Undercarriage parts fill roughly a third of this 748-page Kobelco SK80CS, SK80MSR parts catalog PDF (OEM ID S3LF00001ZE02), breaking the crawler excavator's idler, idler adjuster, rollers, ring assemblies and track shoes down to individual part numbers before the book widens to the superstructure, swing bracket, boom, arm, cab and engine. Exploded views carry the load here: every callout ties a component on the drawing to its part number, so the pin, bushing or seal you order matches what came off your machine. Wiring diagrams trace the upper harness and controller group, and hydraulic schematics lay out line routing for the upper structure and attachments. Where a valve's set pressure is printed, you read it directly: 29.4 MPa at 28 L/min on one, 20.6 MPa at 30 L/min for F1 on another. A made-up pressure figure can cost you a pump. Bookmarks by figure group and a searchable text layer take you to the assembly you need in seconds.

Kobelco SK80CS, SK80MSR Common Problems This Manual Covers
Kobelco SK80CS/SK80MSR engine water separator part number does not match the old unit removed
Check your machine serial number before ordering, then go to the filter list on page 24. Serials LF01-00501 through 00518 take water separator 113200-8410; LF01-00519 and later take 897218-6470. Order the fuel filter element 894414-7963 and engine oil element kit 897049-7081 on the same order so the service gets done in one stop.
Manual Section: General Maintenance Items p. 24Hydraulic filter element and tank breather element part numbers hard to find in the parts book
Check the filter list on page 24 under General Maintenance Items. The hydraulic filter element is YR50V00004P1, supplied in element kit YR50V00006F2, and the hydraulic tank breather element is YN57V000028002. Pull the air cleaner element LE11P000028002 from the same table so every filter for the service goes on one order.
Manual Section: General Maintenance Items p. 24Replacement swing cylinder part number varies by serial range and the wrong cylinder gets quoted
Verify your serial number against the swing bracket assembly list on page 39 before ordering. LF01-00501 to 00502 uses LF01V00002F1, LF01-00503 to 00542 uses LF01V00002F2, and LF01-00543 onward uses LF01V00002F3. Order the cylinder installation shims from the same list: sizes 0.5, 0.9 and 1.2 (LF02B01029D1, D2, D3).
Manual Section: Superstructure p. 39Can't match tube nut and sleeve part numbers to the tube size on the machine
Measure the tube size in millimeters, then find it in the nut and sleeve tables on page 25. The tables list two series: ZA93S sleeves with ZA93N nuts for 10 to 35 mm tube, and ZF93S sleeves with ZF93N nuts for 6 to 38 mm tube. For a 15 mm tube in the ZA series, order ZA93S15000 with ZA93N15000.
Manual Section: General Maintenance Items p. 25Radiator hose, thermostat and thermo sensor part numbers needed for a cooling system repair
Check the engine assembly list on page 47 first. The radiator hoses are YT05P01004P1 and YT05P01020P1, the thermostat is 894214-9620, the thermo sensor is YT52S00001P1 and the thermo switch is 897125-6000. For internal Isuzu engine parts, go to the Engine Components section starting on page 691, and confirm your engine assembly suffix against your serial range.
Manual Section: Superstructure p. 47Counterweight shim and rubber part numbers needed when reinstalling the counterweight after removal
Check the counterweight assembly list on page 43 before you reinstall. The shims come in three thicknesses, three of each: YT60C01006D1 (3.2), YT60C01006D2 (2.0) and YT60C01006D3 (1.0). The counterweight rubber is YT60C01004D1 and the plug is YT60C01007P1. Order washers PH60C01011P1 on the same order so the counterweight goes back on with the right hardware.
