It is not hard at all. I have had this same setup for 11 years on my Rohn
tower. I have replaced the rotator on the 17 foot mast on three occasions
(well, the tower guys did it). It is hard for me to imagine how difficult
the replacement of the rotator would be if I didn't have those two bearings
in place. I bought a second rotator and took the rotator and the bearing to
a machine shop and they put the proper holes in the plate and made sure that
they lined up. "no problem". I'll send you a separate e-mail with a picture.

Subject: Re: [TowerTalk] Rohn 45 Bearing Plate
I'm planning to do something like this.
I plan only one thrust bearing, at the top, but I plan a second rotator
plate (I'm ordering from Custom Metalworks), with a hole slightly larger
than the mast, mounted about a foot above the "real" rotator plate. This
gives me something to clamp the mast to so that I can remove the rotator for
service. I have to get the hole is just large enough to clear the mast, but
indeed completely clear the mast in normal use.
I suspect that getting two thrust bearings to line up exactly might be a
difficult task.

Subject: [TowerTalk] Rohn 45 Bearing Plate
I am using Rohn 45 and want to put a second thrust bearing between the
rotator and mast. The bearing plate p/n BPL45G can only be mounted at the
top. Is there any way of putting a second bearing plate between the rotator
and the the top baring plate?
Thanks in advance!
