Brakes: toggle or non-toggle

[CaperKen]

My 1948 Cub has the toggle-type brakes, now removed for refitting. However, someone told me that the toggle brakes were not produced until some time later than 1948. I need to make the best of what I have.

My question is whether the non-toggle type brakes can be fit to the toggle-type brake housing?

Housings are different. Get a part number or cast code off the current housing to see what you have.

The final for the toggle brake has a much wider opening than the non-toggle. I'm pretty sure you can go the direction you want to, but not the other way.

Hi,
IH changed to the newer brakes during 1953, at Cub serial number 173601.
The newer final drive castings have bigger holes in them, where the brake rods go into them.
If you have a 1948 Cub with the newer castings, and brakes, someone has replaced the final drives with newer ones.

If the newer style of brakes were there, you could use the same style.

Below are pages from the Cub and LoBoy parts manual showing the brakes.

Below are pics from TM Tractor of the 2 different final drives.
The 1st pic is the 1st style of brake.
The 2nd pic is the newer style of brake.

I guess Bob posted while I was writing this.

Judging by the pics Glen posted, I don’t think the attached brake rod would clear. If you currently have toggle brakes (on both sides) you should be thanking whoever changed them in the past, they are a much better design.

Could you modify the castings ,by grinding a larger opening, to fit the later brakes? Would it be worth the better brakes?

[CaperKen]

Thanks, everybody. I have the casting with the larger opening for the toggle brakes. Some PO must have swapped final drives on this tractor.

I did not realize that the toggle brakes are a better design. That's good to know.

Those photos are very helpful.

I would think you could probably remove some material to make the toggle brakes fit, but doing so would certainly weaken the final drive somewhat. Whether or not that matters, I do not know. I am not sure if the casting for the final with the toggle brakes thickened up the housing to compensate for the wider slot.

Without a good look at the tractor, it is hard to tell. However, I think it is more likely that a later tractor had the front bolster and serial plate from a '48 installed, rather than a '48 had 2 later final drives installed.

What is the engine number? How about date codes from the engine block, bell housing, or transmission case?

I tend to agree with Jim. I blew up Ken's avatar the best I could and to me it looks like it might have a four bar grill. Hard to tell if the hood has the ripples on the side.

. . . I blew up Ken's avatar the best I could and . . .

When I tried that, I wondered if it maybe had a short-eared instrument panel. But it was too blurry to really tell anything.

Jim Becker's idea to check the casting codes might help sort it out.

Hi,
They fit normally on the Cub we had.
Look at the positions of the brake pins in the 2 pics, and compare them, the newer casting looks like it has a little more room above and below where the brake rod would go, if both castings had the 1st style of brake band in them.
Look at the positions of the holes for the bolts that hold the castings on the Cub, the hole above the brake rod, and the hole below the brake rod.
There is a bigger area open on the newer casting. They removed metal and made the hole wider up and down. My opinion.

There is an engine serial number, it is stamped on the left side of the engine.
Below is a page from the 1949 Cub owner's manual, showing where the engine serial number is, you may need to clean it to see it. It is not the same as the tractor serial number, except on the first Cubs, in 1947.

There are casting date codes on the larger castings on Cubs. They tell the date when the parts were made. They use a letter for the year.
Below is info from TM Tractor showing what the codes are.

The info below shows where the codes are.
The code on the clutch housing is usually partly behind the clutch pedal.
The code on the last part on the page, the steering gear housing, usually can't be seen with the tractor assembled.

Like you fellas, I enlarged the avatar, as much as I could, it kinda looks like a short dash but too blurry to really tell. Might be a Frankentractor. A few casting codes should tell the story. At any rate, it has toggle brakes and I sure wouldn’t give them up.

Hi,
There should be a dowel pin at the top and bottom of the surface where the final drive attaches to the Cub. If any are gone, TM Tractor has new dowel pins, below is the listing, it has pics of where the dowels are. There are dowel pins at the right end of the right side extension also.

When putting a final drive on a Cub, be sure the brake pin goes into the holes in the castings, at both ends. It can break the casting to tighten the 6 bolts holding the final drive on, if the brake pin is not in the holes.

Below is a pic of putting the right side final drive on, and the brake pin in the hole.
