Good To Know

Q: How often should the oil pump screen be replaced? A: Many owners replace it during major oil system service or whenever the pump is opened, since a clogged screen can starve the engine of oil.

Q: Does this come as a complete oil pump assembly? A: No, this is the pickup screen referenced by part number 420856520, not the full pump assembly.

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