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? Ian Brown ________________________________ Message 2 _____________________________________ Time: 07:08:24 AM PST US From: RV6 Flyer Subject: RE: RV-List: Air Box Mod Due to Filter Deformation 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. Gary A.

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. Jeff Orear RV6A.

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.
