Clutch not fully disengaging
I'm in the process of doing an automatic to T-5 conversion. I'm having a problem when the car is running, I can not put it in gear with the clutch pedal pushed all the way to the floor. If I kill the engine and put it in gear the car will start but you can tell the clutch is not fully disengaged by the sound of the way it starts. Also if I start it in gear, I can't take it out. I checked and saw that the slave cylinder is moving the pivot arm about half an inch like the book said it should. Is there any way of bleeding the clutch assembly? Any other ideas?
Thanks,
Scott

Yes you can bleed the line . Look on the realease cylinder (lower part of the line) thier will be a small alen bolt , bleed just like you would your brakes. That would be nice but its kind of sounds like the throwout bearing may be on backwards . Did you put it on with the bearing facing the crank . Also did you have the flywheel turned? .

I installed the throwout bearing with the bearing part facing the flywheel. I did not have the flywheel resurfaced but it appeared to be in decent shape. I tried bleeding the system and that didnt work. Any other ideas?

Are you reusing the clutch that came with the flywheel . If the clutch is torquec down and centerd it should work . Do you know how the clutch worket in the car it came from , that is if is used .If the flywheel was not turned and you are useing a new clutch it may not be seated correctly .

The clutch and flywheel are both used. I got them both from the guy I bought the transmission from. The clutch is a centerforce and supposedly worked according to the guy I bought it from. Do you know if the source of the problem could be the pilot bearing? That is the only thing I installed that I'm not sure I put in correctly. Which way is it supposed to go in? Is the side with the bearings supposed to face in or out?

I do not know whitch one you have ,but I had a summit roller pilot bearing and I think I put it with the bearings facing out . I put the more rounded part in first , in the crank . Did the friction plate have writing on it telling you whitch way is to face the flywheel . The pilot bearing should not efect it , would just make noise . You said that the clutch fork moves a 1/2" but how does the pedel feel sponge at all? .

I also used a summit pilot bearing but I put it in the opposite way that you did. The pedal feels spongy 3/4 of the way to the floor. Its not until the last 1/4 that the pedal feels stiff.

My pedal feels kind like that too maybe 2/3 of the way down new clutch too . I realy don't think the pilot bearing would stop the clutch from working . I would try bleeding one more time befor taking apart . How about that clutch disk did it tell you whitch way to install . If you take it apart I would install a new clutch kit and have the flywheel turned . I know that sucks but not worth the hassle of reinstalling a bumb clutch .Or at least get a new friction plate from centerforce and have the wheel turend . That would be less .

I'm going to do exactly what you said. Most likely I will have to take it all apart again and when I do, I'll probably go ahead and change the clutch. I'll let you know what happens. Probably be another week before I get to it.

if you can't get it to work by bleeding it (usually isnt the problem) then its a pretty safe bet that the flywheel has been turned 1 too many times
this happened to me earlier this year......all it takes a couple thousandths too much and the clutch will drag because there isnt enough throw in the slave to release it because its further away from the the transmission.

I'll bet the throwout bearing is installed on the fork wrong. I did it before and had the same problems your having. Here's a link for the right way to install it

Thanks for the help guys. My next step is to replace the flywheel with a new Hays flywheel and I also ordered a new centerforce clutch. When I take it back apart I'm going to see if I put the TO bearing on properly. I'll let you know what happens

Nice choice money well spent . The clutch kit sould come with a new TO & pilot bearing .Get that other pilot out of thier , evan if the kit comes with a brass one . Remeber the the fork goes behind the bearing (or the larger round part) on the tranny side . PM me if you have anny ?s Good luck .
Is the flywheel OEM or aftermarket may be 84Z28350 can get you a mesument and save a few bucks .

Well if any of you are still checking this post, the problem was the T/O bearing. I didnt have it in the clips on the fork correctly. I still went ahead and put in the new clutch and flywheel. Thanks for the help guys.
