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.
Types: SR = Square Ring, VC = V-lip Coated, SC = Spring-lip Coated, TC = Two-lip Coated, DC = Double-spring Coated
