This is a fairly easy process the way BJ builds these and as long as you get it tight, it will be hassle free. Well, it is for me.
You will start with the following pieces.


Take the bolt, pass it barely through the wheel pant. Place two of the small plywood donuts on the bolt from the inside. Then place the tire on the bolt.


BJ intends for you to the place the wheel collar that comes in the wheel mounting bolt kit. I opted to use the 3rd and 4th lock nut that he also provides. So anyway, place whichever you prefer next. Then place the washer next. You will have to bend the wheel pant out to do this.


Make sure you push the bolt all the way through now while screwing it into that first nut. Get it where you want it with no binding. Then you want to push it through the landing gear hole and install another washer, then the locknut. Tighten it down. I only had to install my allen wrench in the bolt, and a socket on the outside nut and tighten it down to get it really tight. Make sure there is no binding of the wheel while doing this. You may have to adjust the inner nut if you used the nut. Maybe the wheel collar is better for it than the inside nut ; )


Now do the other side. Line them up with the fuse to get them where you want them. Or place the plane on the ground and line them up with the ground.
