Subject: | Air Box Mod Due to Filter Deformation |
Can anyone explain why the filter would deform over time? Are you saying
that it also shrinks across its radius? Is it just this combination or is
this likely on my O320/RV-9A too? If it's caused by compressing the filter
to hold it tight, wouldn't it be better to use something like a foam gasket
to stop compressing it?

IMHO=2C the rubber shrinks and the rubber on the filter gets hard because i
t comes in contact with fuel and oil. The gas and oil makes the rubber shri
nk and get hard. Yes at one point the rubber will get soft from the fuel t
hen turn hard over time. I am on my 3rd filter in 15-years and have a spar
e one sitting on the shelf.
Yes the 320 has similar issues.
The placing of aluminum plate between the filter and fiberglass was done on
a friends IO-360 powered RV-4 over 10-years ago. I know of several RVs th
at have done that over the years. Actually=2C I cannot think of any flying
RVs with 360 up draft sump not using the aluminum. I though that was a st
andard mod that everyone was doing.

How often are you needing to replace the tires? What type/ manufacturer of tires
are you using now?
I had a similar, but not as severe shimmy in one main gear leg on my 6A. Replacing
the worn original kit tires with a set of Monster retreads from Desser Tires
solved the problem completely. I was amazed at the difference.

Subject: | Landing Gear Shimmy on RV8a |
Ok, I hate to take you way off the reservation here but Vans miss-shipped some
RV-8A kits with RV-9A gear legs. Ask me how I know? I purchased a partially built
kit from about your era (Builder # 80721) and it shipped with the 9A legs.
We knew something was not right when we tried to align the wheels. This was most
obvious when pushing backwards. The only reason I of know this is the same
thing happened to at least 2 other 8A builders that contacted me through the
list. We cleaned up the legs and returned them to Vans for a free replacement
~8+ years later. (Thank you Vans!). At least one flew several hours before discovering
the issue. Mine would not push backwards more than a few feet w/o skipping
so I have no idea one can push in/out the plane in this configuration. Now
this is pretty unlikely to be your issue and I am sure that others will chime
in on the shimmy problem. Just wanted to let you know of the gear leg issue
just in case.
Robin
