The kit supplies a matched cylinder bore and piston assembly sized specifically for two-stroke power cutter applications where consistent ring seal is critical for reliable starting and full cutting RPM. Mechanics and equipment technicians use this cylinder piston ring kit to rebuild top ends on high-hour saws that have lost compression from normal ring and bore wear.\u003c\/p\u003e\u003ch4\u003eBuilt For Performance\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eOversize-matched 51mm bore and piston set restores factory compression and peak power output\u003c\/li\u003e\n\u003cli\u003eHard-chrome plated cylinder wall resists scuffing and extends ring life under sustained high-RPM operation\u003c\/li\u003e\n\u003cli\u003ePre-gapped piston rings reduce end-gap setup time and promote immediate ring seal during break-in\u003c\/li\u003e\n\u003cli\u003eLightweight cast piston with drilled oil return holes prevents ring sticking at elevated cutting temperatures\u003c\/li\u003e\n\u003cli\u003eCirclip grooves machined with tight tolerances keep wrist pin retention secure through continuous vibration\u003c\/li\u003e\n\u003cli\u003eKit includes cylinder, piston, ring set, wrist pin, and circlips as a complete top-end rebuild package\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eFits These Machines\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003efor Husqvarna K770\u003c\/li\u003e\n\u003cli\u003efor Husqvarna K760\u003c\/li\u003e\n\u003cli\u003efor Husqvarna K760 Active II\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eOn-The-Job Use\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eTop-end engine rebuild on power cutters used in concrete cutting and road work\u003c\/li\u003e\n\u003cli\u003eRestoring compression on rescue and fire department saws that must start reliably under load\u003c\/li\u003e\n\u003cli\u003eOverhauling high-hour masonry and demolition saws that have lost power and become hard to start\u003c\/li\u003e\n\u003cli\u003eField rebuilds where replacing the complete cylinder assembly is faster than honing and re-ringing alone\u003c\/li\u003e\n\u003cli\u003ePipe and utility cutting applications that run saws at wide-open throttle for extended periods\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eSpecs At A Glance\u003c\/h4\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eBore Diameter\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e51mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eKit Contents\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eCylinder, piston, ring set, wrist pin, circlips\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eCompatible Brands\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eHusqvarna\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eCompatible Models\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eK770, K760, K760 Active II\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003ch4\u003eGood To Know\u003c\/h4\u003e\u003cp\u003e\u003cstrong\u003eQ:\u003c\/strong\u003e What break-in procedure is recommended after installing this cylinder piston ring kit? \u003cstrong\u003eA:\u003c\/strong\u003e Run the saw with a rich fuel mixture for the first two to three tanks, avoiding prolonged wide-open throttle to allow the rings to seat evenly against the cylinder wall.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eQ:\u003c\/strong\u003e Can this 51mm kit be used if the original bore is worn beyond the standard size? \u003cstrong\u003eA:\u003c\/strong\u003e The kit provides a standard 51mm bore and piston assembly intended to replace a cylinder that is still within specification for this diameter, so measure the existing bore before ordering.\u003c\/p\u003e\u003cp\u003e\u003cem\u003eSlight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.\u003c\/em\u003e\u003c\/p\u003e","brand":"Solid Spare","offers":[{"title":"Default Title","offer_id":44965032984662,"sku":"ZZ3A00699","price":89.09,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0697\/8460\/0662\/files\/57_689d4dab-31d4-45ec-bdb7-bdaac57b6d06.jpg?v=1781652526","url":"https:\/\/www.solidspare.com\/products\/51mm-cylinder-piston-ring-kit-for-husqvarna-power-cutter-saw-k770-k760-active-ii","provider":"Solid Spare","version":"1.0","type":"link"}
