Slowly but surely I'm getting things fixed on my 1950 8N. Thanks to Y'all in advance and the highly recommended manuals. The previous owner claims to have replaced the right side axle seal only to have it start leaking again. In an automobile this is usely do to the axle having a groove in it where the seal rides. The owner claimed the axle looked ok. Are there any tricks or tips to installing these seals, part no. 8n 4251-B, and are these the only seals that keep the oil from leaking from the axle? Your time and advice is priceless! Thanks again.

The 50 8N does not have inner axle seals inside the trumpet housing as the 51 and 52 do have. That is one reason why they are more prone to leak. The spline on the end of the axle must be tight and have no loose motion in it. The 8N is famous for the alxe spline becoming worn to the point where the nut on the end of the axle will no longer have enough threads to tighten the tapered splines because part of the taper will become worn off from being operated with the nut loose. When this happens the only cure is to replace both the axle and the hub. A new nut is wise too.

The groove you mentioned is of minor concern on these outer seals that the early 8N have which turn on the hub inner surface. The main concern will be the spline being tight after the seal is replaced.

I have had good luck on these early models using silicone glue to act as an improvised inner seal inside the trumpet houshing.

If the hub is not extremely tight so that you have to have a puller to get it off I think you can replace the seal yourself. If the hub is tight that is a good sign you might get it to stop leaking.The problem with the 48 8N is that it does not have an inner seal like the 51 and 52 do. If the hub is loose on the axle and it can't be tightened because of the spline being worn too much to allow any more tightening then you will not be able to stop the leak the conventional way unless you replace the axle and hub. I hope that is not the case.

If the axle is worn too much to allow it to be tightened then you might consider my fix for the leak and leave the hub loose a few more years. To fix the leak my unconventional way you pull the axle away from the axle housing about 6 or 8 inches and wrap the axle for about 6 inches from the outer end of the axle that is exposed with teflon tape.Wipe all the oil from the housing and then take a caulking tube full of silicone glue and pump it into the void between the axle and the housing. Keep the hub as close to the housing as you can till you get the silicone pumped in.Use the whole tube and then replace the axle into the housing and replace the bolts etc. Let the silicone cure overnight and then you can go about using the tractor. Be sure that the oil in the rearend etc is not over full as this will contribute to the axle leaking.
