I always had difficulty in removing the lower cowl because of the lower cowl inlet baffles which were rivet on at the inlets. The dimensions caused the lower cowl to hit the back of the spinner plate before it would drop down. I removed the riveted on seals and replaced with a removable plate and seal for each side. Each attaches with three screws after the lower cowl is installed. This eliminate the clearance problem and works well. I believe the removable seals allow for more overlap and better seal to the upper than before. Ignore the 1/8 rivet holes where the old baffle was attached at least for now. I like it. Will work on the link later today, thanks

Try this one !! If you notice right pic you can see where the spinner has scratched all the paint off the lower cowl

Note the nice, even wear marks on Walt's seals. There are a few leaky spots, but not many.

This seems like a good idea - do you have any photos of the inside?

No, but I might be able to get you a pic of the baffle as removed. Comes out with 3 screws. The baffle mtl is riveted to an alumin plate and has three random located nut plates attached . So the baffle mtl is sandwiched between the alumn and the cowl when attached. Bottom side would show only alumn and nutplates.

Thanks for adding the pic, I 've never been able to do that!! Didnt know that was the RV 10 method but it also works well on my 9 and yes aside from nutplates vs a AN nut, thats exactly same. Having the nutplates allow me to remove the seal before the cowl comes off.

That big 'ol hole behind #3 can't be helping!
