OM, I'm holding one of those in my hand, even as we speak. It feels
bumby, so to speak, and is dry as a bone. What I've done is work in
some WD so as to clean some of the old grease out and then work some new
lubricant in. I'm told the unit uses a pressed in bearing and can't be
taken apart, short of ruining it. That's the word I have.... It worked
on two Valiants I've re-done and the drive is the same as on your Ranger.

I am starting the reassembly of my Ranger. The large brass VFO dial
drive mechanism (Jackson Drive?), is a bit tight and bumpy when
turned. I tried getting a little light oil down inside where the thing
rotates but this didnt seem to help much. Can this thing be taken
apart and lubricated somehow? After turning it a bunch it seems to
have loosened a slight amount but still can barely turn it by hand and
feels like the bearings are dry. Any suggestions?? Thanks de Randy,
