Hi Ron,
Yes, mine had the same problem and have a few suggestions, first, though,
check the alignment of the rotor to the coupling to the thrust bearing
assembly. My rotor was turning with a little bit of list and as a result,
it would bind. You might be surprised that the binding might be below the
thrust bearing, not above. I've worked with mine for years and I love it...

Subject: [Bulk] [TowerTalk] MA550 Tubular Tower Binding.
Hello All,
I have installed a US Towers MA-550 Tubular tower with the free standing
rotor base. I made sure the tower is plum. Connecting the rotor assembly has
gone well.
After all of that, the tower experiences binding. I have rechecked the tower
for being plum and that the rotor is lined up as best as I can. The tower
will swing 270 +/- and then stop. I can go the other way without any
stoppage.
After a closer look at the thrust bearing, I think I see that the tower race
may not be sitting flush on top of the bear. I do not know what the ring at
the base of the tower that has a allen set screw is for and I have not
messed with it.
Any ideas to fix this problem without taking down the antenna? (It is a
Force-12 C-4)
I think I know the answer to this, but I am looking for any information that
might help.
Thanks,
73
Ron
