La Case

[Ochs n]

Had brake pads on a LA Case tractor recovered, when I went to install break drum, brake pads were too thick by 1/8. Pads were 3/8 thick. Haven't found any info on how thick these pads should be from what factory sent out. Anybody have some info on this?

I'm going to jump into the fire here, and give you my view on this. You say the pads are too thick where the drum will not fit. I am using my experience on the Racine 400 Case tractor to explain myself. Orientation of the bolt holes on the the drum{cover} must be in a specific place. You have stops where the linkage must fit into, and if you do not hold your Tongue just right, the drum will not mate. Did you replace seals on the differential shaft ,and press them in far enough. Linkage must be able must open laterally to allow for proper fit. I hope this has not confused you. Other may make this clearer. I have a pic. of the mating, of the drum cover, but can not find it right now CM

I replaced the seals on the axels. I had all the brakes adjusted back as far as they would go. I didn't have the drum in far enough to get tight on the axel. I could move the 300-pound drum around, but it would not go over brake. It was like it was 1/8too big. The axel is tapered, so the farther it moves in the tighter it gets on axel. A brake guy found the Case brake pad dimensions and the pads are too thick.

I am going to research the SEARCH tab in the Modern mode , and see what older posts have to say about LA Brakes.CM

I had the shoes relined on one of my LA's and had the same problem.
I had to take a big wood rasp and cut the linings down to let the brake drum go on.
Took a lot of work, but it worked.

I appreciate your time guy. I barley remember that there was some thickness difference on this case tractor. Couldn't find any info in my tractor books, all they had was part numbers. I think will have to look into finding Case drawings from factory to tell demotions off brake pads.

50 years ago when I was in auto mechanics school we had a machine that rearced the shoes on drum brakes to get better contact to the drums after they were turned. If you can find a brake shop with one in might make the job easier.

I spoke with a gentleman in Sturgeon Bay Wi. tonight , and as he recollects, the liner material should be .250 1/4 inch thick. 3/8 thick material seems to be a little bit of over kill. That is my advice to you. Keep us updated on your progress. That is quite an inspiring project you have started. Chuck Machinist

You must have the shoes inside the rear wheel. They are an s o b to work on. My 42 LA has trans. brake only. Cost me $16 bucks for a new lining off the web. Stops on a dime...one reason I wanted an older one. Of course it doesn't have turning brakes though...

This is really a small part off what I have done to this tractor. Drained the transmission rear end oil to put in some new clean oil. When oil all ran out I stuck a magnet in on oil drain and came out with a ton off metal. Started to tear bearing out to see where damage was. Didn't find any real bad bearings. Tock transmission and rear end all apart and cleaned up everything. The only place I could think there was a bearing out was the planetary gear shaft. Replaced some bearings and races. John Saeli helped me a lot. Have it all back together except for brake pads. That has been a learning experience for me. Hope to be able to get this thing running this spring.

My first LA had a straight pipe like that and you could almost plow at night because the flame was so bright.

If the shoes are wrong, they are wrong. Really know nothing about the brakes on an LA, does the drum have a lip on the edge from wear like auto drum brakes get? If so grind that off with a 4 inch angle grinder. An 1/8 inch is a lot, but 60 or 80 grit sandpaper on a regular electric vibrating wood sander will take it down pretty quick. If these are newer replacement pads they should not have asbestos in them, but do it outside and wear a mask a keep the work down wind.
