Hydraulic clutch has my vote, no linkages.

I've tried the PBblaster. Nothing. I went to war on it for another 2 hours last night. I lost. Here are some pics in a google drive folder (the forum won't let me upload): https://drive.google.com/drive/folde...AN?usp=sharing

What these don't show you is how little clearance I have to do much. Can't get a bolt extractor in there. Again, I've tried penetrating spray, propane torch, hammer. Any other ideas?

It's been awhile since I did mine, and as I said earlier, I have since switched to a hydraulic clutch, but as I recall, I just used a punch and drove the broken bolts through. I don't remember if the plate that you said you are prying on is a one piece assembly, ie, the bolts and plate are all one unit, and driving the bolts out toward the inside of the cowl will loosen it. At any rate, I just replaced the sheet steel plate with a 3/16" piece of flat stock, drilled it, and then I could reach up inside, hold the bolt with a wrench, and tighten the nuts from under the hood.
Another option would be to just grind the broken bolts flush with the firewall, and drill them out. It is not necessary for the bolts to be "captive", reaching up inside with a wrench is easy.

Thanks for sending in those pics, I have seen that pivot break before, but that is the first time I have seen it break at the bolts. I would think you would probably have to drill them out though. That would mean replacing the busted studs with bolts and would also suggest a backing plate to hold it more ridged. From what I have seen they break due to the fact that the bell crank is not perpendicular to the frame putting most of the load against only one of the pivots. When the engine is in the correct position, the bell crank is perpendicular to the frame making the clutch linkage work just fine. But when the motor mounts sag, the engine moves to the rear. This is noticed by the valve cover getting pretty close to the firewall, the engine side of the bell crank moves to the rear also. There are also nylon bushings inside the bell crank that will wear out. They would be item #10 on your diagram.

Ok... Upon my reassembly of my frame off '77 I was sooooooooooooooooooo exited to finally pull my Jeep out of the garage. I put my clutch in and the poopiety plastic bushing broke. This is the bushing on the clutch side of the linkage (I hate Crown).

Looking at the "Black Betty" set up but not sure how it works. Does anyone have pictures of it installed? I'm not afraid of throwing money at the problem, but $100 is $100.

Also, what is involved in switching to hydraulic? I've been so wrapped up in the rebuild I never gave the clutch linkage too much thought.

Thanks in advance.

Are your talking about the plastic bushing in the end of the bellcrank? The heim joint linkage still uses all the bellcrank stuff. It just replaces the rod from the clutch pedal to the bellcrank and i think part of the linkage from the bell crank to the fork.

I've got the Rugged Ridge kit coming tomorrow and hope to have some pics this weekend

Yes, the crappy plastic end on the bellcrank is my issue. I bought the Crown replacement and is is a POS. It is literally my weak link in the whole set up. I wish I could just weld the whole thing up and move on.

Well that sucks. I just bought a kit to replace both of mine from crown. I think I replaced the whole bell crank a while back (probably close to 10 years ago) with a crown piece and it has held up until now

I'm sorry you're having so much trouble with this. What with the plastic bushing failing upon install it seems that the linkage may have been binding up for some reason. If so, it wouldn't work well anyway. Detailed photos of your setup would be great as well. I've got to run to Portland today so I'll be pretty wiped out before I make it home, but I'll try to take some pics this weekend and post them in thumb nail section here.

The last time I bought the bushings I got them from the Jeep dealer.
