    Posted: 26 May 2011 at 1:21pm
What size tap and die do I need for the steering wheel nut on a '60 D14 with power steering? I boogered up the threads on the neighbors from smacking it with a hammer. I had the nut on but everything was froze so bad I hit it hard enough to mess it up anyway. Its enough that I cant get it started now. Thanks for any help.

You won't be able to start a die to match the threads if you have mushroomed the end of the shaft. A thread file will let you match the threads. My wild guess is that the threads are 20 or 24 pitch. Thread files come with 8 pitches per file so it only takes a couple to fit most US threads. You can get there with a small triangular file but it takes a lot longer and a great deal of skill to make a good thread again.

I didn't mushroom the end of the shaft. I had the nut on the shaft. I hit it so hard I messed up the first threads on the nut and shaft(I hit it in the wrong spot while beating and made the nut go sideways on the shaft).

I need to know the correct pitch before I go to the store to get the tap and die. Thanks.

A tap cuts internal threads. A die cuts external. You only need a tap, prob be cheaper and less trouble to buy the nut.

I need a tap and die. It messed up both. I might would be able to get a new nut to start though. Where would I get the nut without ordering it? Its not very tall.

Measure off 1/4 inch of full threads on the shaft and count the number of threads in it. Multiply that number by 4 and you'll know how many per inch. If ya don't have a lathe any machine shop could find or make ya one the right width.

As far as the shaft thread. Do the file thing. You'll get more use out of it then that particular size die.

I messed the shaft up on my 14, so I took another nut, cut it in half, sandwiched it around the shaft , held it together with a pair of vise grips then turned it off.

Measure the thread dia of the shaft then pick the NF (national Fine) thread for that dia. Then you have it.

Like Gerald said, a die would probably not do you any good. If the first thread is messed up, and you get the die started it might not start at the same point the original thread started. If the die doesn't start at the same point the original thread started, you will have a mess of unusable bumps on the end of your shaft.

Nuts we have in stock,they are 13/16-20 UNEF and cost $5.00
If you are going to replace the steering wheel anyways do all your hammer work and bust off all the rubber/plastic the head with torch and drive off hub. you can hacksaw off 1/8" of the damaged threads (No more than that) and clean up the threads with a thread file or a diamond file one thread at a time.

There are thread chasers made for that that work the same way but your way is much cheaper. May not be as hard of material but if it works it works.

I had the steering wheel off already. We did tear up the old steering wheel getting it off(he ordered a new one anyway) I had everything apart to paint and had to beat on the shaft to get the u-joints back on and a new pin through them.

I'm gonna see if any parts store loans tools so I can rent a tap and die.

They aren't going to have that size tap and die. Look at McMaster-Carr www.mcmaster.com and be seated firmly when you find the price. 13/16 isn't a standard diameter and 20 pitch isn't a common standard thread except for spindle nuts. And the die won't work on the bashed threads and a nut is much cheaper than a tap to clean up the nut you have.

If the new nut don't work I guess I have to buy a new shaft which is going to set me back. I'm not getting paid enough for this job as it is.

The D10 is 13/16-20.  I ordered the die from Snapon Tools online for less that $12 including shipping.
