Anyone with experience in old BC type gearboxes
They used to be notorious for the diff bearings going, and back in the day I replaced many the bearing. However, in my 1990 XR2i, I changed the input shaft bearings, and the diff seals. No biggie, but when I put the casing back together, each side didn't sit flush. It was as if there was something stopping them from closing together. I can close them if I tighten the bolts, but should that be the case? It's so long since I opened a BC gearbox I forgot if this is normal, and if tightening the bolts just sets the preload on the diff bearings. I've stripped the box back a few times since in case I'm missing something, but I can't see if there's somethinmg wrong. If I leave just the diff in, and close the casing by tightening the bolts, the diff becomes harder to turn, but if I have the gears in, I can turn the input shaft by hand, and the diff is turning, but if I go with it as is, and it's wrong, those bearing won't last long. Any advice?
