    Ok, I reconnected everything, got the clutch linkage, and transmission shift linkage all back together and adjusted properly. Now I've got something weird goin on here I went to test the clutch by depressing the pedal and using my toolbox (which is full of tools so it's pretty heavy) to hold it down with the transmission in gear. I then went to turn the driveshaft by hand, well the shaft turned without resistance from the transmission but I heard this God awful scrapping noise (the clutch disc scrapping the flywheel). The flywheel was resurfaced and it has a new preasure plate so i'm wondering if maybe it just needs breaking in. The clutch pedal is even with the brake pedal and I can feel it disengaging by a slight tap on the clutch pedal so it's pushing the levers on the preasure plate in all the way and when I let up on the pedal it returns to the same height so it's adjusted properly. I dunno what the deal is here I hope I don't have to pull everything apart again cause it was hell getting it all back together.

    Clutch

    I'm not to sure you have anything to worry about, with engine off the clutch disc probably is just not completely lid back on the trans input shaft. When the engine is running, centrifigul force will force it away from the flywheel. Could be a slight defect in the lining on the disc too. In the old days we sometimes put the car against a pole or tree and gently burned the disc in. Not a good idea though, drive it for awhile and if it shifts good and doesn't chatter should be ok.

    Like Old Guy said, there's probably nothing to worry about. You didn't install the disk backwards (hub towards the flywheel)? Seriously, two years ago I installed a Center Force clutch and one of their "self-centering" throwout bearings. The first time I pushed in the pedal with the engine running the clutch howled like crazy. For a moment I thought I'd have to take everything apart again. Two or three more pushes on the pedal and the noise decreased and went away for good. Seems the "self-centering" bearing had to be used a couple times till it aligned itself. Good luck.

    Not backwards thankfully :), hub is inside the preasure plate. My friend had that happen to him with his Toyota awhile back we had to take everything apart again and flip the disc over so he knew which side went where :D. I've been told by a couple other sources that it could be some residual dirt on the disc or flywheel that didn't quite get cleaned off (cause we cleaned the disc while it was out of the car sitting on the Clutch Pilot Tool) and it should go away. I Hope!! (Fingers crossed). I really won't know anymore til I fire the car up and try to drive it around the block a couple times I will of course immediatley post an update.

    Seems ok

    Well I fired it up, it started right up with no problems the disc chattered quite loudly at first and smoked quite a bit, the linkage needed some adjusting so I had to shut it off and do that, the second time I fired it up it chattered a little bit more drove it around the block pushed the clutch pedal in several times it smoked some but that gradually diminished I could still smell it though but that seems to be slowly going away it shifts fine and the clutch doesn't slip so thats good.

    Clutch

    Just curious, did you install a new disc or use the old one over?

    I have never had a clutch smoke on me after an install. Is this common on the older cars?

    That sounds really odd to me.

    Lack of proper adjustment shouldn't cause that much racket and smoke. Either it will not disengage, or engage fully, but smoke and scraping noises seem really weird to me.

    I didn't use a brand new disc so thats probably why it was smoking. The old disc still had alot of life left in it just wasn't worn evenly :(. Last couple of times I have fired it up it hasn't smoked at all so i think it's past the smoke in period :D. My friends car smoked quite a bit at first to when we did his clutch he used a junk yard clutch disc (I wasn't about to do that if mine needed replacing). Gradually his stopped smoking too and now it works fine as well so I guess it's a used clutch disc thing. I used the old clutch adjustment rod (which is slightly bent so I need to get another one out of the junk yard eventually) cause this other one I had wasn't long enough, and I adjusted the linkage down to where it was before this entire thing began :).

    Oh and Max it wasn't the linkage causing the chattering and scrapping i'm sorry I should have been more clear on that. The linkage was posing a drive ability problem as the clutch pedal would have to come too far out before it would engage the clutch and I had to bring my knee back almost to my chest lol you can see how that would be a hazzard on the road :D.
