H brake drum - fiber washer

Alan Martinson · Oct 4, 2011

Hi. I"m replacing Bull pinion shaft oil seals on a Farmall H. I have oil leaking on to brake bands. My IH dealer has new seals on order for me. I"ve read a lot in this forum about how to remove the old seals - not to remove the housing that holds those seals etc.
I also want to replace the fiber washer that sits under the brake drum retainer washer. If I attached this picture properly, my screwdriver is pointing to it. What"s this washer called and do you have a part #? I don"t see it on the IH parts diagram and without more info. from me, my IH dealer can"t tell me if he has them. Is there another place to get them if IH can"t help me?

I did mine about 1 year ago. I was unable to find the washer, so I made my own from 1/16 gasket material. not that hard to make, you need the gasket material and a small ball pien hammer. Place the material on the brake drum, and use the pien side of the hammer to cut it out. worked well.

Like Tom said, the part is NLA. I just used my old ones. I am not really sure what it does other than give the stuff something to slide on.

Supposed to seal the end of the shaft, so you won't have to clean the oil out of the brake housing agin in a few weeks.

If it isn't torn,I generally re-use it. Put a little silicone or something on it.

The washer seals the end of the shaft. Since the transmission seal runs on the brake drum hub, not the shaft, oil can leak between the shaft and the drum (through the splines) and come out the outside of the drum. The fiber washer is to seal that outside end so oil can't come out that way.

Thanks guys. I'm now in process of making new washer seals as you suggested Tom. Seems like they should work fine.
The IH service mgr. said the same as a few of you: "If you don't have a good seal there, you will get oil leaking around the splines."

I used an old inner tube. Used an appropriate sized hole punch for the bolt, and cut it to fit under the plate. Worked fine for the last 5 yrs.
