Jawa Parts

American JawaJawa USAWelcome. Please visit the sister section Jawa Info first, to identify your Jawa model.

Jawa parts before the 1980’s, were all made by suppliers from Eastern European countries, probably mostly from within CSSR (Czecho-Slovak Socialist Republic). Trade with Western Europe was restricted. So instead of sourcing their components from Germany, Italy, France like other moped makers, they had to get things from Eastern Europe or USSR suppliers or make their own. Yet they did export the finished product to the US and many European countries.    

By 1980 Jawa mopeds, US models, had Domino controls with CEV lights and switches, both made in Italy.

1977 Jawa Transistor 40

1977 Jawa Babetta
(US model 207.011)

This parts book had many pages from the earlier Babetta 28 book that were not updated. It was for the 206 and earliest 207 with a rigid frame (no swing arm), because it did not include any of the parts specific to the swing arm models, like the rear shocks. But most of the Jawa mopeds first sold in the US starting in 1976, were the 207 with a swing arm frame. So there was confusion when US moped dealers ordered center stands and got the wrong kind. The misleading parts book explains why there are leftover rigid frame new parts.

Jawa Parts List Model 207.300

Jawa 207.300 Parts List

1979 Jawa X30
(US model 207.300)

This late-207 parts manual, dated 1979, is for 1979-83 American Jawa models. But it does not include any of the parts unique to the top tank models, “Supreme 2” and “Supreme 3”. There must have been a supplement for that, sent to dealers in 1981-82. Myrons Mopeds is missing that sheet, which would have shown the top gas tank (that looks like a Puch Magnum), long seat, and other Supreme-only items.

This late-207 parts manual, from jawamoped.com, is the source of the part names or descriptions. The English words are British rather than American English. It says “tyre”, “mudguard”, “sealing” instead of “tire”, “fender”, “gasket”, for example. Some alternate American English descriptions are added to the right in aqua blue. In some places, to save space, the original British English descriptions are removed, and only the MM-made aqua blue descriptions are shown. This manual is the source of the more complete descriptions with millimeter sizes included on hardware items. It also has both old and new part number for most items.

Jawa 207 piston

Jawa Pistons: Jawa 39mm cylinders, pistons and rings are slightly bigger than others. A Motobecane mid-size “E” cylinder is 38.99, while a Jawa “B” cylinder is 39.02 mm. Jawa pistons have “rounded M” and “circled S” logos stamped on top, the size code “B  Y” (or “1B Y” or “2B Y” etc), and the arrow that points toward the exhaust side. Jawa pistons are classified in the manuals as A, B, or C by tiny (100 microns) size differences. The actual replacements are all “B”. To see the pistons for sale, with prices and more info, click the link in the price column to go to the Pistons section.

Jawa Chain: The Jawa motor chain is not a standard 415 moped chain, although it has the same pitch and width. It has thicker pins, 4.4 instead of 4.1mm. More importantly, it has bigger rollers, 8.4 instead of 7.7mm. Because the Jawa sprockets are made for bigger rollers, they look similar to worn out standard sprockets. The valleys between the teeth are wider and deeper, making the tops of the teeth more pointed. So a 415H moped chain will work OK, but not great, on unworn Jawa sprockets. But if the Jawa sprockets are worn, the chain might skip and jump off.

Jawa Center Stands

Left, Jawa 207 37 150, swing arm type stand, goes outside the frame
Right, Jawa 28-3400, rigid frame centerstand, goes inside the frame

Chains opposite: See below about how the Jawa pedal chain is on the left side of the bike. and so is not like most other mopeds and bicycles. Weird!

Motor chain is special: See above and in the link to Chains, how the Jawa moped chain has bigger rollers than all other mopeds. Weird!

