[R-390] Sticking R-390A clutch plate.

[Philip B Atchley]

Hello all.
Perhaps a month ago I had the RF deck out of this '67 EAC and very
thoroughly cleaned the gear train and cam assembly. I didn't tear the
gear train down as I didn't feel I wanted to go that far.  The entire
mechanism is very 'free' and easy tuning.

In use though, I have noticed a problem with the Zero Adj clutch.  If I
haven't adjusted the Zero adjust for a couple days, when I crank down the
knob (to release the clutch) and then tune the KC knob the clutch sticks
or drags the Veeder Root counter off Zero until it "breaks free" and then
it's ok and good to go for future adjustments.       

I 'suspect' that old grease and grime may still be lurking on the clutch
plate and that's causing the problem.  Is there a way to clean this
critter WITHOUT having to remove the RF deck again and disassembling the
gear train?   If I have to go through that I'll probably just live with
it until the next time I have cause to do a teardown (the receiver is in
daily use).
