This water pump circulates coolant through the engine block and radiator to maintain the operating temperature of the host tractor. It is driven by the engine's accessory belt and moves fluid from the lower radiator hose into the water jacket around the cylinders. A failing pump typically produces a coolant leak from the weep hole or a growling noise from the bearing assembly. This original AGCO component is machined to the same impeller clearance and seal depth as the factory assembly, so no shimming or housing modification is needed during replacement. The kit includes mounting bolts and a gasket; replace the gasket on reinstall and torque the mounting bolts to specification.
