@crank bearings

I’ve just replaced the crankcase bearings in my Husqvarna 61 and after reassembling the crank case, found the crankshaft difficult to turn, even with the cylinder head off. I’m a complete novice, but thought the crankshaft should spin freely with new bearings. Any advice would be appreciated

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...
