Yes I use a harmonic balancer puller as well.
My 3/4" drive rattle/impact gun has a maximum torque of 1215 ft-lbs so would wreck a flywheel in seconds! And yes I've had jobs on earthmoving equipment that I really need a bigger one but got away with a bar welded to the nut & 2ft of railway line sitting on top plus a 20kg sledge hammer. Still it took 2 weeks to get 4 rusted bolts out!
I think it was Tecumseh that used a pry bar under the flywheel & an adaptor to protect the thread whilst hitting the crank. I'm not keen on that method either...
