4. To mount the wheel shafts, place the bearing in the outer hole in the tube and slide the shaft through it
with shaft collars on either side of the bearing. The shaft collar inside the tube is used to mount the shaft
to the motor. Make sure to use the longer set screw provided (1/4-20 x .375”) here and tighten it down
through the hole in the side of the shaft and onto the flat part of the motor shaft. Make sure the set
screw tightens down onto the center of the flat spot so there is minimal backlash in the wheel. Some
backlash in the motor gearbox is normal but if you are able to turn the wheel ¼ turn or so, check that the
set screw is in the right place. If it is not, the motor shaft can get damaged. Again, make sure to use
Loctite on the set screws.
