Good To Know

Q: Why does an oil pump rotor need replacing? A: Rotor lobes wear against each other over time, which reduces oil pressure and can cause engine damage if left unaddressed. Replacing the rotor restores proper oil flow.

Q: Should both rotors be replaced at the same time? A: Replacing inner and outer rotors as a matched set is standard practice because they wear together. Confirm the rotor pairing for your specific engine 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.
