description

This 382-3702 camshaft assembly is integrally forged from vacuum refined alloy steel. Cam profiles are precision ground to OEM lift curve for C9.3 electronic engine with deep carburizing quenching treatment. It comes pre-assembled with timing gear and spacer sleeves for direct fitting. It synchronizes air exchange and fuel injection accurately, fixing timing drift, insufficient power, rough idle and valve noise. It works reliably under hot, dusty and continuous running conditions as a complete overhaul assembly for C9.3 engines.

FAQ 

Q：Does 382-3702 fit old mechanical pump C9 engine?
A：Not interchangeable. It only fits electronic C9.3. Check engine serial number before ordering.

Q：Can the built-in timing gear be detached and replaced separately?
A：It is pre-positioned at factory. Disassembly is not recommended, as it breaks original timing datum.

Q：Can the camshaft be installed with tiny pits on cam lobes?
A：Pits will expand rapidly and damage tappets. Replacement is required to prevent secondary engine failure.

Q：How to store this camshaft assembly for long term?
A：Hang vertically, apply anti-rust grease on gear teeth, cover with dust film and avoid impact or heavy load.
