you MUST not torque up using the belt method, you are putting the full force of the torque against the woodruff key on the pulley which is only a cast piece, you will sheer this and destroy your engine.... the workshop manual and how MJ does it is correct.
The factory way of holding the crank whether V8, V6 or inline 5 are the only way to do the belts...
