Axle mount holes

[Ron B.]

Anyone have trouble installing the four NAS 1304 (I think) 29 close tolerance bolts in the main gear legs that fasten the axles. Holes in my right gear leg are a little undersize (left leg fit tight as needed). I tried an AN-4 bolt and it will not go either. Did send an e-mail to Van's but that will take til middle of next week for an answer.
Anyone know the tolerance for these bolts? I'm doubtful a 1/4" reamer will be called for here, probably something under sized.

I had the same problem, but only on the right gear leg. I ran a under sized drill bit through the tight holes. This was just enough to get the bolts through with slight encouragement from a small hammer.

The closes undersized I have is a "D" drill bit but the hole still appears to be too tight. I suspected others would have the same problem.

Just received a reply from Sterling @ Van's and he said a 1/4" reamer is just what the callout requires for these holes. I have that reamer.
