Harmonic Balancer Removal

Guys, this will be my first harmonic balancer removal on one of my old Mopars...........never had cause to change one before.

Is there ANYTHING in particular I need to know about these things before I attempt it ?

I have everything out of the way, and the 1-1/8" main retaining bolt is out...ready for a puller.......any specific type of puller recommended ? Any common problems with the 70 Mopars coming off or going back on that I should know of ?

I'm not gonna' proceed until I hear back.......................

Thanks.......... Doc :coffee2:
