This is actually my first encounter… heated with MAP gas and 3ft breaker bar. What do I do?! This is an FX-1 pump so I’m trying to salvage what I can. Unfortunately this impeller wasn’t bad before it spread out, just an old Skat-Trak 19-24 but take a look at my tool and the impeller… HELP!

Righty loosey, Lefty tighty?

I would weld something to the impeller to get ahold of it to turn. If you do it nicely you could probably even salvage the impeller. Then heat it a lot and then heat it more.

Yep, it’s left hand thread like normal so I was pushing the correct direction for removal. Yeah I bet welding a large nut to it would be a good option! Unfortunately the inside of the impeller is pretty much stripped so I don’t know how much salvaging there will be

I just did this which, unknowingly, what @mikesx recommended.

Heat it hot. Spray PB Blaster into it.
Repeat.
Repeat.
Leave it alone and the next day it will come off easy peasy.

I actually might have a sample bearing you could just have laying in the tool box yet

I have also had luck with heating, allowing to cool, then heating again, and repeating.

I had a wavejammer that ate rocks in a prior life, I took a skinny wheel and sliced it up to remove it from the shaft, but it was a soft aluminum one, might take quite a few wheels to get though that stainless one.
