Notes: ■ The belt sizes shown in this chart are based upon initial drive set-up with the adjustable pulley at minimum pitch diameter (open) and the

spring-loaded pulley at maximum pitch diameter (closed). The driven speed range and the resulting ratios shown in this chart are derived from mathematical calculations based upon exact center distances, constant motor speeds and manufacturers' belt specifications. Actual results will differ due to variations in any of these factors. ■ When referencing the Lovejoy UPC number in this table, include 685144 as a prefix to the number shown in the tables above.
