description

This 421-0119 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 synchronizes intake, exhaust and fuel injection timing, fixing insufficient power, abnormal exhaust temperature, valve noise and unstable idle. It is suitable for continuous heavy-load mining, marine and power station operation as a bare shaft overhaul part for C32 engines.

FAQ 

Q：Can 421-0119 interchange with C18 camshaft?
A：Not interchangeable. Different shaft length, lift and journal size will cause valve collision damage.
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 camshaft?
A：New engine oil and filter are recommended to protect new cam lobes from metal debris.
