Farmall 140 Front End Steering Box

Postby TractorDog » Sat Aug 03, 2013 4:30 pm

I have restored a few Ford tractors and this is my first IH/Farmall. I got my hands on an Farmall 140 and I am tearing down the steering as it has a 360 degree of play which is insane. The worm shaft looks fine and I sure didn't notice anything too terrible with the bearings. I removed the front axle and am ready to remove the steering arm. The nut on the bottom sure looks like there is a cotter key going through it somewhere. At least the nut is slotted for it. I do not see a cotter key. Does this have a cotter key in it? Secondly, this looks like a nightmare to remove as there is little area to get a wrench on it. Is it me or is this nut easier than it looks? When I remove this nut will there be enough clearance to take the steering arm off the shaft? All I want to do is get the housing removed from the base so I can inspect it.

If you have experience 360 degree play in your steering, what was the problem you found? I am praying it is not the sector which I would guess is costly. I see the rebuild kits are relatively cheap.

Any advise would be greatly appreciated.

It's been a while since I had one apart but I don't recall anything too bad about it. Once you get the nut off the arm there are 6-8 cap screws that hold the base of the steering gear housing on and that's it. I expect a lot of your play is coming from the arm and/or the sector gear slipping on the shaft.

Just rebuilt a 140 front end last month. Yes there should be a cottter key there. The nut can be taken off easy without much trouble.
Mine had a lot of play, which was caused by bad bearings, both of them. replaced them , tightened things up, new seals and now turn the steering wheel and you get action. Just take you time .

Buy the kit, I posted the link on another 140 thread. If the gear is moving on the shaft the keyway is likely worn. Just weld it up, there are thousands of SAs - 140 out there with welded gears in the steering. There is a good chance if you buy a used one it will be welded. By the time you buy a used one and then replace the seals you will have spent more than you would if you repaired what you have, just my opinion.