Jawa brake shoes
L, 2.5 lining for Ø85 drums
(on Jawa spoke wheels)
R, 5.0 lining for Ø90 drums
(on aluminum wheels)

Jawa Spokes: Jawa spokes for 16″ rims are all 160mm long (198mm for 19″ rims). There are two kinds, inner and outer. The outer ones go through the hub holes from inside to outside, and have a longer and sharper bent section. The inner ones go through the hub holes from outside to inside, and have a shorter bent section. Each wheel has 18 inner and 18 outer spokes, alternating, for a total of 36. It was an educated guess which part number was for which type. Inners were 07-4016 and outers were 07-4022, at least in this list. Nowhere else is this difference noted. It does not matter much, since either type of spoke will work, with some minor bending during tensioning/truing. 

Jawa Freewheel

Jawa Brakes: Jawa brake shoes are not like any other western European or Asian brake shoe. Most are for a 85mm drum diameter. Some Jawa mopeds with aluminum “mag” wheels have 90mm drums. For those Jawa made the same brake shoes, but with thicker lining, 5mm instead of 2.5. 

Jawa Left Hand Freewheels made by Velo

Jawa LH 18T Freewheels made by Velo, say what year they were made, here 1976, 77, 78.

Jawa Freewheel: The “free wheeling hub” with sprocket, for the pedal chain is on the left side of the bike. All other US mopeds, except Benelli, and virtually every bicycle, with a freewheel, has a pedal chain on the right side. A right side freewheel screws onto a hub and tightens clockwise, as the bike is pedaled. So the hub has a standard right hand thread. But a left side freewheel needs an opposite thread, so it tightens counter-clockwise, as the bike is pedaled. Jawa specifies the freewheel thread in the Model 28 Parts List. It is M35 x 1.0 L.H. (left hand). So Jawa freewheels and rear hubs are special.

Notice how the back side of a Jawa freewheel, lower right, looks like the front side of a conventional freewheel, top left, except for no removal slots. For many years Shaun mistakenly thought Jawa freewheels were conventional right hand thread ones that were missing the removal tool slots. It is not easy to tell the direction of such a fine thread. Tragically some of those special left hand freewheels got thrown away in the 1990’s along with a few Taiwan bicycle ones that were truly missing the removal slots.

Just a reminder, freewheels tighten by pedalling. No tool is needed to install one. But removal requires a special tool, which comes in different styles and sizes. If the bicycle or moped is pedaled hard, then the freewheel will become very tight and difficult to remove.

Jawa Magneto Coils

Jawa Magneto Coils

Jawa 207 magnetos have four source coils (and one pulse coil). Two of them are combined in series to make one. So there are three independent generator outputs, ignition (coil 4b), lighting (coil 7a plus 7b), and horn or brake light (coil 6). The ignition never has anything to do with the lights. The brake light does not make the head light dim at all. So it is like three separate little generators, all in one place. More about Jawa electrical can be found in the Wiring Diagrams gallery. Scroll down to “J” Jawa.

Jawa Ignition Upgrade Kit

Jawa Ignition Upgrade Kit

In 1981 Jawa moped dealers across the US were sent this Service Bulletin #1. It says how to update pre-1978 (model 207.011) ignitions by replacing the old red Tranzimo unit, and the old stator ring with pulse coil, with the newer system, shown at right. The new system had been in use for two years on the 207.111 models, and was proven to be more reliable. Too bad MM does not have any more of those ignition upgrade kits.

Puch 2-speed shift cushions decomposed

Puch 2-speed shift cushions decomposed

All of the polyurethane “pucks” or “shift cushions” on Puch 2-speed automatic engines decompose after 20 or 30 years. If you drive one with decomposed or missing cushions, during the shift it can chatter and shake the bike. This can cause the gears to have broken teeth, a disaster. Every old 2-speed should have new pucks before being rode after years of sitting. They are oil-resistant rubber disks about the size of a quarter.

