For Nissan vehicles equipped with QR20DE 2.0L and QR25DE 2.5L engines, the Oil Pump With Balance Shaft 12410-MA00C is an integrated core assembly that handles engine lubrication and vibration reduction simultaneously. This aftermarket oil pump assembly is precision cast following OEM blueprint standards, matching the original factory performance perfectly. It is a must-have overhaul component for auto repair workshops, engine rebuild factories and global auto spare parts wholesalers focusing on Nissan commercial and passenger vehicles.

What Core Functions Does This Integrated Oil Pump With Balance Shaft Perform?

This dual-function assembly combines two critical engine parts into one unit: engine oil pump and balance shaft assembly.

1. Lubrication Function of Oil PumpThe oil pump continuously circulates engine oil to all moving components including crankshaft, camshaft, timing chain and bearings, forming a protective oil film to reduce metal friction and cool high-temperature parts. A failed oil pump will lead to insufficient oil pressure, abnormal engine wear, seized bearings and permanent engine breakdown.

2. Vibration Reduction Function of Built-in Balance ShaftThe integrated balance shaft counteracts the engine’s reciprocating inertial force during operation, eliminating obvious idle shudder, steering wheel vibration and cabin resonance that commonly appear on aged QR20/QR25 engines.If your original unit suffers low oil pressure, loud engine vibration or oil leakage, replacing it with premium 12410-MA00C oil pump with balance shaft is the only thorough repair solution.
