It regulates airflow and system pressure by transferring rotational force from the motor to the blower via a drive belt, allowing the driven component to operate at the correct speed. The pulley features a 3-3\/4 inch outside diameter and accepts a 5\/8 inch shaft. It is installed by HVAC technicians during routine maintenance or blower assembly service and serves as a direct OEM-style replacement to maintain original system performance and airflow balance.\u003c\/p\u003e\n\u003cp\u003eThis motor pulley is used in residential and light commercial HVAC air handler and packaged unit applications where belt-driven blower assemblies are employed. Confirmed compatible units include the 581CEV036060NA, 581CEV036072AA, and 581CEV036071AA, among others. It is suited for installations requiring a precise-fit motor pulley that matches original equipment dimensions and shaft tolerances to avoid belt misalignment or premature wear.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3-3\/4 inch outside diameter for correct belt engagement and speed ratio\u003c\/li\u003e\n  \u003cli\u003e5\/8 inch shaft bore for direct fit to standard motor shafts used in belt-drive blower assemblies\u003c\/li\u003e\n  \u003cli\u003eOEM-style replacement designed to match original equipment specifications\u003c\/li\u003e\n  \u003cli\u003eEliminates fitment risk associated with aftermarket or mismatched pulleys\u003c\/li\u003e\n  \u003cli\u003eCompact profile: 4.55 x 4.55 x 4.15 inches packaged dimensions\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eConfirmed compatible with units including 581CEV036060NA, 581CEV036072AA, and 581CEV036071AA.
