Ok I finally corrected the direction of the special square headed bolts and have the dust/grease shields oriented correctly, another question as a follow up to the Nylock question.
Originally it had nuts that looked kind of like a castle nut, but without complete slits. and also there are no holes for a cotter pin going through the special square headed bolts, so there's no provision for a cotter key anyway...yesterday I asked if I could replace these old nuts with Nylock nuts, but because of the length of the bolts, I'm not sure how well the bolt will engage the Nylon insert, so would I be able to use the same size jamnut (1/2 x 20)with red loc-tite and accomplish the same thing?
These are the 4 bolts that hold the backing plate onto the spindle.
Thanks again,
Randy
