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

The Oil Pump 8-98017585-1 is a high-precision lubrication system component engineered to deliver consistent oil pressure and circulation to all critical engine parts in Isuzu diesel engines. Proper lubrication is essential for minimizing wear, reducing heat, and extending the life of internal engine components such as bearings, camshafts, crankshafts, and valve train assemblies.

Manufactured to OEM specifications, this oil pump features durable internal gears, a high-strength housing, and precision machining to withstand the demands of diesel engine operation in trucks and industrial equipment. It is built to provide continuous oil flow and pressure from cold starts through extended heavy-duty use.

This oil pump is a direct replacement for Isuzu part number 8-98017585-1 and is compatible with multiple Isuzu engine platforms including 4HK1, 4JH1, 4HF1, and 4HK1-TCN. Whether used in commercial truck applications, construction machines, or industrial engines, this pump restores optimum lubrication performance and protects against premature engine wear or failure.

A faulty or worn oil pump can lead to low oil pressure, increased friction, overheating, and potential catastrophic engine damage. Replacing it with this OEM-grade unit ensures reliable performance, consistent oil pressure, and long-term engine health.
