can vary with the maker. Ouch. A pin too big won’t fit. A pin too small will fit, but will be loose. The only way to get the correct master link is by knowing the pitch P, roller width W, roller diameter D, inner width W+2*T, and pin diameter A.

6. Moped Chain History

Vintage Moped Chains: Vintage bikes often have obsolete chains, or they specify the size in an obsolete way. Vintage equipment used the inch size, pitch x width. Modern motorcycles all use chain model numbers, like 428, 520, 630. The above chart shows that connection. In mopeds, there are 18 different chains, all size 415, or 1/2 x 3/16. They have different pin diameters and inner widths. In modern mopeds there are about 3 or 4.

Moped Chain History: When a shop installs a new chain, they throw the leftover pieces in a box. As the years go by, layers of chains accumulate, with the oldest ones at the bottom, as long as no one mixes up the pile. That’s one way to “date” chains. At Myrons, certain boxes of parts have been untouched since about 1985 to 1995. Only one little scrap of modern 415H chain was in that material, from those years. Not even 415H master links were in that time zone. This little scrap is what Shaun believes to be the earliest example of a 415H chain. Shown below on the Motobecane sprockets, it’s gold and says “Taiwan”. Taiwan bicycle products and machinery blossomed in the 1980’s. China made components came out about 15 years later.

Italian Chain History: At least five different Regina chains are original on 1970’s and 80’s Italian made mopeds, two that say “Regina Extra” and three that say “Regina” underlined. See their pictures above. They all have different master links! Craziness!

4.14 x 8.9 1.9 Regina (underline) 6a. tom1 (4.14 x 9.4-9.6)

Tomos Chain History: At least seven different Tomos chains have been used over the years.

Italy 1970’s 3.89 x 8.4

Germany late 1970’s 4.05 x 7.9

Germany 1980’s 4.14 x 9.4

ČZ chain Slovenia? late 1990’s 4.14 x 9.6

CIC 415H Taiwan? mid 2000’s 3.93 x 8.5

415H China? late 2000’s 3.93 x 8.5

Germany 2013-on 4.14 x 9.6

Above, seven Tomos chains take three different master links. The pins range from 3.89 to 4.14mm thick. The inner width ranges from 7.9 to 9.6mm. “Inner width” means measured between the inside walls of the outer plates. A wider inner link will not fit inside a narrow outer link.

First the “Regina underlined” (3.89 x 8.4) on early A3, and Wippermann (4.05 x 7.9) also on early A3, then Wippermann (4.14 x 9.4) on late A3, then ČZ (4.14 x 9.6) on A35, then CIC 415H on late A35, and now plain 415H (3.93 x 8.5) on A55 models. The chains got thicker and wider and taller on the outside, as the decades progressed. The pins got thicker, and then thinner, and now thick again: 3.89 ->4.05 -> 4.14 -> 4.14 -> 3.93 ->3.93 ->4.14. Same thing with inner width: 8.4 -> 7.9 -> 9.4 -> 9.6 -> 8.5 ->8.5 ->9.6. Perhaps this is why Tomos stopped selling master links…

Four kinds of moped pedal threads

Pedal threads: Most bicycle pedals have either 1/2-20 or 9/16-20 threads. But some vintage bicycles use “French thread” pedals, which is metric 14 – 1.25. The 14.0 mm thread is slightly smaller than 9/16″ (14.3 mm), but bigger than 1/2″ (12.7mm).

14mm pedals screw into 9/16 cranks all the way but fit loosely. Then later they break off or strip out easier.

9/16 pedals screw into 14mm cranks so tight they stop half way. Then later they break off or strip out easier.

2 P E D A L C R A N K S

Left and Right: With shoes it’s easy to tell if they’re on the wrong feet. But with moped cranks it is not. A left crank and pedal looks and functions the same as a right. So it is possible for a moped to have both left pedals and cranks, or both right, or the right on the left side and the left on the right side. Then when, say the left side pedal is missing, it might actually need a right, or visa versa.

