4003950 | Cummins M11 Oil Pump, New L10/M11/ISM

Diesel engine oil pumps are responsible for circulating oil throughout the engine to lubricate moving parts and reduce friction. The oil pump pulls oil from the oil pan and pushes it through the engine's oil passages, ensuring that all components receive proper lubrication.

 

The oil pump should be inspected and replaced as part of routine maintenance. Symptoms of a failing oil pump include low oil pressure, engine noise, and poor engine performance. If these symptoms occur, the oil pump should be checked immediately as it can cause serious engine damage if left unchecked. 

 

Ultimately, the replacement interval of an oil pump depends on the engine's usage and manufacturer's recommendation. It's crucial to follow the manufacturer's recommended maintenance schedule to ensure the longevity and reliability of the engine.
