I just installed a new clutch, replaced everything except the flywheel, which I resurfaced, of course.
The new setup works great, but a puzzling noise comes from the bell housing when the pedal is depressed, even slightly. It's a loud clicking, a bit like when your headers aren't sealed adequately. The frequency matches the engine rpm. This is not the first time I have done such a job, but I've never heard such a noise. Any ideas?

In my experience, where bearings are concerned a clicking usually means a bad bearing, so I would think you very possibly got
a bad throwout bearing. One of the balls wants to be square instead of round! /wwwthreads_images/icons/frown.gif

/wwwthreads_images/icons/tongue.gif It could also be that a throwout finger is out of adjustment and sticking out past the other two. If the pedal has some slight movement in time with the click, that is a good pssibility. Check also to be sure that the flywheel and cover are running true with the crank. /wwwthreads_images/icons/crazy.gif

Similar problem happened to my buddy Crusty after a clutch job in his 7. Turned out that the bearing retainer on the tranny had broken, and the part covering the input shaft was riding on/rotating with the input shaft. Examination showed it to be previously cracked, and during the install it broke the rest of the way. It's probably a long shot, but you never know. Either way, you're looking at disassembly to find it.

Not that long a shot. This happens when the transmission is not lined up when trying to stuff it into the
clutch. One of the springs gets dislodged from the fork and breaks, pivots on the rivet, or winds up under
the fork.

Thanks for the conjectures. I found and fixed the problem. Here's what it turned out to be:

In order to remove the flywheel, I had to grind the heads off of the bolts. Since I had originally planned to replace the flywheel, I was not terribly careful about overshooting a bit. Unfortunately, it turned out that the guys at checker had quoted me the flywheel for an automatic and it's actually quite difficult to find one for a standard. 4wd Hardware has it, but the price is quite high, so I decided to try to use the old one. In order to compensate for the damage to the flywheel, I put washers under the bolts and used bolts which were slightly longer. I checked that there was enough clearance behind the crankshaft flange, but I didn't account for the fact that the crankshaft moves forward slighty when force is applied to the forks on the pressure plate. Thus, whenever I stepped on the clutch, the new flywheel bolts rubbed against the inspection cover. I fixed the problem by putting a washer between the inspection plate and the bell housing at each bolt. It works great now.