Righty Tighty: This rule says “Viewed from above the bolt head, turning to the right, clockwise, is tightening”. Almost all bolts and nuts obey this rule because they are right hand thread. But left hand threads are opposite. They obey the opposite rule, “Lefty Tighty”.

How to tell: It is sometimes not easy to tell if a pedal or a crank is left or right. Most modern bicycle pedals are stamped L or R. Most modern reproduction cranks are also stamped L or R. Most vintage European right cranks are stamped D (droit, destra, desno, derecho) or R (recht, right). Some vintage European left cranks are not marked, and some are stamped S (sinestra) or G (gauche) or L (levo, left).

Another way to tell is by viewing the threads directly. When a right thread bolt is held with the tail facing up, each thread slopes upward going from left to right. When a left thread bolt is viewed the same way, the threads slope in the opposite direction. With crank threads, right thread goes inward clockwise, left thread goes outward clockwise. You have to follow the first thread around in a circle with your eyes.

How not to strip threads: Know which way to turn, and use lubricant. Know how it should feel. Know how tight it should be. And know how to use taps or dies or thread files to “clean up” damaged threads, before they fail completely.

Shown here are the 3-style vintage Italian original pedal cranks on Italian (mostly) mopeds with Morini MO1, MO2, M1 engines. These cranks need to be the 3 style, that “goes outward right away”, because the engine sticks out close to the pedal shaft.

Besides clearing the engine when the crank is horizontal, sometimes this style crank is needed to clear the covers above the engine, when the crank is vertical.

Garelli Gulp requires pedal arms that go outward early, with a high offset. Here is the #502 pedal arm set that fits but the arms are one inch shorter.

These 502 pedal arms have 9.5 mm pin holes, but the holes are 1 mm closer to the pedal shaft, so they need 9.0 pins ground 1 mm thinner on the flat side.

The clutch wheel often scrapes against the left pedal crank. On non-variator (Dimoby) models, like 50 or 40, the engine does not swing back as the bike speeds up (but it does swing to keep the belt tight). On those models there is also 3/8 inch more space between the clutch wheel and the pedal crank. So they “never” scrape.

Puch threads
are intentionally
made weaker

What were they thinking? Pedal cranks for Puch mopeds have about 1/3 of the threads removed by machining. This makes them get stripped easier. The only plausible explanation is Puch was thinking about safety. When a rider forgets where the pedals are, and leans over in a turn, one pedal can hit the ground. If it hits hard enough it can cause a crash. Puch pedals are designed to break away, rather than causing a crash.

Pedal Crank Selection:

Offset: Ideally the pedal arms should have enough offset to not hit anything, even after being bent inward a little, yet not have too much offset. Too much offset causes the pedals to hit the ground sooner when leaned over, and to stick out more when parking or storing, and to hit the riders feet more when backing up.

Length: Longer pedal arms provide more leverage. For mopeds the pedals are mainly used for starting the engine, rather than pedaling. So if the engine turns over easily then long pedal arms are not needed. Longer arms hit the ground sooner when leaned over. And when not pedaling, one foot is more forward and the other is more back. So shorter arms are better, in many ways. But for pedaling, longer arms are better, especially for riders with long legs.

Style: Some engines or bikes need cranks that “go outward right away” because something is sticking out near the pedal shaft. This is the style 3 above. Sachs 505, Morini MO1, MO2 and Garelli VIP engines are some common examples.

Pedal Crank Service:

The bend forms about

Here it is held high up.

VAR pedal arm bender.
This has straightened
500 bent arms, saving
customers $10,000

Straightening: 1. With a special tool like the one shown, and two people, a bent pedal crank can be straightened in one minute without any removal. The second person has to pull on the bike the opposite way, by standing hard on the opposite pedal. 2. Without that tool, the pedal only is removed and a long pipe that fits closely over the crank is used to apply torque. 3. For more stubborn cranks, the crank is removed and placed in a large bench vise. Again the pipe is placed over the crank at the right place, and torque is applied. Moped cranks require 100 to maybe 600 foot-pounds of torque to bend. This is done without heating.

