Well Chris, thank you for pointing that out. You are talking about the
crankshaft locking tool VAG 3242. The correct torque is 148 ft. lbs. (or
200 Nm) plus a 180 degree turn. What is most important is that you do not
reuse the bolt. It is a one time use because that last 180 degrees actually
stretches the bolt slightly. This also happens with the head studs. Torque
specs must be followed on Audi engines otherwise they will shear or break.
But when removing the bolt, while the recommended thing is to use the lock
and a break-over bar (it better be a long one because that bolt is tough)
you can use the impact wrench. It is quicker, easier, and you don’t need
the lock. Even most well seasoned Audi mechanics are using impact wrenches.
It doesn’t harm the engine in any way, and I have put 20,000 miles on the
car since the repairs. Yes, it has been a busy year. I appreciate your
concern. As with most everything, there is more than one way to get a job
done.
ummm, not to rain on your parade, but what you do is use the audi tool
which holds your harmonic balancer fixed thus allowing one to loosen the
crank bolt by breaker bar. Thats what the designers at Audi said to do,
but you can do your own thing
