Oil 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. Besides keeping oil from leaking out, some are also pressure seals, keeping air in (or out). On a two stroke engine, the crankshaft seals are very important because the crankcase has the mist of gasoline, oil and air inside it. When the crank seals leak, the engine won’t idle or accelerate good. The seal inner lip has a circular thin coil spring that holds onto the rotating shaft. Click to enlarge and see the little coils of the circular spring. Metric seals are specified by their inner, outer, and thickness, in mm.

Bearings can mean ball bearings, needle bearings, and roller bearings. Needles are just thin long rollers. Ball bearings can mean individual loose balls. Or the balls can be in a ring, separate from the inner and outer races, in a “3-piece bearing”. Or everything can be all in one piece, in a “one piece bearing” or “cassette bearing”, the most common kind. The one-piece bearing shown at left, is also known as “full contact” because the balls touch the races in two wide arcs. It is also called “radial” because the center of the contact area is perpendicular or radial to the rotation. Two of the bearings listed below, L17 and E20, are “angular contact” where the contact angle is not 90 degrees to the rotation. Angular kinds are for carrying some side loads as well as radial loads.

Loose your woodruff key? You’re not alone. These tiny things have a huge importance. When a magneto flywheel key is missing, and the nut is not fully tight, the flywheel can slip and cause the sparks to happen at the wrong time.
Above, some of Myrons keys for sale, made in Germany. L to R: 3.0 x 5.0 (M-86), 2.5 x 3.7 (M-82), 2.0 x 3.7 (M-81), 2.0 x 2.6 (M-80). They look smaller because of the rounded edges, plus the ruler is closer to the camera. These are the “sharp edge type”, but not “knife edge” sharp. The “chamfered edge type” are way more rounded at the circle edges only. A chamfered key will always replace a sharp key, but only sometimes will a sharp key replace a chamfered key, of the same dimensions.

Welcome. These are the engine nuts that go on rotating shafts, rather than stationary nuts, like the head nuts. For head nuts see Engine Top End. Some are very specific and others are more universal.
