Title: Scratch in pressure plate surface
Post by: JamesV6CDX on 02 June 2014, 20:15:37
New clutch kit is at home, just inspecting it

Seems to be a scratch, just about detectable by a fingernail, on the pressure plate surface as per pics

Ok to fit? Or likely to damage friction plate?

To get a new one tomorrow would be a massive ballache :(

can't see your picture, but if it's only detectable by finger nail just fit it. Friction plate will soon  make its own marks.  ;)

I have to disagree  ::) I

In a perfect world, you're correct, but as it's only just detectable etc etc ........ I'd fit it (but I wouldn't have  car with a clutch anyway  ;D)

Just need to satisfy myself it's a small scratch, not a crack! Don't want a chunk breaking off!

Neither do I.

If its just a scratch - fit it James, shouldn't cause any issues ;)

Also re pressure plate

Three of the diaphragm parts on the plate sit much lower than the others. See pic.
Is this normal for a new sac clutch?

The three that are lower are directly under some sort of spring. Guessing part of the adjustment process

Anyone confirm please? I'd like to get this done tomorrow :y

Presumably your installation tool will push the other twelve prongs down to the same level as you tighten it down :-\

I hope so but why are the three prongs under the spring arms so far down?

On all pics of new sac clutch pressure plates online they are all equal :(

Any doubts, take it back...

Post by: JamesV6CDX on 02 June 2014, 22:23:07
Look at the pic. I've just read the spring pushes the mechanism clockwise as the clutch wears, to compensate

Mine is as far clockwise as it can go, no?

Hence shagged?

How can this be from new??

HELP !! ;D

Any instructions regarding the two arrows next to the plastic tab/coil spring :-\

Perhaps you have to wind it back on fitting .. or it goes back as you tighten it down evenly .. ??

pages 12  & 13 .. talk about turning the spindle to relieve the spring  ??

page 25 might be useful .. if you go to the product site ??

I was just reading the same PDF .. I was going to say the same thing - does the tool effectively 'set up' the adjuster?

Not sure though - I read it and my brain still can't quite figure out how it works..

Being self adjusting and all, you'd have thought it would adjust itself :-\

Go figure ::)

I figure I want a good old fashioned clutch which my old man (god rest his soul) taught me to fit with nothing more specialist than a spanner and a broom handle!!!! ;D

Serek, you seem to know a bit about these, any thoughts on the last? :y

Wonder if its been sent back as wrong type and the supplier has sent it out again and not realised its no good to fit  :y

Just spoke to LUK directly, very helpful chap, talked through it and he assures me it's fine and ready to fit :y

When you do it you'll have to try and describe to us what happens, etc.. :)

The setup is nothing more than an extra ring with a ramped pivot for the release springs, the extra ring has a small spring to apply a load to make it rotate, it is supplied in the zero wear positon, the tool does nothing to set the system.

The issue is that if you clamp the pressure plate down unevenly then the sensor spring can get fooled into thinking there is friction plate wear and the extra ring rotates and alters the pivot point.

Hence, progressive tightening of the pressure plate to flywheel is the alterntive.

All the tool does is make it idiot proof (to suit the average mechanic  ;D :y) by compressing all the release springs at the same time.

there always alternative  :y
but from my point if I use right tool for job save time and money
is same when you fit timing belt can be done with out locking tool  ::)

Oh no.. now you've gone and done it! ;D

P.S. Mark - nice description  :y Oddly enough the LuK site makes it sound much fancier and more complicated than that ;D Still I suppose I'll get the chance to play with one (the old one!) when/if I do the clutch on the M3. Maybe then I'll properly understand :-[

The key thing is though Serek that the V6 timing tool is required to set the timing, there is nothing with the SAC clutch tool that sets anything up.

For yourself where you may be doing this very regularly then yes, a worthwhile investment (Would make the job quicker) but for the DIY man/woman, its something of a luxury. :y