Re-threading a crank

Re-threading: Often just the first few threads become messed up. Bicycle shops have pedal taps, size 9/16-20 Right and Left, that can repair partially-stripped threads on moped cranks. Hardware stores do not have those taps, instead they have 9/16-18, more coarse. So pedal taps are a bicycle-industry-only item.

Repairing pedal crank threads is done by starting the tap from the good side, which is the back. Sometimes crank removal is required, and sometimes it is optional. Cutting fluid, or at least oil, is applied. The tap is moved back and forth as it is screwed in (like 4 steps forward and 3 steps back), until it goes all the way through.

Rethreading a M14-1.25 crank to 9/16-20 (from 14.0 to 14.3mm) is more difficult. The plated steel is hard and tough. It takes longer and requires more force. The crank arm and tap get hot by the end of the 10-20 minute process.

Pin removal

Pedal Crank pins

These round pins have a flat wedge that fits tight against a slot in the shaft. They are pressed or hammered in and out. In the bicycle industry they are known as cotter pins. Here they are called crank pins or wedge pins.

pedal pin 9.5 mm, price $2.50
pedal pin 9.0 mm, price $2.50
special 9.0 x 6.5 $7 each. The flat is 1mm lower.

Right: regular 9mm pin
Left: same but thinner

One Up One Down: This rule says that if one crank pin points up, then the other should point down. This makes the left and right crank arms parallel at 12 o’clock and 6 o’clock. When the pins are both up, the arms are at 12 o’clock and 5 o’clock, lopsided and awkward.

Special pins: The 502 aftermarket pedal arms require special wedge pins. The regular pin shown on the right is 9.0 x 7.2 thick. After grinding it becomes the special pin on the left, which is 9.0 x 6.5 thick, or 1.3 mm thinner. These pins are required for the 502R and 502L aftermarket pedal arms. Price $8 each

Some mopeds with external pedal shafts, and separate pedal and motor chains, have one of the crank arms permanently attached to the shaft and sprocket. With those, to get a new sprocket-side arm you have to replace the shaft-with-arm.

Some mopeds with external pedal shafts, and separate pedal and motor chains, have no crank arms permanently attached to the shaft and sprocket. With those the sprocket-side arm can be replaced.

Some mopeds have one drive chain and some have two. Two-chain mopeds, with both a motor chain and a pedal chain, have freewheels, like most bicycles. The freewheel is the rear pedal sprocket that spins free and goes “click click click” in the reverse direction, but locks up solid in the forward direction. The freewheel allows the pedals to be stationary even when the rear wheel is moving forward. The moped brands with right-side freewheels are Puch, Peugeot, Motobecane, Batavus, Sparta (Foxi), Hercules (Sachs), Piaggio (Vespa), Honda (PA50), Kreidler, KTM (Foxi), Kynast, Flandria. There are two brands with left-side backward freewheels, Jawa and Benelli. All of the other moped brands do not have external freewheels, but instead have a freewheel mechanism inside the engine unit.

The freewheel screws on and tightens with pedaling. Once it is tight, a special tool is required to remove it. The tool fits into slots in the freewheel center. Some low-end modern single-speed bicycle freewheels do not have removal slots. Those cheap kinds can be removed by destroying the freewheel. To remove a freewheel destructively without a removal tool, the freewheel is first disassembled, where all the little balls and clickers fall out, and then the inner hub is unscrewed in a bench vise or with a pipe wrench.

Most freewheels go on the right side of the bike and thus have right-hand thread, but Jawa and Benelli ones go on the left side of the bike and have left-hand thread.

Freewheel threads: Like with pedal threads there is a common size and an uncommon size slightly smaller.

The common size is 1.375″ – 24, which equals 34.92 – 1.06 mm. Most modern bicycles worldwide have this ISO (International Standards Organization) standard freewheel thread type.

