It is intended to renew applicable rod-end and piston-end sealing positions when the slew ram shows hydraulic leakage, reduced holding performance, or requires planned overhaul. Fitment depends on the cylinder arrangement and machine serial range—not the model name alone. Confirm the equipment serial number, side-shift or center-mount configuration, cylinder reference, and old seal details before ordering. Ruijueparts supports B2B part-number lookup, multi-SKU sourcing, and neutral or customer-specified packaging.\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\u003cdiv role=\"heading\" class=\"otQkpb\"\u003e\u003cbr\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\"\u003e991\/00018, 99100018\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\"\u003e3CX, 3C, 3D, 4CX\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\u003eJCB 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\"\u003eHydraulic Cylinder Seal Kit \/ Slew Ram Seal Kit\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\"\u003eApplication: Hydraulic slew\/swing ram seal service for a verified 110 mm JCB backhoe loader cylinder.\u003cbr\u003eService purpose: Technicians remove and dismantle the slew ram, inspect the rod, bore, piston, and gland condition, install the verified seal set, reassemble the cylinder, and test side-shift or slew movement.\u003cbr\u003eFitment control: Match the machine serial number and cylinder configuration before quotation.\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eBackhoe Loader: \u003cmeta charset=\"utf-8\"\u003e3CX, 3C, 3D, 4CX\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.
