Measuring 8 inches in diameter with a 1-inch bore, this zinc pulley transfers power from the motor to the blower shaft, directly driving airflow through the cooler. The keyway bore provides a positive mechanical lock on the shaft, preventing rotational slippage under load. It is installed by HVAC technicians and evaporative cooler service professionals during routine maintenance or component replacement when a worn or damaged pulley is causing belt slip, noise, or reduced airflow performance.\u003c\/p\u003e\u003cp\u003eThis pulley is used in residential evaporative cooler installations where a single-groove V-belt drive connects the motor pulley to the blower wheel assembly. It is a direct replacement part suited for window-mount, roof-mount, and side-draft evaporative coolers that use an 8-inch diameter, 1-inch bore single-groove pulley configuration. Technicians typically encounter this application during seasonal start-up service or mid-season repairs when belt drive components show wear.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e8-inch outer diameter with 1-inch keyway bore for secure shaft fitment\u003c\/li\u003e\n\u003cli\u003eSingle-groove design compatible with standard V-belt evaporative cooler drives\u003c\/li\u003e\n\u003cli\u003eZinc construction provides corrosion resistance in outdoor and rooftop environments\u003c\/li\u003e\n\u003cli\u003eKeyway slot prevents shaft slippage under continuous blower load\u003c\/li\u003e\n\u003cli\u003eRound profile ensures balanced rotation and reduced vibration during operation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement blower pulley for residential evaporative coolers requiring an 8-inch diameter, 1-inch bore, single-groove V-belt pulley.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eDisconnect power to the evaporative cooler at the disconnect switch or breaker before beginning any drive component service. A qualified HVAC technician or evaporative cooler service professional should verify belt tension and alignment after installing the pulley. Use the appropriate set screw or shaft key to secure the pulley to the blower shaft before applying power. Inspect the V-belt for wear and replace it if cracking or glazing is present.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eOuter Diameter\u003c\/strong\u003e: 8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBore Size\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGroove Configuration\u003c\/strong\u003e: Single groove\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Zinc\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: Silver\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShape\u003c\/strong\u003e: Round\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Type\u003c\/strong\u003e: Replacement Part\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: DIAL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 6314\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"DIAL","offers":[{"title":"Default Title","offer_id":51138765095218,"sku":"6314","price":20.72,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/179767-BQJokk.jpg?v=1778263183","url":"https:\/\/voomisupply.com\/products\/dial-6314-blower-pulley-8x1-inch-evaporative-cooler","provider":"Voomi Supply","version":"1.0","type":"link"}
