The swing cylinder moves the rear excavator assembly from side to side, so it must be distinguished from the boom, dipper, bucket, stabilizer, and steering cylinders when ordering. This kit is commonly associated with JCB 214 and 3CX machines using listed swing cylinder references. Confirm the cylinder number, machine serial number, and rod\/bore dimensions before purchase. Ruijueparts supports reference lookup and multi-SKU sourcing for B2B repair orders.\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\"\u003e991\/00163, 99100163 \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, 214\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\"\u003eSwing Cylinder Seal Kit \/ Hydraulic Cylinder Seal Kits \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\"\u003eHydraulic system: Repairs selected swing\/slew cylinders that shift the rear digging assembly laterally during backhoe operation.\u003cbr\u003eEquipment use: JCB backhoe loader swing ram applications.\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eBackhoe Loaders: 3CX, 214 \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.
