[R-390] R390 Clutch/Differential Gear Assembly Details

[Leigh Sedgwick]

Hi All,

I am working through a rebuild of my R390A RF deck including
a complete teardown and cleaning of the gear train. 
Everything was going fine until I decided to clean the split
gears on the clutch/differential gear assembly.  The 2 split
gears were froze together.

I should know by now when disassembling something to leave
it in one orientation.  Well, I didn't and turned it and all
of a sudden I have a handful of spring shims without a clue
on how to reorient them upon assembly.  Here is a picture of
the sping shims - notice the names of the JPG picture files
:-)

I pulled apart the rest of the clutch assembly and did my
best to keep everything in its original orientation as shown
in the next 2 pictures.

My best guess for spring shim orientation is shown in the
next 3 pictures.  But they could easily be oriented the
opposite way (hell, maybe it doesn't matter).

Anyone on the relector here have some first hand knowledge
of their proper orientation?

I have reassembled the unit and it appears to function as
before (best I can tell without having it in the receiver)
but I don't trust a guess and would sure like to get this
confirmed before I completely reassembly the RF deck.  Here
are pictures of it reassembled.

While I'm at it, if anyone knows the order orientation of
the brass spacers shown previously in pictures 2 and 3 so I
can confirm their positions that would be great too.

Anyone have a current e-mail address for Scott Seickel?  The
one listed in his gear train pictures no longer works.

Thanks in advance for the help.
