Not sure of the size. But when I pulled mine, I just used an oversized crescent wrench.
Then beat the handle of the wrench with a hammer... came right off.

maybe someone else knows the exact size? (bump.)

 

my 83 CJ7 is 1 1/8"

 

Every one I've done is 1 5/16",

 

x's 2 here.

 

thanks, 1 5/16 it was.

 

So, what did I win? :2thumbsup:

 

Bump... does anyone know of a good source to actually replace the pitman nut???

Mine is toasted and needs replaced.

It is probably a 7/8-14 jam nut, try fastenal

 

Okay, dumb question, but could a new steering gear box have a different size than a 7/8-14?

I got a re-manufactured Cardone 27-6534 gear box, and new 7/8-14 nut will not go on it. I went back to the local auto store where I bought it, asked them, they pulled one from the shelf, tried a 7/8-14 and it would not work.

Ive looked online, no luck.

The threads look good, all thought I may have rolled the first thread trying to get the nut on, no more than 1/2 a turn.

The diameter of the shaft is .860, which leads me to think its a M22.
Thread count is 14 per inch.

Any suggestions?

Thanks
Mike

 

Don't now for sure, but Saginaw did change to metric threads for the hose fittings in 1980, so you may be right about the M22 size on the pitman nut.

 

I was able to get it fixed....by filing off the first thread to get to clean straight ones.


I also got this information from the Tech email for Cardone

Here are the specs I have available..............

Good info, thanks for posting!

The buggered threads can sometimes be chased with a thread file. I carry one on the trails for all those 40yr old bolts we mess with. LOL
