Sticky bolts

Trying to drop the leg so I can change the impellor. Trouble is there is one bolt that wont shift and is threatening to really make my day and snap off. Any sugestions as to how to loosen or ease it?

Have tried WD40 so dont sugest that one!
Was wondering if limescale remover would help.

Cheers
Tim'mers.

bolt

Depending on which bolt it is, put some heat on it. before trying to turn it give it a bit of a tap with hammer puch/another bolt as the shock and heat sometimes gets the shifted.
If it shifts then reheat and go again

Ah that is normally salt corrsion holding bolt in around body and not normally in the threads.
Heat iand tap it. Put some heat on the top as well.
It takes alot to melt the real merc paint

Cheers for that Paul.
May sound a bone question but how much heat should I give it, I mean is it a gentle warming or a good blast till it goes blue.

Also should it be hot when I try to move it or should I let it cool down. Never tried heating stainless / ally.

Swifty,

Have you tried tightening the bolt very slightly?
Although it may trash the paint try heating around the bolt, this will expand the hole not the bolt if done quickly enough.

bolts

Start with gentle heat and progress on till it moves it will normally shift before paint melts.Move heat around and not just in one spot.Once it starts to move dont let it cool down to much as it will become tight again.
