Oil seal for the crankcase on Rotax Max Kart Engines. This oil seal prevents clutch oil or internal crank pressure from entering or exiting the crankcase during engine operation.

The seal fits into a recessed hole in the crankcase behind the starter ring gear, and seals tightly around the crankshaft for proper engine operation.

Each oil seal is 25mm in ID, 38mm in OD, and 7mm thick.

Note: This oil seal is denoted by part (5) on the diagram. Do not confuse this with part 4 on the diagram, which is a different oil seal.
