For a K7M engine:

Please can someone more experienced give me their impression on this torque setting for the crank-pulley bolt:

30nm +100 +-5degrees

I got this from the K7M Timing Belt instruction set. Just want to make sure. (For the imperial members 30nm = 22.12686ft-lb )

Yes, that seems reasonable. Be sure you are NOT re-using the original bolt. When used like this, called "torque-to-yield" the fastener has been stretched beyond its deformation limit and if re-used, it will not torque properly and may break.

Be careful about the angle, it's important!

So to do this you torque to 30 Nm, then rotate it an additional 100 degrees of rotation with a tolerance of +/- 5 degrees.
