Measuring 7 inches in diameter with a 1-inch bore, it features a keyway slot that locks the pulley to the blower shaft, preventing slippage under load. Cast from zinc, it delivers a balance of corrosion resistance and dimensional consistency. HVAC technicians and evaporative cooler service professionals install this part during routine maintenance or when replacing a worn or cracked pulley that causes belt slippage, noise, or reduced airflow output.\u003c\/p\u003e\n\u003cp\u003eThis pulley is suited for residential evaporative cooler blower assemblies where a 7-inch diameter, single-groove pulley with a keyway is required. It is a direct-replacement component used in ducted and side-draft evaporative cooler configurations common in dry-climate residential installations. The keyway design ensures positive shaft engagement and consistent belt alignment during operation.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e7-inch diameter single-groove design for standard evaporative cooler blower shafts\u003c\/li\u003e\n  \u003cli\u003eKeyway bore ensures secure shaft fit and eliminates rotational slippage\u003c\/li\u003e\n  \u003cli\u003eZinc construction provides corrosion resistance suitable for wet-environment cooler service\u003c\/li\u003e\n  \u003cli\u003eRound profile supports accurate belt tracking and smooth power transfer\u003c\/li\u003e\n  \u003cli\u003eDirect OEM-style replacement format minimizes fitment adjustments during swap-out\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement blower pulley for residential evaporative coolers requiring a 7-inch diameter single-groove pulley with a keyway bore.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by an HVAC technician or evaporative cooler service professional. Disconnect power to the cooler at the disconnect switch or breaker before beginning any pulley or belt service. Verify bore diameter and keyway dimensions match the blower shaft before pressing or seating the pulley. Inspect the drive belt for wear and replace it if cracking or glazing is present before returning the unit to service.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 7 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBore\u003c\/strong\u003e: 1 inch\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\u003eGroove Style\u003c\/strong\u003e: Single-groove\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eKeyway\u003c\/strong\u003e: Yes\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: DIAL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 6310\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"DIAL","offers":[{"title":"Default Title","offer_id":51138453930290,"sku":"6310","price":20.32,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/179765-Hd1Bmm.jpg?v=1778256871","url":"https:\/\/voomisupply.com\/products\/dial-6310-blower-pulley-7-inches-evaporative-cooler","provider":"Voomi Supply","version":"1.0","type":"link"}
