Hi! I’m trying to find parts for this. Not much luck, so far. The outer seal is combined with a flange. It must’ve been doing it’s job because the bearings are nearly dry. However, I haven’t checked diff level. The inner seal is stationary and has a felt lip on the perimeter. Both seals are weird in my world. The outer seal has National 6234 on it. I’m used to too much gear oil getting on the brakes not the other way around. Jim Carter, etc is telling me to just reuse old seals. Against principles! Thanks, Don
Hy Monsonmotors, welcome, by looking at the orientation of the seal lip on the seal in your picture, I would say it is designed to keep differential oil out of the hub. Most likely the hub bearings were supposed to be lubricated with grease when they were assembled and the seals kept the oil from washing the grease out and letting the oil contaminate the brake shoes. I know it goes against what we were taught, but if the seal lip is in good condition you could reuse it. I will spend a bit of time searching for new seals for you.
Thank you so much for making me think I’m not crazy. These rear bearings are going to be packed like front bearings, for sure. On the plus side, the drum and shoes are dry. The truck itself is a locally historic tow truck. Amazing it survived.
