Subject: | Air box mod to fix filter deformation |
All,
This is a mod to the air box I did on the RV-10, and just now back fitted
onto the RV-8A.
Over the years with the RV-8A I've had to repair the air box and replace the
filter. As you can see from the first photo, the bottom of the filter
deforms (curves in). This tends to shorten the filter such that it drops
out of the top and impairs the seal with the top plate. I also had to add
fiberglass to the bottom of the air box as the relative motion between the
bottom of the air filter the air box eroded away the fiberglass bottom.
The fix was to add a .032" aluminum plate to the bottom of the air box. The
plate eliminates the bottom erosion and the added brackets hold the filter
shape. A side benefit is that alternate air door now sandwiches the bottom
fiberglass between two piece of metal making a sturdier install. I also
took the step to add proseal between the aluminum plate and the air box
bottom.
Carl
