A6 2.8 V30 Crank bolt torque?
Hi, I'm in the middle of timing belt/seals replacement (the car is already apart) and I was stupid enough to start it without repair manual. =)
Can anyone please check in your books what torque must be used for the crank and cam bolts, and how does the crank bolt must be removed (will putting the car in gear and holding brakes be enough?)
Thanks.

From the Bentley -
Toothed belt sprocket to camshaft
Idler wheel
Toothed belt tensioning roller
Pulley to crankshaft
Toothed belt tensioner
Center bolt to crankshaft 1)
1) Always replace the center bolt.
2) The additional 1/2 -turn (180
) can also be tightened in two 1/4 -turn (90) steps.
