Machined from cast iron, it features a 0.875 inch bore diameter and a 4.75 inch outer diameter. The pitch diameter measures 4.5 inches for 4L or A-series belts and 4.16 inches for 3L-series belts. The through-bore length is approximately 1-5\/32 inches. At 1.75 pounds, this sheave suits both new installations and direct replacement work on HVAC air handlers, rooftop units, and belt-driven ventilation equipment. Installation is typically performed by licensed HVAC technicians or millwrights.\u003c\/p\u003e\n\u003cp\u003eThis sheave is suited for residential and light commercial belt-drive systems where a single groove, A-series or 4L-series V-belt is used. Common applications include furnace blower assemblies, air handler fan drives, exhaust fan drives, and general-purpose motor-to-shaft power transmission. The finished bore accepts a 0.875 inch shaft directly without additional machining, making it a straightforward drop-in replacement or new-build component for standard belt-drive configurations.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eFinished 0.875 inch bore — no additional machining required for standard 0.875 inch motor or blower shafts\u003c\/li\u003e\n  \u003cli\u003eSingle groove design accepts 3L, 4L, or A-series V-belts\u003c\/li\u003e\n  \u003cli\u003e4.75 inch outer diameter with 4.5 inch pitch diameter for 4L or A-series belts\u003c\/li\u003e\n  \u003cli\u003e4.16 inch pitch diameter for 3L-series belts\u003c\/li\u003e\n  \u003cli\u003eCast iron construction for durability and dimensional stability under load\u003c\/li\u003e\n  \u003cli\u003eCompact 1.75 pound weight suitable for residential and light commercial drives\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation sheave for belt-driven blower and fan assemblies using 3L, 4L, or A-series V-belts with a 0.875 inch shaft bore.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by a licensed HVAC technician or qualified mechanic.
