Gearbox input shaft for 150 cc 4-stroke scooters. Country of origin: China. The shaft transmits rotation from the variator to the gearbox gears and on to the rear wheel.
Replace the shaft if the splines are worn, gear teeth are chipped, the gearbox is noisy or has play, or oil is leaking. The gearbox is disassembled together with its bearings and oil seals, so it is worth replacing them at the same time. When choosing a shaft, compare the number of teeth and the splines with the old part.
