[R-390] R-390 (Non-A) RF Gears Cleaning

[Alex Hopper]

Hi All,

I have done quite a bit of reading on the best ways to clean the RF deck
gear train on the R-390.  Seems that most people recommend a thorough flush
of WD-40.

Does anyone have personal experience with this?  I am tempted to try it,
however I am NOT interested in removing my RF Module.  Is this something I
can carefully do with the RF module still intact?  I would use a long
'staw' aimed down carefully into the gears.
