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.

 

I will post a picture as soon as I get a chance to!

 

PP is fine order a new disc from carolina clutch.

 

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.

 

lightly scuff that bitch with some sandpaper
install new disc
?????
profit

 

Yeah yeah yeah, I know your opinion already. lol I told you I was going to post this.

 

right, but I added profit

 

Very true.

 

I want to do this when I swap motors...go from a street disc to a 6 puck to hold a bit of extra power, but still save weight and about 300 bucks.

 

Is there any particular grit sandpaper I should use? Any particular method (besides lightly scuffing)? Basically what should the end result be?

 

ive used like 150 grit and a small block, seemed to work fine. The scratches will be removed in a few hundred miles

 

use a ScotchBrite pad.

 

Cool. So just because I want to know, other than worn out fingers or a messed up plate, is there anything else that makes a pressure plate "worn out"?

 

There's nothing else to it. I think that would be it.

 

should I expect to be able to reuse a pressure plate when you have a metal clutch disk?

 

I've seen the fingers wear, or bend. Also seen the friction surface be worn to the point that the rivets on the disk hit the friction instead of the disks' frictions, causing it to pretty much not work. Or a warped friction, or glazzed over surface.

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!
