All,I've rebuilt tranny and transfer case and reinstalled in the chassis. I got new clutch control lever and tube, clutch pedal release rod, clutch and brake pedal shaft, and clutch control cable installed (all purchased from Walck's). I am using the old clutch and brake pedal shafts and the clutch control cable adjusting yoke. With all the clutch linkage parts installed per official Willys manuals, I find the clutch control cable and adjusting yoke lays against the transmission case when clutch pedal is in the "up" position. Is this normal? It doesn't seem like the cable or yoke should be resting or rubbing on the case, but I can see old wear marks in the case suggesting this was happening in the past. Adjusting the cable tension doesn't change this situation, but it seems like a shorter clutch pedal release rod would. Thoughts?
Also, the clutch retracting spring running from the clutch pedal shaft to chassis seems to rub on the body mount bracket when pedal is depressed. I don't recall this happening with the old linkage parts, nor do I see any evidence of past wear on the chassis bracket. Any thoughts on what is wrong with my setup? I'm ready to drop in the rebuilt engine, but want these clutch issues resolved before I do that. I will try to get some photos to illustrate the issues, but am away from the jeep right now. Thanks.

Did you by chance install the cross shaft that the cable a clutch rod hook to backwards?The side with the internal spring goes against the transmission. John

Oilleaker1,
Yes, the shaft is installed correctly, with spring towards the ball stud on the transmission.

Steve, never seen this problem. When you get pictures, I'll take a look and try and help, John

As promised, the photos of my clutch linkage issues:
Here is an overview. Note how the clutch control cable and adjusting yoke rest on the transmission casing. You can also see how the clutch retracting spring rubs on the body mount flange. FYI, in this and subsequent photos the "original" clutch control cable is used. It is just a bit shorter than the Walck's replacement. Also the brake pedal return spring is an old one just to hold the pedal shaft up. A closer view. The locking nut on the cable is resting directly on the case. The new clutch control cable from Walck's is partially visible laying on the jeep frame. So, do I have a problem here, and if so, what's wrong? p.s., sorry about the photos being upside down. They were oriented correctly on my iPhone and on my computer! Edited by sibaropsis - 04 Apr. 2015 at 6:59pm |

The clutch pedal has no body floor to stop it from rotating rearwards. I see nothing wrong. The arm next to the tranny will be standing straight up when the end of the clutch lever stops at the floor hole. Then: a washer spring and pad with the shaft of the pedal installs into your arm. John

Several questions: What is the measured length of the clutch solid rod with the two 90 degree ends, and is the moon key installed in the cross-pedal shaft, that the clutch pedal arm locates onto? The brake pedal arm is free to rotate on the shaft, but the clutch arm is keyed solid to the shaft. looks like it isn't in the picture. Another question, is the clutch release cable that goes into the bell housing seated in the cup of the clutch release fork? It looks like it is either too short, or the cable is forward or farther in past the clutch fork. John

John,
The solid clutch rod measures 10.75" center to center on the holes. My old one looked like a homemade version using a yoke and clevis pin at the back end, but same length. The clutch pedal arm does have a key installed. With the clutch return spring fully retracted, the keyway is at about the 1:00 position. What position is that keyway in when the clutch pedal shaft is hitting the tub floor/firewall? Do I have to wait until the tub is on to adjust the clutch control cable? Also, thanks Rocketeer for flipping the pictures! |

My adjustable rod, that has two clevices instead of two 90's is 10 3/8 center to center, and the key is just shy of 12 o'clock when the pedal is stopped against the floor. Yes, you adjust the pedal for freeplay after the tub is on. Should have about 1/2 inch freeplay, and the clutch fork should not be riding the throw out bearing against the pressure plate fingers.

Here is a picture of the clutch linkage on a chassis that I only recently took the body off of. The clutch pedal arm is pretty close to where it would be with the body on.
Notice that both of the arms on the cross-shaft are nearly vertical, as well as the clutch pedal arm that the rod hooks to. The spring visible in the picture is on the brake pedal. If your pedal won't go down to where everything is like this, then your clutch cable ball isn't seated in the cup on the fork, or the fork is installed wrong, or something else is wrong inside the bellhousing. On this frame, the corner of the crossmember mounting bracket is clipped off (sure looks factory, not Bubba) to make room for the clutch pedal spring. I thought I got a picture of that, but I guess not. HTH BW

John, Bruce. Thanks to both of you. I think I've got it now. Next step is to drop in the rebuilt engine and bolt it up with the bell housing.
