[Drake] Dial Grease ?

[K4BEV at aol.com]

I'm quite sorry. I should have changed the Subject line before responding  to 
"Re: [Drake] hello?". It makes a thread much easier to find  later. So here 
it is again...
 
I'm using a T-4XC and R-4B combo. I've *modified* the R-4B so that the  dial  
lamp follows the TRANSCEIVE switch on the T-4XC just like the  R-4C's does. I 
had  an R-4C with no mods and so fell in love with the  R-4B once I heard one 
- 
Great  receiver, but I missed telling where the  TR switch was in the dark... 
Love that  blue glow!

My dilemma:  The main tuning dial on the T-4XC is as smooth as silk on silk,  
but  the R-4B develops what I will call "hard spots" after sitting for a   
while. Rocking the dial through the hard spots for a bit fixes  it,  till it 
sits in 
one place for a while with the radio off.
I believe that  the grease is hardening around the bearings and THAT is the   
problem.
It is more than likely the original lubrication.

Should I  just leave well enough alone or replace the grease? If replacement  
is  recommended; which grease should I use? Would leaving the receiver on 
STBY,  
instead of turning it off, keep the grease warm enough that the problem  
would  resolve itself? Is it advisable to just let it sit there in STBY  all 
of the 
time?
