Farmall H -Brake cover, shaft, brake drum seals

AL Moyer · Jul 24, 2011

Posted back in the begining of June about cover removal, got the cover off, but separated bushing from the cover as it was rusted to the shaft, & then got the shaft out of main block. Not sure if the shaft & brake band mechanism is savageable or not, are these available new ? Also, looking for the drum shaft seals, seem that the replacement ones aren"t as deep/thickness as I see mention of installing 2. Anyone know a part # of these seals, I have a bearing,seals & drives supply store near by. I"m sure I"m not going to get the seal out without destroying it, & I don"t beleive taking off the bearing plate retainer (?) off to tap the old seal out is a good idea. Thank, Alan

You can get the brake band new on this site and the seals you should be able to get new at the pace by your house. You can look up diagrams and part numbers on CaseIH.com. The new seals will probly be thinner because they use some kind of rubber instead of leather or whatever they made the originals out of.

Do a search for brake drum oil seals & you will find many suggestions.
My suggestion: It is not easy to remove the old seal but patience will help. Do not try to remove the cast iron seal retainer; it will break unless the bull gear is removed first.
Be sure to get all the old seal removed; it is about 3/4" thick & has an outer liner holding everything together.
Replace with 2 (two) new style seals and put some chassis grease in between them for long term lubrication protection.
Use steel wool to clean the brake drum sealing surface making sure all scratches are removed.
Lube the brake shoe pivot bushing before you slide the new linings in place.
To adjust the set screw on the bottom of the brake cover, apply the brake firmly locking it in place. Now loosen the lock nut and turn the set screw in until snug; back out 1/2 turn and relock the nut.
Repeat for the other side and adjust the pedals for equal braking effort so when the pedals are locked together the tractor stops without pulling to one side.

I just went through this same exercise about 6 months ago. NAPA has the seals, and I used just one, but 2 certainly doesn't hurt anything. Look for the seal number on the CIH web site. Then go to the NAPA online site, and in the upper right hand corner, there is a cross-over link. Enter the CIH number, and it will return the NAPA number.

I used anti-seeze on the brake pivot axle. Use battery terminal felt washers for the dust seal on the brake pivot axle.

Lastly, if your brake bands still have decent life in them, but are oil soaked, use a propane soldering torch to "cook" off the oil. Don't get them too hot. Final rinse with brake-clean, and scuff the surface with 100 grit sand paper.

I did check the CIH site, however not sure which seal # because it list 2 seals & 1 oil seal. The place that I would get the seals from is a business that sells bearings, drives, seals, & belts, Not a NAPA store. I have new brake bands to install, but the shaft assembly is pretty rusted up, so I'm thinking it might be better to replace.Also, there was a leather(?)seal/washer on the end of the brake drum splined shaft ?On another note, what's the best shop/repair manual for these Farmall H's ? thanks

Joe's Farmalls will have new parts or Burgh implement will have good used brake parts. There is a gasket that goes on the end of the brake drum, that I just cut one out of gasket material and made my own.

Seal number for the brake pinion shaft is: 358777R91 or 48498D or 358777R91 (any one of the 3 will work, they are just different part numbers)
