[R-390] Cleaning R-390 gears in place before lube

[Roger Ruszkowski]

Charles,
 
You are absolutely right.
 
Taking a gear train all the way down and getting it clean
is the way to go.
 
Any one can learn to do it and get it right on the first pass.
 
But does the receiver need that level of effort?
But does the owner have the time, place and tools?
 
Every situation is different and having dry bathed more than one gear train.
I still agree there is nothing that will match a good full disassembly and cleaning.
 
You point that you flush more grit into the bearing before you start getting the thing clean is a 
good point.

Once you start a dry bath, you have to continue until you have every thing flushed out.
Any thing less than a full gallon of solvents brushed in blown around and blown out is not
enough to do the process.

There was a time when these receivers received four hours of love twice a year.
The idea was to get ahead of the curve and keep the receiver clean.

One pass way not be enough.

But do it once this summer.
And then do it again next summer.
And in a few years you have a clean machine.
