[R-390] Question about the Y2K manual... (or how Randy can bedumb as a rock)...

[ka9egw at britewerkz.com]

+1 on Scott Seickel's tutorial.  Good stuff!  I think the entire
disassembly, cleaning and reassembly took me less than a day start to
finish, plus a bunch of time figuring out the much-less-than-1/3-tooth
incremental error in the y2k manual's description of the 7+000 position of
the Geneva machanism...which I've already written up at the request of
"Perrier".

Also there are several manuals, including TM-11-5820-358-35 [field and depot
maintenance], available as .pdf's also from r-390a.net.

Randy,

Once again; check out Scott Seickel's excellent " R-390A Gear Train
Rebuild". http://www.r-390a.net/faq-refs.htm  Scroll down the page, gud
references! The hard part for most is organization. When taking this beast
apart, lay the parts out in some type of order. Fasteners for each part
should remain with that part, etc. Could put screws back into the hole from
which they came until time to put it all back together.

If you are cleaning the gears, clean one at a time, then place it back in
the correct location per Scott's instructions. Worked for me.

  I'm confused (nothing new)...  so please someone set me in
the right direction and give me a swift kick.  I'm putting
my gear train back together (I'll post about some VERY big
"surprises there another time"...   and using the Y2K
manual.  On pages 191 - 195 is the zoning chart for the
exploded gear train shown in 6-36.  Great. should make
getting the shims, spacer bushings, etc. in the right
place(s) much easier. Uh-huh.  I start trying to use the
chart  - and find that what seemed obvious a short time ago
- now has me totally confused.  I look at the diagram -
there is a gear set with "call out" (index?) 41.  I look at
the chart - Index 41 = 1/4 inch retaining ring.  Two shims
and bushing on the shaft of 41 marked 42 & 43 - but the
chart lists them as No. 8 riveted gear and 4-40 square nut.

What am I obviously overlooking????

rg - making dumb and dumber looking smart and smarter by the
day...
