I recently bought a kit from SR Motorsports including an aluminum flywheel and basically an ACT clutch kit. The ACT part inluded a new pressure plate, s/s disk, throwout bearing, and some other random parts needed. I'm currently sending back the pressure plate b/c it will not release. I've changed out the hydrolics, am getting full throw, and the fork is fine... leaving very few options. I've never really heard of anyone else having problems with ACT... normally they're a good company, but I was curious if anyone else historically has. Also does anyone have anymore suggestions for my currently nonfunctioning car?

One more question... what would happen if they had accidently sent me a TII pp? Would that even bolt up in the first place?

 

only prob i had was that after i installed it i couldn't put it into gear, but that was easily solved by replacing the hydraulics.

only thing i can think of is did you torque everything to spec? Did you check your tranmission fluid level?

 

How are you checking the clutch to see if it will release? Are you trying to shift and its grinding the gears?

The TII pressure plate shouldn't bolt up. At least not to a OEM N/A flywheel. If the aftermarket flywheels are the same, the the TII flywheel and pressure plate are bigger in circumference.

 

Mine kept destroying throw-out bearings.......after 4 I called it quits and sold it and then bought my TII.

 

JStewart, I'm having the same problems that you had... when you replaced the hydrolics, did you replace them all at once or part by part? I've replaced the master cylinder, but not the slave cause the guy said "you're getting full throw". I have a feeling that's the problem though.

Ok, I was just making sure that they didn't accidently send me a TII pp, which is why it wasn't working.

 

I bought a new master cylinder and rebuilt the slave cylinder at the same time. Yeah i thought i was getting full throw aswell but couldnt get it into gear. I would say get a new slave or rebuild it, i think it was under10$ to rebuild. Then make sure you bleed it really well and adjust your pedal freeplay.

 

Hrm. I just installed an ACT clutch and I love it. I still have the 'old' throwout bearing on it (~10K miles, Its a sacs unit, I hated the clutch so much I swapped it out after 10K)

Instalation was pretty flawless. Nice unit.

I'm going to keep an eye on this thread now to see if the dead throwout bearing problem is had by many . . .

 

after going thru 4 slaves n 2 masters i threw that **** in the trash and got an OS GIKEN TWIN DISK AND 9 LB FLYWHEEL.the act clutch is too much for the slave and master u'll see after a while, either get a custonm unit that pumps out more fluid or get sumthin else.askDVLS-7 on this forum he had the same problem with his but his bent the fork, after all the **** i went thru my fork finally broke the 12mm bolts! alot of people have probs with the act but they never bring it up.get sumthin else like a nice exedy.cost bout the same or a lil cheaper.

 

THOSE TROUBLES ARE WITH THE RED OR YELLOW ACT PLATE??? I KNOW THE RED ONE(EXTREME) HAS THIS PROBLEM ...IT DONT RELEASE BUT THE YELLOW WORK PERFECT

 

Are the hydraulics the same on NAs and TIIs? I have the yellow PP (heavy duty) and 6 puck unsprung disk on my AE, and it is doing just fine with my 100K mile hydraulics.

I have just been considering an ACT clutch for my 'vert, but after having read some of this I am having second thoughts. I am gonna keep a watch on this thread and see if any more positive things come up.

 

I've got the yellow one on my 'vert w/ 117K on it. I love it, no problems yet.

 

I know this is an old thread but I'm having some issues with my ACT HD pressure plate and just curious to see if anyone else has had issues with theirs as well. I could barely get the slave cylinder on because the clutch fork was pushed back so far. This is the reason why these things chew up throwout bearings, because the pressure plate is actually touching the throwout bearing when you put it together. I really dont want to spend a day pulling the motor and swapping back to the stock pressure plate again. When i try starting the motor, in gear, with the clutch it you can feel that the pressure plate still has a tiny amount of grip on the disc so it try to roll forward if your foot is not on the brake. I may try to shorten one of my other slave cylinder shafts down to see if it may help. If anyone else has experienced this and maybe has a solution, i'm all ears.

-This is all packed behind a 20B
-TII disc
-ACT Prolite flywheel
-ACT HD pressure plate

 

My TII has the ACT HD pressure plate, clutch and flywheel, the clutch fork was also bent and had to be replaced about 6 months ago. No problems since though

 

Well i ended up shortening the rod on the slave and now it disengauges, great! but for some reason im getting terrible pedal feel. I've bled it about 4 times now and it still feels spoungey.

 

Oh wow i thought it was me. I have an ACT on my 91 vert. It killed the throw out bearing and forced me to bleed the entire system. but its been awhile since that day and the thing HOOKS up ever since. the pedal is a bit stiff but im glad i made the change. good work out for you calfs!

 

Bah, i was retarded, i didnt have it in gear the last time i tested it so it was worse off then before. But i put the longer rod back in and adusted the clutch peadle adjustment rod and now it seems to be a happy clutch. Yeah they just like to eat throwout bearings because the pressure plate actually rests ontop of the throwout bearing, greatly reducing life.

 

Red or Yellow? To date I've never seen a factory painted ACT PP in Red, ever. If it came new with a red PP, might want to verify it's ACT as I don't think so.

The N/A slave uses a longer rod & doesn't fit the TII trans. & or the PP/clutch kit. It will cause the throw out bearing to spin all the time & die quickly. There's no other real reason why the extreme PP wouldn't disengage properly. That's not the problem with them, nor is it because they kill throw out bearing fast. The problem is that it puts too much pressure on the stock hydraulics, clutch fork & the pivot ball. The results are a bent fork, busted ball, blown slave or master. Normally the slave.

Someone said that the extreme PP broke the 12mm slave mounting nuts? hummm, that's odd. I just find it hard to believe that the steel bolts gave out before the aluminum threads in the bell housing. You know, seeing as how the bolts are much stronger. Over tighten those bolts & you'll see that the threads in the bell housing will strip out before the bolts do. As we always say to a friend of ours, "that never happened"
