Cast from iron, this sheave features a 0.75 inch finished bore and a 6.25 inch outer diameter, making it a direct-mount, ready-to-use component without secondary machining. The groove is sized to accept standard B-section and A-section V-belts, with a belt pitch diameter of 6.0 inches for 4L or A belt types and 5.66 inches for 3L belt types. Licensed HVAC technicians and mechanical contractors install these sheaves on blower assemblies, fan drives, and pump drives. Overall bore length is 1-5\/32 inches.\u003c\/p\u003e\n\u003cp\u003eThis sheave is suited for single-belt drive applications in residential and light commercial HVAC systems, particularly on air handler blower shafts, condenser fan assemblies, and belt-driven pump systems. It accommodates 4L, A, and 3L profile V-belts and fits standard 0.75 inch motor or blower shafts. The finished bore is ready for setscrew or key retention as required by the application. Mechanical contractors and HVAC technicians select this part as a replacement or new-install sheave where a single groove, moderate-diameter drive is specified.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eFinished 0.75 inch bore — no additional machining required\u003c\/li\u003e\n  \u003cli\u003e6.25 inch outer diameter with 6.0 inch pitch diameter for 4L or A belt types\u003c\/li\u003e\n  \u003cli\u003e5.66 inch pitch diameter for 3L belt types\u003c\/li\u003e\n  \u003cli\u003eCast iron construction for durability in continuous-duty drive applications\u003c\/li\u003e\n  \u003cli\u003eSingle groove design for straightforward single-belt drive configurations\u003c\/li\u003e\n  \u003cli\u003eOverall bore length of 1-5\/32 inches for adequate shaft engagement\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-install single groove sheave for belt-driven HVAC blower, fan, and pump assemblies using 4L, A, or 3L profile V-belts on 0.75 inch shafts.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by a licensed HVAC technician or mechanical contractor. Disconnect and lock out all power to the drive system before removing or installing any sheave.
