The crankshaft converts the reciprocating motion of the piston into rotation and transmits torque to the transmission. Brand: GXmoto.
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. If you have the old part, compare it with the new one for dimensions and mounting points before installation.
