I use a TB3 with my 2" 4130 mast. It slipped in fine. You don't do anything
to the TB3.

Subject: [TowerTalk] Rohn TB? info
Hey all!
I'm curious about the Rohn TB? thrust bearing (2"
model):
1. How tight is the 2" fit? I have two 4130 masts (2"
ID, 1/4" wall) and both a 'slightly' bigger than 2".
I had to go to a 55mm bearing on the first.
2. What sort of weather resistence does it have? Galv?
What are people doing to help this when installed?
Thanks es 73!
