Overview – OIL PUMP ASSEMBLY 4095082-20 Series
The Cummins OIL PUMP ASSEMBLY 4095082-20 is part of a proven family of components used across Cummins lubrication positions as the engine oil pump assembly, and several interchangeable part numbers share the same fitment.
Parts Characteristics
An oil pump assembly that draws the oil and pressurises it to every bearing and clearance in the engine, carrying the lifeblood that keeps metal from touching metal. It is the heart of the lube system, so a true, primed pump keeps the pressure up and the engine alive.
Applicable Models & Applications
Used at Cummins lubrication positions specifying this oil pump assembly (series). Match the drive, the porting and the pressure against your old pump – oil pumps differ in how they drive and seal.
Maintenance & Replacement
Inspect the gears or rotor for scoring and the relief valve for free movement at every service. A pump that has begun to lose pressure starves the bearings, and the starvation is what scores the crank.
Prime the pump before start so it does not run dry. A pump spun up on air loses its prime and the first seconds are the ones that wipe a bearing.
Confirm the drive and the pressure on fit. A pump driven wrong or set soft never reaches the spec and the gauge sits low.
Keep the correct oil pump for your engine on the shelf. It is load-critical, and an engine stopped on oil pressure is an engine waiting on a part.
