ok, I bought a 89' gxl with 68,000 miles on it, it had a bad clutch, so I replaced it with a Rotary performance standard clutch kit, all good and well untill, i relized it was slipping, You guys couldent figure out why it would be slipping, mine you this is when it was stock. so i decided maybe my flywheel was reserfaced wrong, or maybe the clutch, so i ordered a stock replacement clutch and put that in (flywheel had been reserfaced perfectly) now its slipping even worse, I DONT GET IT!!!!! it was broken in and everything, i just dont know what the hell it is, the car is no fun to drive cuase everytime i shift at high rpms, the clutch gives and just starts slipping! WTF

so the new stock one, is slipping worse than the other on. but in the exact same way.

the only thing that i can think is that my car overpowers the clutch (with strait pipes and intake) but that wouldent make sense cuase it was slipping the same way when the car was stock! What is it? what the hell could it be? i really need help with this one!

Sounds like you need to adjust your clutch pedal. This is done inside the car, up in the dash. Youll see the rod from the pedal go into the firewall; this rod is the adjustment. There is a 10mm pattern on the rod and a 12mm locknut to hold it. Sounds like someone adjusted the pedal funny (you can do this to suit your personal preferences as to when it engages/disengages) and now that you put in a new clutch, it is preloaded a bit(adjustment pressing on the clutch a little all the time). Loosen the rod up and back it off some, then try it. It is possible to adjust the rod IN too far, in such a way that even though YOU are not pressing on the pedal, the adjustment is pressing in on the clutch even when the pedal is out.

I think that it might be the pressure plate if you didn't replace it.

ok, I just adjusted the peddle in every which way possible, no luck. I replaced the pp both times a did it and i had the flywheel researfaced to spec. I just took the car down the road after adujusting the peddle and bleeding the system and... i went through 1st gear, it was fine all the way to like 7,500, than i shifted at about 40 mph and i went through all 5 gears and stayed at about 45. I can drive it normal and its fine, it doesnt get any worse. oh yeah, after i went through all 5 gears... the pedal got really stiff, like my old rx7 was (87 se) this pedal feels really light, as did the rp one, and they both didnt grab untill the very end of the pedal travel. Help! If i replace it again i dont want it to mess up

You've got to make sure the throw out bearing is returning all the way. The only way a disc is going to slip like that, as long as it's not contaminated, is that there is not enough clamping force, which brings us back to the throw out brearing not releasing all the way. Are you certain that the pedal is adjusted properly, as Kevin indicated, and there is free play at the top of the pedal? If your not sure, you could always climb under the car, mark the location of the fork, or have someone watch the fork, then unbolt the slave cylinder. If the bearing is riding on the pressure plate, it will push the fork/slave cylinder forward.
Just a thought.

ra ra rotory

ill try that idea..... with removing the slave cylinder, thanks

is it possible i could have installed the throw out bearing wrong both times, and its only partially grabbing and the stock one is grapping worse cuase its not as nice as the rp one? you know what i mean?

does anyone have a pic of where the t.o.b should go (how it should go) i remember how i put it. if your looking at the shaft on the tranny.... i put it in front of the realese fork????? is that right

If you installed the t/o bearing incorrectly, backwards, which would be hard to do, you would sure know it, because there would be no bearing to rotate on the pressure plate, and you'd hear some unbelievable noise.

I havent really done anything as far as the transmission, but isnt the TO bearing just sitting on the end of the clutch fork? I mean if Im thinking of the right thing, you just slide it onto the fork..

Damn forum, lost my post. Anyway, the throw out bearing is supposed to be CONNECTED to the fork, the fork forms a U at the end, and on the bearing you'll notice two flat spots where the fork slides in, generally you pull the fork forward and slide the U into the bearing and then push it back onto the input shaft and it's all good to go. Now if you just slid the bearing on, and didn't connect them, that could explain your slipping because it's forcing the bearing to be further forward than it should be, which could cause the clutch to be engaged prematurely. Just an idea, if you didn't put it on properly.

HAILERS

Take the oil filter off. Reach back there and see is there is at least a tiny amount of play b/t the fork lever and the slave cylinder rod. Not much, but at least something.

I know there is a limit to refacing the flywheel, but I don't know the spec.

ra ra rotory

yeah the flywheel is researfaced to spec, its 63/1000 of an inch or something, its right anyway, the to bearing is installed correctly, it looks like we canceled everything out except i havent checked the free play on the clutch slave cylinder. ill have ta go check it out...

Could be a couple things.

1) Pedal not adjust correctly
2) Bad master or slave ( you meantioned a weird pedal)
3) Bad pilot bearing seal let grease get to the friction surface

My guess is either 2 or 3. If it's 3 then you just need a new disk and to rub down the pressure plate and flywheel. You'll also need a new seal (10 bux I think). They are fairly easy to cut too when you put the tranny up. When I did my clutch, on my first attempt to put it in, my dad slipped with the 2x4 (on the sway bar to the front pulley to prevent the motor from rocking) and I couldn't get it to go on. When I pulled it down, I took a break and when I came back, I looked up in the hole to make sure it was disk was in right and noticed a small chunk of rubber in the hole. It was the pilot bearing seal. If this seal fails then all that grease in the hole can fly out onto the disk which will make it slip like a bitch. Provided your master and slave are alright, that's about all it could be. Good luck

Cory Simpson

I am going with cbrock I think that there is grease getting out from the pilot bearing seal and getting on the clutchand causing it to slip. Did yu replace the pilot bearing and the pilot bearing seal when you put a new clutch and all that good stuff in.

ra ra rotory

yeah, thats the thing, i replaced the seal the first and second time, when i took it out the first time the seal was properly seated, and im pretty sure it is this time, what kinda grease do you have to use? I used a high temp multi purpose grease, the kind in those little tubs.

that's what I used too. Something must be hanging up on you then. Generally when the hydraulics fail it's stuck engaged and you can't shift. How many time has the flywheel been surfaced? Lastly, you must be getting really good at pulling out RX transmissions

ra ra rotory

the flywheel was researfaced once, the car has like 72,000 miles on it and this was its first clutch. What is the best ways to check if the hydrolics are bad? Yeah, i am pretty damn good at it now. I tuaght myself how to do it the first time using you guys and a haynes manual (wish i could teach myself how to spell) and the second time was a breaze, i dont have a problem pulling it again as long as i know what is wrong, i just want to know what is wrong!!!! haha thanks for all the help

ra ra rotory

i stuck my hand down to where the realease for touches the realese cyilander. it had didnt really have any play, so i pushed on it a little bit, to the point where it would have like 1/4 play (i know it doesnt do anything but i did) and i went to press the clutch peddle and it was on the floor, did i mess up when i bled the system? how should i bleed it>? I used a one man bleeder and im assuming it worked fine......

cbrock

iTrader: (1)

You mean stuck to the floor? That is from either a bad bleed..which it sounds like you did alright. Again though, bad master/slave would make the clutch stay engaged. The only thing I can think of now is that the pedal was set too far out..ie the pedal was being pressed in just a little from the adjustment. So now what you have is a over heated disk and flywheel/pressure plate. Once you get heat spots in it, your done. I guess pull it down and check for spots and such on the flywheel and pressure plate. Double check the pilot bearing and the throw out bearing. The flywheel and pressure plate can probably be fixed up with light sanding, but the disk could be shot. Remember the system is limited to 5 moving parts 1)pedal 2)master 3) slave 4)throw out bearing 5) pressure plate....I betcha 20 bucks it has something to do with that


Does the tranny make any weird noises? Just trying to localize the problem.
