Never force belts into a sheave with a tool such as a
screwdriver or a wedge. Doing so may rupture the envelope
fabric or break the cords.
Refer to Tables 3 and 4 (below and page 11) to determine if
enough clearance exists for belt installation and take-up.
For example, if you are installing a B75 HY-T® Plus belt, the
minimum allowable center distance for installation is 1.25
inches. For belt take-up, the minimum allowance above center
to maintain tension is 2 inches.
11. Matching belts
When using multiple grooved sheaves, be sure that all of the
belts are the same brand. Always replace complete sets of
V-belts even if only one is worn or damaged.
12. How to install belts
After you correctly install and align the sheaves, you can install
the belts.
Always move the drive unit so you can easily slip the belts into
the grooves without force.
