New to the forum, I'm working on the first tractor that my Grandpa bought new back in 1937 it is a un-styled AR and showed up on the farm two months before my Dad was born. It has stayed in the family all these years but hasn't been running in many. my brothers and son and I have been going through it and we are getting it close but there are a couple of oil leaks in the rear end so we took the rear end housing off. Has anyone changed axle seals on one of these before? It looks pretty straight forward, although I'm not even sure they are leaking and don't know if I should get into them other than I'm into it this far and it just seems like the right thing to do.
