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.
