Default Just me

Mine came out exactly like Bruceís . This thing gets sealed with tank sealent anyway and I figure that will cover the hole. I dont see a need to maintain this rivet.

Dont forget the washer between the main gear and spar. It is best to fit it now while the botom skin is off. Some washers may need trimming.

No. I didn't touch the weldment. Just kept working the skin and flange. I used a dremel with a grinding bit. Lots of putting it on and taking it off till it fit perfect. I'm sure they are all a little different. Maybe I got lucky. Worth a call to Van's but I think that hole can for removed if necessary.
I assume you figured out the two or three nutplates have to be removed to get the gear in place. Also, remember the washer.
The other item to check is interference with the wing bolts. Mine were an issue. The drift pins would hit the gear weldment hole. I had to file the holes a little (Vans Advise). Last thing you want when it's time to mount wings is bolt interference.

Consider that the skins in this area are likely the same for tail or nose dragger. Losing a couple sheet metal holes around the weldment, which vastly strengthens the area, won't matter.

Thanks, Larry. Yes, Van's confirmed too: Make the gear fit and forget about the hole.

Sorry, What washer? Studying the drawings I donít see any oddly placed washers.

Look at spot A4-5 on the drawing and read that big block of text pointing to the one bolt. One washer goes between center section and gear mount.

Yup, one washer had to have the edge filed to fit right, the other side was ok as is. I taped these to the spar so i wouldnt lose them when it comes time to final install.

Also, when trimming for the gear and “loosing the hole” i forgot to include the space need to tighten the gear. Mine just fits, but i think i will need to grind more for “sinch up” room. Thanks for the warning, mr “wire jock” larry. Just in time too, I am about to flip the canoe.
