Hey Gearheads, I just got finished rebuilding the tranny on the 37 ULH. I took it apart because the mainshaft keyway slot was bugeered up. Had never been apart, and I ran into something I've never seen before, which was the 3rd gear mainshaft bushing on the early tranny's (36/37 I'm assuming) have a smaller O.D. than the later (currently made) ones. This was a head scratcher as every one I've rebuilt never had this problem. Around .040" too big. The bushings that are available all have -38 part numbers, so I assume that they changed the gear to a larger I.D. and the bushing to a larger O.D. JIMS, Eastern and V-Twin all carry the later bushing, as far as I can tell nobody carries the early one. I removed the offending bronze in my lathe, pressed it in and sized all the bushings with a Sunnen LB hone. Everything is back in spec now, but does anyone know if the early bushings are made? Thanks
Steve
