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
