Description
The oil pump plunger is a cylindrical piston installed inside the oil pump. The main function of the oil pump plunger is to draw oil from the oil pan and deliver it under pressure to the engine's lubrication system. As the plunger reciprocates or rotates within the pump housing, it creates a pumping action, drawing in oil during the intake stroke and pushing it out during the discharge stroke.
Features
- Made of steel to withstand the high pressures and temperatures within the lubrication system.
- Ensures adequate lubrication of all moving parts
- Rockwell hardness of 30N 73 (minimum), with a case depth range of 0.3 – 0.6
- Reduces wear and heat generation, helping improve overall engine performance, service life, and reliability
Applications
The oil pump plunger sits in a cylinder or bore in the pump housing, which is sealed to maintain the pressure generated.
