4935792 Oil Pump Ass'y for Cummins 6BT Komatsu PC200-6 Hyundai R210LC

Restore Peak Lubrication for Your 20-Ton Excavators & Loaders

The 4935792 Engine Oil Pump is an industrial-grade, precision-manufactured replacement component designed specifically for the heavy-duty demands of 20-ton class excavators and high-capacity wheel loaders. In continuous earthmoving and quarry operations, your engine's lubrication system is its only defense against catastrophic failure. A worn oil pump leads to immediate drops in oil pressure, risking severe thermal damage to the crankshaft and turbochargers. This heavy-duty gear-driven assembly restores OEM-spec volumetric oil flow, ensuring your heavy equipment remains highly productive under maximum breakout force.

Primary Heavy Equipment Fitment:

• Komatsu PC200-6, PC220-6 (Equipped with S6D102 Engines)

• Hyundai R210LC-7, R220LC-7, R225LC-7

• Liugong 856 and XCMG Heavy-Duty Wheel Loaders

Precision Engineered for the Legendary Cummins 6BT 5.9L

This robust oil pump is engineered as the mechanical heart for the legendary Cummins 6BT (5.9L), along with the later ISB and QSB 5.9L diesel platforms. It is also the direct replacement for the Komatsu S6D102, which shares the identical engine architecture. Featuring precisely machined helical gears and a durable cast-iron housing, the 4935792 provides instantaneous, high-volume lubrication to maintain a stable oil film thickness on the main bearings and overhead valvetrain, keeping your 5.9-liter powerhouse thermally balanced.

Professional Installation Notice

Before installing the 4935792 / 3926203 oil pump onto your Cummins 5.9L or Komatsu engine block, thoroughly inspect the engine's main timing gear train for any abnormal wear or excessive lash. Due to the critical nature of the lubrication system, we strongly advise a complete engine oil pan flush and filter replacement to remove metallic debris from the prior component failure. Always utilize new OEM-specified mounting gaskets and torque all hardware to Cummins factory specifications to guarantee a permanent, leak-free operational seal.
