THE INSTALL MANUAL
Gregg C. ...
I finally got to the bottom of my MX-11 trouble. There was a shield wire
shorting out the conductor bringing com audio in .... so I was getting out
OK but hearing nothing from the radio receiver.
I'm sorry my first expanation was unreadable because of the broken
English/French gibberish ... that came from my spell checker somehow, so I
don't use that part of email until it's fixed.
Did you find the trouble with your MX-11?
Regards,
Jerry

A.J., did you send the pinouts under separate cover? I wasnt able to
find the file or a link in your response. I have a similar problem with the
MX11 and a PS Engineering 1000 intercom. The intercom is crystal clear. I
can hear everyone talking to me. My transmissions are unreadable. A
version of the pinout diagram found on the web has a hand written comment
about a resistor and capacitor mod required to the radios computer board.
Is this true? If so, does anyone have any more information on it? Jerry,
any luck with yours yet?

Dear Listers,
I'm just about to put the wheels on the axles. The manual indicates what kind
of grease to use, but doesn't really indicate whether you're suppose to use *more*
than is already gooped in the bearing when you open the Cleveland box. There
seems to be a fair amount of grease already there. What's the common notion
on this?
Thanks!

Subject: | Alternate RV-8 Gear Leg Alignment Proceedure |
Dear Listers,
I devised a different method for doing the initial gear leg alignment on the RV-8
this past weekend. When I flipped the fuselage back right side up and bolted
the axles on, I was very pleased to find that both the left and right gear
and axles are perfectly aligned without any shim. Best part was the procedure
is pretty easy and doesn't take much "tinkering" around to get right.
I bought two 8' long, 1.5" wide pieces of angle aluminium from the hardware store.
The kind *without* the radius at the center. I used the bolt pattern from
the wheel pant mount to drill two 1/4" holes in the center of each piece and
then bolted them to the gear legs. I then measured precisely between the gear
and came up with 65 11/16". I went back to Lowes and had them carefully cut
a piece of 3/8" particle board to the 65 11/16" measurement and left the 48"
side as is. Their gantry saw was off by about 1/16" in squareness but we flipped
the board over and sliced just enough off to make it exactly the desired width.
A measurement corner-to-corner showed that it was perfectly square.
I took this perfectly parallel piece of board and put into the channel formed by
the two pieces of aluminium angles between the gear legs. Its really easy at
that point to see if the gear legs are parallel or not and just as easy to adjust
them so they are. I added a couple of wood clamps and the whole thing was
very stable and rigid and allowed for accurate drilling of all the holes.
Once the fuselage was flipped back over, I used the same 8' long piece of angle
to check the toe-in/toe-out of both axles and found them to be perfectly aligned.
The angle really makes it easy to tell if they are in alignment.
Anyway, I thought I pass this process along for other builders. It seems a lot
easier and more accurate than using plumb bobs. I've attached a number of photos
of the setup.
Best regards,
Matt Dralle

I repacked in order to remove the red grease. I used one of the bearing packing
tools. I ended up with a little more than was originally there. I made sure
there was a bit on the felt where it contacts the spacer.
YMMV

There seems to be a fair amount of grease already there. What's the common notion

If they've sufficiently lubed between the rollers to pack it all in, and
there is enough grease next to the seal and around it, you should be
good to go. The thing you don't want to forget to do though is to
oil the felt seals if you have felt seals. Definitely do that.

Matt:
Having repacked, replaced bearings and races on my share of Cessnas, the
answer is "it depends". Were the bearings packed with a bearing packer, what
grease was used, and how long ago were they packed? If they came that way
from Van's or another supplier, and sat in storage, you have no way of
knowing, so I would wash it all out with solvent. Grease has a definite
shelf life, I replace in service AeroShell packings every year and chuck the
can after 24 months. Then repack them with a bearing packer ("Lisle" makes a
nice one) and apply a goodly swipe to the races as well. Don't go overboard,
this isn't one of those cases (like with duct tape) where a little is good,
a whole lot is better, it just runs out and all over everything, when put in
service. Keep the packer, you'll need it for your repacks at annual time.
