Can I simply loosen the mast clamp and lower the antenna to rest on the thrust bearing then loosen the rotor clamp to slide the mast up to remove the rotor. What would be the easiest process to switch out a rotor without removing the antenna. Thanks in advance guys. Have a great memorial weekend guys.

I've been doing this for years and it's with a large array 
http://www.rogerhalstead.com/ham_files/Tower29.htm (link posted many 
times before).  There are two thrust bearings that normally only support 
the system from side to side movement. To take out the rotator I raise 
the antennas and mast a few inches and tighten the bolts in the bottom 
thrust bearing to hold things in place. (The system is heavy enough I 
put a clamp and clevis on the mast and use a "come-along" to raise it).  
Once raised I simply take the rotator out the side of the tower.  Note 
rotator motor sticks out the side of the tower to the left, just above 
the bottom of the photo.
