It is an internal piston-side kit: published data lists a four-piece capped T-seal, with no rod seal or wiper. This matters when diagnosing leaks—external rod-end leakage needs a different kit. AH212091 is the substitute reference. Fitment is cylinder- and serial-specific: 310C loader boom applications change at serial 774762, while 450G, 550G, and 650G dozer cylinders have serial breaks. Send the cylinder number, bore size, cylinder function, and machine serial number for a compatibility check.\u003c\/span\u003e\u003c\/p\u003e\n\u003cbr\u003e\u003c!--TgQPHd||[]--\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"Fsg96\"\u003e\u003c!--TgQPHd||[]--\u003e\u003c\/div\u003e\n\u003ch2 id=\"s0-2-1-25-5-20-1-101[1]-2-3-7[0]-4[0]-3[0]-11[1]-1-5-title\" class=\"section-title__title\"\u003e\u003cspan class=\"ux-layout-section-module-evo__title\"\u003e\u003cspan class=\"ux-textspans\"\u003eItem specifics\u003c\/span\u003e\u003c\/span\u003e\u003c\/h2\u003e\n\u003ctable width=\"100%\" style=\"width: 100.088%; height: 345.571px;\"\u003e\n\u003ctbody\u003e\n\u003ctr style=\"height: 22.6641px;\"\u003e\n\u003ctd style=\"width: 33.6518%; height: 22.6641px;\"\u003e\u003cstrong\u003e\u003cmeta charset=\"utf-8\"\u003ePart Number:\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd class=\"et2\" height=\"17\" width=\"76\" style=\"height: 22.6641px; width: 65.9112%;\"\u003e\n\u003cmeta charset=\"utf-8\"\u003eAH149842\u003cbr\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 19.5938px;\"\u003e\n\u003ctd style=\"width: 33.6518%; height: 19.5938px;\"\u003e\u003cstrong\u003e\u003cmeta charset=\"utf-8\"\u003eFits Models:\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 65.9112%; height: 19.5938px;\"\u003e\n\u003cmeta charset=\"utf-8\"\u003e\n\u003cmeta charset=\"utf-8\"\u003e310C, 310D, 310E, 310G, 310SE, 310SG, 315SE, 315SG.\u003cbr\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 19.5938px;\"\u003e\n\u003ctd style=\"width: 33.6518%; height: 19.5938px;\"\u003e\u003cstrong\u003e\u003cmeta charset=\"utf-8\"\u003eBrand:\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 65.9112%; height: 19.5938px;\"\u003e\n\u003cmeta charset=\"utf-8\"\u003e \u003cspan\u003eJOHN DEERE replacement\u003c\/span\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 59.7812px;\"\u003e\n\u003ctd style=\"width: 33.6518%; height: 59.7812px;\"\u003e\u003cstrong\u003e\u003cmeta charset=\"utf-8\"\u003eType:\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 65.9112%; height: 59.7812px;\"\u003e\n\u003cmeta charset=\"utf-8\"\u003e\n\u003cp\u003eHydraulic Cylinder Bore Seal Kit\u003cbr\u003e80 mm Piston \/ Bore Seal Kit\u003cbr\u003eInternal Cylinder Piston Seal Kit\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 204.344px;\"\u003e\n\u003ctd style=\"width: 33.6518%; height: 204.344px;\"\u003e\u003cstrong\u003e\u003cmeta charset=\"utf-8\"\u003e \u003cspan\u003eApplication:\u003c\/span\u003e\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 65.9112%; height: 204.344px;\"\u003e\n\u003cul\u003e\n\u003cli\u003eFor resealing verified piston-side hydraulic cylinder assemblies on selected John Deere-compatible equipment.
