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
