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

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. .
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?
So I've heard people refer to a step reamer for the holes. Someone contacted me with one for sale. Is there a part number or tool number I should look for?

A reamer that is sized at 0.3261 will not fit a close tolerance bolt. That will fit an oversized bolt. The close tolerance bolt should be 0.312,
Oh good catch. I had it in my head that the holes were out of tolerance already (i.e. drilled with 5/16").
Marc, if you're still within the limits of the nominal size bolt, then I guess my 1/64" oversize reamer will be of no use to you.
