description

This 338-0649 front camshaft is integrally forged from premium alloy steel. The cam lift and timing angle are calibrated exclusively for front cylinder bank. Deep carburizing and quenching on cam surface delivers great anti-fatigue and wear resistance. On dual-camshaft engines, it works with rear camshaft to synchronize air exchange and fuel injection for front cylinders, fixing misfire, power loss and timing deviation of front cylinders, suitable for heavy-duty machinery running continuously in dusty sites.

FAQ 

Q：Can I replace 338-0649 separately and keep the original rear camshaft?
A：Single replacement is allowed. Record original timing data and recalibrate engine timing after installation.

Q：What symptoms will occur if the front camshaft wears out?
A：Insufficient power on front cylinders, rough idle, abnormal exhaust temperature and occasional misfire.

Q：How to identify this front camshaft after receiving goods?
A：Check overall length, cam profile and drive end structure. This part has unique drive end for front cylinder bank.

Q：What should we pay attention to when storing camshaft?
