Ball Joint Thread Size?

Tried a search but couldn't find anything...

Does anybody know what the thread pitch and size is for the upper ball joint adjusting sleeve on a 10-bolt? I know it's bigger than 1"-8, but I don't know how much bigger and I don't have an adjuster sleeve on hand to measure.

Thanks.
 
if i recall its pipe thread for the taper to preload the ball joint. but i cant recall 100% as i play with 60s now.
 
I'll measure one..

I think I have an adjusting sleeve in my shop in a junk drawer--I'll try to find it and measure it..I think it does have pipe thread--looks like 3/4" pipe--I'll post back tomorrow if I can find it..:crazy:
 
It's definitely not tapered pipe thread. You can thread it all the way through the axle, if you want to. That's how I got mine out, since the top threads were buggered up.
It preloads the ball joint on the tapered shaft on the ball joint itself.

If one of you could give me an O.D. and TPI on the sleeve, that would be great. :waytogo:

All you had to do was ask. :D

Well, that and I happened to find a spare adjuster while looking for some washers =))

Anyway, looks like ~1.118" OD, ~.800" ID, and if there are six threads in 1/2", I presume that to be 12TPI.

I can mail you the spare if you want it, take pix, whatever.

Awesome. I would assume 1.118" would be 1 1/8" thread diameter and 1 1/8-12 does appear to be a standard size available from McMaster!

1 1/8"-122 9/16"5 7/16" 26035A537 39.51

Thanks, dremu!
Now... to see what I can do to fool my work into buying a $40 tap. :thinking:
 
too late!..

Sorry--I got side tracked over the weekend!:doah: --I did find the sleeve in a junk drawer in my shop last night..but I guess your all set with the dimensions,so I'll toss it back in the drawer I guess...:crazy:
 
If you could verify the diameter and measure the pitch for me with an actual pitch gauge, that would be awesome. :waytogo:

I take it a pitch gauge isn't something used in roofing or baseball? :haha:

I suppose they would use one in roofing but I don't think it would be of much use in this case. :p:

The effort is appreciated! :bow:
 
dremu, I just verified with a pitch gage that it is, in fact, 12 TPI. That's a helluvan eye you got there!

Thanks again. :waytogo:
 
no pitch gauge!..

I don't have a thread pitch gauge!..:doah: --all I have as far as presision measuring tools is a plastic caliper that goes up to 6"!...I don't have much machine shop stuff,only some taps and dies...glad someone else was able to help!..:crazy:
 
A decent tap & die set will come with a thread pitch gauge. That's what I used to check it.
 
not mine!..

I bought a bunch of taps and dies at a swap meet loose,in bins!..so no thread gauge yet!..I do have friends I can borrow one from though...dont have much use for one very often--most bolt sizes I already know what pitch they come in,I do have a tap drill chart that lists all the possibilities..GM seems to use weird size and pitch threads on things like pinion nuts,and tie rod sleeves and ends,and a few other things..and some are a regular size like 5/8,but have a weird pitch on the threads..one AM radio I lacked nuts for were 7/16x28 !..had to have them made at a machine shop,couldn't find any in boneyards!...

:crazy:
 
Got my 1 1/8-12 tap today! :woot:

I need it for this project at work... yeah... at work. :whistle:
