[TowerTalk] rotor removal question

[EL34GUY at aol.com]

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.
