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 lead to increased vibration and a gradual loss of engine power. Continued operation risks severe internal engine damage, potentially rendering the engine inoperable.

Installation Tip

Ensure the crankshaft is meticulously cleaned and free of any debris before installation, as even microscopic particles can cause premature wear. Avoid overtightening connecting rod or main bearing caps, as this can distort the crankshaft journals.

Service Note

Always inspect and replace main and connecting rod bearings when installing a new crankshaft.
