Mechanical Assembly
1. Start by mounting the motors as shown in the figure below, with the motor spacer plate between the
motor and the chassis. Make sure to use Loctite on the screws. Once the motor is mounted, the small D-
shaft sprockets can be mounted on the motor shaft. The hub should face the motor and they should be
pushed all the way against the inside plate with just a small clearance for rotation.
2. Slide all 8 bearings into place through the bearing holes in the chassis. Slide a lock collar onto the axle,
then slide the axle through the first bearing. Then slide the sprocket onto the shaft and push the shaft
through the second bearing. Slide another lock collar on to secure the inside bearing and slide the outside
lock collar over to secure the outside bearing. Use Loctite on all set screws. Wait to mount the wheels
until chains are attached and tensioned. For now, tighten the set screws to keep the sprockets in place.
They will need to be roll pinned to the shaft in a later step.
