It is used for the arm\/dipper cylinder and carries a 40 mm rod × 70 mm bore reference. This size is also associated with the U27-4 boom cylinder kit RH418-71390, but the two kits serve different cylinder positions and must not be treated as interchangeable. For buyers ordering multiple U27-4 repair kits, the original part number is the most reliable way to separate boom, arm, bucket, swing, and blade applications. Ruijueparts supports direct part-number matching, multi-SKU RFQs, and neutral or customer-specified packaging.\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\"\u003eRH418-71490\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\"\u003eU27-4, U27-4CA \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 to reseal the designated dipper or arm cylinder on Kubota U27-4 compact excavators.
