carrier axle swap
 

Can an axle assembly out of a CMP be installed on a carrier so that you can have hydraulic brakes? Is the gear ratio similar?

The answer is no. The brake back plates are carrier specific.
The Carrier ratio is 5.83:1 The CMP ratios from the F30 up, are all 7.16:1
The 5.83 diff is also found in the earlier Ford trucks particularly in the british fords with enclosed drive shafts.

Lynn, I know it would be expensive but could in theory that is, could you change the CW+P and the back plates ?

Why?
 

Hi John, why would you want to have hydraulic brakes? Just the axle is no use. You would have to build something in the front to control the brake cilinders too. That has to work is conjunction with the warp steering also. Not easy and in my opininon not worth al the trouble.

Cheers,

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.

I wish my carrier still had the warp steer set up, or at least the steering band brakes. Instead, it is just the standard drum brakes and on pavement at speed, it can get hairy...
