I have a prop pitch motor and gearbox from an old Antenna Mart PP rotor
available. When I received the rotor, it was not operational & still in the
Antenna Mart cylindrical can. The upper flange bearing was rusted and
seized.
The PP is now free from the can & it runs, albeit noisily, in both
directions. The mast shaft is welded to the splined output. I separated the
output from the planetary gearbox; it still had oil in it. The seal is in
great shape.

$225 shipped, CONUS
I can deliver to the Cave City, KY hamfest on March 22, or the SVHFS
Conference in Clarksville, TN the first weekend in April.
Thanks,
Robin Midgett K4IDC
