INNTECK crankshaft oil seal for HONDA CR 250, CR 500 from 1986 to 2007.
The INNTECK OS106 crankshaft oil seal is designed for HONDA CR 250, CR 500 from 1986 to 2007. The crankshaft oil seal seals the point where the crankshaft comes out, on the ignition side or the clutch side. On a two-stroke, it keeps the crankcase airtight: a leak draws in air or gearbox oil, and the engine runs badly.

Do the crankcases have to be split?
Not always: on some engines, the ignition-side seal can be replaced without splitting the cases. During a rebuild, replace it along with the crankshaft bearing and seal kit.
