Cummins 15N Natural Gas Engine Crankcase Ventilation Motor / Oil-Gas Separator Motor 6682299F
It serves as the power source for the engine's positive crankcase ventilation (PCV) system (an active oil-air separator). The motor drives the separator to rotate at high speed, using centrifugal force to efficiently separate oil particles from crankcase blow-by gases-returning the oil to the sump-while directing the gases into the intake system to be burned.
Troubleshooting recommendation: When replacing the motor, always check the connector for oil seepage (often referred to as "capillary oil leakage"). If a seal failure in the old motor has allowed oil to seep along the wiring harness into the connector, you must thoroughly clean the harness connector with electronic cleaner before connecting the new motor; otherwise, the new motor's internal drive board may be damaged.
