Harmonic balancer bolt removal

[RyanG]

I went to the FAQ section and typed in Harmonic as the search word and nothing came up. Any way here is my situation. I pulled the motor out of my truck and put the new on in. The new one is all bolted up and the old one is on a stand. I don't know how to remove the harmonic balancer bolt to get my pulleys off the old one. Can anyone offer any suggestions. I don't have acces to air at this time. Also there is no flywheel on the old one.
