Geoff,
It is possible that a small amount of moisture entered the bearings.
The bearing are sealed on one side only, the side facing the end bells
of the converter is open and the grease is located there. It is not
hard to remove the end bells and repack the bearings. However, don't
over grease them. Many people think that if a little grease is good,
then more is better. Not true don't do it. Just remove the end bells
unbolt and knock loose with a dead-blow hammer. Carefully remove the
rotor making sure that no damage occures to the windings. The bearings
will remain located on the rotor. Rince them clean with WD-40 and dry
with compressed air. Then repac the bearings with a good quality
general purpose grease. Remember there is very little load applied to
this motor and it seldom gets to hot, so a light viscosity grease will
flow better at low temps. Place about two tablespoons of grease in the
end bell cavities.
Reassemble and retighten the end bell bolts.
Try it again it should sound better.
Let me know how it goes.

Hi all,
When I start up my Kay MA-1 Phasemaster, it sounds like it has bad
bearings
(whining) until it warms up a bit. This unit was never used, but sat
for two
years on its pallet before I purchased it with the BF6-31 and AF-22
from
Mike Simpson in Oregon.
Does this model have grease fittings? Should I go get a grease gun
and the
recommended lubricant (Chevron SRI) and try lubing up the bearings?
Or do
they all do this?
The temp in my shop these days is about 60F give or take.
Also - thanks to Felder USA for footing the bill on the "No Ads"
