Note, the large wheels get a shim from the wheel bag between the bearings but not between the
eccentric spacer and bearing. The mini wheels get a shim from the wheel kit, between the bearings in
the wheel and between the bearing and eccentric spacer. All bolts are M5x25mm bolts. Note, you will
most likely need to remove the limit switch to install the one wheel bolt that resides behind it.
Begin by installing the standard spacers on the smaller holes (bottom row), these will be a reference for
the rest of the wheels. Tighten these with a small amount of torque, do not tighten so much that the
wheel drags or locks. Next, install the next row up eccentric spacers and mini-wheels. Before tightening,
turn the eccentrics until the wheel on this bolt is as close to the reference wheel below it. Install and
correctly tension the inner mini-wheels on the inside of the C-Beam (250 length), before installing the
outer larger wheels. Install the large wheels on the eccentrics and adjust to the beam in the same
fashion.
