Hi
Going to change the clutch on my car and will most probably need to remove the flywheel for a resurface.

What size of XNZ tool is it to remove flywheel bolts ?
It's a 964 turbo 1991.

Um you are not supposed to resurface flywheels especially double mass ones. You will throw it out of balance for and you may do further damage to the secondary mass.
If you have a single mass flywheel I would still not recommend resurfacing it.
There are no laid down tolerances that I am aware of for this which tends to suggest that it is not a good idea.
Ciao,

Check out www.zdmak.com for the sockets. That's where I got mine from.

Adrian raises an excellent point, as usual Given that the friction surface is not mated directly to the flywheel mounting side, other than via rubber, I wouldnt attempt any resurfacing process. Given the amount of work required to get to the flywheel, this would be too risky IMHO..

Staffan,
I re-read your original question. The clutch cover is a #8 XZN and the flywheel is a #10.

Hmmm, check this out:

The say:
NOTE: We recommend you have the flywheel resurfaced
On page 2, again:
Every time you replace your clutch, you should replace your flywheel with a good resurfaced one or a brand new one.

This is a completly new field for me.
Don't know how the double mass flywheel works.

Actually this whole discussion makes me a bit worried.
Is it easy to ruin the flywheel ?
I was thinking about getting the RS Clutch kit, but decided to just replace the clutch with a stock one and keep the flywheel. So that's what I ordered. If the flywheel is gone and can't be resurfaced I am going to

If that is the case I made a huge mistake.
A new flywheel is very very expensive!

You can buy a genuine LWF from Porsche (in the USA) for around $400USD but I don't think you will be able to use your new solid centered clutch with it.
