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

Initial signs of a failing crankshaft gear may include intermittent engine misfires or a slight loss of engine responsiveness. As wear progresses, the engine may run rougher, and audible clicking or grinding noises could emanate from the front of the engine. Continued operation with a damaged gear risks severe engine timing disruption and potential internal damage.

Installation Tip

Ensure the crankshaft and camshaft are correctly timed before installing the new gear to avoid incorrect synchronization. Do not overtighten the mounting bolts, as this can damage the gear teeth or mounting surface.

Service Note

Inspect the camshaft gear and timing belt or chain for wear and replace as needed when servicing the crankshaft gear.
