Crank Pulley / Harmonic Balancer
I am replacing timing gears/timing chain on a 72 chevy covette, 350.
I am trying to remove the crank pulley and have removed the 3 small bolts holding it in place. The pulley does not seem to want to come off. I tried using a puller, but I dont want to force it too much for fear of breaking it. My question is... does the center bolt have a role in retaining the crank pulleys on the shaft? Or should I go ahead and pull-pull with the puller before removing the crank bolt?
At this time I am leaning towards removing the crank bolt to see what happens, hopefully freeing the pulley, reinstalling the bolt to bring the engine to TDC, then removing the harmonic balancer. Or should remove the balancer before going to TDC?
Thanks in advance!
