Brake bands on H

I pulled off the covers and found that one of the bands was thin, but the other was new. Both was covered with oil. What can I clean the good one with, and is it worth it, and What is shot behind the brake wheel that is letting in the oil to begin with. How hard is it to get off the band wheels, and replace whatever needs replaceing, and where can I get the parts to replace with? Thanks for your time. Bill

THe bands may be saveable, you can clean them off with brake parts cleaner. The bull pinion seals have failed and need to be replaced. They are quite a job to complete. I would get a service manual if you dont have one already it will have a good break down on how to do it. All parts are out there though CNH, and many aftermarket sellers, even napa will have those seals.

To replace the seals you must drop the bull gears off the axle to get the bull pinion carrier out. Plus you have to pull the axle to drop the bull gear . Now some say to remove the top deck to do this , but YOU CAN DO THIS THRU THE PTO HOLE You can remove the PTO and get a 3/4 drive breaker bar in on the axle bolt that holds the bull gear to the axle and using the wheel to break it loose and back it out.But if you have really big arms then it can be hard to put the bolt back in . You will need a good jack to jack up and blocking to support the back end of the tractor and a Cherry picker to handle the tire wheel and axle as a unit or you can pemove the tire and wheel from the axle after you get the bolt out and set it off the side and then hook to the axle housing and slide it offand while you have it off now is a good time to look over the axle bearings and do any fixen there . Then once the bull gear has dropped off then you can remove the carrier one side at a time . What you do not want to happen is for the ring gear and carrier to drop down in to the bottom .

Nope, that aint gonna happen lol. Ill just keep cleaning the brake bands and replaceing them when necessary. WHOLE lot easier and quicker, and no chance of messing up. Thanks for the advice

You don't have to take the whole tractor apart to fix your oil problem. There is an oil seal behind the brake drum that is easy to fix. If I remember correctly there is a bolt on the end of the drum that comes out and the drum slides off the shaft. The oil seal is right there. If there is oil leaking from the bull gear holder (not sure exactly what that part is called) that requires removing the top and doing a lot of stuff. Most likely though all you need to change in the oil seal.

I believe it is called the bull pinion carrier. You are correct about the other stuff.
I would wager if the oring is leaking on the BPC (Bull Pinion Carrier) you could back it out until you feel it hit the bull gear and have enough room to slip an oring on. With all that said, the oil would be leaking down the rearend prob not into the brake area.

The Tractor Vet's procedure is dead nuts on and not nearly as hard as it sounds. The bull gear is heavy and that might cause some problems in getting it lined back up. Having done it once with everything apart I bet I could redo it in a weekend no problem.

My local independant IH repair man says you can change out that big double seal on the BPC w/o taking the BPC out. I tried it and then...well...I don't want to talk about how my BPC broke. Looking back I would guess it could be done. The outer half pried out really easy. The outer cage is really tough, but you could do it. I doubt the guy is making it up. He moves A LOT of tractors through the shop.

I found three extra problems with everything apart so it was all well worth it. After I put new seals in everything it was about $300 plus $250 for some bad bearings and gears and poppet springs. Most seals were from IH, but I should have got them from the bearing shop bc most were half the price of IH.

Well, if I can change out the oil seals in the brakes, Then I might as well find out why my pto leaks also, and what itall take to fix it, and how. Do you think Olsens gaskets would have these seals? I cant find the IH guy up North in Antique Power.

You DO NOT have to remove the bull gears, etc. to replace the brake seals. I takes a little patience and a couple sharp chisels & a hammer. Needle nose vise grip helps. Keep collapsing the old seal inward until it can be pulled out. This is a low less work and teaches you patience (persistance)!
I have replaced these seals on several H's & M's.

I could have just as well wrote this sflem849. That BPC (Bull Pinion Carrier) we wont talk about when I was going to replace my seal. Needless to say I had to go visit the guy with the parts tractors. I am not going to tell you what to do but I had my whole tractor tore down because of the restore and I pulled the main cover to do this change out. I was able to see all my gears and what shape they were in. Good luck
