Clutch Help
Just finished replacing the clutch pedal in my 65. No issues with the pedal. I did nothing in the engine bay other than remove and replace the clutch cross shaft return spring and steering column. Everything appears to work correctly when the clutch pedal is pushed in but when released there is a loud pop from the engine bay and clutch pedal looses tension and remains about an inch above the floor. It can be reset by pulling the pedal out. I think the clutch fork is not reseating when released but don't understand how the work I did could have caused the problem. Any help is greatly appreciated.

The ball stud for the cross shaft? What do I need to look for? There is a big glob of grease that has leaked past the felt washer. Same thing on the side that connects to the frame. The bolt was loose with fresh grease leaking. Do I need to rebuild the cross shaft?

cross shaft
the ball stud that goes into the block needs to be tight...and where the other end attaches ..there is a nut to secure the Z bar to it's final resting place...and a retainer that goes against the nut(last) w/ a tab to bend over(very small tab) to keep the nut from turning and loosening up...did you install the fork over the T/O bearing your self? and note how far it was pushed over the T/O bearing? not much to rebuils the shaft...just new plastic things that surround the ball and new felts...seems like it was over greased but that just leaves excess grease at each end...wipe clean for better inspection...you might have someone depress the clutch while you observe the action @ Z bar

I haven't changed anything with the clutch fork, z bar, or any of the linkage. I just replaced the clutch pedal. All linkage appears to be working properly. Only issue I noted was loose nut where the z bar attaches to the frame. There was play in the bar but I tightened the nut. Could this be caused by a need to adjust the clutch rod with the new pedal?

The four bushings for the clutch pedal? Yes
I was able to observe the clutch fork. It looks like when pedal is let out the clutch fork slips off the throwout bearing. The pop is the throwout bearing slamming back into place. The clutch fork then can't return to the correct position preventing the clutch pedal from coming out.

Where your clutch fork slips over the ball in the bell housing 'might' have broken off
allowing the fork to travel/**** sideways...
Take off your inspection cover and see if you can see something laying in the bottom...or...try running a pencil magnet in there and see if you catch something...

I think it's fixed, although I haven't gone for a test drive yet. I had to do some significant adjustment to the linkage but the clutch seems to work and I can shift in and out of all gears.

If you adjustment is almost at the end of the push rod...that comes from the clutch pedal...you might wan to seriously look at all of the attachment points. If these linkages are original..I would bet that there is wear on them...and either the shafts have wear on them...or the holes are beginning to look slotted. And trust me...a little bit of wear here and there can make a big difference in the overall operation of the linkage. The only area that should have a slight slot in it is where the rod attaches to your clutch fork.
