Default 67 Upper Clutch Rod and Pedal Adjustment

I've got a 67 with a 200cu and 3 speed manual. The car has been sitting since 1982, and I'm working on getting it going again. So far I have gotten the engine running. Now I would like to getting it moving on its own.

Problems... The clutch pedal does not return correctly, it only goes back up about 1/3 of the way, and does not seem to be engaging when I fully depress it. I can pull it back up with my toe and it will stay at the top. The large spring is still intact on the pedal and seems ok. The upper clutch rod is way off center and is rubbing against the firewall where it goes through the hole. It is rubbing toward the passenger side.

When I have the pedal depressed, the rod gets close to the center of the hole. The rubber boot is long gone, what was left of it disintegrated when I touched it.

Here's a pic:



With the engine running, I tried to get it moving, but it just stayed put when I put it in gear and released the clutch pedal. No banging, no noises at all, just continued idling as if it were still in neutral. The shifter itself needs adjustment as well.

Any tips or suggestions are greatly appreciated.

It sounds like you clutch pressure plate might have broken. The return tension on the pressure plate should be enough to get your pedal to lift back up off the floor.

Is all the clutch linkage under the car still intact? The bottom springs are just there to keep the lower pushrod in constant contact with the clutch fork. If thos little springs have rusted away, you could have just had the linkage fall out of place.

Your Z-bar is supposed to ride on two nylon bushings. I think the V8 cars had a ball style bushing and the 6cyl cars had a sleeve bushing. They are somewhat interchangable, so you might find either (if they are still intact). When these wear out, your Z-bar will have extra play and could cause the upper pushrod to be off center.

Also make sure the bushing on the clutch pedal is still there.

Thanks so much for your help. I'll have to take a look and make sure all of the linkage & springs under there are still intact. Thanks for the tip on the z-bar bushings... I'll have to take a closer look to check that out.

My first mustang was a '67 I6 and I suffered from sloppy Z-bar linkage for a long time. Its really not that hard (or expensive) to correct once you dig into it.

Another thing to check out is the frame rail bracket that is mostely hidden by the steering column. Two bolts hold it down and it has lateral adjustment. These often get rusty or bent up and can lead to sloppy linkage.
