Yuchai Starter Motor

Starter motors for Yuchai engines, checked by voltage, mounting type and engine model. Four things decide the part and the engine model is only one of them: system voltage (12 V on the smaller four-cylinder builds, 24 V on most six-cylinder and genset applications), the number of mounting bolts and their spacing, the tooth count on the pinion, and whether the unit is reduction geared or direct drive. Count the pinion teeth and the mounting bolts on the old unit before ordering; those two numbers settle most enquiries on their own. One diagnostic point: if the engine turns over slowly rather than not at all, check the batteries and the earth strap first. A large share of the starters we are asked to replace are working correctly.
