I took the powerhead off about 1 yr ago, and at the time new the bolts where only just moving with out snapping.
Today I have been trying to get them out ,but I cant get them out. Some of them move ok but wont pull out but 2 are only moving very slightly (when i hit them with a big hammer)

Ideas on getting these out please

Get an oxy acetelene torch and heat up the areas that they run through. This will expand the aluminum and not the steel of the bolts, or not so fast anyway. Use grease when you put them back in.
