I use the toaster oven too. Give it a good overnight soak with plenty of the
Knock-er-loose. Then I flick some spit on the part to see if it's hot enough.

When the "spit dances" (boils) it's good and hot. The solvent will be smoking
and stinking up a storm, so the garage is the place to do the deed. Whack the
crankcase down flat and hard on a board till the bearing comes out.

Good luck
