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 connecting rod bushing may include a distinct knocking or tapping sound from the engine, especially under load. If ignored, the noise will likely increase in severity, accompanied by a noticeable drop in oil pressure and potential engine performance issues. Continued operation risks severe damage to the crankshaft and connecting rod.

Installation Tip

Ensure the crankshaft journal is meticulously cleaned and free of any debris before installing the new bushing. Avoid using excessive force or improper tools, which can distort the bushing and compromise its fit.

Service Note

Inspect the crankshaft journal for wear or scoring, and check connecting rod bolts for stretching or damage when replacing the connecting rod bushings.