The uncommon size is M34.7 – 1.00, which equals 34.70 – 1.00 mm. This “French” thread type is on vintage bicycles from France, Belgium, Spain or Switzerland, and on Motobecane mopeds with Motobecane-made hubs.

So the French freewheels are slightly smaller than the rest of the world, 34.7 instead of 34.9. That small amount does not matter as long as the bike is pedaled gently. But it does matter when the pedals are pushed very hard. Then the loose fitting threads on the wheel hub can strip out, a disaster.

It is difficult to tell which thread type a hub has, by measuring the thread tops with a calipers. The 34.92 thread hubs measure 34.65 to 34.7. The 34.70 hubs measure 34.55 to 34.6. On some hubs the tops of the threads are worn down and measure less. So a standard thread might seem like a French thread type. Because of this, it is better to put away the calipers and use “feel”.

When the freewheel and hub have the same thread type, the freewheel screws on easy, yet has no looseness. Looseness is felt with fingertips pulling and pushing the freewheel center side to side. When a 34.92 freewheel is on a 34.7 hub, the center of the freewheel can move 0.22 mm. Here is a video of that. That looseness or “wiggle” is felt. The same is true for any threaded thing. When a bolt fits a nut, it screws on easy and yet does not wiggle.

All of the freewheels in Myrons Mopeds inventory were measured by feel. For each bike model listed above, a sample rear wheel with original freewheel was measured directly by feel. The freewheel was removed. It’s threads were checked by screwing onto both a French and a standard hub. The wheel threads were checked by screwing on both a French and a standard freewheel.

Gauntlet of test wheels: MB 40, Batavus M48, Peugeot 103, Model 7 hub, MB 50, MB 50, MB 50VLA.
Not shown, Puch wheels and hubs, Sparta, Peugeot 102 hub, Kreidler, Sachs, KTM, Kynast, others.

Result: None of the hubs or freewheels had French thread, except Motobecanes with Motobecane-made hubs. Wow!

Result: All Leleu-made hubs have standard freewheel thread 1.375″-24, even those for Motobecane. All Motobecane-made hubs have French thread M34.7-1.0. All Motobecane-made “6-star” mag wheels have standard thread, but it is tapered and begins with French thread, so that either type of freewheel can be used.

How to tell: The best way to tell if a 1970’s Motobecane moped rear hub is Motobecane-made (and therefore French thread) is visually. There is an prominent M logo on the freewheel side. There is no step on the freewheel side, instead it slopes gradually. The flanges go farther out from the spoke holes. So from 100 feet away, viewed from the side, the Motobecane-made hubs appear larger than Leleu-made hubs.

Summary

All two-chain rear hubs or wheels, on mopeds from the 1970’s and 80’s, have standard freewheel threads, except Motobecane-made hubs on 1950’s -60’s and some 1970’s Motobecane mopeds.

A standard thread freewheel fits a French thread hub and works fine when pedaled normally. Only when a strong athletic person pedals very hard, the hub threads can strip off, requiring wheel or hub replacement.

Motobecane 100mm hubs
are also French thread

1950’s – 60’s Motobecane: Many models, maybe all, had French freewheel threads M34.7-1.0. In the 1960’s the parts manuals specified the thread. One example, shown at right, is for Motobecane AV88 and Motoconfort AU88. It lists the 18-tooth 15244 freewheel as having M34.7-100 thread.

The French freewheel thread cover up: It is very odd that, after 1976-77, Motobecane had two different freewheel threads, but they hid that fact. Instead they made the teeth different, 15244 (French thread) was 18 teeth, and the newer 14298 (standard thread) was 20 teeth. The Motobecane America parts manuals list both freewheels without explanation. There does not seem to be anything about freewheels in the Parts or Service Bulletins. The physical freewheels do not say the thread. The actual parts labels do not say the thread either. As a result, this cover-up has caused confusion and mystery for 39 years (1978-2017).

