Materials and Tools

Note

• Prior to assembling the axles, ensure that the 10mm axle is cut to proper size and edges are deburred.
• The bearings will require significant force to insert them into the carriers, be cautious during this process.
• Prior to full assembly, ensure all pieces that slide onto the 10 mm shaft go on smoothly. This will help when it comes time to place the entire assembly together.

Procedure

1. . Take the bearings and press-fit them to either side of the bearing carrier.
2. . After both bearings have been fitted, slide the axle shaft into the assembly. Allow about 5-6 mm to protrude out the back of the housing
3. . Once the axle is inserted, place a 10mm collar on the shorter end to hold the axle from slipping out of the carrier.
4. . Take the 72-tooth gear and insert the 5 listed bolts in each slot. Ensure that the hex heads are sitting flush within the gear itself.
5. . Once the bolts are fitted, slide the gear onto the axle-carrier assembly. Ensure that the gear is sitting as far as it can go in on the shaft, as it has a built in spacer to prevent contact between the gear and the carrier.
6. . Lay the listed wheel flat on a sturdy surface to prepare for the tire install.
7. . Take the tire and begin to press it over the ridges on the wheel. If too much resistance is present, apply a light layer of lubricant around the wheel ridges to help the tire slide on.
8. . Once the tire is mounted to the wheel, slide the wheel onto the axle while lining it up with the bolts coming from the 72-tooth gear.
9. . After the parts are lined up, take the 3mm nuts and tighten them down to unite the 72-tooth gear with the wheel.
10. . Tie together the assembly by placing a 10mm collar at the face of the wheel, preventing the parts from sliding off the front of the shaft.
