Back Wheels


Figure 1
1. Slide an axle into a set screw axle hub until it is flush with the flat side of the hub. Tighten the set screw using the 3/32" hex key (Figure 1). Place the set screw axle hub on the wheel and align the holes so the set screw faces the flat side of the axle. Use 1/2" SHCSs to fasten the wheel to the set screw axle hub.


Figure 2
2. Insert two bronze bushings in the hole where you want to place the axle – there will be one on each side. Push the end of the axle into the axle hole. Lock the axle in place by placing an axle set collar over the end and pushing it against the bushing (Figure 2). Turn the collar until the screw is facing the flat side of the axle. Use the 1/16" hex wrench to secure it to the axle.

3. Repeat Steps 1-2 for the other side.
