description

This 420-0456 camshaft is integrally forged from high-purity alloy steel. Cam profiles are precision ground to OEM lift curve for C15 electronic engine with deep carburizing quenching. It synchronizes intake, exhaust and fuel injection timing, fixing power loss, high exhaust temperature, valve noise and unstable idle. It performs steadily under continuous full-load mining conditions as a bare shaft overhaul part for C15 electronic engines.

FAQ 

Q：Can 420-0456 fit old C15 ACERT engine?
A：Not interchangeable. Different lift profile will cause valve interference and abnormal power output.

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 protect this long camshaft during storage?
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.
