miata xtr 1.6 clutch kit on my pops 92 miata
 

ok well I'm not a noob i did search and found little but a page on adjusting the pedal..

i have a 1.6 miata 1992 with a xtr clutch and flywheel kit

the clutch doesn't release at all.. Ive moved the clutch rod out a lot and its still not disengaging..


The throw out bearing is moving as much as it seams possible and ill mess with the pedal settings again tomorrow.



I think what is really wrong is a problem with the flywheel being machined incorrectly. i happen to have a shim for my turbo escort with a bp. i know it fits the miata flywheel bolt pattern and i was considering pulling everything back out and tossing it on.

what do you guys think have you seen a lot of problems with these clutches?

We bought it even though it was seriously to low of a price because my friend has used xtr on two of his cars and had no problem.

any help greatly appreciated

Are you talking about the freeplay adjustment rod underneath the pedal?

yeah the one that attaches to the pedal arm it had a 12 mm nut locking it in place

ok i adjusted it as per the spec sheet i found on anther thread where every one was flaming a guy :)


its still a no go im thinking this must be a problem with the throw out bearing not being correct it looked the same but i think its not i might have a escort gt one from my zoom kit lieing around to compair it vs the old exedy one vs the xtr kit trow out bearing

I'm willing to beat the XTR kit is actually made by Clutchnet....

I have an XTR sitting in the trunk (not going to install the shit), and it looks just like that Clutchnet.

During the clutchnet group buy, there were more than a few members that ended up in the same situation.

I currently am still using the clutchnet disc, but an ACT PP. Same with Newbsauce.

so is it the cover or the disk that causes all the problems?

i just took the trans off again and compaired the throw out bearings the new one is the same as the old one or real damn close..

that was my conclusion. The throw of the diaphragm was off, and the friction surface was not releasing.

When i finally used a few washers to bring the PP closer to the TB it worked, for a day.

interesting

now the miata is in the air going no where


it looks like you might have used a few to many washers and contacted the fingers to the disk?

I'm in email communication with gripforce where I got the xtr clutch.
I also filed a complaint on paypal.

So hopfully we get a new working cover form them.

carolina clutch usually has the best deals on ACT.

what do you guys think of shimming the flywheel is it possible a 50 thousand'th shim might move it out far enough or maybe two shims behind the flywheel?

this is what i tried. one shim wasnt enough, two worked, but then like i said, it failed.

Do you think the failure was caused by the fingers pressing to far in and contacting the disk? they look bent up to me?

I tried one shim did not work

I will try a stock exedy cover in a day or so just so i can get the car back on the road.


What do you guys think of putting in a 50 thousand'ths flywheel shim and then shiming the PP

Maybe its possible 2 shims might have worked if there was some adjustment to the clutch pedal so it didnt go to far in ?

this is what i get for buying cheap shit. I should have turned /shimed the stock flywheel and put in a stock clutch pack now we just :jerkit: and r/r the tranny 10 times.

I also had to move the rod on the pedal all the way out, i think it was making the TOB travel too far and had too much angle at full reach and caught caught in the fingers.

I've never heard of anyone having problems with the ebay kits. I know the F1 kit is clutchnet parts, I assume the XTR is as well. I think when we had a group buy for clutchnet kits, there was a 50% failure rate, then a bunch just returned them and didn't want to risk it.

I was able to return the PP for my money back at least. gotta love being able to do a clutch job in under 2 hours now though....

yeah i was really surprised I'm able to pull the little 5 speed out of the car in about 30 minutes now..

I drove it up on ramps then jacked the back end up and put it on stands

put a jack on the oil pan to tip the engine and pulled the bolts using my snazzy ball joint 17mm and 14mm swivel sockets and my impact gun.

i also didn't separate the exhaust at the down pipe. i pulled the air box then, i took the heat cover off and pulled the manifold away from the engine.

i was intimidated with all this ppf talk in my Mitchell's i feel real confident doing a clutch on the miata

now if i could just get the clutch to disengage

ok i dont ave a photo hosting accoutn so i uploaded the pictures i have to my myspace....hopfully this works


MySpace.com - TorqueTuning miata xtr junk


They are telling me its instalation and not a problem with thier clutch pressure plate


ohh and btw

www.gripforce.com
Speed Solution International
F1 Racing Technology
Speed Motorcars

They are all connectedin some way or another

this is the last clutch i buy from them unless they can get me a working pressure plate.

of course they are.

yeah, like i suspected, all made by Clutchnet. I'd call them directly and see what they can do for you.

they said return it and they would give me all of my money back if it is found to be bad. if they think its fine i get only 50% back for restocking a non new part



interestinly i found that a stock disc works great with the whole setup

wow light flywheel is nice! im breaking it in on a stock exedy disc but this will work for now we only baught the kit becuase the flywheel had cracks from previous owner dropping the clutch.. and the only reason we even took it apart was the trow out bearing was maiking noise probably from miss adjustment


anyway where do i get a new rubber boot to cover the hole in the floor?? His is completly ripped apart.
