I think the pictures and procedure that Scott's put together are marvelous.

Sometimes I'm not sure what to think:

1.  There is no such geartrain teardown/clean/rebuild procedure in the
    TM because they never thought that a tech would go to that level.

or

2.  The radio techs of the 50's and 60's had a lot more mechanical
    competence (and intuition for tearing down and rebuilding geartrains)
    than I do, and that one exploded diagram was more than enough for them.

I'm no slouch in terms of tearing apart and (usually!) putting back
together electromechanical gadgets, I THOUGHT.  Then I attempted
to rebuild my club's R-390A in the 80's, only with some phone help
did I get everything back together and then it was probably worse than
before!  Now here I am a quarter-century later and I can actually
do it, but only thanks Scott Seickel's resource (and some others too.)

Tim.
