This Fenner 8.4 design pulley is built to match original equipment specifications for old style 36" belt drive coolers. It's a composite-construction replacement part, meant to restore smooth belt tracking and motor-to-fan power transfer on aging 120V units. Matching the original pulley design matters here — mismatched pulley diameters or profiles change belt tension and fan speed, which can shorten belt and motor life.
