clutch problems WTF????

MY father replaced my clutch while i was working. It wont go into gear. It grinds when i have clutch to floor and try to go into a gear. I already have put it into first and started it, and it will move. I have bled it several times. 87 GMC R1500. Also I have removed the slave cylinder, and the clutch fork, with no pressure on it, will move back and forth by itself about 1 and half inches. Is that my problem?

Be patient man someone will come along but to me that travel seams excessive, but I could be wrong.

Did you replace the throw out bearing...and if so was it the right part number? Back when I had a manual transmission in my square, the clutch wore out...we replaced it, adjusted the linkage and all along it was the WRONG throw out bearing that we installed that caused the problem.

It could be your problem. There is 2 different throwout about bearings. A short and a tall. If you need the tall one, and a short one was installed, well then there is about an inch of free travel and the throwout bearing is barley getting to the pressure plate fingers to release the clutch. Bad news is, the trans will have to come back out to swap the throwout bearing. This is of course if I am understanding what you're saying by move back and forth by itself. Obviously is does not move back and forth by itself, you are holding the clutch fork and moving it. But what you are saying is, you don't feel any resistance whatsoever right? You can move it back and forth by hand before you feel it touching the pressure plate fingers? Do you have your old throwout bearing? Did you dad compare the 2 throwout bearings?

Ohhh, and are you 100% positive that the clutch fork is on the pivot ball? There should be 2 little sprung fingers that hold the fork to the pivot ball that the clutch fork rides on.

Could the clutch be in backwards? It has bee 40 years since I messed with one, but I seem to remember........

I'd wager its either the wrong throwout bearing or the TO bearing is installed into the fork incorrectly. Both are easy mistakes to make.

Normally that can't be done. I'm sure some scenarios it's possible but in most cases the springs and hardware in the center of the disk won't fit up against the flywheel side and have to be into the pressure plate side. The flywheel center offset isn't deep enough so I doubt this is the problem. Most likely wrong TO bearing.

Thanks for for the response guys. Looks like im going to have to drop the transmission again. Dammit. it is what is i guess

If it makes you feel any better I'm about to pull my SM465 for the third time since I bought my truck last April Good luck.

It ~shouldn't~ go in backwards, but that doesn't mean people don't do it. When the clutch disc is in backwards, the clutch itself is clamped by the pressure plate itself against the flywheel bolts, and the thing never releases.

I wager a case of Canadian Beer that it's in backwards.

Well, I'm going to agree with you and I won't take that bet. BUT, I'll have to keep the rest of my comment to myself if that's what has happened cuz I sure don't want to offend anyone, and I'll never knock anyone for trying. If you know whutta mean.
