Another brake question

[Darkroast]

I have a YM2000B

Left brake was stuck. Took it apart and cleaned it up. Lubed cams, shoes in excellent shape. Replaced springs (which were not bad) with new, new gasket and correct replacement cover (Broke the original getting it off). All reinstalled as per the way it came off.

When I lifted the brake operating rod to reattach to the actuater, it was too long. Pushed the pedal down and fastened it in place and the rod still stuck about 2" farther back than the actuating pivot on the cover. How can this be and what did I miss?

Is it possible to install the actuator upside down?

 

[Darkroast]

Yes. The cover will go on in any position and the holes will line up. The Untouched (right) side has the adjuster nut at 12:00 and the actuater lever at 6:00. I reinstalled the left side the same way.

Looking at it, it appears that if I were to rotate the cover one bolt hole counterclockwise to gain the room I need, that the lever would be jammed agaist the axle and therefor inoperable.

Does the 2000b look just like this 2000? Yanmar Tractor Parts: BRAKES

Did you replace the brake rods? I just bought new ones for mine and they are 2" longer than the original and will have to be cut down to work.

Can you post a photo? It would help a lot.

WInston & Gary....

Yes, it looks like the part in the Hoye picture. The rod is the original that was there when I took it apart. I did NOT remove it from the shaft that is actuated by the pedal, just pulled the pin at the clevis end.

I'll take a picture when I go back out to the farm and post it for further advice.

Thanks guys.

Are you saying it is so far out, the adjustment won't compensate? You could/should have reversed the shoes and pivot point which would require a re-adjustment.

I'm sure you seen this link on Garys Brake thread.Since you have the B Series something may be alittle different here is a PDF of a few different versions. Just Let me know and I can get a photo of my 2000A MODEL. Linkage.http://www.fredricksequipment.com/Portals/0/catalog/rear axle and brakes.pdf

I didn't mean rotating the cover. I was asking if you could turn the actuator (cam) 180 degrees and still install it.

 

[Gary Sweat]

You didn't by chance take the clutch rod off at the same time? My clutch rod is 2" longer than the brake rod. (Both on the left side).

 

[careyo63]

Good point.I can easily see how that could be easily done. I do have a pic. of the Linkage that might help to determind if thats the problem.

FWIW here's the best I can do on the R side linkage. May not even be close to your setup.

Gee you guys really came through with help. I'm impressed and thanks to all.

Anyway to answer some of the questions:

The thumbnail pictures are exactly my set up. The linkage rod on the left was disconnected at the brake lever and allowed to hang down (never removed) from the pivot bar that goes to the pedals.

The cams inside, both the adjuster and the actuater, were set straight up and down, for absolute minimum expansion of the shoes (which show no wear) and would not fit inside the drum with any adjustment on either cam.

I don't know if the actuater cam could rotate 180 degrees or what good it would do but will give it a try. It looks to me as if the brake shoes would be in the same position regardless of which flat surface of the came they are bearing against. Maybe I don't hunderstand what you were referring to.

Likewise reversing the shoes. Did I not look carefully enough? I thought they were the same from one side to the other.

As for the rod....yes it is currently situated to far to the rear to connect to the actuater arm even if I use all the adjustment.

I know I am missing something that should be obvious to anyone looking at it.....but ME.

Someone posted a link to Fredericks Equipment. I went over there to get some parts and they have a refurbished 2000B on the lot for sale. Theirs looks just like mine, arrangement wise.......only their paint is shinier and their connecting rod connects while mine hangs down loose.

Ice here last night so I'll wait on going out to the farm till it warms a little.

To avoid confusing ya'll, my membership says SW MO which is correct but right now I'm in Huntsville, AL with the tractor at another property.

The left brake pedal is on a splined shaft that runs across underneath the transmission and has the clutch rod also on it. Check to see if the pedal rod has slipped on the splines (on the right side of the tractor) or if it can be taken off and moved up one or two splines to take out the extra length. This is the only thing I can think of that could be causing the extra length on the left side. Right brake is a different story.

 

[careyo63]

This could be a good one. I had to go check and it looks like it could possibly be done. Did you have both the brake covers off and got them swaped around?????? Just a plausable Guess

Take your camera with you when you go back. I'm all excited just wondering how in the world the same parts won't go back. Got to be something simple. Those are sometimes the hardest things to find.:licking:

That could be. I've gotten several parts lately that were close but had to be modified to get to work. If he's still got the old cover, he can lay them side by side and check for minor differences. My right cover has been welded back together. Caused from a sticking brake shoe and prying on the cover to break it loose.

"Likewise reversing the shoes. Did I not look carefully enough? I thought they were the same from one side to the other."
The shoes are the same, both side to side, and end to end, which is just the point. If worn, they normally wear mostly on 1 end only, and can be reversed for a new surface, but require re-adjustment.

The shoes will usually wear at the bottom more than the top of the shoe due to the cam movement at the bottom. When you reverse the shoes and put the worn end at the top, make sure to adjust the top cam a little to get a more even contact on the shoes. Just be sure to really tighten the top cam lock nut or it will slowly revert back to the center position and you will wind up with slop in the brake pedal again.
