[R-390] RF deck removal

[Alan Victor]

In the Y2K manual and the Army TM the instructions for
the removal of the RF sub chassis have you remove the
Oldham coupler backlash spring first. Then remove the
front panel following the procedure in a previous
paragraph. In that previous paragraph the KC knob is
to be rotated fully CCW to -963. QUESTION: Why not do
this first and then remove the backlash spring. Does it
matter? Not knowing any better,  it would seem I run some
risk turning the KC knob with the backlash spring removed.
Is the pressure present on the pressed couplings
sufficient that this is just not an issue? Or if I
rotate to -963, I cannot get to the backlash spring readily?

One last item. I notice in the TM a CAUTION that during the
removal of the RF sub chassis, the Oldham coupler on the
VFO shaft will come apart and the center disk will fall to the
bench. I can see my luck, it will fall on the floor never to be
found! This item is not in the Y2K manual, perhaps because
it can be handled in a better way? Or there is typically so much
grime and grease that it just does not fall off.

Comments?

Thanks again in advance!
