Specs At A Glance

Good To Know

Q: What tells me the oil pump rotor is worn out? A: Low oil pressure, metal particles in the oil, or a whining oil pump usually mean rotor wear, so check the rotor faces for scoring or pitting during teardown. A: A rotor with visible wear should be swapped out rather than reused.

Q: Is this the complete oil pump or just the rotor? A: This listing is for the oil pump rotor only, so verify whether you also need the housing, shaft, or seals for your rebuild. A: Cross-reference 420956675 confirms the correct match for the 1503 engine oil pump.

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