[R-390] RF Gear Question

[Barry]

Jon,

Sounds like your clutch is slipping when it should not be.  Perhaps the
internal springs are missing/broken?  Maybe some of the clutch disks are
missing?  At any rate, it should not do that.

I've worked on a couple of these things and they are pretty
straight-forward.  Properly cleaned and assembled, they don't slip and do
indeed require significant pressure on the "nipples" to disengage the clutch
disks.

Good luck,

Barry - N4BUQ
