Product Overview
A leaking seal, rough bearing or worn impeller can reduce coolant circulation and cause overheating. This pump restores the belt-driven coolant flow needed to keep the engine at a safe operating temperature.
Matching applications include Yanmar YM1700, YM2000, YM2010, YM2210, YM2310, YM2500, YM2610, YM3000 and YM3110, plus John Deere 850, 950 and 1050. One important fitment detail is the fan-hub diameter: many listings specify a 2-inch hub, while some Yanmar tractors used a 2-1/4-inch hub.