6. Length Calculation
7. Calculated Lengths

1. Spoke Length

Length can vary by 1 or 2 mm depending on the definition.
Spokes from the bicycle industry use Inner Edge Length.
Spokes from the moped industry use Center Line Length.
Spokes measured directly usually use Total Length.

Here we use Center Line Length. So a spoke that we say is 144 mm long, is 143 mm long from a bicycle spoke supplier, or 145 mm long from simple measurement.

2. Quick Info

Replacement spokes can be up to 2 mm longer or shorter, as long as the original spoke was not already long or short.

Inner or Outer: Spokes can go inside the hub flange or outside. On original moped wheels they alternate inner and outer. Inner spokes are longer because they have less than 90° bend. Outer spokes are shorter because they have more than 90° bend. Here we use the 90 degree equivalent for the named length. See illustration.

Spoke thickness goes by several wire gauge families. Scroll down to Spoke Threads and Gauges for details.

Spoke threads: Most spokes have rolled threads, where the thread tops are raised higher than the spoke. Some spokes have cut threads, where the thread tops are lower than the spoke.

Thread pitch: Here the meaning of “thread” is the width of one thread, in mm. So ten 0.60 threads is 6 mm length.

ID Marks: For each spoke thickness (gauge) there can be several thread pitches. For many that means the ID mark on the spoke must match the ID mark on the nipple. ID marks include (A) (R) Italy, ( ) UK/Asia, (∴) USA, (Б) Swiss, (♣) (U) Germany, (C) (B) (*) (+) or (Я) France. Scroll down to Spoke Threads and Gauges for details.

Definition of size

Size: The size of a drum brake shoe is not it’s actual length and width. The size is the width, and the diameter of the imaginary circle which the arc is a part of, which is also the brake drum diameter. Notice that the actual length is a little less than the drum diameter. So a 90 x 20 mm brake shoe is actually about 84 mm long by 20 mm wide.

Brakes that have the same drum diameter and width, can still be different, because of these things: the pivot post can have different positions, thicknesses and widths, the spreader shaft can have different positions, thicknesses and widths, the spring holes can have different positions and widths. So the size is actually several numbers, not just two.

Note 1. EBC322 requires grinding. Without grinding the spring rubs and makes noise. The depth is made just deep enough so that the coils of the spring never touch the brake shoes. In the photo, right is before grinding, left is after.

Note 2. All pre-1978 and some 1978-80 Motobecanes have Motobecane brakes, MB# 21730 (EBC876). There is a left and a right shoe. Most Motobecanes have these brake shoes, but some 1978-80 have Leleu brakes, MB# 16104 (EBC322). On those both shoes are the same, like most other drum brakes.

Note 3. EBC322m is made from a EBC322 by 1. slight grinding of the sides at the spreader end, 2. dremmeling on the inner side of the spreader spring hooks to make the spring stay farther away from the spreader cam, 3. reusing the original MB springs because they are thinner.

Note 4. The Grimeca 90×18 brake shoe has the most moped applications. It is on almost all Italian moped and mini-bike spoke wheels. It is also on German (Hercules), Austrian (KTM), Yugoslavian (Tomos), Mexican (Carabela), and American (AMF) moped spoke wheels. The Italian made Grimeca 90×18 brake shoe is second only to the French made Leleu 80×18 brake shoe in total number of units.

Note 5. Grimeca-U brake shoes are the same as Grimeca except for the spring. The red places in the photo are what is different. Grinding and drilling are necessary to convert Grimeca type shoes to Grimeca-U type.

Note 6. There is no visible difference on the outside, between a V-spring brake plate and non-V-spring (U-spring or dual coil) brake plate, but inside there are three differences. 1) the cam shaft on a V-spring type has a retaining plate, while a coil spring type has no plate (to allow installation by “folding the taco into a tortilla”). 2) the pivot shaft on a V-spring type is longer and has a rounded groove for the V-spring. 3) the pivot shaft on a V-spring has no center groove for retention, while the coil spring and U-spring types have a center groove (for the center ridge on the shoes). In this photo the left 2 are U-spring and the rest are V-spring.

