Is it normal for the drive shaft to move in an out by half an inch??

I replaced the pulley on my driveshaft with a larger one so my alternator would spin faster at low RPMs. During the process, I noticed that my driveshaft moves in and out about 1/4 to 1/2 inch. is that OK or should it not do that? I wonder if I caused it to do that when I was trying to pry the old pulley off with a screw driver? I am guessing I put about 50 pounds of pressure on it. I finally gave up, got a wheel puller and removed it.

When I first started the engine with the new pulley. I noticed that it was rubbing on the engine slightly, but i was able to stop that by pulling the drive shaft away from the engine. I am concerned that it might move back again, so I re-set the pulley on the drive shaft 1/4 of an inch further away from the engine.
Should I be concerned about the movement in the drive shaft and if so, what can I do about it?

Thanks for your help.
