This is a heavy-duty crankshaft, the main rotating assembly within the engine that converts reciprocating piston motion into rotational torque. It is precision-balanced and engineered to withstand extreme combustion forces and high rotational speeds. A damaged or worn crankshaft can lead to severe engine imbalance, bearing failure, and ultimately, catastrophic engine damage.

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.
Initial symptoms of a failing crankshaft may include unusual knocking or rumbling noises from the engine's lower end, especially under load. As the damage progresses, you might observe significant oil pressure drops or visible metal particles in the engine oil. Continued operation with a compromised crankshaft risks severe internal engine damage, potentially leading to a complete engine seizure.
Ensure all crankshaft bearing journals are perfectly clean and free of any debris or scoring before installing new bearings and the crankshaft. Always use new, correctly torqued main and connecting rod bearings.
When replacing a crankshaft, it is mandatory to replace all engine bearings (main and connecting rod), oil pump, and all seals.
