Overview – LUBRICATION PUMP AR12388RX
Engineered for Cummins lubrication positions as the lube pump pressurising oil to the engine, the Cummins LUBRICATION PUMP AR12388RX meets the tolerances your equipment was designed around.
Parts Characteristics
A lube pump 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 lube pump. Match the drive, the porting and the pressure against your old pump – lube 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 lube 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.

As a reference, the LUBRICATION PUMP AR12388RX is typically priced between USD 120 and USD 550 depending on configuration, lot size, and current exchange rates.
