Caterpillar 350-8742 NSNBC01 V Belt

Caterpillar 350-8742 is a 1684 mm long ribbed belt, cataloged by Cat as the Long Ribbed Belt with part number 350-8742. The length converts to about 66.3 inches, and the ribbed profile is designed to engage pulleys in belt-drive assemblies used on Cat equipment. Some retailer catalogs also list this exact belt under the identifier NSNBC01 as “NSNBC01 - V Belt,” though Cat’s official listing identifies it by 350-8742 and describes it as a long ribbed belt. Dealer references associate 3508742 with Caterpillar machines such as the 930M, 323, and 938K, but fit is model- and routing-specific, so verify compatibility with your machine’s belt path and pulley configuration before purchase.
