And for the pilot bearing...(Whats left of it any way)

I used the grease and bread with a ground down bolt method to remove it by the way.

That pilot bush has also worn the tip of the input shaft....

I usually replace the bronze bush with a roller bearing unit from Dorman....

Suggest you bleed release bearing system with a pressure bleeder...

Good luck...

Well, I got it all back together.
Installed the clutch wednesday, put the tranny in thursday evening (with help from my Dad and my brother) (no transmission jack)
and buttoned it all up friday.

So far so good... clutch works much better, I only have taken the truck for a short test drive but so far I can say it is way improved.

My first clutch replacement is a success!
Spent some time in town with the truck the other day...
Clutch engages much more smoother now and the truck does a lot less jerking.
Replacing the clutch/components was a really good idea lol.

I still have my clunk noise from time to time when I disengage the clutch, but I think it's coming from the transmission.
Not going to worry about it for now.

Thanks goes out to all you guys for your helpful input and suggestions!

Well it's been a while but I wanted to do an update on this.
So the new clutch helped for a while but it's pretty much gone back to how it was with the old clutch maybe even worse I don't really know it's been so long.

Truck still shudders/clunks when I hit the clutch under load (mostly noticed when backing out of or pulling forward in a parking space)
(I think this is slowly getting worse over time)

Truck does not take off smoothly (shudders)
Strangely it seems to take off smoother in 2nd gear????
All shifting is semi ruff sometimes not to bad other times bad.(if I work the clutch just right it's not to bad but it seems to me it should not be so sensitive)
I think 1st to 2nd & 2nd to 3rd are the worst.

I'm begging to wonder if I have an engine/lack of power problem that is playing a part in this but not really sure.

BTW I have checked the u joints and they seem to be fine.
And there is no noticeable vibration while driving.

As soon as I get my 76 c10 on the road (witch could be a while) I'm going to park this thing and tare into it.
Untill then however I'm going to be driving it till it blows up I guess!

If anyone has any thoughts please comment.

Sounds like maybe broken motor mounts.

Or you could have worn it out again already depending on how you drive ???

I read the entire thread and had to reply. About 5 years ago I purchased a 1996 K1500. It was a real fixer upper. The body was great and very little rust. I have been driving standard transmissions my hole life, but driving the 1996 was really difficult. The foot pressure to push in the clutch was really extreme. If you tried to let the clutch out in first gear with any slippage the whole truck would violently shake. I found that if you let the clutch out slowly at idle and then applied the throttle it would not shake. The truck would almost stall so the timing was really critical. I decided with the problems in the engine, that I would replace the engine with a new GM crate engine. When I had it apart I noticed that the fly wheel was scored badly, and the pressure plate had some of the fingers bent. I installed a clutch kit, including pressure plate, clutch, both bearings, slave cylinder etc. I also replaced the pressure plate. Both engine mounts were broken and were replaced with new polyurethane engine mounts. Transmission mount was also broken in half, that was replaced as well. After the install was completed, the clutch petal force needed to press in the clutch was reduced by at least 70 percent. The whole shaking thing was fixed as well. I am afraid that I am not going to be of much help with sorting out your problems. I changed so much stuff that I don't know what parts fixed which problem. I suspect that the pressure plate made a big difference. Engine had a bad main seal leak that I think was blowing some oil on the pressure plate. The engine and transmission mounts probably amplified the problems that the clutch had. I think the heavy clutch had to do with the damaged pressure plate.
