TII Tranny/Clutch problems
hi guys,
so i'm having a bit of an issue with my TII tranny, ACT 6puck sprung kit, new pilot bearing, and new TII slave...
i'm unable to shift into gears once the motor is started. i have read this could be due to a seized pilot bearing so that has been replaced and greased properly (old pilot bearing looked find and needles were still good). tranny went back in place without any issues. slave cylinder is new and has been bled appropriately ( i will try to rebleed again later though). i get about 1/2" of travel at the fork which seems to be right.
if i start the car in gear, rear wheels turn even with the clutch pedal pressed in so it seems like the disc is making constant contact. but without the driveshaft in place, i can shift without any issues...shouldn't i have the same problem with or without the driveshaft installed? anything else i should consider?
thanks guys

if you could check how much movement you have, that would be great...i saw a few posts saying 3/8" to 1/2" of movement at the fork. i also just posted a request for pics of how the throw out bearing should be installed (in the 2nd gen forum)...maybe that's installed incorrectly?

FB and FC clutches are the same type (unlike the FD), so the throwout bearing installs the exact same way on both if that helps. Other than the clutch diameter being larger on the T2, it's the same type of setup. I will try to get a measurement on how far my slave pushes the fork tonight - at least it'll give you a baseline...

not a problem and thanks for checking. i'm going to drop the tranny and see what's going on. the only thing i can think of right now is that it's related to the throwout bearing, fork, or the pivot. i doubt it's the pilot bearing. hopefully will be apparent when i drop the tranny once again.

Yeah maybe the little "spring" that holds the throwout fork onto it's pivot ball is messed up and the fork isn't working correctly or something. I also doubt its the pilot bearing. Not good to drive with a broken/failing one, but usually it just slowly kills the trans, doesn't render it completely inoperable like your experiencing...

funny u should say that...
yesterday i did a quick test. with the tranny in neutral, rear wheels don't turn when i manually turn the motor. with it in first, the wheels turn...so ruled out the pilot bearing.
so today i took a 2 hour lunch today to drop the tranny. at first, nothing was out of the ordinary. had new throwout bearing in the garage so decided to swap that out. when i pulled on the fork to get the bearing out, it just came out without any effort. the spring was not even seated under the pivot and just sitting on the top of it. once i changed the bearing and put it back in place, i made sure the spring was installed under the pivot. by doing this, i could tell that it changed the pivot point of the fork. i did not get the chance to button everything up but feel pretty confident that was the issue. will know more this weekend when i get a little time to put things back together.
btw, in 2 hours, i was able to remove the slave, drop the driveshaft, drop the tranny, replace throwout bearing, and put the tranny back in place...man, i don't want to do this again for a while but at least i know i am pretty good at it now (fourth time installing the tranny now).

so that was not the issue. i'm still trying to figure it out so any other recommendations would be great. i don't think it's the fork now cause i had adjusted the pedal rod enough to preload the throwout bearing, pushing the finger in more than normal. will drop the tranny once again...but no idea what to look at next.

pilot bearing is good, just verified that again. i went as far as removing the aluminum flywheel off this time around and that looks fine as well.
i don't have a stock tii one but i do have a 4 puck disc sitting on the shelf and it's a little thinner (more wear on it). the difference is the spline is a little thicker (height wise) but i don't think that would matter as it's on the tranny side. worth a try i guess.
maybe i have a bad pressure plate? it's not fully releasing the disc so that's the only thing i can think of.
i've verified the flywheel part number is correct (for the motor). i've verified the pressure plate part number is correct (for the tranny). the 6 puck disc looks fine.

You already adjusted the pedal throw correct? I mean the adjusting rod behind the pedal that goes into the master cylinder.
Only other thing I can think of is bleeding he master cylinder. When I had to bleed mine I had a helluva time getting it to bleed properly. Ended up back bleeding it kind of at the master, putting the hard line back on, then bleeding it at the slave again. Was a total pain and a lot of brake fluid wasted but it eventually worked.

so finally resolved the problem! it was not the pilot bearing, pivot, throwout bearing, fork, or slave. i had my daughter help me push the clutch in while i checked underneath. one part of the ACT pressure plate would not disengage from the disc (there are three springs that push the pressure plate onto the disc and one of them i had to use a screwdriver to pry it loose). ordered a brand new Exedy Stage 1 kit (with HD pressure plate) and am now good to move forward. man, what a pain. i had to remove the tranny i believe 4 times for this issue.
