For the 6WD robot, you may have to shim the bearings so that all wheels touch the ground so after
mounting bearings and before installing the sprockets, slide the wheel axles into the bearings (with wheels
mounted) and turn the robot over on the wheels to check if the wheels are all touching the ground. Shim
the bearings as necessary. There are shims for 4 bearings provided, if necessary.
4. Couple the wheels with the provided #35 chain and connecting links. Make sure to cut the chain to a length
that will allow you to take all of the slack out by tensioning it. Tensioning the chain is done by sliding the
bearings that are mounted in the slotted holes. Next, mount the wheels to the axles using the five bolts that
come in the wheel. If you have a 4WD Robot, install the chain guards now, while you have the robot flipped
over (the 6WD robot does not need the chain guards). At this point you can also tighten all of the set
screws in the bearings to keep that shafts from sliding in the bearings.
