Another Hammond Run Problem

[PAULMACVEY@delphi.com]

Just another Hammond owner of a long-stored model M (cir.
1949, I
think) which has some problems getting started.  I've been
watching the postings involving such problems, and I've
not been
able to get hammond oil, so I resorted to 3-in-1, which I
know
isn't supposed to be used, but since it has done wonders
on an
old '20's fan, I used it in desperation, as there aren't
any
organ repairmen for miles around.  Well, still won't run -
the
start motor won't even turn it over unless I spray it's
gears
with WD-40.  Then it grunts, but if I spin the disks
connected
with the two springs, it finally gets the generator up to
speed -
sometimes!

Tonight, I disconnected the two springs, and, wow!  The
start
motor whipped the generator alone up to speed in nothing
flat!
After filling the little square cup closest to the motor
with the felt glob in it, and letting a little oil run
down the three little threads, and
reattaching the two drive springs, it finally got the
whole works
up to speed.  After a couple of trys with the run switch,
it
finally kept humming for maybe five minutes or so, then
abruptly
ground to a halt.  It was playing good, and sounding not
too bad
either except for a terrible growling sound from each
pedal note.
Even the volume picked up as I played it.  Not much
vibrato, but
you could tell some difference when it is switched on and
off.

My question - what are the mechanics of the rectangular
box with
the oil reservoir sitting on top of it, and what's inside?
 A
bunch of bearings, perhaps?  Is it possible to dismantle
and look
inside without cutting/unhooking wires to the motor?  I
think the
gears and/or bearings inside or perhaps motor armature
bushings
are dragging, as when I turn on the run switch
momentarily, it
seems to have regular, evenly spaced magnetic "drag
points."

If this machine can start running reliably, I'd like to
think
about either feeding the speaker output to perhaps one
that
rotates, like the Allen Rondo of the '60's used, or
something to
create a cheap tremelo effect.  Anyone know what the
impedance of
the 12" cabinet speaker is?  I've noted discussion about
tapping
into these instruments for output, but I'm no radio
technician,
so I don't want to start roaming around the capacitor
field with
a loose soldering gun and X out the whole amplifier!

Any suggestions would be appreciated.  When I left it
tonight, I
put a little more oil in the felt-filled box on the
rectangular
box between the round case (motor?) and the
spring-connected
disks.  (Anybody got a schematic and/or a parts list so I
know
what to call these strange-looking parts?)

Mucho Gracias,
