I'm lost. I installed a new pilot bushing and throwout bearing the other day, tested the car, everything worked fine, clutch and all. But now, not 3 days later, the clutch won't disengage. I figured I'd try and see what was up, but nothing was working. I then tightened the lower push rod so that the was no free play in the fork just to see what would happen and still, the clutch will not disengage. I checked the bellcrank and everything is tight. I'm at a loss and any help would be appreciated.

Some of the cheap parts store pilot bushings have high iron content. May have seized on the input shaft.

Clutch plate may have flash rusted to the flywheel, or the pressure plate (or just might have stuck to it). Had that happen before a couple of times, especially after surfacing the flywheel. Sometimes depends on the manufacturer and the clutch plate material that I'm sure has changed significantly over the last years. Try a little more rpm and see if it releases with some torque if you haven't already done so.

Guessing won't fix it. You're going to have to pull the transmission and clutch and do a thorough inspection.

Fork tabs in relation to throw out bearing seem to be an issue for some . Some people seem to install fork onto bearing so the tabs rather than the fork apply pressure to bearing . Something to check if you are not sure .

I bought a '69 Z/28 back around 1980 that supposedly had a bad clutch. Guy tells me he put in a new 3 finger pressure plate and clutch disc and about a week later the clutch went.
So I buy the car and pull out the transmission. I look in the bellhousing and see the clutch fork is bent. I installed another fork and that fixed it.
Only time I ever dealt with a problem like that.
