Is that the differential seal? Talked with Ron at TM and he said to go ahead and replace the differencial. It appears that on the right side of the tractor the leak is coming whre the final bolts on and then just travels down the final and the inside of the rear wheel.

Yes, that seal is the differential seal...official name: DIFFERENTIAL SHAFT INNER BEARING RETAINER OIL SEAL.

It is probably still the differential seal leaking, but the fluid has to go all the way to the right side near the final where there is a drain hole, and again, this is right near the right brake band.

Generally, the first thing you do is check the transmission gear oil level, and if it is too full, drain and refill with the correct 3 1/2 pints. Clean up the final area and see if that resolves the leaking issue.

If not, then get ready to pull one final at a time (there is a very good HOW TO) and replace the seals. While off, check and clean/replace the brake linings if oil covered or worn out. If only oil soaked, you can remove the brake, and using a prolane torch, set the lining on fire. Honest, it works. Just keep it burning until it look nice and clean!

Good luck!

Copy have the stuff ordered from TM, just waiting till mowing season is over. Hopefully can get it down after mowing but before it snows as want to push snow with it.

Yes I mis-spoke that is what I drained and refilled to the correct level and it still leaked out. Hopefully the seal will fix.

You are lucky...you are less than 2 hours from The Barnyard...location of one of the best Cubfests! If you can attend one of these events, they are invaluable! Great fun meeting forum members, getting advice, eating good food, telling tales...oh yeah, and working on cubs!!!

If you can take your cub (or parts like carb, final, transmission, etc) there's an excellent chance to get things rebuilt while there! Lots of knowledgeable folks who love to share their expertise!

At the very least, you are surrounded by forum members, so if you need help, you might even have your own Mini-Fest at your place..."invite them and they will come"!! Oh, and bribery may help, too...donuts for some, :coffee: or :beer: for others!!! :big smile:
