Figure 13-26 shows how the belt will loop through the bearings and around the pulley. Take your
time; this can be a time-consuming activity (especially if you don't have an assistant). Once you have the
belt looped properly, you can either secure it to the tension rods with clips (see Figure 13-25) or have
your assistant hold the ends of the belt so that it doesn't slip.
Figure 13-26. Route the belt through the pulley and bearings.
Figure 13-27 shows a close-up view of the belt wrapped over the bearings and around the pulley.
Keeping tension on the ends of the belt will help prevent the belt from slipping off the pulley and
bearings.
