Understanding the Hub/Clutch Relationship
Kysor-style ON/OFF rear air fan clutch assemblies are two-piece systems. The first piece is the Fan Hub, which consists of an assembled pulley and mounting bracket. The second piece is the Fan Clutch, which turns on and off as needed to cool the engine.
Part number 1093-XXXXX-XX refers to an entire BorgWarner-Style fan clutch assembly. It is for reference purposes only and not available for ordering.
Most part numbers start with 1077, 1093 or 1090, but some newer hubs and assemblies start with 0100.
