Pressure Plate
I have the ACT Extreme setup and I plan on keeping the same setup after the everything goes back together. However, I'd like to make sure that everything is up to par before it all goes back together so I don't have to tear it down again hopefully any time soon.
The disc, while it still has some life left, needs to be replaced now rather than later. Instead of buying a complete kit, I'd rather buy a replacement disc.
That said, I don't know the first thing about judging the worthiness of the pressure plate. Until I get home, I cannot post any pictures of it's condition, but I can say that the fingers are all at the inclined angle normally seen on a new clutch, none of them are bent in any odd way, and the only wear seen on them is at the tip where the release bearing sits. On the plate side, a few small burn marks are visable, but the plate itself is not warped or pitted. Overall, I feel that it is in good enough shape, but other than having messed up fingers, I don't know what consitutes a "bad" pressure plate.
Anyone care to enlighten me? Thanks.

To be honest, I have never seen someone break a pressure plate. I most often here people screwing up the discs and flywheel, but never toasting a pressure plate.
What I would do is clean the plate up with some sand paper and then examine it. Better yet, post a picture.

Well just to be sure Brain, here are some pictures:
I can still feel the striations in the plate as well.
When does a pressure plate normally wear out or go bad? I already have new bearings, so if I just need a plate, I'll order one from Hi Im Simon's ACT vendor buddy.

call ACT and ask them how much force it takes to lift the friction surface when the diaphragm is pushed down new...then take the PP to a shop with a press that can measure the load....measure and compare

Oh. I can barely get parts to the machine shop around my work schedule, much less find a place during normal business hours that can do that. Especially around here in BFE.

I'd just scratch it up and run it. It's not rocket science really. I'd get some 80 grit sand paper or so and scuff it up till it's clean metal. You don't want it dead slick or it won't cut into the new friction disk and break in. Same reason you hone an engine block.
As said, sandpaper on a flat surface is your best bet. A small 1" piece of glass works great if you happen to have something like this, as it's dead flat, very rigid, and will allow you to literally "surface" it pretty damn flat. I've surfaced small cylinder heads for small engines (go carts, outboards, etc) using this method. Very easy to get into factory spec.

Get s scotchbright pad from the kitchen. Your mom, girl, or roomate will never know it is gone. I wouldn't use anything heavy. Mine came off easy with the green pad, and there won't be any scratches to wear on your disc.
It is broke sell it to me cheap!
Quit thinking and install it. It is in perfect shape. Those pressure plates last forever. Those shiny spots on the teeth are normal. And will happen the first time you push the clutch in.
Seriously though, if you don't trust it, PM me. But I would use it if I was you.
Good Luck!
