If top cover and pulley cover are balanced (i.e., 3/16 in. x 3/16 in. or 4.7mm x 4.7mm) or less than 1/16 in. (1.5mm) differential (i.e., 3/16 in. x 5/32 in. or 4.7mm x 3.9mm), add 6 in. (152mm)
to the minimum belt width. 6 in. (152mm) narrower widths are possible if the belt is broken in for an extended period of time fully loaded. Consult your Sales Representative.
Additional break-in time is required when the belt has been stored prior to installation in ambient temperatures of less than 50°F (10°C).
