Fastener size recommendation may vary due to cover thickness, pulley diameters and system tension. *P/N=Polyester/Nylon ** Impact index provides a relative impact absorption value on any Goodyear construction assuming that the material size, material shape, drop height, impact idlers/bed, top cover and pulley cover are all the same. *** Average permanent elongation values at 100% of rated belt tension are based on ISO 9856 test procedure. Consult Goodyear field sales or GAD for elastic & total elongation calculations specific to each system based on Minuteman 2000 calculations. PLYLON LOAD SUPPORT (Maximum Belt Width) (mm.)

Consult Goodyear. Additional break in time is required when the belt has been stored prior to installation in ambient temperatures of less than 10 degrees Centigrade.
