could some please explain how the internal brake works on my 126. thanks in advance

Your 126 should have an external brake setup on it. Does it not have the brake discs on each rear axle? If not an internal brake setup has a disk on the front of the transmission output shaft. There is a "puck" that is actuated by a lever on the front of the transmission gear reduction housing that applies the stopping force to the disk thereby stopping the tractor.

Here is a cutaway of an internal brake tranny.

no i think the trans was swapped out cause its the internal set up and i was told today be a friend that the rear tin is off a diff tractor. the brake adjusting screw does not reach the pin when the brake is applied so do i get a new bolt?

[IHCubGuy]

I would check first off if it can just be readjusted. Make sure the piece that pushes on the lining (which sits between the lining and the actuater) is not frozen. From there see if it can be adjusted by the screw on the actuating lever or if it is missing pieces even. If none of this helps it may be that the adjuster screw is broken off or is too short for whatever reason. Hope this helps.

im missing the piece after the adjusting screw. i turned the screw all the way in yesterday and that when i noticed something wasnt right thanks for the help. also what size tires ahould i have on the front of the cub i dont think mine are the correct ones. thanks

They should be 16-6.50-8. Some people like the narrower 4.80-8 though; which is the same height just narrower.

It may be missing the Pivot ball.It looks like a ball bearing.
You won't be able to adjust it close enough for the brake to engage with it missing.

I had my 102 all apart to replace the gaskets and seals and lost mine.It took a while to figure out why I couldn't adjust it enough for the brake to work.

Here this will help a bit.

4.800x8 4.00x8 or 16x6.50x8 front tires

Narrow tires was an option on most of the late 60s-mid 70s cub cadet tractors.

I like the narrow tires because they are Alot easier to turn.I've had both the wide and narrow tires.And for plowing or blowing or towing they seem to work the best.

The narrow tires will leave small ruts in softer soils though while turning.


My new to me Cub 149 has the narrow tires I really like them.

the pivot ball is there but the adjusting screw still does not come close enough with the screw all the way in. thanks for the tire info as my front tires are diferent sizes with different rims.

Some one may have replaced the bolt and Jam nut?

I can't tell you how long the bolt is.I gave my 102 to my uncle and got a 149,it has external brakes.

im missing the push rod betweent the piviot ball and adjusting screw. how do i find out what year or model my trans came from?
or is there a number on the frame that i would be able to use to indicate what year it is as well if it is a true 126

If the transmission was replaced the exact year of the 126 will be hard to determine as the serial tag is on the back of the transmission on them. Some other models had them on the back of the transmission as well. If there is no tag on the back side of the transmission then look on the side of the tranny on the right side as you would be sitting on it. The number will be punched in to the side there. Once you have that number we can track what year the tranny was made and determine the models it could have been used in. As far as a 126 goes they were made from August of 69 to August of 71.

As for the rod, the part number you need is IH-384721-R1. I would say go thru the used parts vendors to obtain one. Just tell them you need one off of a 70 or 100.
