Built around the Series 696 platform, the kit measures up to 18 inches and delivers readings in 0.001-inch dial graduations on a 0-20-0 bi-directional dial face. The kit includes a balancing attachment that extends coverage from 2-3\/8 inches to 18 inches, giving technicians a wide measurement range in a single organized package. Machinists, engine builders, and precision measurement professionals install and use this kit for accurate crankshaft bore inspection.\u003c\/p\u003e\n\u003cp\u003eThe 52901 kit is suited for automotive and industrial engine rebuilding shops where crankshaft bore distortion measurement is part of the machining and quality-verification workflow. The 18-inch maximum range and included extension attachment allow measurement across a broad range of engine block bore sizes. The kit is organized as a complete unit, reducing the need to source individual components separately. It is appropriate for use in professional machine shop environments where tight tolerances and repeatable measurements are required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.001-inch dial graduation for high-resolution distortion readings\u003c\/li\u003e\n  \u003cli\u003e0-20-0 bi-directional dial face for direct plus-or-minus deflection reading\u003c\/li\u003e\n  \u003cli\u003eBalancing attachment covers 2-3\/8 inches to 18 inches measuring range\u003c\/li\u003e\n  \u003cli\u003eMovable bezel allows zero-setting at any position on the dial\u003c\/li\u003e\n  \u003cli\u003eNon-breakable crystal protects the dial face during shop use\u003c\/li\u003e\n  \u003cli\u003e12-piece kit includes one extension for flexible setup configurations\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style crankshaft distortion measurement solution compatible with STARRETT Series 696 dial gage components and accessories.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis kit is installed and operated by machinists and precision measurement technicians in engine rebuilding and machine shop environments. Before use, ensure the engine block is secured and all rotating assemblies are stationary. Follow the setup sequence provided in the STARRETT Series 696 documentation to mount the balancing attachment and zero the dial before taking measurements. Do not exceed the rated 18-inch measuring range, as overextension may affect calibration and dial accuracy.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 696\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eKit Type\u003c\/strong\u003e: Crankshaft Distortion Dial Gage\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Pieces\u003c\/strong\u003e: 12\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMeasuring Range\u003c\/strong\u003e: 18 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDial Graduation\u003c\/strong\u003e: 0.001 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDial Reading\u003c\/strong\u003e: 0-20-0\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGage Depth\u003c\/strong\u003e: 2-3\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncludes\u003c\/strong\u003e: 2-3\/8 to 18 inch balancing attachment, one extension\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDial Face Features\u003c\/strong\u003e: Movable bezel, non-breakable crystal\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 2.75 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: California Proposition 65\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 41111600\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: STARRETT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 52901\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STARRETT","offers":[{"title":"Default Title","offer_id":51540149535026,"sku":"52901","price":973.61,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/02d81f93b5abb22ce967144c75cc8e7f.jpg?v=1785847162","url":"https:\/\/voomisupply.com\/products\/starrett-52901-crankshaft-distortion-dial-gage-kit-12-pc","provider":"Voomi Supply","version":"1.0","type":"link"}
