Good To Know

Q: Should this be replaced every time the oil filter cover is opened? A: A fresh oil filter cover O-ring is a low-cost safeguard, since a flattened ring may not reseal once disturbed.

Q: How do I know it fits my machine? A: Match your engine and model year to the fitment list and cross-reference 420850500 before ordering.

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