1913 Pope (Columbia) racer

From the days of true horse power, their bicycle was “an ever saddled horse which eats nothing”. Colombia and Montgomery Ward mopeds are made by Colombia Manufacturing Company, Division of MTD Products Inc, One Cycle Street, Westfield MA 01086

Columbia has been credited with many firsts in the biking industry, since its founding in 1877 by Col. Albert Pope. It has pioneered many improvements to the industry, producing bikes, motorbikes, and furniture for nearly 150 years. Here is the Columbia Manufacturing Inc website, history page. http://www.columbiamfginc.com/columbia_history.html

ColumbiaColumbia Sheet Metal Frame with Sachs engine

 

America’s first moped, is also Shaun’s favorite. Hats off to Columbia! This is a well made, long lasting, economical, safe, and fun bike, very strong and sturdy but not heavy. Definitely one of the Top Ten Mopeds of the 1970’s. Can you dig it?

KKM VIN Info

KKM VIN Info

KKM VIN Info: KKM mopeds were made after 1980, and thus were required to have the 17-digit Vehicle Identification Number and other requirements that the Columbia mopeds did not have.
Digit 1 is the Country, 4 = USA 
Digit 2,3 are the Maker, 33 = KKM Enterprises
Digit 4 is the Line, A = Frame A, B = Frame B (tube or sheet, don’t know which)
Digit 5 is the Type, A = two wheel, B = three wheel
Digit 6 is the Engine Maker, S = Sachs, M = Minarelli, L = Solo, R = Morini 
Digit 7 is Engine Model, 2 = Sachs 505 1D, 1 = Sachs 505 1A 
Digit 8 is Hub Type, C = cast 105mm, B = pressed 105mm, A = pressed 90mm

Digit 9 is check digit 
Digit 10 is Model Year, J = 1988, K = 1989, L = 1990

Based on this and the photo of the red 1988, it’s VIN is 433AAS2CxJxxxxxxx, where x is any.

Then look for it in the Parts by Type menu. Some of the parts category web pages are finished, some are being constructed, and some are still blank. Please email Shaun with a question of a part that you cannot find. 

After days of studying “all” of the Columbia, Mopet and Montgomery Ward parts manuals, service manuals, owners manuals, brochures, photos from the internet, and many actual known parts, this is the result, concentrated and useful information, for you to use. Enjoy!

Notes

Sachs 25 and 30mph exhaust headers

Speed Versions – The only difference between a 25mph Columbia with a Sachs 505/1A engine, and a 30mph one, is the exhaust front pipe or header. The 30mph version is 28mm OD, and the 25mph one is 22mm OD.

Speed Versions – The only difference between a 20mph Columbia with a Sachs 505/1A engine, and a 25mph one, is the rear sprocket. The 25mph sprocket is 42 teeth, and the 20mph is 48 teeth.

#420 Rear Sprocket (on sheet metal frame models) is thicker than most moped sprockets. While most are 4.3mm thick, for #415 or 415H chains, the Columbia (sheet metal frame model) one is 5.5mm thick, for a #420 or 420H chain.

The 42T x 45.5 x 5.5 original sprocket can be replaced with a 42T x 41.5 x 4.3 Italian moped one, but the center hole has to be precisely cut 4mm bigger, on a lathe. Then the chain can be a 415 or 415H, like the front sprocket is.

#415 Rear Sprocket (on tube frame models) has a 115mm center hole, bigger than any other moped sprocket. That is because of the oversize 105mm drum brake that goes inside the sprocket. Having the brake and sprocket on the same side allows the opposite side to have a screw-on freewheel sprocket for a pedal chain.

Columbia Brakes Swapped

Columbia brake shoes swapped

Brakes made in USA by Columbia are compatible with Grimeca brakes made in Italy. The cast aluminum Italian-made Grimeca brake shoes on the early 1976-78 sheet-metal-frame Columbias, directly replace the stamped steel American-made brakes on the monotube-frame and late 1978-80 sheet-frame Columbias. The USA made brake plates, cam shafts, lever arms, are also each interchangable with Grimeca items, but the axles are different 12.0 mm on the American type hub, and 12.7 mm (1/2 inch) on the Italian type Grimeca hub.

