The sheave features a 6.95-inch outside diameter and accepts Q1-style quick-detach bushings, allowing straightforward bore sizing across a range of shaft sizes from 0.75 inches to 2.6875 inches. With a belt pitch A diameter of 6.2 inches and a belt pitch B diameter of 6.6 inches, this sheave is suited for both A-section and B-section V-belt configurations. At 13.5 pounds, it is a solid, production-grade component installed by HVAC technicians and mechanical contractors in fan, blower, and pump drive assemblies.\u003c\/p\u003e\n\u003cp\u003eThis sheave is commonly used in belt-driven blower and fan systems found in commercial and residential HVAC equipment, as well as general-purpose industrial drive applications. The three-groove design allows it to carry multiple V-belts simultaneously, distributing load across the drive assembly. It is appropriate for new installations and direct replacement of worn or undersized sheaves where a Q1-style bushing is already in service or available. HVAC and mechanical technicians regularly use this part when resizing drives for motor replacements or system reconfigurations.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eThree-groove configuration supports multi-belt A-section and B-section V-belt drive systems\u003c\/li\u003e\n  \u003cli\u003eQ1-style QD bushing mount enables tool-accessible bore sizing and quick removal\u003c\/li\u003e\n  \u003cli\u003eBore range of 0.75 inches to 2.6875 inches accommodates a wide variety of shaft sizes\u003c\/li\u003e\n  \u003cli\u003e6.95-inch outside diameter with 6.2-inch A belt pitch diameter and 6.6-inch B belt pitch diameter\u003c\/li\u003e\n  \u003cli\u003eSolid construction at 13.5 pounds provides stability in continuous-duty drive applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a QD-bushed replacement sheave for three-groove V-belt drive assemblies using Q1-style bushings and A-section or B-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. De-energize and lock out the motor and drive system completely before removing or installing the sheave. The Q1-style bushing must be properly seated and fastened to the correct torque specification per the bushing manufacturer before returning the drive to service. Inspect V-belts for wear and verify belt tension and alignment after installation to prevent premature sheave or belt wear.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eModel\u003c\/strong\u003e: 3B66Q\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Grooves\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 6.95 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBelt Pitch A Diameter\u003c\/strong\u003e: 6.2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBelt Pitch B Diameter\u003c\/strong\u003e: 6.6 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Bore Diameter\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Bore Diameter\u003c\/strong\u003e: 2.6875 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBushing Style\u003c\/strong\u003e: Q1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 13.5 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: 1010735\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BROWNING","offers":[{"title":"Default Title","offer_id":51544164106546,"sku":"1010735","price":272.21,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/11f0f7a8bbbd49bcf5648f469f1f307d_7e4a9028-351e-4a9a-9130-1df6c76d1f80.jpg?v=1785925031","url":"https:\/\/voomisupply.com\/products\/browning-1010735-3b66q-qd-bushed-v-belt-sheave-3-groove","provider":"Voomi Supply","version":"1.0","type":"link"}
