Belt Routing: Screw Takeup Drive

1. Remove the takeup guards on both sides of the drive. Remove the access panels on the drive
side opposite the gearmotor. See Figure 10: Screw Takeup Drive Overview.
2. Loosen the takeup jam nuts until the takeup screws turn freely. Turn the takeup screws
counterclockwise until the takeup carriage is as close to the drive pulley as it will go, without
unthreading the tensioner brackets from the takeup screws. Both screws must be turned by the
same amount to keep the takeup carriage square inside the drive. See Figure 29: General
Arrangement, Belt Under Roller AC, Screw Takeup Drive, Sheet 1 of 1 in Appendix 2: General
Arrangement Drawings for details and exploded views.
3. Check that both routing rollers and the drive snub roller are set square to the drive frame and
approximately centered within their slots. Adjust if necessary before the belt is installed. Using the
routing shown in Figure 11: Screw Takeup Drive Belt Routing, thread the belt through the drive.
The drive pulley will not turn easily with most gearmotor selections, so the belt will need to be
"pushed" rather than "pulled" past the pulley by providing slack just before the pulley.
4. Do not tension the belt at this stage. Refer to section 5.11.1 for belt tensioning and reassembly
instructions.
