  Of course remember the actual size of the bolt is the diameter 
of the bolt and not the size of the head as we'll often refer to

  An impact wrench tends to need less holding than straight torque 
since you're hammering the bolt in tight rather than a constant 
pull up to the necessary torque.  Unlikely you'll strip teeth so long 
as you hold the flywheel firmly.  The catch is to hold it so it doesn't 
move around.  Usually takes a second person.
