dave69vert 10 Report post Posted March 26, 2011 I'm working on my 69 and I'm having trouble with the P/S control valve to pitman arm stud. I measured the tappered stud and the pitman arm hole, the stud is larger than the hole by just enough that you cant use a cotter pin to lock the stud in place. I checked the casting on the pitman arm and the numbers are correct for a 69 P/S arm with a 1 1/8" shaft. I have looked in CJ'S pony parts catalog and found they make only one size ball stud for 64-70 control valves. Anyone out there ever seen or heard of this problem.:surrender::hang: Quote Share this post Link to post Share on other sites
LoneWolf2U 136 Report post Posted March 26, 2011 Yes, the 68 I just rebuilt had the same problem. I use one of my porting stone to clean out the pitman arm hole slightly so the cotterpin could be installed after torking the castlenut down. Quote Share this post Link to post Share on other sites
dave69vert 10 Report post Posted March 26, 2011 I just found a 65 control valve and my pitman slide all the way down the stud with no problems. I got this one on my 69 rebuilt on ebay, now I know why it doesn't fit. I thought I was loosing my mind. I guess they do make 2 differant type of studs then. I guess I'll have to get a new stud kit from cj's and try that. I really don't want to redrill or grind that arm. Thanks Mach1Rider for getting back to me.

LindenBruce 27 Report post Posted March 27, 2011 YES!! I have the same problem and since my car is not on the road yet I haven't gotten around to figuring out a solution. I bought a new control valve late last summer and the castle nut will not run down far enough to install the cotter pin. I know I have the right pitman arm so I am baffled as well. I did find a reamer just for enlarging the tapered hole in a pitman arm, but I have not yet bought it to make the fix. I too thought I was going nuts. Maybe someone will chime in with some answers.

LoneWolf2U 136 Report post Posted March 27, 2011 I didn't have to ream out the hole, But mearly clean the edge on the top opening under the castlenut. Seems that it had a slight burr holding the stud from coming all the way thru. Quote Share this post Link to post Share on other sites
dave69vert 10 Report post Posted March 29, 2011 I called CJpony parts and ordered a rebuild kit for it. I didn't want to modify the hole, cause if the control valve goes bad and I have to get another one it might be the right size and then I would have slop in the steering. We all might of purchased from the same guy on ebay. The studs might be from china. I hope this helps you. Quote Share this post Link to post Share on other sites
LindenBruce 27 Report post Posted March 29, 2011 Do you have the measurements off of your original stud at the top and bottom? I may have to do the same thing and buy a stud kit. A real bummer for a part that was supposed to be brand new to begin with. Bruce Quote Share this post Link to post Share on other sites
dave69vert 10 Report post Posted March 29, 2011 Give me to the weekend to get back to you. I just recieved the rebuild kit from CJ's today. I'm shot from workin. I have 3 differant ones to measure now. One from a 65 (I think) the one thats wrong and the one from CJ's. The 65 fit perfect, I hope CJ's does too.

dave69vert 10 Report post Posted April 1, 2011 Ok, I have it apart. Just looking at them both you can see they are differant. The correct on goes from .575 to .625 inches on my micrometer. The wrong one goes from .600 to .650 on the meter. The correct one's shaft tapers then goes straight, while the incorrect one tapers to .650 the tapers back smaller then .600 . The ball socket looks the same, and it wouldn't even matter do to it has it own matching seat. I found an excellent exploded view of it broken down in steps on ( stangersSite.com). This will help you take it apart and put it back together the right way. I'm still crossing my fingers that I rebuilt it correctly. Take your time and be careful not to damage any parts. I hope this helps you. Dave Quote Share this post Link to post Share on other sites
LindenBruce 27 Report post Posted April 1, 2011 Excellent Dave thanks!!! Now I will measure mine and I'm sure it's got the wrong stud. Bruce Quote Share this post Link to post Share on other sites
