Nice thread Matt.
I do crankcase&crank a bit different on those saws who has seal in PTO bearing.
I mount PTO bearing on crank first and place it in the freezer, heating up the case half to about 130° celsius, it slide straight down with those temperature diffences.
Dumping the whole thing a few minute in freezer again to help cooling fast down again.
Doing gasket and all those things on PTO side.
Flywheel side is 200° celsius, it's the temperature I feel I can reach to mount bearing and have enough heat transfered to the bearing for sliding everything together without torquing it together with screws.
This is what have worked best out for me, it doesnt need to be the best way for others
