Allis Chalmers 312 Steering

Recommended Posts


Hi All,

The piece where the steering plate (see diagram from manual below) connects to the bottom tractor as broken off and lost in a field somewhere. I am going to machine a new part but cant seem to find an image that shows what the original part looks like and how was connected. I assume it is just a metal rod that acts as a rotation point for the bearing sleeve.

Has anyone encountered similar problem with their AC tractor?

I can include more pictures later today.

The steering on your tractor is unique to the AC 300/400 tractors I believe; it's very different from other steering setups.  Hopefully a AC 300/400 owner that has experience with the steering parts will help you out.

I ended up finding the original broken part. Looks like the previous owner had the same issue and welded it back on. Girlfriends dad machined me up a new part that he drilled and tapped and I just bolted it back on. Good as new. 

I'm still curious to know how it originally was attached if any 312 owners on here see this.

Glad to hear you found the missing part and have it back together.

And every old iron user's significant other's Dad should be a machinist!  He did did some nice work for you.

I believe I'd put a grease fitting in that sleeve, if doesn't have one.  Could it be that was the cause of the original failure? New part sure looks good.

Great idea.

I'm sure "Dad" could do it easy.

      Hello glad I got on this site. I hope to upload a couple of photos of my Simplicity Broadmoor 
      Model 707 Tractor. I have replaced all the belts on it and installed a new ignition switch.
      Have a mower deck which was in poor shape , repaced a couple of bushings and welded the
      deck where there was some holes. The tractor and mower deck came from a friend and the 
      mower deck metal was getting pretty thin. Some new metal was put in it and we also undercoated the underside of the deck. This was done by my friend Greg Toulman.
      I have not put the mower deck on the tractor yet, waiting for Greg to come home and give me a hand. Can you please tell me if there is a manual for the mower deck and where I could get one.
      I would also like to get some moon wheel discs as well.
      I will try and down load some photos of the tractor when my wife shows me how to. 
      I really love driving this tractor and also how well it is made compare today's tractors, especially the flexible rear end and the rollers.
      Tell the next time
