Landing gear bolts
I want to replace the top bolts that secure the main landing gear to the mounts under the seats with close-tolerance oversize bolts. I know I will have to ream the holes. Has anyone done this and if so, what bolts and reamer did you use?
thanks
-Marc

yip, I just fixed mine, I went and reamed the holes with a 5/16 reamer for the an 5 bolt, big mistake! I barrowed a piloted reamer, I forget the size, and got a set of oversized bolts, NAS 6605-29X ( this is for my 7A ) and it worked out great! Genuine Aircraft Hardwar has all the parts you will need.

Why are you going to close tolerance bolts? Just curious is all.

The RV-10 needs NAS6605-33X bolts.
Note that the dash number for the NAS bolts differ from AN bolts.
As Bret mentioned, Genuine Aircraft Hardware has all this, including the corresponding piloted reamer.
I had to do this about a month ago.

Thanks Bret, I was hoping to find someone who had done this on a -10 and could just tell me the bolt and reamer to use, being lazy and all... ;-)

I found that the existing bolts allowed the MG wheels to move back and forth a fair amount. This was happening inside the top mount where the holes are too large for the bolts. Just a little play translates to a lot of movement out at the wheel.

I just installed the main gear a few months ago. My plans (page 46-4) say to drill with a 7.9 mm drill bit and use AN5-24A bolts. Where are you seeing NAS6605-33X?

Correct, I guess what I meant to say was, if you want to go with close tolerance bolts, then use NAS6605-33X.
The reason I went with them, is because I inadvertently used 5/16" bit.
