Specs At A Glance

Good To Know

Q: How do I know if my crankcase cover O-ring needs replacing? A: Oil weeping at the crankcase cover seam or a flattened, cracked, or hardened O-ring during inspection are the usual signs. Replacing it whenever the cover is removed is good practice.

Q: Should I lubricate the O-ring before installation? A: A light coat of clean engine oil helps the O-ring seat without twisting or pinching. Seat it evenly in the groove before tightening the cover.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
