Hey folks, Long story short is I just finished re-installing my new engine with all of the components. Everything looks perfect, and all I was trying to fix to have it back on the road was my clutch that felt like it had a air bubble in the system and I was ready to go.

So yesterday night I spent I don't know how many hours, with different techniques, trying to get rid of what I thought the problem was, a air bubble. But with the press, open drain plug, re-press until stiff and etc etc technique, it did not help. I also tried pushing some fluild from underneath with my vaccum tester, and I also tried pulling the liquid out by force with the vaccum tester, I must of drained at least 300ml of fluid before I decided to give it another try.

I get back in the car, I start it, and the clutch is still stiff, but I can't engage any gears, I can put it in by pulling hard on it, but I can't drive like this, and no one could either. So I decided to test it once in gear, applied the clutch and the brakes, and the motor dies out. Like the clutch is not disengaging.

Now I look at the clutch, and the way it works, from the peek hole underneath, and you know the thing thats really disturbing me is that you see the throw out pulling the diaphragm, you see the clutch disc moving towards he tranny, but just barely. I'd say that theres still point of contact on it. I would be suprised if the clearance between the flywheel and the clutch disc would only be a couple of melimeters.

You hear it slip when your pressing on the clutch and brake while in gear. You hear it scraped on the flywheel.

Now the only thing that comes to mind is, can a clutch disc be installed upside down? I've got a ACT Street lite flywheel with that, and I know that the center is a little different because of it beeing thinner than the stock one.

So thats my question... is it possible that my disc is upside down?

 

maybe if someone had never installed or uninstalled a clutch disk in their life. there would also have to be room for the sprung hub to sit inside the flywheel in order for the pressure plate to be able to bolt down.

 

Yes, I've seen it done and does exactly what you describe.

 

Actually, act had a little problem with some of their clutch discs a while back. I helped a friend change an act clutch in a prelude a few months ago and the same thing happened. Heres the thing, the splined section of clutch disc was too tall and would barely make contact with the pressure plate when you would press the pedal. Just like your car, it was hard to change gears, we thought the slave cylinder was bad also and ended up changing everything that had to do with the clutch hydraulics. After the 3rd time we pulled the transmission i noticed a very slight wear on the splined section of the clutch. This is where act messed up and made the collar too tall. When you would press the pedal in it would still press the clutch plate against the flywheel causing unwanted constant contact with the flywheel. I think you are having the same problem. It is very unlikely that you have the clutch in upside down, but with the symptoms you explained you are having i think it is more likely you are having this problem. Either way you are going to have to pull the clutch out and see. When you do, check the collar height and width against the stock one. Also check for any contact between the collar and the pressure plate. Any contact between those two parts are not allowed.

I hope this will help, let us know what the problem is.

Thanks for the info, I took the tranny out yesterday, I didn't think it could be that simple from under the car since i've installed it out of the car right before this time.
But yea as I thought, the clutch disc was upside down... rofl..

I'll pay more attention next time :P
