JimSraj 429 #1 Posted April 8 Can the brake shaft seal on a 1991 312-8 be replaced without splitting the transmission? Share this post Link to post Share on other sites
WHX?? 48,815 #3 Posted April 8 (edited) Yep just pick the old one out. Tape the keyway to avoid nicks. Grease & carefully tap the new one in with a piece of pvc 1 1/4 I think? Edited April 8 by WHX?? 2 Share this post Link to post Share on other sites

I also use a very big washer up against the oil seal as you pop the PVC pipe piece with a rubber mallet! 3 Share this post Link to post Share on other sites
ebinmaine 67,502 #5 Posted April 8 I often file the keyway groove so that's not the tough part for me. The lock ring groove on the outside can be really tough to get a seal past. I think the last time I used HD packing tape to cover the groove. Grease the seal well. Share this post Link to post Share on other sites

ri702bill 8,322 #7 Posted April 8 Jim - not totally necessary, but it helps to remove the tire on that side (duh) and raise that side higher than the other so as not to loose fluid..... 1 Share this post Link to post Share on other sites
JimSraj 429 #8 Posted April 8 Definitely be removing the wheel and that side will be raised up. It’s low on gear oil now so hope not to lose any. Thanks for the reminder though. 2 Share this post Link to post Share on other sites
