This is the genuine Kubota water pump assembly, part number 1J700-73034, for the V2607 four-cylinder engine. Kubota dealers list it for the KX057-4 and KX057-5 excavators, the U55-4 and U55-5, the R530, R540, R630 and R640 wheel loaders, the SVL65-2 track loader and the SSV65 skid steer. It replaces 1J700-73030.

Change it when coolant shows at the weep hole, the shaft has play or the engine runs hot with a full radiator and a good thermostat. Kubota lists the water pump gasket as its own part, 1J700-73430. Other Kubota engines use different pumps, so match the number or give us the serial number.
