I am replacing the steering wheel on my D15. The nut has been left off of the steering wheel shaft and the threads are slightly damaged. I need to run a die on it but don't know the size and thread count. I believe it is a 3/4-24, but not sure. Can anyone help me out on this?

I ran into this once-its an oddball. If I remember right I ordered a die and not from Mcmaster Caar

Get a thread pitch gauge, and use it to measure the threads per inch. Once you know, its easy to look up on Google, what size it is...

we use to clean up  old threads by coating them with valve lapping compound and running a new nut up and down the shaft several times... slowly... little by little.

Thank you all for the information, especially Steve. I did get the nut from Stiener, but couldn't find the specs on it. That's exactly what I needed. I will get the 13/16-20 die and will be back to enjoying my D15. Thanks again everyone and have a great day!!

I think "most" of the steering wheels built after 1960 ( Starting with D series) used this nut.

Had the same problem in 2019 . Think it was self-inflicted , but we won't go there . Have the die in hand , 13/16-20 exactly like Steve shared . Got mine from Brenda at Sandy Lake . Good Luck ! Should say mine was a Series 1 D-15 also .

Had the same issue with my 15 last summer when I changed the wheel. Don't remember exactly what I did but know I wasn't completely happy with the repair, will have to look into a new nut.

Finally got the threads repaired and went to install the new wheel and it doesn't fit. The molded section on the underneath side will not allow the wheel to go on the shaft far enough to install the nut. Has anyone run into this before. Also, does anyone have a parts list view that would show how this all fits together. There also seems to be a clip missing on the shaft that may align the shaft to the proper height.

I think there is a C clip on the steering shaft were it comes through the steering support to hold the shaft up to the proper height. At least my D17 had one, go on AGCO books to view the parts breakdown. It’s been a year ago, hope I’m remembering that correctly.

Stack several machine washers/bushings under the steering wheel and throw the C-clip away. Get the steering wheel so it has 1/4" of up and down movement with the nut tight. Dribble some oil down the steering shaft tube while you're at it.

Thanks for the response! Shimming it up sounds like the way to go, but my real problem is the new steering wheel received from Steiner will not go on the shaft far enough to install the nut. The underside of the wheel won't clear the traction booster lever. It could be the wheel is the incorrect one. I'm sending it back so they can confirm whether it is the right one or not.

Your steering shaft has SUNK down !!! because the C -clip isn't holding it up where it belongs. The stack of washers of the proper height fixes this permanently.      EDIT: Screw on the nut without the steering wheel. Now, pull UP on the shaft and you'll see what I mean. Your steering wheel is fine !!!
