Tonight I went out into the garage to fit the oil pan side gaskets so I could put the timing cover in place. Being a responsible Studebaker owner, I decided to replace the rear main bearing seal while I was in there, even though the old one didn't show signs of leaking. To remove the rear main seal, I carefully removed the oil pump so I could access both bolts on the rear main bearing cap, then loosened the middle 3 main caps per the shop manual and then removed the rear cap.
Everything looked very good--there was little if any sign of wear on the rear main bearing, and the seal was still supple and sealing well. I carefully removed the seals halves, put in a new ones and torqued down the bearing caps.
I was snugging down the last nut on the oil pump with a small hand wrench when I heard a loud crack and the nut spun freely. I had broken the stud.
