Cast from iron for durability, this sheave features a 1.125 inch finished bore and a 3.75 inch outer diameter. The belt pitch diameter measures 3.4 inches, and the pitch diameter for 4L or A belt types is 3.0 inches. Licensed HVAC technicians, mechanical contractors, and equipment service professionals install this type of component when servicing or replacing belt-drive blower and fan assemblies.\u003c\/p\u003e\n\u003cp\u003eThis sheave is suited for residential and light commercial HVAC blower assemblies, exhaust fans, and other V-belt drive configurations requiring a two groove setup. It accepts standard 4L or A-section V-belts and is compatible with drive systems calling for a finished bore sheave in this diameter range. The finished bore eliminates the need for additional machining prior to installation, making it a direct-fit replacement option for worn or damaged sheaves in belt-drive systems.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eFinished bore at 1.125 inches — no machining required before installation\u003c\/li\u003e\n  \u003cli\u003eTwo groove design supports dual V-belt drive configurations\u003c\/li\u003e\n  \u003cli\u003eCast iron construction for strength and wear resistance\u003c\/li\u003e\n  \u003cli\u003eBelt pitch diameter of 3.4 inches for accurate speed ratio calculations\u003c\/li\u003e\n  \u003cli\u003eCompatible with 4L and A-section V-belts at a 3.0 inch pitch diameter\u003c\/li\u003e\n  \u003cli\u003eOverall length through bore of 1-31\/32 inches\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 systems requiring a two groove, finished bore sheave with a 3.75 inch outer diameter and 1.125 inch bore diameter accepting 4L or A-section V-belts.\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 all electrical power to the equipment before servicing any belt-drive assembly. Inspect belts, bearings, and the drive shaft for wear before mounting the new sheave, and verify shaft diameter matches the finished bore before pressing the component into place. Consult applicable OSHA guarding requirements for exposed belt and sheave assemblies upon completion.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSheave Type\u003c\/strong\u003e: Two Groove Sheave\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOuter Diameter\u003c\/strong\u003e: 3.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBore Diameter\u003c\/strong\u003e: 1.125 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBelt Pitch Diameter\u003c\/strong\u003e: 3.4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePitch Diameter (4L or A Belt)\u003c\/strong\u003e: 3.0 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length Through Bore\u003c\/strong\u003e: 1-31\/32 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Cast Iron\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 3.15 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31171804\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: BROWNING\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 1033364\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BROWNING","offers":[{"title":"Default Title","offer_id":51540047495474,"sku":"1033364","price":238.82,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/29caa5f6ddb744b346157b8b43fb2b80_9c45f532-adeb-4f82-8474-808524b01e6e.jpg?v=1785845991","url":"https:\/\/voomisupply.com\/products\/browning-1033364-two-groove-sheave-3-75in-od-cast-iron","provider":"Voomi Supply","version":"1.0","type":"link"}
