To change the water pump on a Massey Ferguson 35 you will need some basic tools and supplies. First, you will need to remove the radiator hose from the radiator and water pump. After the hose has been removed, the water pump can be removed from the engine by removing the three bolts that secure it to the engine’s block. Once the water pump is removed, you will need to get a new gasket and sealant to seal it in place. Once the new gasket and sealant has been applied, the new water pump can be placed in the engine and secured with the three bolts. Make sure all the rubber seals are in place and the water pump is properly seated before tightening the bolts. Finally, reconnect the radiator hose to the radiator and water pump.
