I am trying to install a used stock clutch. I don't want to have to go through all of this twice. The story is that the clutch has 11,000 miles on it. I need to know that it's not going to slip before I install it though. Thanks.

 

I would say that the clutch disk is pretty worn out, and if you are running a 35R like the signature says, then don't even bother putting it back in.

 

It will be with stock turbo.

 

all that work to pull down the tranny i would just buy a new one

 

the pressure plate has some decent hot spots, and there is not a whole lot of material left on the disc before it hits the rivets.

For the amount of labor money and/or labor time, its much worth it to buy a new one.

"Why is there always enough time to do a job twice, but never time to do it right the first time."

 

I agree with him. Better to do it right the first time than to have to take it down again. Well unless you get some type of pleasure out of doing it that is.

Oh and the disc does look shot. Not a lot of life left in it.

 

I'd never bother with a OEM replacement clutch (too fragile) unless you're concerned with warranty issues - go with something that has a chance of lasting.

 

I don't like the looks of the photos but I have seen much worse. Regardless, check for yourself by the following:

Pressure plate: Lay a straight edge on the face of the pressure plate to check for warpage. Measure how concave the surface of the pressure plate is by using a feeler gauge between a straight edge and the inner portion of face of the pressure plate. If it is more than about .020" then it is pretty bad and should be thrown away.

Disc: Usually a used one is not worth bothering with but if you are wondering how much life it has left, measure the thickness when the disc cushioning is compressed. For reference a new disc measures about .315" thick and worn out is around .250" when the pressure plate hits the stops on an EVO. You can compress the cushioning with the micrometer to get an accurate compressed measurement. If you don't have a micrometer, you can do this with a caliper and a bench vice or even a pair of vice grips. First clamp the discs friction material in the vice or vice grips and then measure with the calipers right next to where you are clamping.