Gas Valve (sheet frame) is located on the left front, close to the decompression valve and start cable. The original had the hose spigot on the right, heading toward the carburetor. Although right is prefered, the replacement gas valve can have the hose spigot going down or left. Shown above is a “12×1 spigot down” replacement petcock, on a yellow Columbia.

Columbia Wiring Diagram
 internal ignition ground

Columbia wires close up

Columbia wires
(some disconnected)

Electrical: Columbia lights are completely separate from the ignition. Never will the engine die when the brakes are applied or when the brake light wires are loose, like on many other mopeds. Each of the lights has it’s own generator wire, so they are independent of each other. The 6V 22W AC yellow wire powers the head light, speedo light and horn, the 6V 10W AC green (and green/black) powers the brake light, and the 6V 5W grey wire powers the tail light. Those three lighting source coils, plus a fourth ignition source coil (perhaps 20 volts but not officially rated), comprise the “Bosch 6V 22-5/10” magneto-generator.

Type 236/237 identified by no coolant fill plug

Solo Type 236/237 Engine
No coolant plug above spark plug

Solo Type 254/255 Engine
Coolant plug above spark plug

Solo Engines are made in Germany by SOLO Kleinmotoren GmbH, Postfach 600152, D 71050 Sindelfingen, Germany. Solo made mostly small agricultural motors, chain saws, sprayers, etc. The name is from the revolutionary backpack portable sprayer for pesticides in 1951. The “Solo” could be used by a single person for the first time, whereas in the past pesticide sprayers required a heavy stationary motor pump and several assistants to handle the long hose. See Odyssey, Solo for more.

Notes:

Clutch Seal: The pressure seal for the clutch side on the 254/255 is not just one seal, like normally. It is two seals, the outer one 26x35x7 seals case-to-clutch, and the inner one 15x21x3 seals clutch-to-shaft. This is the Laura clutch seal/bearing design, similar to Batavus. Instead of being separate in it’s own grease, the clutch needle bearing is bathed in the two stroke oil and gasoline. The benefit is it never needs to be greased. The drawback is the crankcase pressure has another place to possibly leak, both fresh air inwards, and fuel/air mist outwards.

How to identify a 1 or 2 speed: There are two types of belt-drive transmissions, 1 speed and 2 speed. The one-speed (ein-gang) “regular” transmission has a solid rear pulley, with no screws around the edge. The two-speed (zwei-gang) transmission has a rear pulley with planetary gears and a second speed auto clutch inside, with 12 screws around the edge. The presence or absence of pulley screws is the best way to tell a 1-speed from a 2-speed, from a few yards away. If the clutch cover is off, the presence or absence of the manual starting clutch lever is another way to tell. 1-speeds have it but 2-speeds do not.

More info about the Odyssey 2-speed: “Home Alone with Mopeds” has an excellent blog about the Odyssey 40/2-2 two-speed belt drive moped. An all original fresh condition bike is photographed and explained, inside and out. Included are pictures of the planetary gears, the second speed auto clutch, and the “secret” switch that allows backing up without turning the engine over backwards.

ColumbiasoloSolo “Colombia” Motor, Type 255

Colombia 2240-2250 clutch

Solo 255 with Colombia “belt clutch”.
The sides of the belt are the friction surface.
No clutch shoes, no friction plate or disk.

How the automatic clutch works: The engine is idling and the belt is stationary. The pulley sides are spinning, but the pulley center is not, because it is on a needle bearing. As the engine begins to rev up, the weights #6 fly out from centrifugal force. They force the outer pulley half #8 inward, causing the sides of the belt to rub on the spinning pulley sides. The bike begins to move forward. As the speed increases the weights fly out more and more. When the revs are high enough, the weights are fully out, and the belt is not slipping, or almost not slipping. When the bike slows down, the spring #7 pulls the weights back in, and the slipping process reverses.

