Oil Pump 8-98017585-1 for Isuzu 4HK1 4JH1 4HF1 4HK1-TCN Engines

The Oil Pump 8-98017585-1 for Isuzu Engines is a precision-engineered lubrication system component designed to deliver consistent oil flow and pressure throughout the engine’s critical bearings and moving parts. Proper lubrication is essential to maximize engine longevity, minimize wear, and support stable operation under high load and extended duty cycles.

Manufactured to OEM specifications, this oil pump features hardened internal gears, a high-strength housing, and precision machined surfaces to withstand the rigors of diesel engine operation. It provides efficient pressurization of engine oil, ensuring that all vital components — including crankshaft journals, camshaft bearings, lifters, and valve train components — receive proper lubrication from initial start-up through heavy-duty cycles.

This oil pump is a direct replacement for Isuzu part number 8-98017585-1 and is compatible with a range of Isuzu engines including 4HK1, 4JH1, 4HF1, and 4HK1-TCN. Whether used in medium-duty commercial trucks, industrial equipment, or marine applications, this pump is essential for engine rebuilds, maintenance, and repair.

A failing oil pump can lead to low oil pressure, increased friction, accelerated engine wear, overheating, and catastrophic engine failure. Replacing a worn or damaged oil pump with this OEM-grade unit restores proper lubrication performance and protects your investment.
