We checked the clutch fingers and they where ok, I think the clutch cable is to long, so i will try a shorter one. thanks for the reply.

years ago I had a simular problem when I installed a new clutch and pressure plate in my M38.You need to adjust your clutch fingers to engage correctly.It winds up being page d-3 in my cj2 service manual .Somebody should have it on their pc to share.

Seems to me that the last time I changed my clutch, I had to change the length of the control rod. Not sure why perhaps it was a different clutch manufacturer?

I ran into the same problem when I put the correct trans in my 46.
When purchased, it had a T84 (wrong trans), so the first winter tear down, out went the old, and in went the new T90 (correct trans).
The problem was the transmissions are diffrent lengths, thus the diffrent length clutch rod.

Yes the z bar is in right , to me the throw out bearing is coming out far enough as the return spring is really stretched. To me it looks like the clutch fingers are not close enough, but how can that be?

Is the control tube right-way-around? Short arm to frame side, long arm to transmission side? It can be installed backwards.

Sean-- this was the first thing I looked at, and it was a little off, so I took it back to Walck's and got another one which looks better. thanks for the reply.

Did you all replace the clutch control tube w/a repro?
There is a repro being sold that's manufactured wrong, and doesn't work. Sean |

sudsie i agree with checking the fork for proper install and the possible need for a different adjuster, when I got my basket case there were several different clutch parts with different pitches and lengths and it was a pita to figure what was correct, can't wait to see pics of your finished jeep looked great when I was up to see you a while back

Sudsie- Keep in mind that with your other jeep, the fiberglass tub MAY have a factor in this. If the placement of the floor is diffrent than an original body the pedal and shaft may have a diffrent "starting point" than the stock body. That would in effect change the control rod lenth. If you happen to have had the wrong rod for your first jeep, but it works, then we may be comparing two of the wrong rods. See what I mean? R-

Guys, I also have run into the diffrent lenth clutch control rod issue. I'm just not clear on which vehicle gets what lenth rod. This was the item I need to verify. In the past I've changed many clutches. MB's, CJ2's, 3A's, M38's and A1's. And all related parts. I've fixed them in the field and even made one up out of a piece of chain one time. I just can't get clear which lenth for what jeep. I know we can cure Sudsies problem I just need for my own head to know what is correct. Thanks, R-

Jeff--Ridgerunner & I think this is what we may have to do, but the question is why, since my other jeep has ths same size rod. thanks for the reply . Sid

for what ever reason the clutch rod comes in different lengths. this is the elongated u shaped rod held in with two cotter pins. After I replaced my clutch a few years ago, I ended up having to fabricate a new rod because I could not get the correct adjustment with the old one.
hope this helps

Ridgerunner this is exactly what happened to me before I spotted that the fork was in the wrong place. I did it in a hurry and placed the fork in the grove instead of BEHIND the throwout bearing. After placing it behind the bearing I adjusted the cable back to where it is suppost to be.

I have been working with Sudsie to fix his problem. I have many years working on antique jeeps and this is the first time I've seen this problem. All parts in his clutch system have been replaced and checked against original parts. However, when assembiled together the pedal freeplay, which should be 3/4" is about 2"-3" before the throwout bearing face touches the pressure plate fingers. The clutch control cable is adjusted all the way in! I have a few more things to verify to be sure but this is a strange one. Any thoughts out there? Ridgerunner

It sounds to me that you may have installed your clutch fork wrong. Check it agai, being sure that your clutch fork is behind the throw out bearing and not in the grove of it. UH this is from experience. It fits in the grove so nice, but it will not depress the clutch springs to release the clutch. Let us know what is happening. Ed

I dont have any experience with the specifics on jeep clutches, but they look pretty standard design wise, I would be looking at the clutch arm and the pivot ball, don't know if there are different ones available but I have seen this on GM clutches with all the different arms and pivots that have been made through the years. Looking at the parts manual, it shows 3 different clutch manufacturers, maybe you got an incompatable mix of parts? I'm sure there are others in this forum with vastly more experience than me who can sort this out. Hope this helps somewhat
