> SECOND, penetrating oil and a pinpoint heat source are your friends.
> If you do not know them intimately, get to know them on a first name basis.
> It will serve you well.
> THIRD, LOW POWERED IMPACT TOOLS ARE YOUR FRIEND (or worst enemy,

> So, open the hatch and spray your most effective penetrating agent

> Put a 6 point closed end wrench on the bolt, pull the wrench and tap,
> tap, tap the end of the bolt with a hammer. If nothing budges, spray it
> liberally with penetrant and WALK AWAY. Come back tomorrow with determined
> resolve, and repeat the 6 point wrench trick. Try turning in both

> great deal.
> I have a battery powered 1/4 inch drive impact wrench. It will rattle
> the hell out of those bolts, without snapping them off. I also have a
> jeweler's oxy/acetylene torch with a tiny pinpoint flame that I use. Be
> very, very carefull with flames under the hatch. Have an assistant with
> lightning quick reactions and a cool head standing by with a CO2 or Halon
> extinguisher when you do this. Absolutely not a dry chemical one. Apply
> heat to the bolt and get it hot but not red hot. Then spray a couple of
> quick squirts of penetrating oil on it. It might flare up briefly and smoke
> like mad. Just blow it out with your breath, and apply the impact tricks
> again. Repeat. BE PATIENT, you only have a stuck bolt. If you yank on that
> wrench with too much force, you will set yourself up for a whole bunch of
> work.
