This is a camshaft gear designed to transmit rotational force from the crankshaft to the camshaft, synchronizing valve operation.

Installation & Application Notes

Inspect mating surfaces for wear before fitting. Use torque specs from service manual. Replace gaskets and seals as a set — reusing compressed gaskets causes oil leaks. Clean all oil passages with compressed air.

Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.

Failure Symptoms

A worn camshaft gear may initially cause slightly irregular engine idle speed. As wear progresses, engine power output will noticeably decrease, and a distinct clicking or rattling sound may become audible from the engine's front cover. Failure to address this can lead to incorrect valve timing, causing severe engine damage.

Installation Tip

Ensure the crankshaft and camshaft are correctly timed before installing the new gear. Do not attempt to force the gear onto the shaft; it should fit snugly but without excessive pressure.

Service Note

Inspect the crankshaft gear and timing chain/belt for wear and proper tension during replacement.
