Questions about checking SAC zero position

[sCeRaXn]

I have a Vast RS4 clutch with upgraded organic disk that im hoping to put in this weekend. Ive read that the SAC mechanism has caused problems on a few stock and RS4 based clutches. I want to try and avoid having to do this again in the hear future, so how do i go about checking the SAC for zero position(as vast recommends on their site)? Is there a write-up or DIY on this procedure? I searched on here and got basically nothing, and i tried audiworld but i got tired of searching after page 17 lol. Maybe i just suck with the search feature or something.

Any help would be appreciated.

BTW-While im here i might as well ask...what are the tq specs for the fw/crank and clutch/fw bolts? Also, since theyre TTY, have you been torqueing them in steps or going straight to the final tq? Thanks in advance.

When set correctly, the SAC mechanism should look like this (note the fully compressed spring and the little metal tabs visible in the slots):
Here's a writeup for you:
SAC setting writeup

Here are your torque specs: FW to crank - 60 Nm, then another 180 °
PP to FW - 22nm
Torque all bolts in a star pattern and do so in several stages (tighten each bolt numerous times until you reach the torque spec).

Thanks Jordan. I just read the writeup and went and checked my PP, and it was out of adjustment...which isnt a suprise considering the way everything else has gone with this car lol. I guess ill be taking it to a friends shop to use their press to adjust it. Im glad i caught it before i put it in though...you just saved me alot of cussing and free time lol. Thanks again man.
