Fuel injector and fuel pump
Yuchai Fuel Injector
Fuel injector matching for Yuchai diesel engines, quoted by engine nameplate and injector part number. Yuchai injectors follow the calibration, not the series: YC6A alone covers dozens of builds such as YC6A260-T302 and YC6A240-T300, and injector flow rating differs between them although the engine looks the same from outside. The four-cylinder YC4E and the six-cylinder YC6L share nothing here. We ask for the number stamped on an injector already fitted as well as the engine nameplate, because on a machine that has been repaired before, what is in the engine is often not what left the factory, and matching the running set matters more than matching the original specification. Injectors are supplied as a set for a reason: one new injector against five worn ones leaves the engine running unevenly and the new one doing more work than it should.
Starter and alternator
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.
