radarme 15 #1 Posted August 20, 2012 I just replaced the oil in the transmission a few months back in my '78 C-121 and now I'm realizing that I need to replace the axle seals. Do I have to drain the oil prior to removing these axle seals or is the level below the axles? thanks, David 1 Share this post Link to post Share on other sites
Coadster32 793 #2 Posted August 20, 2012 The level should be just below the seals. You can just tip the tractor up a bit on the side you're working on to make sure. Good luck with the picking! 1 Share this post Link to post Share on other sites
Lane Ranger 10,991 #3 Posted August 22, 2012 You might rig up a hub remover from the other hub on this transmission somthing like this one I set up to slowly tighten and pull the hub off the staft and woodruff key. A little PB Blaster and some good bolts on this other HUB worked for me on a five bolt hub that was stuck on a Wheel Horse axle. If you have an extra hub or one will come off easily -this is what I do to get the other hub off and to get access the the oil seal. Share this post Link to post Share on other sites
radarme 15 #4 Posted August 22, 2012 Well I guess I got lucky.... both seals had a slight leak so the hubs came off easily. Said a few choice words to the seals and they relented easily as well. All buttoned back up and ready to go! Share this post Link to post Share on other sites
