PRODUCT DESCRIPTION
Genuine C4939585 DCEC Cummins Engine Oil Pump
This OEM C4939585 oil pump assembly is authentic DCEC Cummins spare parts for engine lubrication system. The cast iron pump body and precision hardened rotors maintain steady lubricating oil pressure at low and high engine speed. Continuous oil supply effectively cools and lubricates crankshaft, bearings and camshaft, reducing metal friction loss. Original mounting structure allows simple direct installation on matched Cummins heavy‑duty engines. This heavy‑duty engine spare part guarantees reliable lubrication during long‑haul and high‑load operation.
Replace Worn Oil Pump To Avoid Engine Damage
A worn, leaking or inefficient oil pump causes insufficient oil pressure, dry friction, overheating and serious engine seizure for DCEC Cummins engines. Our genuine C4939585 oil pump assembly solves common failures including rotor abrasion, internal oil leakage and unstable oil pressure. It restores normal lubrication circulation and prevents expensive engine breakdown. It is ideal aftermarket Cummins spare parts for regular engine overhaul and fault maintenance of heavy‑duty trucks.
Original DCEC Standard & Strict Pressure Performance Test
The C4939585 engine oil pump assembly is manufactured following official DCEC factory standards as qualified Cummins engine spare parts. Each finished oil pump undergoes oil pressure test and leak detection before packing. Precision machining ensures tight rotor clearance and minimal pressure loss. Hardened alloy rotors greatly improve wear resistance and service life under continuous heavy‑load working environments, trusted by many logistics fleets and engine repair workshops.
