I built a tool for my wheel puller - have turned it to about 80 ft/lbs, kinda worried to crank it another turn,,,,,,

I am using penetrating oil on the shaft,,,,,,,,,what next?

Heat?

Incantations?

Ideas?

Sort of depends on your budget. If money is no object, I'd say get an OxyAcetylene rig - even if only one of the really small portable ones plumbers use. Sometimes I wonder how I ever lived without the fire wrench. But then you're screwed trying to get cylinders filled on a Sunday.


The MAPP / Oxy set up is sort of the middle ground but comes with its own disadvantages. Costly to operate (an oxygen cyclinder doesn't last long), not great for welding due to higher hydrogen content that can lead to hydrogen embrittlement.


Similarly, on the budget conscious end, MAPP gas only is a good upgrade to propane. If you heat it with MAPP gas, have some tension on it, and use the dual hammer technique or air hammer as suggested above that is a reasonable approach.

Since your just in the middle and trying to get it done, I think starting with MAPP only is a reasonable approach.
