[R-390] Lubrication

[Rick Brashear]

Hi all,

I finally own my first R-390 (non A) and need advice about a few 
things.  The "Kilocycle Change" seems to me (remember, this is the first 
one I have ever turned) to be a little stiff or maybe better described 
as hesitant.  I reset the bushing where the shaft enters the front panel 
and that seemed to help considerably, but it still is not silky smooth.  
The receiver is not real dirty and works relatively well, however, the 
gear mechanism may be in need of cleaning and lubricating.  What is the 
best cleaner and lubricant to use in this area?  And, what are the 
pitfalls I should be aware of before tackling this task?  I know it will 
need further work and alignment, but on the advice of a friend I want to 
be sure I am not damaging anything due to the stiff tuning first.

Thanks for any and all advise you may offer.
