Pump gears and body do not make any requirements for service individually; if they become worn or damaged, the total pump will need to be replaced. Start with the mere removal of the pump cover retaining screws, the cover as well as noting the positions of the gear teeth so that they may be reinstalled in their intended positions. Then, remove idler gear and drive gear and shaft from the body, later pressure regulator valve retaining pin, valve and some related parts. If so required, only the pick-up screen and pipe assembly can be unbolted and pulled out of the pump body. In cleaning, immerse all parts in a solvent and dry them satisfactorily, scrutinizing the body on any signs of crack or wear or damage as well as the gears. Check the revolve of drive gear shaft; looseness in the face of the pump body for sanctions of typical vibrations; and, examine the inner surface of the pump cover for wear which might bring about oil leakage. Also check the pick up screen and pipe assembly for damages. Put on the gasket sealant on the terminal end of the pipe and insert into the pump body without damaging it; if the direct press-fit is not achievable, a rear assembly has to be done to minimize loophole in the pipe that may cause air leaks and loss of pressure. Place the pressure regulator valve and other componentaries as well as the drive gear and shaft in the pump body; the idler gear placed in such a manner that the smooth side faces the opening of the pump cover. All blind holes in the pump and between the gears are to be packed with petroleum jelly to facilitate priming. Last, put the cover on and fasten the screws, after that rotate the drive shaft to ensure that the pump is not bound.

Disconnect the steering idler lever at the frame and swing the linkage down clear of the oil pan.

Begin by assembling the pump and extension shaft to the rear main bearing cap, ensuring that the slot at the top end of the extension shaft aligns with the drive tang on the lower end of the distributor shaft if the distributor is in place.
