is my clutch disc backwards?

Well, forgive me for reposting this and I know what answers I am going to get most likely, but I am more looking for a second opinion.

I just finished putting in my new shortblock, and it fired up and runs great, but being that I had to take of the transmission, I had to obviously reinstall my clutch. I put a new retainer ring in it because it was a little bent. But now it will not go into gear.

It will go into gear when the car is off, and I can shift though all the gears, but when the car is started it won't go into any gear. It's clear that the clutch isn't disengaging.

when I try to shift it into any gear, it hits a wall, but starts to slowly roll forward when im trying to push it into gear.

I check through the tranny hole and the TOB is engaged with the clutch and when the clutch is depressed I can see the clutch fingers move like they should.

It is my assumption that the problem is the clutch pedal needs adjusted but I tried (somewhat unsuccessfully) and couldn't fix the problem. I put this clutch in a year ago and didn't need any adjustment then, why would it need adjusted now?

I'm going to try adjusting it more today when I get home, and bring it higher, but it doesn't seem likely to me that that is the problem....


What else could this be? The wave clip and retainer don't look damaged when I look through the hole, and a really doubt I installed the clutch disc backwards but it is possible..... Who has any ideas?



The slave cylinder also has plenty of stroke and I bled the line. The pedal is pretty stiff as it should be.

Wow! This is an interesting issue, but it sucks, sorry to hear this.

When I did my clutch a few months back, I believe I installed it with the concave surface facing toward the flywheel. I don't see how you could reinstall it properly without doing it like that.

Did you accidentally get your shifter cables swapped backwards. You never know, sometimes the silly stuff will get ya!

Damn! Good luck buddy.

If you have full travel of the slave and release bearing, the disc orientation is really about all it could be.
Was the protruding side of the friction facing the transmission or facing the flywheel?

Hey Super, you really think you can install it backwards? It seemed like it would be very difficult to do so. I mean, it is actually possible?

You know, like you could tell if the assembly wasn't fully seated. It took me forever to get it all torqued down.

But stranger things have happened.

I just re-read.... did you not remove the pressure plate? I had thought you had removed the clutch entirely. Obviously if you never removed the pressure plate then the disc couldn't flip

But yes, very possible to reverse it and it causes problems.

disc can rust fuse to the flywheel or pp. in which case it will need to be driven. try starting car in second. and drive car around with clutch pedal to the floor. had to do this once on a ferrari at work. actually stayed fused for good ten minutes. so I got to see what she had. not a bad job.

Whoops! I didn't read it right either. Sorry guys, I'm more than a few beers in here.

Update.

Did full clutch pedal adjust all the way out and also re bled the kind and topped it off with fluid, no suck luck.

As for the shifter cables, my buddy actually did that part while I was doing the timing belt but I'm pretty sure it's correct because I can go into all the gears when the cars off.

And yes I unbolted the pressure plate to get the tranny off. Put a new retainer clip in. Reinstalled it with the thicker spring side facing the transmission, I'm 90% sure of this.

I'm also wondering if the clutch disc got damaged anyway or any other parts got messed up during the install.... But I don't recall any thing that would have done this

Either way it looks like I'm out of options without dropping the tranny....

So I think I'll be buying a new clutch to make it worth all my trouble if dropping the tranny in the case that I didn't find anything wrong, at least I'll have a new clutch.

This I suppose could be a possibility, clutch was left unattended in my garage for a bit. I'll try to start my car in second today and drive it around the block and I hope the gears loosen up

That's weird, I'm interested in hearing what is found. For the record the clutch disc was in correctly if the protrusion was facing the transmission.
I can't imagine what else could have gone wrong though, especially since you said you were seeing normal slave operation and the bearing pulling away properly etc.

UPDATE.

The disc was backwards -_-

Live and learn. I'm pumped it's an easy fix!!!! And I got the tranny out in 2 hours flat with 2 friends. World record time!


The point is I get to drive my evo tomorrow with a new built 2.4L stroker in it which I haven't drove in 4 months, so I'm pretty thrilled.

Thanks everybody for the help!!!
