Manufactured from cast iron, this sheave features a 3.35-inch outer diameter and a 7\/8-inch finished bore, ready for direct shaft installation without additional machining. The belt pitch diameter is 2.6 inches for Type 4L or A belts, and the groove width measures 13\/16 inches. Weighing 0.9 pounds, this compact sheave suits light-duty to medium-duty belt drive configurations. HVAC technicians and mechanical contractors commonly specify this component for blower and fan drive assemblies.\u003c\/p\u003e\n\u003cp\u003eThis sheave is suited for residential and light commercial HVAC systems, as well as general industrial belt drive applications where a Type 4L or A V-belt is used. It is typically installed on motor or driven-shaft assemblies operating blower wheels, fans, or other rotating equipment. The 7\/8-inch finished bore accepts standard shaft diameters directly, making it a straightforward drop-in for common motor shaft sizes found in air handling and ventilation equipment.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSingle groove design accepts Type 4L or A V-belts\u003c\/li\u003e\n  \u003cli\u003e3.35-inch outer diameter with 2.6-inch pitch diameter\u003c\/li\u003e\n  \u003cli\u003e7\/8-inch finished bore — no additional machining required\u003c\/li\u003e\n  \u003cli\u003e13\/16-inch groove width for proper belt seating\u003c\/li\u003e\n  \u003cli\u003eCast iron construction for durability in belt drive service\u003c\/li\u003e\n  \u003cli\u003eLightweight at 0.9 pounds for easy handling and installation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-fit sheave for single-groove V-belt drive assemblies using Type 4L or A belts with a 7\/8-inch shaft bore requirement.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified HVAC technician or mechanical contractor. Disconnect and lock out power to the drive system before removing or installing any sheave.
