carrier axle swap

[Lynn Eades]

Yes, the back plates can be changed.
I dont know that the crown wheel and pinion can be changed.
The carrier diff has a flanged sleeve that slides into the front of the housing it has two separate back to back timken taper rollers. Most of the the CMP diffs uses a larger diameter one piece double cup with two cones, however one axle housing (f15?) probably works.

As it happens my carrier was originally built with hydraulic brakes.
This involved different back plates and drums made to use CMP brakes.
These were made in 1941. I have 3 sets. I have never seen any others.
I believe they were a bit of a failure.

Marc-The reason I would like hydraulic brakes is to make mine easier to steer. I have done a few "modifications" to my carrier so it only steers with the brakes. It works, but takes a lot of effort to turn. I just thought hydraulic conversion might make life easier.

Using brake shoes only to steer results in a lot of heat and brake fade. Even putting boosters onto the master cyls will not cure the problem. There is a reason why tracked vehicles use steering bands bathed in oil for their steering.

Disc brakes are another matter. If you modify over to those, it will be much more successful.

[B]I have the remains of a carrier that was used for logging. It has had the springs replaced with pipes to keep the tracks on under load & it has hydraulic brakes. The driving position was moved to the rear like a buldozer. This worked well for the logger & eventually made him enough to buy a real skidder.
The down side of brake only steering is that at speed you can easily go out of control, particularly on a smooth surface.

Hay John, mine has this type of set up as well. Its not really what I want in steering but I will be doing a video in the next month when I take the brakes apart on the one side. It will give you a good look at how its put together. I've been told that it was changed to this.

Jack/Shawn-Do you have any photos of the set-up or any idea what wheel cylinders were used? If you are converting yours back to the normal set-up, maybe I could find you an untouched axle and trade you.

John,

The old logging carrier wreck is at my summer home. I will not be there for a while but here is a picture that shows the backing plate & adjuster which looks to be stock carrier. I think the wheel cylinder is a standard truck part & possibly the same as used in CMP axles. It has been a long time since I examined the setup but as I recall the cylinder bolts in to the holes provided for the mechanical activator without major modification. If needed I can take more meaningful pictures the next time I am near the machine.
