Tom,

I don't know anything about LA's- but if you go back and read the response that Tom Railsback gave you when you originally asked the question...

He said that he thought the RESILIENT pulleys off of a later LA with DIFFERENTIAL TURNING BRAKES might interchange with the 500 Diesel.

Full Steam Ahead says that the single foot brake control on the LA was changed to differential brakes in December of '49. It also says that even later LAs had hydraulic brakes (but doesn't specify when they changed again.)

I guess the question is which flavor are you hunting (or were they the same?)

Just wanted to make sure you were asking the guy at Biewer's the "right" question...

Somehow this went from belt pullys to brakes. so here goes on brakes. I owned a 1947 LA and it had mechanical indivual right and left brakes in the wheel. I also owned a 1948 LA (bought new spring of 48) and it had indivual Hydra. (car type master cyld on each petal) in each wheel. The problem I always had was vibriation would always pump up the brakes and they would get hot from draging. I finaly had to drain them and not have brakes as I couldn't keep them working. The defferential brakes were better but not real wheel stoppers. I thought they came with the differential brakes in 51. No LA, 500, 600, 900 or chain drive 930 used Hydra. from the tran. or remote housing for brakes. I don't think the gear drive 930 or 1030 did either. On the belt pulley did you mean by resilient the pulley with rubber pins isolating the flat part of the pulley from the hub???

Yes, that's what I mean concerning the resilent pulley.

I loved the differntial shaft brakes on our LA.
I had an old pull-type road grader and I could
go out of our drive, start to turn the steering wheel, step down on the right brake pedal, and turn the whole unit around in 35 feet. If someone
wants, I can post the serial numbers of the changes in brakes just like I did last night with the belt pulleys.

I just checked both parts books. The resilent pulley in both is 5926A. On the LA's any tractor
after 4904771 had the resilent pulley.
Please note new E mail address if you need to contact me directly. I've not had a phone at home
for the last 15 months and just got reconnected tonight.

Hi Mike,
You mentioned something there that caught my interest. You said that Full Steam Ahead stated the LA went to differential brakes in Dec 49. My 49 LA (sn5320241) has 2 hydraulic brakes.(I'm trying to remove the master cylinder right now). There is also a small removable cover under your right foot so you could add brake fluid. Do you think that was an option or had they switched to hydraulic that early? Could you tell me how I get ahold of a build sheet from Case for this thing so I know what month it was built?
Also, my belt pulley is not a tapered shaft like earlier models(I think they were tapered). It mounts with an adapter that is square with a lobe at each corner kinda like a 4 leaf clover. Really hard to find Don L. says.
Thanks,
Steve Moeller

Hi Steve,

I bet that RobertTX could help you out with your question- he's quite a fan of the LA model. I'm afraid I have to plead ignorance regarding your questions.

Maybe I mis-read Full Steam Ahead? They don't list the changes by the serial number like they do in the other chapters on Flambeau models... I'll re-type the paragraph here and you can see how you interpret it:

From page 250: (Erb and Brumbaugh)

"By August 1948, hydraulics were made available for the LA, although they were only of the remote cylinder configuration. The following month, all Case tractors, including the LA model, were equipped with break-away hydraulic connections.

In December of the FOLLOWING year (emphasis mine), the original L-style single brake with one foot control was replaced with differential brakes to assist in turning. Later LA brakes were of the hydraulic variety."

I read that to be December of 1949. Whether that's "build year" 1949 or 1950 is beyond me.

The link to the info about ordering your build sheet is linked below.

Let us know what you find out.

Mike,
Thanks alot for the info. I think you interpreted that info just right. I really learned alot about LA brakes from this exchange.

The sn info from Tom is also very interesting cause that means my hand brake was an option. I now REALLY appreciate that Dad ordered the hand brake on this tractor cause these hydraulic brakes never did work well for us either:). Thanks again to everybody for the responses.

Hey Steve,

It was interesting, wasn't it? I would have NEVER known from reading Full Steam Ahead that there were that many different braking variations during the LA production run.

These are the kind of posts that make YTMAG (and the YTMAG archives) great. Thanks to the folks who shared their information and history.

Mike,
I had not noticed that about the brakes in the book. My 48 LAs have the hydraulic brakes and I am sure the parts book indicates they were first used in 48. The 48 was the first LA with the high operator's platform, and the hydraulics were designed to work on this platform. As one of the guys noted, the hydraulic brakes are a pain and usually not working. The mechanical differential brakes came out on the 51, I think.
Again, I have not checked parts numbers, but if there are any differences in the resilient belt pulley used on the LAs and 500s, they are not easily noticed. Mine look identical. The earlier bolt on belt pulley is definitely different, requires different hub.

O.K. Here's the scoop on LA brake systems from my
parts book an former dealer gave me 30 yeqars ago this spring:
Transmission foot brake (parking) prior to 5208165
Hand brake--prior to 5208165; it was changed and was still available after that
Mechanical Wheel brakes--prior to 5208165
Hydraulic Brakes--5208165-5418606
Differential Brakes--5418307 to the end of production

OK,Let me see if I've got this right,the belt pulley I'm looking for is the same as some kind of brake pulley thats on an LA brake system?If I'm right then I understand what your trying to tell me,but isn't that going to be just about as bad,trying to find that?But I guess the reason it was mentioned is,it's another option.Well Thanks,I've only seen a picture of an LA,and it wasn't anything to where you could see the brake system. Thanks,Tom

I didn't mean to lead you astray. The belt puuey is completely separate from any type of braking system for the entire tractor.

Thanks Tom,I'm really lost on this whole thing but I'm sure once I see a"LA" I'll understand what your trying to tell me.I really do appreciate any education I can get.I bought a manual but it's too general,doesn't give any details about a "LA".One of those that covers about 10 models(shoulda known better). Thanks Again, Tom

Thanks Mike,I didn't know there was a diffrent type of LA pulley.I just assumed a LA pulley,was a LA pulley.Anyway,I'm still lookin'.Thought maybe you'd come up with one for me(as you say)"grin".How Ya'll Doin' Down Yonder?Pretty cool up here. Thanks,Tom
