Hi!

So I Succeeded in testing some pressure plates. With my original pressure plate( this plate came loose once because I forgot loctite) the clutch wont fully disengage. Are there any adjustements possible on the pressure plate? Or is it just fubar?
I'd like to use the original flywheel because its probably balanced on the crank? I suppose I cant just fit a new pressure plate as it will need to be balanced too?
And a final question : is it normal for stock flywheels to have different weights? Got everything from 10 to 11 kilograms...

Cheers

What sort of clutch is it....

 

and, no things from the factory are not balanced to the crank... each item was individually balanced and then put together...

it is a Verto (or was last time he asked about it)

 

check the condition of the little ball on the end of the clutch lever.

 

sounds like you have more than one so comparison should be easy.

Sorry, I tried to weigh a few but by scales only go up to 5Kg 

 

Your were trying to test this outside the car weren't you? Assuming you ended up bolting it to an engine, did you set the clutch release adjuster? There should be a gap of 6.5mm between the adjuster nut and the wok cover. With the clutch fully open, does the nut touch the cover?

It ended up in a vice

Cool to see how the emchanism works by the way. 

But I saw a clear difference between the working and non working plate :/ The working made the friction plate release fully, while the non-working still kept the fricture plate in place/ not fully released

Verto pressure plate

If you used different flywheels for each pressure plate, then measure to see if someone has machined the posts down on one of them, to increase the clamping force.

 

 

I have Verto clutches from an SPI engine and a 998 engine and these parts have slight differences in the spring/back plate , centre hub, and the cup shaped part that pushes on the spring.  I always assumed they were fairly interchangeable, but you may need to start measuring parts, including the flywheels if it's still not obvious why they are different weights.

Well, it are the pressur eplates that weight different The flywheels themselves weight in fairly consistent ( approx 80 gramms of difference max)

The heavist plate does look a bit weard imo , with some kind of reinforcement ring around the 'fingers'
