Ron,

Check with a farm supply such as Tractor Supply or even a good local
hardware for grease which works well at low temps. Lithium grease is
good, both for that and for general use. I am in a moderate climate,


I use a PST-63 turning a large array. I drained out the gear lube and
packed the thing full of white Lithium grease. Works just fine down
into sub zero temps although it's rare to see below zero around here
now days.

but those who live in extremes report it does the job. This topic
comes up on bulletin board I subscribe to, and this is a recent
comment from someone who would probably regard New England winters are
balmy.

================================================= ============
Having often operated from the eastern part of Norway for many years
with as daily temperature of minus 35 degrees in February - I have a
little 'experience' from cold climates.

The long term solution is to change the grease to one that can
tolerate the temperature and to mount a "motor warmer".

I used the heating element from a kettle. It keeps the rotor nice and
warm in the winter ... but increases your electricity bill ...
horses for courses ...
