The crankshaft converts the reciprocating motion of the piston into rotation and transmits torque to the transmission. Brand: SEE.
It should be replaced if the big end of the connecting rod has play, there is knocking or vibration, or the journals and splines are worn. Replace the crankshaft bearings and oil seals at the same time. When replacing it, also inspect the neighboring parts of the assembly: they wear together.
