This is a new, genuine Kubota water pump assembly, part number 1C010-73035. Kubota engine dealers list it for the V3300, V3600 and V3800 four-cylinder diesels and for the WG3800. Kubota dealer parts catalogs show it on M-series tractors, including the M6800, M9000, M8540, M9540, M100X and M105S, and on the KX080-3 excavator. It replaces 1C010-73034, 1C010-73032 and 1C010-73030, and the parts listing crosses it to Bobcat 6680852.

Kubota engine dealers list other water pumps for the V3300 and V3800 as well, such as 1K011-73036 and 1J438-73033, so match the number on your old pump. Replace the pump when coolant weeps from the drain hole, the shaft bearing is rough or loose, or the engine runs hot with a good thermostat, radiator and fan belt. The pump gasket, Kubota 1C010-73430, is a separate part number, so order it with the pump.
