Chuckie - you have no idea how precise your advice was for this.  I have exactly one of those Ryobi cordless hammer drills that I haven't used in years.  Had to charge the battery for about 1-1.5hrs then went to work on both motors.  Got the broken actuator removed and working, non-stuck actuators installed with new bushings in both motors in no time at all.  All it took was a quick 1/2 second bump of the drill to pop em loose.  Easy as could be. 
On the motor that didn't have the broken actuator, when I removed it I found a nice 1/8 inch piece of broken metal hiding out back there.  I can't quite tell if it's a piece of former thrust washer or a small chunk of case.  It's rounded but looks to be a little too tight of a circle to be a thrust washer.  Couldn't find any obvious breaks anywhere so who knows where it came from. 

Thanks again for the advice.  Here are a couple new pics showing the spare re-installed with a full range of motion:
