How to pull Chevy GMC LS 5.3 4.8 6.0 crankshaft pulley / harmonic balancer

Quick video to show myself which 3 jaw puller to use. If you're wondering how to remove the big crank bolt, pin a long breaker bar against the driver's side frame rail and hit the starter.to break it loose. It is torqued to 250 ft lbs and cannot be removed otherwise unless you have a really powerful impact gun.
