Whilst tightening the pressure plate did you hear a clunk or bang at any point?

[serek]

did you use SAC tool when fitting clutch?

Problem Solved !

Turned out to be the Pressure Plate/Clutch Cover that was faulty ! Forks/Fingers were to tight to the circle piece behind the forks on the pressure plate making it to have no resistance to spring back when fully tightened to flywheel ! Got a new one the next day and all was perfect ! Defiantly a mind puzzler from the start but no it explains all. Hope this is good help to some.

Well done! When I changed mine I could not work out how the pressure plate worked. Are those long radial fingers merely levers, or are they springs? Which springs hold the clutch engaged while driving? I could see other springs lurking within the pressure plate, and steel wires. Is there an exploded diagram somewhere that would enlighten me?

It is a usual problem that the pressure plate fingers / forks are not even and level all around the centre ,so when you dip the clutch peddle to make the release bearing go against those fingers / forks,to lift the clutch away from the flywheel to stop it driving it will either judder or maybe not engage the gears at all......so always check  those before fitting and when fitted check them again as they all should look even.

Those fingers are one end of a diaphragm spring - that's the spring that holds the clutch in place and the same spring you must overcome to disengage the clutch when the release bearing pushes on the inner ends of the fingers..

There's a nice diagram here: http://auto.howstuffworks.com/clutch1.htm
And a very technical document on diaphragm springs here: http://www.haussermann.com/pub/pdf/en/tellerfeder.pdf
