Reply To: Re installing oil pump

[George Teebay]

This pertains to Series 80 & 81. Jim, I’ve been there and done that, and the thrashing 1/2-inch square tube (replacement at hardware store) broke into several pieces, necessitating dropping the pan. Suggest you remove the six oil pump studs and replace them with capscrews (1/4-20). Pay attention to the length, because three holes are blind and a too-long capscrew will break the pan casting. You will have an additional 3/4 inch to juggle the oil pump body to thread the round pilot tip into the square hole and can feel the drag when the square portion of the pump shaft engages the square tube. I further recommend flat washers and toothed washers under the heads, plus sealant on the threads of the three open-hole capscrews.
