Cummins 4953337 Crankshaft Timing Gear

The Cummins 4953337 crankshaft timing gear is a critical internal engine component designed for the K19 and QSK19 heavy-duty diesel engine platforms. It mounts on the crankshaft nose and drives the camshaft gear train, ensuring precise valve timing synchronization. Manufactured to Cummins OEM specifications using forged alloy steel with induction-hardened gear teeth for maximum wear resistance and fatigue strength under high-torque industrial applications. This gear replaces superseded part numbers 4953166, 3090484, and 3090048. It is utilized in construction machinery, marine propulsion, and power generation equipment powered by the 19-liter Cummins engine series.
