description

This 423-7586 camshaft assembly is integrally forged from high-purity alloy steel. Cam profiles are precision ground to OEM lift curve for C18 engine with deep carburizing quenching. The timing gear is pre-assembled for direct installation. It synchronizes intake, exhaust and fuel timing, fixing power loss, high exhaust temperature, gear noise and unstable idle. It fits continuous heavy-duty dusty open-pit mining operation, complete timing assembly for C18 engine, no separate timing gear needed.

FAQ 

Q：Can 423-7586 camshaft assembly fit C15 engine?
A：Not interchangeable. Different lift, journal size and gear teeth will cause valve interference.

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 camshaft assembly properly?
A：Hang vertically, apply anti-rust oil on gear teeth and cam lobes, cover with dust film and avoid impact.

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