Mark,
How about the idea of wrapping the mast and then rig a come-along or a lever
jack over the top of the tower to get the weight off?
If you could also drill a bolt hole in the bottom area of the mast and slide
a bolt through it if you can't get enough friction.
The key may be to lift from two sides at once in order not to bind.

Subject: [TowerTalk] rotor removal question
Hello Everyone,
I had a problem changing out my rotor today. Its a rd1800 rotor on a rohn
ssv tower. The 2inch mast has slid down farther on top of the rotor mount
and
Im unable to remove the rotor now(cant slide it out to replace). Im looking
for advice on how to lift up the mast maybe an inch, considering the rd1800
is
still underneath the mast. The mast and antenna weigh about 200lbs and Im
unable to lift it w/o some assistance. The only support I have for the
mast is
the thrust bearing(should have put another plate or support inbetween) on
top
of the tower. Im considering trying to attach some clamp or bar metal to
the
mast and use a car jack or something to push the mast back up to get the
rotor out. Tower is 80ft and Id like to do it right the first time. Any
ideas on
how to jack the mast back up? Thankyou.
