Re: [TowerTalk] Re: Thrust Bearing Usage

[Doug Renwick <ve5ra@sasktel.net>]

My experience differs...properly sized thrust bearing side screws ARE used
to support the weight of the mast and antennas at my QTH.  I have not had
any adverse reactions from using this method and it certainly simplifies
the process when having to change out a rotor.  Care must be taken when
using the words "never" and "always".

  So both are sharing the loads.  Also, the thrust bearing side screws are only
  used to center the mast in the bearing; they are never used to hold the weight
  of the assembly.  To change out the rotator I'll either use a come-a-long 
inside
  of the tower and jack up the mast or use a scissors jack on the top plate and
  jack up against the antenna boom to mast plate.  Gd luck, Phil  KB9CRY
