This water pump circulates coolant through the engine block and radiator to maintain the correct operating temperature of the host tractor. It is a flange-mounted unit that replaces the original assembly in the cooling circuit. A failing pump typically produces coolant leaks from the weep hole, bearing noise, or insufficient flow that leads to engine overheating. This component is manufactured to match the original impeller geometry and flange bolt pattern, so no modifications to the mounting surface or drive alignment are needed. On installation, replace the gasket and torque the mounting bolts to specification.
