description

This 431-5029 camshaft assembly is forged from alloy steel. Its cam profile is developed for diesel combustion, matching fluctuating industrial load. Timing gear, locating bushing and thrust plate are pre-assembled for direct fit. It synchronizes valve opening and fuel injection timing, solving slow throttle response, low-speed smoke, gear noise and rough idle. It is built for stationary equipment such as pump sets and crushers with intermittent shock load, not interchangeable with G3516C gas camshafts.

Part No.：431-5029
Name：Camshaft Assembly
Material：Corrosion Preventative Fluid
Process：Integral forging, carburizing quenching, precision grinding, dynamic balance calibration
Package includes：Camshaft body, timing gear, locating bushing, thrust plate
Application：Cat stationary industrial diesel engine, mine pump station, crusher power unit

Advantages

1. Diesel-specific profile, balancing low-speed torque and fuel injection window for intermittent shock load
2. Built-in thrust limiting structure, resisting axial movement during frequent load change and protecting gear surface
3. Thick hardened cam surface, anti-pitting and anti-spalling under sudden load impact
4. Factory dynamic balance treatment, reducing vibration and abnormal bearing wear
5. Complete assembly, thrust parts included, cutting on-site overhaul time

FAQ 

Q：Can 431-5029 diesel camshaft assembly replace G3516C gas camshaft?
A：Not interchangeable. Different fuel strategy, cam angle and timing base will cause combustion disorder and valve collision.

Q：Can the camshaft be reused after light journal scratches polished?
A：It can be used temporarily within tolerance. Deep grooves require replacement to avoid seizure.

Q：How to store this camshaft assembly?
A：Hang vertically, apply anti-rust grease on gear teeth and cams, cover dust cover and avoid gear impact.

Q：Is oil and filter change recommended after replacement?
A：Recommended, to prevent metal debris from scratching new cam lobes.