Note 7. These are the older Jawa spoke wheel brake shoes, with 5.0 mm thick lining instead of 2.5mm. That makes the diameter increase from 85 to 90mm, to fit “Italian standard 90mm” moped wheels.

Note 8. These are EBC613 brakes with the pivot post half-hole widened from 8mm to 9mm, for the bigger Indian post, and with thinner Indian coil springs.

Note 9. The 090203 modern aftermarket EBC613 spring holes do not have enough material and strength for a U-spring. The older Indian brake shoes have much more material around the spring holes. So EBC613 cannot safely be drilled out to accept a U-spring. That’s why 090204 replacements are unavailable.

090203 brake shoe set with coil springs and a 090204 U-spring.

Note 10. Many Indian mopeds with beautiful Taiwan-made Mira snowflake mags need these brake shoes, because the originals deteriorate and/or de-laminate. These EBC brakes look different, with different ribs than original, but they are an exact replacement.

Note 11. EBC601 is the same as EBC615, except the lining is wider. Grind off 2.5 mm from each side to make a 615 from a 601.

Note 12. Derbi brake plates can have two different cam thicknesses. Older models 1977-78 mostly had 10mm thick cams and 105251 brake shoes. Later models from about 1979-on had 8mm thick cams and 105252 brake shoes. See photo. 105252 shoes have steel plates on the cam end, but 105251 do not. To make 105252 shoes fit on an early 10mm cam either the steel plates must be removed from the brake shoes, or the 10mm cam ground thinner to 8mm.

Note 13. Derbi 105252 brake shoes (for 8mm cam) are made in two versions that interchange. Derbi-105-open type shoes have half-circle pivot ends, while Derbi-105-hole shoes have full circle pivot ends.

Brake Shoes Info

Types: There are four types of drum brake shoes used on mopeds:

1. Open type with coil springs: When the center of the wheel is small enough, the open type with coil springs is preferred because servicing is easier. To install, connect the springs and place the shoes in the shape of a taco. Then fold the taco into a flat tortilla. That stretches the springs without any tools. Then tap the shoes with the handle of a screwdriver until they snap into place. The advantage of this style is easy servicing.

2. Hole type with coil springs: These brake shoes have a large hole in the pivot post end, and two small coil spring holes. They cannot be installed by “folding the taco into a tortilla”. But they also cannot separate from the pivot post. The advantage is slightly more safety.

When the center of the wheel is big and the brake drum is small, the U spring or V spring type is required. Otherwise the coil springs rub on the wheel center and make a violin sound.

3. Open type with U spring: The U spring goes inside the pivot post. The brake shoes and brake plate are the same as the hole type with coil springs. Only the spring is different, a single large U-spring instead of two small coils. For Grimeca 90 x 18, minor modifications to the coil spring brake shoes are required to fit a U-spring. See below. The advantage of this type is greater spring clearance and compatibility with type 1.

4. Hole type with V spring: The V spring goes outside the pivot post. These brake shoes have a large hole on the pivot end (not the smaller spring holes), and the V spring goes around the pivot post. So the pivot post has a rounded groove for the spring. The advantage of this type is slightly more reliability and safety.

But installing the spring is difficult and requires a special spreader tool. At left is that tool. It is made from a M6 x 30 screw, nut, washers, special lip-washer for centering, and a 12mm piston pin. The piston pin end and screw head are ground to fit the spring so it can’t slip off. Price $15

Installing Leleu 70mm replacement brake shoes

The replacements have thinner and weaker spring anchor hooks. They can break off during installation when the spring has to be stretched to go over the hook. To prevent breaking the spring hooks, there are two things on the brake plate that need to be ground. One is the top lip on the pivot post. It needs to be reduced in diameter, but with some lip remaining for retention. The top edge needs to be rounded. That helps to not overstretch the spring. Two is the top lip on the spreader cam. It too needs to be reduced, but with some lip remaining for retention.

