Cast iron construction provides rigidity and dimensional stability under continuous load. The finished bore measures 1-1\/8 inches in diameter, and the outer diameter is 3.55 inches. The belt pitch diameter for B-section or A-section belts is 2.8 inches, with an overall through-bore length of 1-31\/32 inches. Licensed HVAC and mechanical technicians install this component when replacing or re-sheaving drive trains on air handlers, belt-drive fans, and similar rotating equipment.\u003c\/p\u003e\n\u003cp\u003eThis sheave is suited for residential and light commercial belt-drive applications where standard 4L or A-section V-belts are used. The two-groove configuration allows for dual-belt drive arrangements, which are common on heavier fan loads or where redundancy is required. The finished bore is ready to mount directly to a shaft of 1-1\/8 inches without additional machining.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eTwo-groove design accommodates dual 4L or A-section V-belts\u003c\/li\u003e\n  \u003cli\u003eFinished bore at 1-1\/8 inches — no machining required\u003c\/li\u003e\n  \u003cli\u003eCast iron construction for durability and dimensional stability\u003c\/li\u003e\n  \u003cli\u003eBelt pitch diameter of 2.8 inches for accurate drive ratio calculations\u003c\/li\u003e\n  \u003cli\u003eOuter diameter of 3.55 inches suitable for compact drive arrangements\u003c\/li\u003e\n  \u003cli\u003eThrough-bore length of 1-31\/32 inches for positive shaft engagement\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement sheave for belt-drive blower and fan assemblies using 4L or A-section V-belts with a 1-1\/8 inch shaft bore requirement.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eA licensed mechanical or HVAC technician should install this sheave. Disconnect and lock out all electrical power before accessing the drive assembly. Align the sheave parallel to mating drive components using a straightedge before tightening the shaft fasteners.
