New day, new clutch problem (Headscratcher alert) (Page 3/5)

Maybe cracked or broken friction material. When its spinning and free it remains free then shut it down and it gets jammed up again.

Honestly, if its that bad I'm surprised your still driving it. I would tear it back apart to find the problem, it should be pretty obvious when you see it.

The auto parts stores near me will lend an inspection camera for free - might be worth a shot.

New clutch kit is in, going to be doing the fix this weekend.

I have been doing some reading and it looks like some miatas were recalled in 2015 with the exact same problem of a randomly moving actuation point on the clutch and having to bust the clutch loose with the starter sporadically was due to pressure plate bolts backing out.

Are fiero pressure plate bolts torque to yield or are they reusable?

If they aren't reusable what can I get as far as replacements go for a 84 4cyl?

you should be able to check for the bolts backing out without even pulling anything apart. I typically just slap blue lock tite on them.

How am i supposed to get to the pressure plate bolts without removing the engine? Through the starter???

I am not a know it all, but I believe you need to drop the transmission to get at those. This would be a procedure that will at least give you a total inspection of your clutch issue

When I was thinking about it I got mixed up with flex plate. But I think you could see something from the starter side.

Iv never had to pull the engine to do the clutch on a 2.5. heck half the time I've not pulled out the transmission either.

Haha, I get that.

I have pulled this engine, transmission combo meal 3 times on this car alone. Its not the end of the world, and I have a pretty good system worked out, I can usually go full out to full in, in just about 6 hours. Its just dirty long work and I don't want to do it. lol. Looks like its coming out this weekend after all.

Somebody start a raffle. I believe its a damaged clutch disc or the fork is out of alignment with the throwout bearing.

And the raffle results are in, everybody loses, go home!

I kid.

Nah I open the bell housing to doomsday. Against all odds, the brand-new fork from Fiero store with less than 5k miles on it broke. And created the weirdest clutch issue I have ever experienced. 1 Finger on the fork snapped clean off. And the remaining fork put a bend on one section of the throw-out bearing flange. Which was why my clutch was randomly working and not working. When the good remaining fingerer was touching the bent area there wasn't enough throw to disengage the clutch. When I would bump the starter it would rotate the bearing to the nonbent area and the clutch would work until it would settle back to the bent side. Sigh. I did notice significant wear on the face of the bearing and the fingers of the pressure plate. No significant wear on the frictions surfaces.


What would cause a brand-new fork to lose a finger? Please keep in mind this is my second fork, my original one was broken in the same way, But I don't see anything wrong. It was installed correctly on the bearing, has good movement and the tranmission shaft has zero wobble. Any Ideas?
