| Subject: | Air Filter - Air Box Installation |
--> RV9-List message posted by: RICK LUCK <rluck@prodigy.net>
In doing the annual on my RV, our A&P has found kind of an unusual air fitler installation.
As you guys probably know, the bottom of the accelerator pump extends
about 1/2" below the surface of the carburator, where the top of the air
box is attached. The accerator pump bottom then extends about 1/2" into the
air box. Unfortunately, where it protrudes into the air box just happens to line
up exactly with where the edge of the air filter mates up to the top of the
air box. The solution that the builder of my plane used was to simply cut out
a knotch in the air filter gasket edge about 1/2" and then re-form a new seal
around the accelerator pump w/ RTV silicone. We're looking for an improvement,
to eliminate the possibility of some RTV material becoming dislodged from
the makeshift gasket and being ingested into the carb. We've looked at offsetting
the air box so it's not centered on the carb inlet but then we're worried
about missalignment with the air inlet in the cowling.
We've also discussed using an automotive air filter that consists of a wire basket
and foam filter, thinking we could deform the wire basket to mis the accerator
pump hump and the foam would still conform to the basket, essentially creating
a filter that wasn't perfectly round. Have any of you run into this problem
and if so, what was your solution? Thanks for the help. Rick Luck

I built a spacer out of alum (I was thinking it was 5/8" but maybe only
1/2") so that I didn't have to modify the filter. As I recall, Van's
solution was as described below and apparently works OK. With the spacer you
have to tilt the air box up slightly also.

It sounds like the builder followed Van's instructions on installing
the air filter. The instructions do state to take care that there are
no loose pieces of sealant that could be sucked into the intake.
There may be a better solution, but this is the way mine is, and I
would expect just about every other RV has theirs done the same way.

I got mine through Falcon. (referred by EAA) 1% of the covered value seems to
be standard. I now have my regular insurance with Falcon. They beat Avemco by
a mile!
