Tony,
I would not trust that small bolt to hold up the mast while working under it
(on the rotor) I use a muffler type U bolt above the thrust bearing to
secure the mast.
Good luck

Subject: [TowerTalk] Rotator Swap U.S. Tower Crank-Up
All:
Not sure if this is the proper procedure, but the last time I replaced a
Yaesu rotator on my U.S. Tower heavy-duty crank-up, I used the bolt that's
built into the tower to hold the mast in place to kept it from from falling.
It seemed to hold 100lbs of antennas just fine, but was wondering if I
should clamp the mast at the top above the bearing for a bit of insurance.
Tony
