When I replaced my main bearings, I dropped the crankshaft a fair amount. I found out that if I didn't let it down evenly it would hang up on the thrust bearing. Also it can damage the front seal but in my case I had the cover off. I also had to check that the timing marks were aligned when I pulled it back up into place. You shouldn't have to drop it that much.
