I have some questions about lubricating motors.  What I have read
indicates that you would use oil in a lubrication holder with a wick
and use grease if the motor has grease cups.

I am working on a Wurlitzer motor that has cast lubrication holders
above the motor shafts.  There are caps on them and a stiff wire with a
loop at the top extending through a hole in the cap down through a hole
at the bottom of the lubrication holder, to touch the motor shaft.
Currently, there is nothing in these lubrication holders except what
appears to be a film of grease.

My questions are:

1. What does a grease cup look like?
2. Are what I described grease cups?
3. If they are, what kind of grease is used?  Special electric motor
   grease?
4. If not, are the wicks missing?

I have another Wurlitzer motor that has screw on lubrication holders
below the motor shaft with spring loaded wicks.  I used 30 weight oil
to saturate the wicking at the bottom of the holders.  Is this the
correct lubricant?

Thanks,

Jack Niewoehner
