[TowerTalk] Rohn TB3 questions

I have a TB3 on a tower that has been up about 6-7 years. The stainless 
steel bolts look bad. I have not tried to remove them though I want to 
change them out and apply some kind of anti-seize. IS there any BEST method 
of removing these bolts from a bearing in use on the tower?  - Mike

>  Removed the 3 tightning bolts as they were rusty. If I get  stainless to
replace I'm guessing they would gall. How abt the 'green' ones.  The
higher grade bolts?

    Any hardware the same size is fine. They are  very beefy for the job
they're asked to do.

>  Do the bearing get lubed? It spins freely now. I did clean  they out as
there was a bit if grime in the race.

    Do not lube the TB - it's designed to run dry. If  you do put grease in
there, it'll just collect dirt and grit and decrease the  service life of
the bearing.

    A new TB will spin freely. A good used one will  spin also but may be
rough due to wind hammering the ball bearings into the  aluminum races.
