Gasket and overhaul kits
Yuchai Engine Overhaul Kit
Overhaul kits for Yuchai engines used in loaders, trucks, small mining equipment and gensets. Yuchai part numbers are tied to the specific calibration, not to the series name: YC6A covers dozens of builds such as YC6A260-T302 and YC6A240-T300, and compression ratio, pistons and head gasket thickness can differ between them. There is no single kit that covers YC4D, YC6B, YC6J and YC6A together — a four-cylinder YC4D shares nothing with a six-cylinder YC6A. Send the complete engine nameplate code and the engine serial number and we build the kit for that engine.
Turbocharger
Yuchai Turbocharger
Turbocharger supply for Yuchai engines working in construction equipment and generator sets. The turbo is matched to the power rating rather than the engine series — one YC6J family covers several ratings and each is turned with a different compressor and turbine trim. This listing also spans the 10.338 L six-cylinder YC6MK and much smaller four-cylinder YC4D units, which have nothing in common. What identifies a turbo reliably is the plate on the turbo housing itself, so send a photograph of that alongside the engine plate. Before ordering, one thing is worth checking: repeat turbo failures are almost always an oil supply or air filtration problem rather than a bad turbo, and a second new unit will fail the same way if the cause is still there.
Water pump and oil pump
Yuchai Water Pump
Cooling water pumps for Yuchai engines in construction, mining support and genset applications. This listing covers four different engines, from the four-cylinder YC4D up to the YC6108G, and the pump differs by series and usually by build within a series. Pulley diameter and groove count follow what the machine has to drive, so two engines carrying the same model code can take different pumps. Send the engine nameplate, the number cast into the old pump body, and a photograph that shows the pulley. Say also whether you want a bare pump or one with the pulley already pressed on — pressing a pulley in the field without the right tooling is the usual way a new pump gets damaged before it ever runs.
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.
