so any tips. Mine are leaking, I plan to replace them. Looking at the manual it looks fairly easy, undo backing plate, yank axles, replace seal and re-assemble. Before I become too complacent anyone have any advice. Not done these seals before, first time for me
Pretty sure you have to press off the bearing to replace the seal. You might want to replace the bearings in that case.
Sorry, I haven't had that problem yet. My '61 leaks from the pinion seal. I bought a new seal, haven't tried installing it yet.
Chris, You have an inner seal & an outer seal. The inner seals are supposed to leak slightly to get lube to the axle bearing. When they are leaking badly it can over take the job of the outer seal. I usually replace the inner seal only which normally takes care of the problem. Otherwise pressing the bearings to replace the outer seals you will also have to buy bearings also. Stacey, Replacing the pinion seal is easier than most as you don't have to worry about a crush collar because there's shims for the rear pinion/yoke assembly. Just tighten the pinion nut to specs. Clean the splines on the pinion & the threaded part & also the yoke & apply a smearing of silicone to the splines & threads on the pinion for a leak free install. Tom T.
Thanks Tom, it is the inner seal and yeah the leak isn't huge, it may just be 50+ years of "gunk". I've got the drums and shoes off being machined and re-padded so while they are off getting done I thought I'd tackle this. I'm just going to go ahead and do the inners. I'm not replacing the bearings. Thanks all for the advice
well that was a piece of cake....took just over an hour to do both sides. Inner seal only. Took longer to clean all the gunk and crap off the backing plate than it did to swap em out. BUT....I may be doing them again soon. I could not get either side to go in straight and flush. I tried large sockets, PVC pipe and a chunk of wood. On both side, one third of the seal in "in" about 2-3 mm more than the rest. The rest is flush. I suspect that over time tis will wear the rubber part pf the seal unevenly and it will leak again. So ordering two more and will be prepared to do it again soon. But now that I've done it once and it's such as easy job, not concerned. Will have to figure out a better instal technique though
