Built from cast iron with a B-style bushing mount, this sheave accepts 5V, A, and B cross-section belts and accommodates bore diameters from 5\/8 inch up to 2-1\/4 inches. The outside diameter measures 9.28 inches, with a 5V belt pitch diameter of 9.1 inches and a B-belt pitch diameter of 9.0 inches. The QD bushing design allows for quick installation and removal without specialized pullers, making field service efficient on belt-driven fan and blower assemblies. At 18.05 pounds, this is a substantial cast-iron component suited for medium to large drive systems.\u003c\/p\u003e\n\u003cp\u003eThis sheave is commonly used in belt-driven blower and fan assemblies found in commercial HVAC air handlers, rooftop units, and industrial ventilation systems. The four-groove configuration supports multi-belt drive setups that require higher torque transmission or added redundancy. It is sized for systems using 5V, A, or B series V-belts, making it a versatile option across a range of drive configurations. HVAC mechanics and millwrights typically install this sheave during motor or blower drive replacements, sheave upgrades, or speed adjustments accomplished by changing sheave diameter ratios.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eFour grooves accommodate 5V, A, and B cross-section V-belts\u003c\/li\u003e\n  \u003cli\u003eQD (Quick Detachable) B-style bushing mount for fast installation and removal\u003c\/li\u003e\n  \u003cli\u003eOutside diameter of 9.28 inches with 5V pitch diameter of 9.1 inches\u003c\/li\u003e\n  \u003cli\u003eBore range from 5\/8 inch to 2-1\/4 inches covers a wide range of shaft sizes\u003c\/li\u003e\n  \u003cli\u003eCast iron construction for durability in continuous-duty belt drive service\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eCompatible with 5V, A, and B cross-section V-belts.

Disconnect and lock out all electrical power to the motor before servicing the drive assembly. Match the bushing bore to the shaft diameter and verify belt tension and sheave alignment with a straightedge or laser alignment tool after installation. Do not overtighten bushing cap screws beyond the fastener manufacturer specifications stamped or listed on the bushing.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Grooves\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCompatible Belt Sections\u003c\/strong\u003e: 5V, A, B\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 9.28 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBelt Pitch Diameter (5V)\u003c\/strong\u003e: 9.1 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBelt Pitch Diameter (B)\u003c\/strong\u003e: 9.0 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Bore Diameter\u003c\/strong\u003e: 5\/8 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Bore Diameter\u003c\/strong\u003e: 2-1\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBushing Style\u003c\/strong\u003e: B (QD Quick Detachable)\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: 18.05 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: 3694601\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BROWNING","offers":[{"title":"Default Title","offer_id":51538342773042,"sku":"3694601","price":366.56,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/fa6fd761d924dfac2a665d782a602bad.jpg?v=1785823380","url":"https:\/\/voomisupply.com\/products\/browning-3694601-qd-bushed-v-belt-sheave-4-groove","provider":"Voomi Supply","version":"1.0","type":"link"}
