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.
