HI, is it possible to ruin new crank bearings with a propane torch? Holding the flame at a distance and all of a sudden see the oil coating poof into a flash of flame, installed and nothing added. Never became discolored or purposely try to heat it too fast. The crank is centered but wondering...

Is it a common issue to ruin a crankshaft on a chainsaw? ex: the crank bends and now the saw his higher resistance and wont start? Just a slight tweak, not from a chain getting too hot and shrinking but from use? My 372xp has issues and cant put a finger on it, seems to be bottom end failure...