How the starter clutch works: A manual start lever on the handlebar pulls a cable, that pulls a start lever #36 against the clutch. It moves a plates #3 and #5 inward. That forces the outer pulley half #8 to rub hard against the belt. Then moving the bike forward, either by pushing or pedaling, causes the engine to turn over, and hopefully start up (if other things are working). When the start lever is released, moving the bike forward has no effect on the engine.

More clutch info: The Colombia “belt clutch” has a needle bearing in the front pulley that allows the belt to be stationary while the engine crankshaft is spinning at idle speeds. Those needle bearings often go out, and bind. Then the bike won’t stay idling unless the rear wheel is allowed to rotate at around 5 mph. The thin needle bearing needs to be greasy, inside, but the belt that goes around it needs to be not greasy.

Another problem is high friction. As explained above, the sides of the belt are the friction surface. The trouble is, the design causes a lot of friction, so you have to push or pedal really hard. The excess friction is from the belt rubbing the pulley sides the wrong way. The belt only moves in a circular motion for half way around, then it moves across the pulley, not with it. Some people are not strong enough to get it started.

Another problem is slippage. The sides of the belt always slip a little, but they slip a lot when greasy. Then you have to pull very hard with your left hand on the start lever. The hard squeeze required eventually leads to the starter pieces wearing out fast. Once that happens, some people end up wrapping a rope around the flywheel to use as a pull starter. De-greasing the belt, and applying sticky spray for squealing belts, should help it to not need such a strong squeeze on the hand lever.

Sears Allstate

June 21, 2015

Welcome…

Sears Allstate

Sears stores in the 1950’s and 60’s carried a full line of motorcycles. Of course, Sears does not make the products they sell. The Sears Allstate 50cc Mo-Ped was made by Puch. The Sears Allstate 125cc scooter was made by Vespa. The Sears Allstate 250cc motorcycle was made by Puch (nicknamed Puch Twingle). There was also Allstate insurance, automobiles, tires, auto parts and accessories, garage door openers, fire extinguishers, and other products with that name. 

The name Allstate came from a contest held by Sears in 1925. From http://www.searsarchives.com/brands/allstate.htm, “The Allstate brand began in 1925 as part of a national contest to name Sears’ new brand of automobile tires. Public response in the contest was overwhelming. Before it was over, 937,886 people submitted a total of 2,253,746 names. Entries came from every state and in 25 different languages. Hans Simonson of Bismarck, N.D., received a $5,000 cash prize for his winning entry Allstate.”

Some Sears Allstate Mo-Ped (and early Puch or Tomos compatibles) parts can be found at Motor West Motorcycles in Milwaukee Wisconsin USA: http://motorwestmotorcycles.com/.

Welcome. Badger mopeds were made by Tovarna Rog, in the city of Ljubljana, Slovenia, formerly Yugoslavia.

Tovarna Rog in 2000's

Tovarna Rog in 2000’s

The long history of the Rog Factory (Tovarna Rog)

The industrial use of the area and the building started in the year 1871 when the Janesch (Janež) tannery started to operate. After 1900, the tannery was bought by Carl Pollak who renovated and extended the factory building, and expanded the production. The rebuilt factory is the first example of (visible) iron-concrete skeleton construction in Ljubljana. The Pollack factory worked successfully until the economic crisis in the 1930s, when the company was placed under compulsory administration of the Municipal Savings Bank, because it was insolvent. The industrial building was in use during and after the Second World War, when the Rog factory started manufacturing bicycles and typewriting machines on site (1952). The last big renovations of the building and the construction of auxiliary facilities were carried out in 1953 and 1963. The Rog factory operated on location until the early 1990s when the bicycle production was closed.

Part of the story that is not verified, was an earthquake struck the bicycle factory not long after the production of mopeds began, in the mid to late 1970’s. The earthquake destroyed most of the moped making equipment, and it was never replaced. So Rog moped production was brief. That is why Badgers are so rare in the US, because they were only made one year, pretty much. 

The abandoned 7000 square meter Rog factory was revitalized as a arts and cultural center in the 2000’s.
