Yes, I put a borescope up the nose leg and verified there are no threads there. The pin used only holds the bolt from falling out the bottom. The nose gear does not have a "radius stop" pin in the front. It doesn't even have the bolt pin sticking out the front. As soon as I sheared the pin, the bolt fell right out.

Galin,

This is a photo of my nose gear.  The pin you see inserted in the front of the leg is a "radius stop"
which hit the aluminum stop blocks and prevents the wheel from turning too much to either side.
The pin is solid ss and threaded into the leg.  I remember the original instructions in the manual recommended
using a roll pin but many people had problems with it shearing off which is why I beefed up mine.
Are you sure the roll pin in your leg is for holding the bolt?  It might be the pin originally meant for a radius stop.
Have you removed the bolt from the leg and saw it wasn't threaded?

I like the idea of having a fitting on the nose fork so you can grease it without taking the fork completely off. I will be doing this mod to my fork.

The nose gear origionally had a "radius stop" which, as I recall (not a very reliable source) was simply a roll pin in the nose rod and one on each side of the fork. The roll pins sheared off with some regularity and I never was able to make a good fix. Just made it a practice to avoid sharp turns. Your solution with blocks fixed on each side of the fork is neat (as long as you use something tougher than a roll pin in the nose rod). Wish I had thought of that.

Well Dave I would still rely on your recollection for things like this. This isn't my solution but I am going to "borrow" it for the airplane.