Once those areas are ground, the shoes can be installed with just fingers and no tools. Do not use prying tools. Only fingers are needed.

Reflectors

July 14, 2014

updated 2022-01

Identification and Dating: Original reflectors have to comply with safety standards in effect at the time they were made. The compliance markings that are molded into the front plastic give a clue to when and where the vehicle was made. The vehicle is always made after the compliance standard, usually many years later. Original tail lights and head lights also have compliance standards that can be used in identification and dating.

Ink stamps: Some reflectors also have an ink stamp on the back indicating the date that the reflector was made. The date the reflector was made is usually many years after the compliance date.

SAE Society of Automotive Engineers is a USA based standards organization that now is worldwide and called SAE International.

UNECE United Nations Economic Commision for Europe makes worldwide standards for automotive equipment and other things. The UNECE “E” number, with a circle around it, on the reflector indicates compliance for a particular country. E1 is Germany, E2 is France, E3 is Italy, … E11 is England, E12 is Austria and 59 other countries worldwide. See country codes for UN reg. 3

JIS Japan Industry Standards are separate from Europe. East Asian countries like Taiwan, China and Korea use Japan standards. So reflectors made in those countries do not have an “E” number.

Speed nuts: Nuts normally screw on, but speed nuts push on. So they should more properly be called “push-on fasteners”. Once “on” they cannot be removed, except by using a dental pick tool to pry and bend back each of the inner petals.

Self-threading nuts (thread cutting nuts) screw on to plastic posts. They can be removed easily, but should not be tightened as much as a normal nut that size.

Broken posts: It is difficult to remove speed nuts without breaking the plastic post. Because of that, many used reflectors have their posts broken off. When that happens the reflector can be re-used by drilling a hole where the post was and using a small screw and nut, instead of the post and speed nut.

Cushions: All of the major moped brands that have reflectors attached by speed nuts use cushions under the speed nut, except Vespa (Piaggio). The cushions protect the posts from breaking and reduce the damaging or annoying effects of vibration.

Shocks

July 14, 2014

Welcome. Shocks are priced and sold by each unless stated.

Price Range: Dark green price is for used in rough condition. Bright green price is for new condition. Some shocks are available in various used states, ranging from “rough” to “like new”. So the dark green is the lower limit, and the bright green is the upper limit, of the price range. Most will be in between the low and the high, and priced accordingly.

N/A means Not Available.

Damping: Most of these rear shocks do not have hydraulic fluid (oil) damping. Since most are pure springs with no damping, they are very bouncy. Certain high quality ones have some damping, and are less bouncy.

Length: The length is from center of hole to center of hole.

Width: Besides length and eyelet sizes, some shocks are limited in width by the frame or body panels. On Motobecane for example, you can’t put wider shocks even with the same length and eyelets (unless some bodywork is cut off).

Stiffness: You can’t tell how strong a spring is, until you squeeze it. Heavier people need heavier springs, and vice versa.

Travel: Mopeds are for going slow on smooth roads, and so do not need much suspension travel (how far the wheels can move up or down when hitting a big bump). More travel makes the bike taller, but more able to handle bumps. 2 to 4 inches is typical.

Shocks with 8mm Eyelets

<< This Tomos 221032 shock has more travel, more precision, and other features that make it outperform most other moped shocks. It has some damping, more than other moped shocks, but not as much as a true hydraulic shock. It is also adjustable in spring preload (stiffness) for different rider weights. The longer travel makes bumps feel smaller.

