Does it require a wheel puller to remove it? The FSM says yes. Youtube says no. I have rebuilt Buick engines. 215, 300, 350, 401, 430, 455 some of these examples more than once. And outside of this, I have had to remove harmonic balancers on several more. I have NEVER needed a puller on any of these engines. Remove the bolt, tap the balancer once or twice and they slide right off.

All Ford and Chevy engines I have worked on require a puller almost ALL THE WAY until it falls off the end. The Ford Thunderbird 312 is the biggest PITA.

I understand the 3800 series II and III need a puller. And the pre-series I does NOT (the 1988-90 Reattas for example).

So, before I dig in, does anyone know FOR SURE, WITH EXPERIENCE (I mean no guessing please) if the 3800 Series I needs a puller or not? Thank you!
