[Milsurplus] art13 ballentine dynamotor

[Michael Hanz]

You have one of the later contract dynos that have sealed bearings, 
Jeff.  They should be fine without trying to get oil into them. They are 
designed to be replaced when they go bad, and the seals do a pretty good 
job of keeping brush dust out and cut the rate of light oil evaporation 
to almost nothing.
