Farmall Super M Steering

Looking for help in repairing the steering on my Farmall Super M (?). The question mark is because I don"t know for sure all the "facts" of my tractor.

Was using the tractor to push snow and the steering linkage broke inside of the front housing. My manual does not have repair section on the steering. Any help is welcome.

Take off the hood & grille. Take off the steering sector cover. Look inside and see what is wrong or broken and let us know.

Andy,
Thanks for the reply. When going into "unknown" repair territory I like to get some insight first.

It will be Monday before I get back to the repair, but I will "post" what I find.

follow andys advice on accessing the steering gears. after you get the cover off, you will see a large round sector gear with a nut in the center. to the side of it you will see a smaller worm gear that is part of the lower shaft coming from the steering wheel. that is a tough set of gears in there, not sure what broke, so take a good look. it may have sheared the roll pin up near the oil pressure and temp gauge if you are lucky. to remove the worm gear, there is a pipe cap at the end of the bolster, unscrew that, then drive the roll pin out up near the gauges, the shaft will then "unscrew out" thru the hole where the pipe cap goes.

Glenn,
Thanks for the detailed "walk-through".

Do I remember right---that there is a woodruf key in the steering shaft by the knuckle up by the oil pressure/ water temp gage?? I believe it is held tight by a 3/8 bolt. Worth a look.

Thanks again for the added info.

Finally got back to my Super M.

The steering "down-shaft that holds the sprocket that is turned by the upper worm gear is broken in two.

What is "next" on the repair? How to get the shaft out of the housing?

Has anyone purchased either of the below repair manuals?

Super M Service Manual 170 Pages (Part No: IH-S-SUPMTA,W6)

Super M I&T Aftermarket Shop Repair Manual 88 Pages (Part No: IH-8)

I will buy both if the have good info in each.

Dick, the repair manuals aren't going to give you a step by step "Time Life How To" unfortunately. Better than nothing, but you need to be able to identify how things come apart.

So you're saying the vertical shaft is broken, right? That's pretty common as the shaft is what supports the front end on tractors with the narrow "tricycle" front ends, and takes all the stress from the bumps and bounces. It comes out the bottom, which means you have to remove the front wheels.

This is best done on a solid level concrete floor. Jack up the tractor and support it with cribbing, or better yet a set of splitting stands, behind the front wheels. The front wheels will likely stay on the ground because the shaft is broken.

Remove the four bolts that hold the front pedestal on to the shaft. Roll the front pedestal and wheels out of the way. The broken half of the shaft will probably fall out on to the floor at this point.

Up on top, loosen the universal joint clamping the front steering shaft. Remove the plug on the front of the steering gearbox. Turn the steering wheel to the right to screw the worm gear out the front of the gearbox. The front shaft and worm gear all come out at once.

Remove the cotter pin and castle nut off the top of the sector gear. The other half of the shaft will probably fall out on the floor now too. IF not, give it a gentle tap and it should fall out.

Go to a salvage yard, get a good used shaft, and reverse the process to reinstall it. It's a good idea to replace the top and bottom bushings, as well as any seals, in the steering housing while you've got it apart.

Thanks for the "step-by-step". It is very helpful.

To all that helped with my repair job; thanks. Found a steering shaft at a local shop and I'm back in the tractor seat.
