tin top clutch advice
I am in the prosses of replacing the dualmass flywheel and clutch on my VW Bora . Now i have bought Luk components for both and on fitting the
friction plate and pressure plate i noticed that there was about 5mm of gap to pull up while tightening the pressure plate bolts. Now the bolts are
fully tight the fingers on the pressure plate have been forced inward to the point that they nearly touch the friction plate.
Is this normal as i have no experience of fitting clutches.
Thanks in advance
brad.

Could the clutch plate be the wrong way round?

Is it a self adjusting clutch?SAC
If knocked or dropped they can pre-release and that causes the fault you describe. My money would be on the plate fitted the wrong way around
(it'll say either gearbox or flywheel side on it)

It is a sacs clutch, and the friction plate is the right way round as it says gearbox side on it.
Exactly how does the clutch work, i cant see any mechanism for releasing the clutch at all. The flywheel is bolted to the crank then the clutch plate
is trapped between the flywheel and pressure plate, but the pressure plate is bolted to the flywheel. The input shaft from the gearbox has a sprung
loaded bearing and that is all.

SACS is in the clutch cover/presure plate. Between the diaphragm and the cover there is a ring with a series of ramps on it and corresponding ramps on
the cover. As the driven plate wears the ring rotates, pulled by springs and moves up ramps, taking up the play and keeping the diaphragm fingers
level. This results in the clutch presure remaining consistent throughout its life. There are some marks on the ring if you know where to look that
tell whether it's released... but not easy to describe. There's also a tool to retain the adjuster while fitting, but it's not
essential, just safer to use. I bought one and have never used it.

ps. probably a very poor description.

I will have a look at it tomorrow to see if it has been sprung.
I have just seen a video of how the pressure plate works, and in its current state , mine will not work at all.
