It is an individual backup ring within the brake sealing arrangement, not a complete seal kit or a general-purpose O-ring. During brake service, the ring must be matched to its designated position and mating sealing component to support the intended brake-piston sealing arrangement. Although several similar ring references are used in the same front wheel brake group, they are separate parts. Verify the truck serial number, brake assembly drawing, and full parts list 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\"\u003e561-34-71680, 5613471680\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 brake sealing element within the brake-piston assembly.\u003cbr\u003eEquipment: Selected Komatsu HD785-7 rigid mining dump trucks.\u003cbr\u003eVerification required: Confirm the machine serial number, front brake assembly 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.
