This is a new, genuine Kubota water pump assembly, part number 15852-73036. Kubota engine dealers list it for the D600 diesel. Kubota dealer parts catalogs show it on the G3200, G4200, G4200H and G5200H garden tractors and on the KH-007H excavator. It replaces 15852-73035, 15852-73030 and 15841-73030.
These are older Kubota engines and machines, so the surest check is the number on the 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 16851-73430, is a separate part number, so order it with the pump.
Confirm Fitment Before You Order
Kubota’s small diesels use several water pumps under different part numbers. The D722 and D902 take 1E051-73036, and the D905, D1005, D1105 and V1505 take 16251-73037 or one of its sister pumps. Send us the engine model, the engine serial number and the number on your old pump, or the tractor model and serial number. Call 530-668-0818 and we will confirm the exact match at no charge before anything ships.
