John Deere Model 50 Rear Axle Seals

Jim R · Oct 14, 2014

I have a 1956 John Deere Model "50" tractor that I use fairly often, for hayrides, shows etc. The right rear axle seal has started slobbering gear oil in the inside of the rear wheel. Can anyone out there tell me how much of a job and what is involved in reapiring the leak, since I have never done it before?? Thanks in advance for any advice!

Take 1 gal of oil out of the rear end. Should be a plug above the seal area on the axle put a grease zerk in there and give it about 5 shot of grease. Did that to mine and it quit leaking, been about 10 years. I never pulled the axle. If you have to much oil in the rear end it could be your crank shaft seals, I have replaced them.

If you decide to do it,, it requires removing the rockshaft housing, loosning the two large nuts holding the axel to the bull gears. Jacking one wheel up at a time, removing the wheel, then using a wedge between the two large nuts, tap it with a hammer, and push the axel outward. Untill you can remove that nut, then push and pull the axel out, remove the bull gear, the seal is just inside the housing. Inspect the bearings and races, then put it back togather, carful not to damage the new seal.

Thanks so much for the advise! The suggestion that it could be crankshaft seals makes sense as it seems like the tractor is using some oil and I couldn't tell where it was going. It's not smoking. I will investigate further! Jim
