adjusting new brakes on 48 H

Farmallb · Jul 10, 2010

Ive got the whole thing installed, and ive adjusted the adjustment spring/yoke all the wqay in, and all the way out. It makes no difference, the brakes wont tighten. I know ive got the band in right, as I bought 2 covers, and the guy sold them to me with the bands still inside. I made sure when I took out the old band to look at it, and to put the new one in the same way with the toggle being with the humo outward, and the flat inward. I , when I had the band installed looked again to make sure they both looked the same. What aam I doing wrong. The arm at attaches to the brake shaft is set in the keyway, and fastened down. Ive broke alla the strings to my fiddle. Any ideas.

If you shorten the link as short as it will go and you can't get tension on brake band something is assembled wrong. Can you get tension on band by just pushing down on lever with link unhooked. Normally the lever will be close to parallel with tractor frame when released.

I agree that the lever should run paralell to the bottom of the floorboard, but it dosent It runs up to the bottom of the floorboard. Yes, I can get tension when it is unhooked from the pedal, but the pedal applys way more torque than what I can that, tho I think I have tension by moveing the lever by hand, when I attach it to the pedal, and apply a little tension/push on the pedal, it goes right and all the way down. I suspect that theres something to do with the square headed bolt at the bottom of the cover, tho I dont know what it is. I have I & Ts manual on it, and it says to tighten the bolt all the way tight, and then to loosen it 1/2 to 1 turn till all drag is gone. Whats drag, in something that isnt moveing? the band at the very bottom of the drum isnt moveing to create any drag, so thats got me all lost.

The bolt pushes the band against the drum, you back it off until the drum does not drag against the band. As Pete said you have something assembled wrong, provided the guy sold you the correct bands. Some of the aftermarket ones don't fit right.

Like CNKS said, the aftermarket brake bands are too long. I forget, they are something like 3/16 or 5/16" too long. The only way to fix them is to cut them off, overlap, and reweld them.

Worse, if you actually use the brakes, the spot welded eye will evetually pull apart. Usually that happens when you really need them to turn short.

Drill through the spot welds one at a time and weld them up too. I went so far as to weld along the edge of the folded over piece. That held until the 'eye' ripped out...

Do you still have the old, original bands ? They have a seperate heavy eye rivited to the top end of the band. If you measure them you will get the correct length.

If you do have the originals, and want to sell them, I'm interested.

I put my new relined bandover the old one. They seemed to be the same size. Im not saying the band itself is new. Im saying the liner I put on it is new.
