Kubota D905, D1005, D1105 & V1505 (05 Series) Water Pump, 2.75 in Impeller | Genuine Kubota 16259-73036
This is a new, genuine Kubota water pump assembly, part number 16259-73036. Kubota’s parts description calls it the 05 Series water pump with a 2.75 inch impeller, and Kubota engine dealers list it for the D905, D1005, D1105 and V1505 diesels. It replaces 16259-73032, 16259-73030 and 1G642-73030.
Dealer catalogs list this pump by engine, not by machine, so order it by engine model, engine serial number and the number on the old pump. It is a different part number from 16251-73037, which Kubota also describes as an 05 Series pump with a 2.75 inch impeller, and from 16241-73037, which has a 2 1/4 inch impeller. 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 16239-73430, is a separate part number.
Confirm Fitment Before You Order
Kubota lists at least three water pumps for the D905, D1005, D1105 and V1505: this one, 16251-73037 and 16241-73037. Kubota does not publish how this pump differs from 16251-73037, so do not swap them on the description alone. Send us the engine model, the engine serial number and the number on your old pump. Call 530-668-0818 and we will confirm the exact match at no charge before anything ships.
