[R-390] How NOT to lubricate R390A gear train

[rbethman]

Tisha,

The basic issue is the lack of education regarding gears and how they 
really work.

Mounting points, and the gear teeth are about all you need to lube.  
Certainly NOT with lithium grease!  All it will do is attract dust and 
crud over time.

Hope Perry gets his scale soon.
