Repair instructions

Cleaning and inspection

Clean and inspect all parts carefully.

Sealing ring – replacement

Remove the sealing ring from the crankcase using a small screwdriver.

NOTE!

Take care to avoid damaging the crank- case.

To fit the sealing ring use the sleeve that is sup- plied with 502 50 30-16.

The end with the half moon is used for the sealing ring on the clutch side, which must be fitted flush with the surface of the crankcase.

The other end of the sleeve is used to fit the sealing ring on the flywheel side and ensures that the sleeve is fitted at the correct depth, 1.8 mm. Lubricate the sealing rings with oil.
