description

The crankshaft is the core power transmission component of diesel engine. It receives thrust from connecting rods, converts reciprocating force into rotational torque for power output, and drives valve train, oil pump and other accessories. Journal wear, bending deformation, scoring, cracks or damaged counterweights will lead to abnormal noise, vibration, low oil pressure and insufficient power. In severe cases, crankshaft fracture causes catastrophic engine failure.

FAQ 

Q: Can a slightly bent crankshaft be reused after straightening?
A: Straightened crankshaft has hidden metal fatigue risk. It is not recommended for heavy-duty application, new crankshaft replacement is preferred.

Q: Why replace bearing shells together with new crankshaft?
A: Used bearings have different wear surface. Retaining old shells alone will cause abnormal clearance and rapid journal scoring.
