It features a 1.375-inch inside bore diameter and a 6.5-inch outside diameter, with two grooves machined to accept 4L, 5L, A, and B cross-section belts. The sheave is cast from iron for durability and dimensional stability under continuous cyclic load. Face width ranges from 1.625 to 2.375 inches depending on pitch adjustment, and sheave thickness is 3.25 inches. Licensed HVAC technicians and mechanical drive specialists install this component when field-adjustable motor-to-blower speed ratios are required.\u003c\/p\u003e\n\u003cp\u003eThis sheave fits residential and light commercial air handling units, rooftop units, and belt-driven blower assemblies where variable airflow tuning is needed without replacing the drive assembly. It is suited for installations where the system speed must be set or fine-tuned during commissioning or after blower motor replacement. The 2VP65138 accommodates multiple belt trade sizes, making it a practical stock item for service techs handling a range of equipment.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eVariable pitch design allows field adjustment of drive ratio without changing sheaves or belts\u003c\/li\u003e\n  \u003cli\u003eTwo-groove configuration accepts 4L, 5L, A, and B cross-section V-belts\u003c\/li\u003e\n  \u003cli\u003e1.375-inch bore diameter with 6.5-inch outside diameter for mid-range blower drive sizing\u003c\/li\u003e\n  \u003cli\u003eCast iron construction provides rigidity and resistance to belt-induced radial loads\u003c\/li\u003e\n  \u003cli\u003ePitch diameter range of 4.75 to 5.98 inches for 4L or A belts; 5.24 to 6.45 inches for 5L or B belts\u003c\/li\u003e\n  \u003cli\u003eMinimum open turns of 6 for both 4L or A and 5L or B belt types\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eCompatible with 4L, 5L, A, and B cross-section V-belts.

Disconnect and lock out all power to the unit before removing or installing any drive components. Ensure the sheave is properly aligned with the mating sheave using a straightedge or laser alignment tool before tensioning the belt. Adjust pitch setting to the required position before final tightening, and verify belt tension and tracking after startup.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Bore Diameter\u003c\/strong\u003e: 1.375 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 6.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Grooves\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSheave Thickness\u003c\/strong\u003e: 3.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFace Width Range\u003c\/strong\u003e: 1.625 to 2.375 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCompatible Belt Sections\u003c\/strong\u003e: 4L, 5L, A, B\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePitch Diameter Range (4L or A)\u003c\/strong\u003e: 4.75 to 5.98 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePitch Diameter Range (5L or B)\u003c\/strong\u003e: 5.24 to 6.45 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Open Turns (4L or A)\u003c\/strong\u003e: 6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Open Turns (5L or B)\u003c\/strong\u003e: 6\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: 12.3 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 8 inches x 8 inches x 3.38 inches\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: TB WOOD'S\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 2VP65138\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TB WOOD'S","offers":[{"title":"Default Title","offer_id":67907704062258,"sku":"2VP65138","price":308.67,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7d57e8151454fe9b35c375c1828d49f1_6180ca7c-d7b3-465a-826d-618e01c81671.jpg?v=1791181100","url":"https:\/\/voomisupply.com\/products\/tb-woods-2vp65138-variable-pitch-sheave-2-groove","provider":"Voomi Supply","version":"1.0","type":"link"}
