Farmall A Steering gear

Mitch Marschner · Aug 1, 2016

I have a farmall A that i am restoring. I do have a manual but it does not show me how the round steering hub on the front of the tractor
comes apart. I did take the big nut off the front a and the bearing is on the steering wheel shaft i can see do you pull it off any pictured
or advice would be great.

To remove the steering wheel shaft, the steering wheel needs to come off. Then by turning the steering shaft, the entire shaft and bearing will pass out the front of the steering box. Some people have been successful disassembling the steering box while it's on the tractor. It's an upside down job that way. Unless you are young and flexible and are lucky enough to have a tractor that comes apart easily, I think it will pay to remove the steering box and make a bench job out of it. In order to do that though, the radiator has to come off. After that it depends on what kind of front axel you have. No matter which kind, the front end needs to come off the floor. There is a jack-pad at 6 o'clock on the transmission bell housing. All the internal parts are available from Case or after market suppliers, YT is one of them. The Case bushings do not have to be reamed to fit. The aftermarket ones may need to be reamed. The steering worm is welded onto the steering shaft. It is the only wear-part that is not replaceable with new.

Thank you for all of you help. When you say reamed on do you mean pressed on? How do you remove the when they are reamed on.

If the steering box still has the square shaft down through the bottom that the steering arm clamps on, you should consider upgrading to the newer tapered shaft that the steering arm goes on. There used to be a kit to do that but it was discontinued a long time ago. The individual parts are still available tho.

What is the exact problem you are trying to fix ?

CGID · Aug 2, 2016

You may need to ream the I.D. Unless you are set up to do this, the cost of buying tooling or sending the job out will negate the lower price of after market bushings. The problem is you won't know if they fit as is until you buy them. The bushings push/tap out without too much effort.

Reaming means the removal of material from the inside diameter of the bushing to bring it to the correct size to fit the shaft. There are special cutting tools made for this called reamers. Along the lines of a drill, but more precise.
Pressing is a different operation. The reason for a bushing is to take the wear of a moving part. If it were pressed, it would no longer be a moving part.
