Lubricating oil pump gasket for Cummins 6BTAA5.9-C178

The lubricating oil pump gasket, part number 3085989, serves as a sealing interface within the lubrication system of Cummins engines. By forming a seal between the oil pump housing and the engine block, this component prevents oil leakage and maintains the integrity of the pressurized lubrication circuit. This ensures that oil is delivered effectively to critical engine components, including bearings and moving parts, to manage friction and heat during operation.

This gasket is compatible with several Cummins engine models, specifically the 6BTAA5.9-C178, KTA38C-1050, QSM11-C335, and QSM19-C700. These engines are frequently utilized in industrial cranes and heavy machinery applications. Maintaining a proper seal at the pump interface is necessary to prevent drops in oil pressure that could otherwise lead to internal component wear or engine damage.

In heavy machinery engines, gaskets of this type are used to bridge the gap between mating surfaces, compensating for minor surface irregularities to ensure a leak-free connection. They are engineered to withstand the thermal and pressure conditions present within the oil circulation system, providing a consistent barrier against fluid loss.
