Help!! Crankshaft pulley problem
I have an 86 IROC with the 305 TPI. I am trying to remove the crankshaft pulley but can't figure it out. It has 3 bolts which I unscrewed but the pulley will not budge. There is a bolt in the center of the pulley but I think it is for the balancer..?? Do I need to unscrew that middle bolt to get the pulley off. Any help would be great.

Penetrating oil and a hammer! Be careful not to bend it...

I don't really recall... but, i don't think you need to. Of course, it wouldn't hurt to take it out, and see if that makes the difference.