1. Ball Bearings

Ball bearing types

Loose the balls can be removed individually (and roll away forever)

1-piece the balls are in a retainer ring than cannot be removed
1-piece the contact is radial in a full-U shape “full contact”
1-piece for carrying pure-radial loads (perpendicular to the axle)

3-piece the balls are in a retainer ring that can be removed
3-piece the contact is angular in a half-U shape, for some side loads
3-piece only Bo15, L17 and E20 are 3-piece “angular contact”

1-piece versions

00 open: has no shields or seals
RS sealed: has a rubber seal on one side
2RS double sealed: has rubber seals on both sides
Z shielded: has a shield on one side
ZZ double shielded: has shields on both sides

The shields or seals are pressed in. They can be removed by poking a small hole with something like a dental pick, and then prying the hole outward.

Roller bearings can carry more weight, but are for low rpm. Thin long rollers are called “needle”.
Ball bearings can take higher rpms and have less friction than rollers.
Rollers can be horizontal (radial loads), angled (radial and side loads), or vertical (side loads).
All of these below have horizontal rollers for pure radial loads.

The benefits of a needle bearing compared to a bushing are 1) ability to operate with low lubrication, 2) less friction and therefore less heat generated, 3) floating needles can fit a small range of diameters, as long as OD minus ID equals twice the roller diameter.

One side has writing and an anti-clockwise arrow. The other side is plain.
Viewed from the writing end, the shaft can only rotate anti-clockwise. Clockwise it locks solid.
Installed in a Tomos clutch drum, the writing side faces out.
When a Tomos piston seizes, this can get damaged, and become locked in both directions.

6. Bushings

Spacers and bushings are metal or plastic tubes, that can have the same appearance. The name depends on what the tube does. A “spacer” carries an axial load, where the length matters the most. A “bushing” carries a radial load, where the diameter matters the most. Bushings are also called “plain bearings”. Spacers are also called “distance bushings”. This source of confusion is similar to that of “mopeds” and “scooters”.

Clacking vs Clattering

Precision Reaming

Most of these require reaming after they are pressed into the rod. The reasons are 1) they have a very tight press fit for their size, so much that the inside diameter becomes smaller after they are pressed in, and 2) some are made slightly larger or smaller than others. Only Puch and Jawa offered pre-reamed piston pin bushings, which can sometimes need light reaming. The reason why not every kind is made pre-reamed, is that pre-reamed or re-used ones do not hold as tight as un-reamed new ones. When they don’t hold tight they can slip easier.

Disaster strikes: Piston bushing slippage causes oil hole blockage. Then the piston pin and bushing do not get any lubrication. Not having oil mixed with the gasoline also causes the piston bushing to not get any lubrication. Without oil, soon the bushing overheats and sticks-melts to the piston pin. That causes the piston pin to rotate back and forth inside the piston, instead of being stationary. After a while the piston pin holes wear out. The loose piston begins to make a clacking sound at idle and a screeching sound at high speed. The compression ratio is reduced by the loose piston. That causes the engine to be less powerful and difficult to start. The incomplete combustion also makes the spark plug black, which worsens the tendency to be difficult or impossible to start.

1. Seals

Seals are for sealing rotating or sliding shafts where they emerge from a sealed compartment. Fork seals and shifter shaft seals are sliding type. Engine seals are rotating type.

This seal inner lip has a circular thin coil spring that holds onto the rotating shaft. Click to enlarge and see the tiny coils of the spring.

Most engine seals are for preventing oil leakage. When four-stroke crank seals leak, the engine still runs the same, but oil drips out. But two-stroke crank seals are also pressure seals, keeping air in (or out). When they leak, gas-oil mist leaks out, and fresh air leaks in. Then the engine won’t idle or accelerate good. That is because two-strokes “breathe” through the crankcase.

Metric seals are specified by their type and size (inner, outer, and thickness, in mm).

Applications and year ranges listed below are for models that sold new in the USA. Many of the year ranges would begin earlier or end later for worldwide models.

Locations:
BS brake switch, CL clutch, ES engage shaft, FO fork,
FP fuel petcock, LC left crank, PS pedal shaft, PU pulley,
RB rear brake, RC right crank, RH rear hub,
RL right and left crank, RP rear pulley, SS sprocket shaft,
TS transmission shaft, UN unknown, VD variator drum
