Seals

July 13, 2014

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.
