Engine lubrication primer for Cummins

The engine lubrication primer, part number 3628997, functions as an auxiliary device to pressurize the lubrication system of a Cummins engine prior to the engine cranking. By forcing oil through the internal galleries before the crankshaft begins to rotate, it ensures that oil reaches critical surfaces such as bearings and camshafts. This process establishes oil pressure before the engine fires, which is particularly beneficial for machinery that remains inactive for extended periods.

This component is engineered for integration with Cummins engine lubrication systems. It serves as a secondary pump to supplement the main oil pump during the initial startup phase. By maintaining oil flow to internal moving parts, the primer helps manage the lubrication state of the engine during the transition from a static condition to operational rotation.
