the other day, as I made the last corner coming home, at WOT I felt my clutch slipping. blipped the throttle a few more times to verify and sure enough, it was slipping.

so I stayed out of the secondaries for the last mile home, tore it open, and found this:

some bent fingers on the diaphram of the pressure plate, the ring that holds the weights is broken and part of it missing, and the weights were loose.

first question--why did this happen?

second question--can I fix the pressure plate, or is it toast?

Good news is that I felt it early enough and stayed out of it, so there's no blueing on the flywheel or on the pressure plate from getting too hot.

I recovered all the weights...can they be put back on? what about those 3 or 4 fingers on the pressure plate that are higher than the rest?

Diaphragm clutch repair is NOT a do-it-yourself project.......

Any chance the fingers hit the disc?

I've actually removed the weights from one diaphragm & swapped them to another. Straighten out one end of the retaining wire, remove wire, install weights and use a new similar guage wire. You can try to reuse the old wire but it might be too fatigued and snap after rebending in place.

No I don't think so, the disc even looks new still.

I know I'm outside of any warranty, but I thought I might call centerforce on this, to see what they say. this clutch has less than 1,000 miles on it, and the flywheel still looks new, the pressure plate still has it's machining marks on it, and the disc looks fairly new too.

I just wondered if it could be repaired...if it's not a do it yourself deal, that's ok, repairing the pressure plate, even paying a shop to do it, has got to be cheaper than buying a whole new one!

This ... take it to a local clutch rebuilder.

so it's fixable without having to buy a whole new pressure plate.

but...why'd it happen in the first place?

That I can not tell you, those bent fingers need to be fix , or replaced, it might be easier/cheaper just to buy a new plate and transfer the weights, If I remember right the PP is a LUK ...

I was told that with the centerforce dual friction the pressure plate and clutch are a matched pair and you have to replace both. Maybe not because yours is still so new...? Good luck, hopefully it's an easy fix instead.

The Centerforce dual friction I saw 1st hand was a LUK parts store pressure plate with the weights added.


Take care,

That's what they TELL you because they want maximum dollars and don't want to just sell discs . I got a dual friction disc from a local clutch rebuilding shop and used it with a used CF PP and it was fine .
