Guide
Installation	Shown above, eXPANDHUB® adapter modules, center marker, and assembled. eXPNADHUB® system and treaded track installation and removal. Before installation carefully inspect and make sure motor mounts, motors, bearing blocks, and set screws are installed and tightly fitted. Next pre-install three long wheel bolts (9 per side) onto each adapter. Place eXPANDHUB® adapter module (with bolts positioned as shown) onto shaft. Use a 1" plastic PVC/ABS pipe to gently tap hub/bolt assembly into place flush with bearing collar. Install lock collar in place and tighten set screws. Set screws help keep the collar in place, collars help keep hub assemblies aligned and true to chassis and drive system as intended. Install half wheels onto each shaft installed hub/bolt assembly. Install preassembled treaded tracks onto each half wheel one side at a time from back wheel to front. Front and rear wheels (motors) maybe manually rotated to help simplify installation. With tracks assembled on to wheel halves, proceed by installing the remaining/external half wheels. Secure each assembled wheel using nuts as shown. To remove, follow the steps above in reverse order.
