It is referenced for the arm\/dipper cylinder, commonly associated with a 45 mm rod and 75 mm bore. This position controls the extension and retraction of the excavator arm, while the boom, bucket, swing, and blade cylinders on the same machine use separate repair-kit references. For buyers managing repeat service parts, ordering by the original RG518-67630 reference helps keep cylinder applications distinct across a mixed fleet. Ruijueparts supports direct part-number matching, multi-SKU RFQs, selected legacy-equipment sourcing, and neutral or customer-specified packaging for distribution programs.\u003c\/span\u003e\u003c\/p\u003e\n\u003ch2 class=\"section-title__title\" id=\"s0-2-1-25-5-20-1-101[1]-2-3-7[0]-4[0]-3[0]-11[1]-1-5-title\"\u003e\u003cspan class=\"ux-layout-section-module-evo__title\" data-testid=\"ux-textual-display\"\u003e\u003cspan class=\"ux-textspans\"\u003eItem specifics\u003c\/span\u003e\u003c\/span\u003e\u003c\/h2\u003e\n\u003ctable style=\"width: 100.088%; height: 293.907px;\" width=\"100%\"\u003e\n\u003ctbody\u003e\n\u003ctr style=\"height: 19.5938px;\"\u003e\n\u003ctd style=\"width: 33.8353%; height: 19.5938px;\"\u003e\u003cstrong\u003e\u003cmeta charset=\"utf-8\"\u003ePart Number:\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 65.899%; height: 19.5938px;\"\u003e\n\u003cmeta charset=\"utf-8\"\u003eRG518-67630\u003cbr\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 39.1875px;\"\u003e\n\u003ctd style=\"width: 33.8353%; height: 39.1875px;\"\u003e\u003cstrong\u003e\u003cmeta charset=\"utf-8\"\u003eFits Models:\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 65.899%; height: 39.1875px;\"\u003e\n\u003cmeta charset=\"utf-8\"\u003eKX91-3 \/ KX91-3 Alpha variants, KX101-3 Alpha variants, U30-3 \/ U30-3 Alpha variants, U35-3 \/ U35-3 Alpha variants, U35 Alpha 2, U25-3 Alpha\u003cbr\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 19.5938px;\"\u003e\n\u003ctd style=\"width: 33.8353%; height: 19.5938px;\"\u003e\u003cstrong\u003e\u003cmeta charset=\"utf-8\"\u003eBrand:\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 65.899%; height: 19.5938px;\"\u003e\n\u003cmeta charset=\"utf-8\"\u003e \u003cmeta charset=\"utf-8\"\u003e \u003cspan\u003eKubota \u003cmeta charset=\"utf-8\"\u003ereplacement\u003c\/span\u003e\u003cbr\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 19.5938px;\"\u003e\n\u003ctd style=\"width: 33.8353%; height: 19.5938px;\"\u003e\u003cstrong\u003e\u003cmeta charset=\"utf-8\"\u003eType:\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 65.899%; height: 19.5938px;\"\u003e\n\u003cmeta charset=\"utf-8\"\u003e \u003cmeta charset=\"utf-8\"\u003e \u003cspan\u003eHydraulic Cylinder Seal Kit \/ Dipper Cylinder Seal Kit \/ Arm Cylinder Seal Kit\u003c\/span\u003e\u003cbr\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 176.344px;\"\u003e\n\u003ctd style=\"width: 33.8353%; height: 176.344px;\"\u003e\u003cstrong\u003e\u003cmeta charset=\"utf-8\"\u003e \u003cspan data-path-to-node=\"3,9,1,0\"\u003eApplication:\u003c\/span\u003e\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 65.899%; height: 176.344px;\"\u003e\n\u003cmeta charset=\"utf-8\"\u003e\n\u003cul\u003e\n\u003cli\u003eUsed for the designated dipper or arm cylinder on selected Kubota compact excavators.
