description

This 421-0200 camshaft is integrally forged from vacuum refined alloy steel. Cam profiles are precision ground to OEM lift curve for C32 engine with deep carburizing quenching. It coordinates intake, exhaust and fuel timing for V-type C32 engine, fixing unstable power, abnormal exhaust temperature, gear housing noise and rough idle. It suits continuous full-load dusty mining operation, serving as bare shaft overhaul part for C32 engine, different from separate left/right bank camshafts.

Part No.：421-0200
Name：Engine Camshaft
Material：Carbon Steel
Process：Integral forging + carburizing quenching + multi-station precision grinding
Package：Bare shaft, timing gear, bearings and tappets sold separately
Application：Cat C32 engine, 777 mining truck, large generator set

Product Advantages

1. Timing phase matched for C32 whole engine calibration, not interchangeable with separate left/right bank camshafts
2. Deep carburized hardened layer, good resistance to pitting and peeling under continuous high temperature and heavy load
3. Strict concentricity control for long shaft, reduces uneven journal wear and extends overhaul interval
4. OEM identical drive end datum, smooth gear meshing and less transmission noise
5. Each piece inspected on runout, hardness and cam profile, suitable for bulk stock for mining and power station service

FAQ 

Q：Can 421-0200 replace 421-0155 and 421-0176 left/right bank camshafts?
A：Not interchangeable. Different structure and timing phase will cause valve collision and power imbalance.

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

Q：How to store this extra-long camshaft properly?
A：Hang vertically, apply anti-rust oil, cover with dust film and avoid horizontal bending pressure.

Q：Is oil and filter change recommended while replacing this camshaft?
A：New engine oil and filter are recommended to protect new cam lobes from metal debris.
