CP3 pulley removal

[packnheat]

I need to remove the pulley from the cp3 pump. Anyone know what size bolts go in the pulley? I'm actually just breaking the pulley loose from the shaft while on the truck. Then I will rotate in 30 degree increments to hopefully cure a harmonic detonation like sound that I have. Any help??
