Hey guys
Does anyone know the "wear limit" on a new stock (turbo or turbo s) clutch? The manual gives the wear limit as .2mm, but does not give a measurement for a new clutch. Im just trying to gauge the current wear on my clutch (.7-.9mm).

Basically im looking for the dimension "X" in the pic:

Anyone have a new stock clutch lying around they could check for me?

To bad you didn't ask a 2 weeks earlier we just put every thing back to gether and on the motor

Yeah I have sorta bad timing... I should have measured daniel951's new clutch when it was at my house! But no... I had to forget!

Someone has to have a new clutch waiting for installation... Anyone?

I have a new clutch sitting at home, but I'm not sure the best way to measure it. Let me see what I can do when I get home (maybe tomorrow) if nobody else has been able to help before then.

Thanks Zero!
That would be great... It would be hard to accurately measure it without a mic... But if you had a really precise ruler, you could estimate pretty well.

I think I'll find a small dowel, that fits the hole nicely, push it in, mark the position of the clutch disk on it, and bust out my magnifying glass

I recall looking at my clutch disc, and saying 'Gee, this doesn't seem like a lot of friction material'.
I would estimate it's roughly 1mm without measuring it.

Mine is a turbo cup disc, but I am 99% sure the clutch material is the same as a stock turbo disc.

Sounds good... I don't know why they don't print it in the manuals...

Maybe someone has measured this already and can post it without zero going through the trouble?

Chris, search for a post I made over a year ago about the escort disc. I posted measurments in it.

Most people just replace them when they start slipping.

My life just got infinately more complicated. I won't be home for a few days. Hopefully within a week I can get some numbers, I hope that's not too late.

This might help, I have a picture showing how little friction material there is, it might serve as a rough guide?



Looking at the pics, I would say it's definately under 2mm.
I'll take a better look at the high res pictures to see if I can get some more accurate numbers.

Upon further review, it looks like the thickness of the material above the flanged rivet is about equal to 1/3 to 1/2 the length of the flanges on the flanged rivet (if that makes any sense). I would estimate that to be about 1.5mm, maybe as much as 1.8-2.0mm.

For comparison, the thickness of the friction disc on my subaru, with it's little 1.8L flat 4 is 4mm from the top of the rivets. I'm surprised how thin our friction discs are.

Hey Stephen what's going on man? I did a search but nothing with your name came up, did you start the thread or reply to one?

Peckster-
I have my clutch out for the engine rebuild, I was just checking to see how much meat is left to see if I want to replace it now or not.

Thanks Zero-
I'm really in no rush... It won't be back together very soon anyway!

cpt_koolbeenz

Anybody gotten time to get any numbers yet?

Magown

Beenz, I did a search but couldn't find anything. I recall getting the numbers from the turbo repair manual.
