H brake leak

I am getting a drip from one of the brake housings on my H, how many seals are there to leak there?
 
I replaced that seal once, would assume there is wear on the shaft.

Can I double seal it?
 
the original seals were a leather seal that were wider than these neoprene seals of today , might be possible.
 
Thanks,

There is a local parade this upcoming weekend, will pull off after that and before next hay crop.
 
Yes, you can install two thin modern seals in place of the original thick seal. Pack some grease between the lips of the new seals, this may help prevent leaks.
 
The bull pinion seals are a double set of seals. You have more than enough room to put in two new seals. I highly recommend doubling these seals. If these are still the original leather seals, you can bet the seals have worn the shaft. You can position the replacements seals to hit a new part of the shaft. Make sure you get double lip seals when you buy them. This discussion is the easy part. Getting the old seals out can be a real chore. The factory seals are two seals enclosed in another sheet metal carrier. Usually you get the seals out, but the outer carrier will still be left in the housing. I use an automotive seal puller, small chisels, vice grips and what else I can get into the housing to pull these out. If you can pull the wheel off, it makes it a little easier. It's not required, it just gives you more access.
 
The replacement seals are likely to be thinner in thickness. Some put two seals in the same bore. Doing that is good and likely to miss the groove. Pull the seals out of the carrier with deck screws and a slide hammer. Put a good pack of grease between the two seals to prevent the outer one from running dry over its lifespan. Jim
 
(quoted from post at 11:14:23 07/04/15) There ain't NO WAY you are going to drive a new seal in. The factory seal fills the entire space.

The original poster previously stated that he has already replaced that seal once, so he CAN drive that seal further in and install a second one.
 
Original seals were by Chicago Rawhide, becusae of the Chicago stockyards. Thick and beefy. New ones are thinner, and rubber of some sort. I found that the thin metal shell of the new ones bends easy, I finally found a piece of schedule 40 PVC [ as I remember ] that I used as a sleeve to tap them in place. Worked great. 3-inch or 4-inch or so, you can measure it and see. Perfect fit. I think the open U side aims IN, so it fills with oil.
 
Yes, about 3 years old, tractor is finally getting worked enough to find the weak places.
