Hey all,
Looking for a pilot bearing for my 41 with 54 235. From my search, it appears as though GM has used the same pilot bearing since the beginning of time. I have found several variants and still have not found a winner. The original was a oilite bronze bushing.
Some on the market a sintered iron and bronze but without specific verbiage indicating if they are oiled.
I have found a National PB-656-HD bushing that seems correct non-ferrous but the physical part is not wrapped in wax or plastic wrap leading me to think it is not an oilite. The current GM part is Delco CT1088 and it is oil impregnated, but it has "relief" cuts in the ID which Novak states increased wear.
Any intel on this is appreciated.
Paul
