York S1-028-12361-700 Pulley Variable 320788-702 For shallow wells where airThe York S1 028 12361 700 Pulley Variable is an essential OEM component designed for precise HVAC blower speed adjustment and airflow balancing. As a variable pitch sheave, this part allows technicians to fine tune the drive ratio by adjusting the distance between the threaded angular discs. When the flanges are moved closer, the belt pitch diameter increases, raising the driven speed; conversely, widening the gap lowers the diameter to reduce fan
