Made a dump run this morning, and when a couple miles from home I went for a gear change and somthing in the clutch system let go, the pedal got real easy to push and the clutch would not disengage by depressing the pedal.
My first thought as I was limping home in second gear was the clutch linkage or throw out bearing fork broke.
When I got under it at home all the linkage and fork were fine. Removed the expection cover and found this, half the fingers don’t look right. Are they bent, broken or stuck. I have been working on cars and trucks all my life and have never seen this before. Anyone else? And to add insult to injury it’s a high dollar center force clutch with less than 5000 miles on it.
 
All that is good, I put a new engine and the clutch in it in 2019 and it doesn’t get driven much, mostly to the mountain in the spring and fall. So no more than 5000 miles, it was weird when it broke, I was rowing through the gears like normal off of the stop sign, when I went to go from second to third, I pushed the clutch and felt the normal pressure until it got About 3/4 of the way down then it felt like somthing broke and the only resistance I felt on the pedal after that was the return spring and it wouldn’t disengage. That’s why I thought the linkage broke of fell off. After looking at it I think somthing with the pressure plate fingers jammed, stuck or broke and I’ll be pulling the transmission.
 
Maybe something broke or bent on the the throwout fork or pivot.
Since it was working for 5000 miles, I must assume the throwout bearing itself is the correct one.
 
Been reading, I think what happened is one of the springs in the clutch disc came out and jammed up in the pressure plate, never heard of that before, but the net says it happens, I can’t think of anything else that would cause it, either way the transmission and bell housing are coming out.
 
So today I determined the whole thing has to come apart, I pried around the clutch fingers trying to pop them out, a big retaining ring fell out and now everything just flops around.
I pulled the driveline to the divorced transfer case and pulled the shifter out. Next go will be the cross member and the transmission. Just a little at a time. Interested to see what caused the problem, the new clutch won’t be centerforce. I happy the transmission is divorced and don’t have to pull it.
 
When pulling my K20 trucks transmission and transfer case i split it the first time then I found it was easier to just bolt corss member to transmission jack and lower the whole mess to get to my clutch I never worked on one with divorced transfer case has to be unique.

Being divorced makes it easier as after the driveline between the transmission and the transfer case is out I have room to get the transmission out without removing the transfer case. If it was mated it might be easier to pull the engine.
 
Well there it is a 4 year old $600.00 clutch, 5 clutch pads fell off and the pressure plate destroyed.
All done by an old man on a dump run WTF. Next one won’t be a center force clutch.
 
I have no idea, guessing maybe a pad fell off taking others with it, then the pressure plate tilted because half the pads were missing on one side and blew up?? Did it at the exact time I pushed the clutch in for a gear change.
