The OEM DCEC Cummins Crankshaft Gear 4934418 is a precision-manufactured timing component designed for Cummins 4B, ISB, 6B5.9, B4.5, and B6.7 (6.7L) diesel engines. This gear mounts directly onto the crankshaft and plays a critical role in driving the engine timing system, ensuring accurate synchronization between the crankshaft, camshaft, and fuel system components.

Manufactured by DCEC (Dongfeng Cummins Engine Company) to OEM specifications, this crankshaft gear is produced from high-strength, wear-resistant alloy steel to withstand continuous rotational loads, high torque, and thermal stress. Proper gear tooth profile and hardness ensure smooth engagement with mating gears, reducing noise, vibration, and premature wear.

A worn or damaged crankshaft gear can cause incorrect timing, excessive noise, poor engine performance, and potential internal engine damage. Replacing it with the new OEM 4934418 crankshaft gear restores precise timing control, protects critical engine components, and ensures long-term reliability. This part is ideal for engine rebuilds, timing repairs, and preventive maintenance in on-highway, off-highway, and industrial Cummins engine applications.
