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 failing crankshaft may initially present as a persistent knocking sound from the engine block, especially under load. If ignored, this can progress to increased vibration and a significant reduction in engine performance. The ultimate consequence is potential engine seizure, leading to extensive and costly repairs.

Installation Tip

Ensure the crankshaft journals are meticulously cleaned and free of any debris before installation. Avoid overtightening main bearing cap bolts, as this can distort the crankshaft and lead to premature failure.

Service Note

Always inspect main and connecting rod bearings for wear and damage when replacing the crankshaft.
