It is a single sealing-support component within the brake system, not a hydraulic cylinder seal kit or a complete brake overhaul kit. A backup ring must be installed in its designated brake-piston sealing position with the correct associated seal components. Similar-looking rings in the HD785-7 front brake assembly have different references and must not be substituted without checking the parts diagram. Confirm the machine serial number, brake assembly reference, and the complete list of parts being replaced before ordering.\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%;\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 33.7188%;\"\u003e\u003cstrong\u003e\u003cmeta charset=\"utf-8\"\u003ePart Number:\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 65.8534%;\"\u003e\n\u003cmeta charset=\"utf-8\"\u003e561-34-71590, 5613471590\u003cbr\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 33.7188%;\"\u003e\u003cstrong\u003e\u003cmeta charset=\"utf-8\"\u003eFits Models:\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 65.8534%;\"\u003e\n\u003cmeta charset=\"utf-8\"\u003eHD785-7\u003cbr\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 33.7188%;\"\u003e\u003cstrong\u003e\u003cmeta charset=\"utf-8\"\u003eBrand:\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 65.8534%;\"\u003e\n\u003cmeta charset=\"utf-8\"\u003e \u003cspan\u003eKomatsu replacement\u003c\/span\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 33.7188%;\"\u003e\u003cstrong\u003e\u003cmeta charset=\"utf-8\"\u003eType:\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 65.8534%;\"\u003e\n\u003cmeta charset=\"utf-8\"\u003eBrake Backup Ring\u003cbr\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 33.7188%;\"\u003e\u003cstrong\u003e\u003cmeta charset=\"utf-8\"\u003e \u003cspan\u003eApplication:\u003c\/span\u003e\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 65.8534%;\"\u003e\n\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cmeta charset=\"utf-8\"\u003eSystem: Front wheel brake sealing assembly.\u003cbr\u003eFunction: Supports the specified sealing element within the brake-piston arrangement.\u003cbr\u003eEquipment: Selected Komatsu HD785-7 rigid mining dump trucks.\u003cbr\u003eVerification required: Confirm the truck serial number, front brake parts diagram, and exact part reference before ordering.\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eRigid Mining Dump Truck: HD785-7\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 33.7188%;\"\u003e\u003cstrong\u003e\u003cmeta charset=\"utf-8\"\u003eSize:\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 65.8534%;\"\u003e\n\u003cmeta charset=\"utf-8\"\u003e \u003cspan\u003eStandard Size\u003c\/span\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003cp\u003e\u003cspan\u003e\u003cbr\u003e\u003cmeta charset=\"utf-8\"\u003e\u003c\/span\u003e\u003cspan\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003ch2\u003e\u003cspan\u003eFAQ\u003c\/span\u003e\u003c\/h2\u003e\n\u003cp\u003e1.
