Before you unbolt a worn track roller or a weeping swing motor on a Kobelco SK480 or SK480LC hydraulic excavator, you want its correct part number, and this 724-page Kobelco SK480 parts catalog PDF (OEM ID S3LS00009ZE05) has it. Exploded views break the superstructure, undercarriage and attachments into numbered assemblies, from the slewing ring, idler adjuster and track rollers to the 7.0 m standard boom and 3.45 m arm with their hydraulic lines. Wiring diagrams trace the upper harness and controller group, and a parts index at the back cross-references each number to its figure. Order a holding valve only after confirming the listed set pressure of 39.7 MPa at 250 L/min, and match the 1.0 mm swing shim by its own part number. A wrong seal kit means a crew waiting on freight. Bookmarks and a searchable text layer take you from a part number to its exploded view in seconds.

Kobelco SK480, SK480LC Common Problems This Manual Covers
Kobelco SK480LC filter element part numbers for scheduled service hard to locate in the parts catalog
Check the filter list in the General Maintenance Items group starting on page 21, where the filters sit alongside the maintenance intervals. Copy the part number straight from that list, then confirm it against the Element Kit listing in Tools and Spare Parts on page 317 before ordering a full service set.
Manual Section: General Maintenance Items p. 21Can't identify the correct idler adjust assembly and roller assembly part numbers for the undercarriage
Check the Undercarriage group starting on page 261 and work through the chassis exploded views on pages 262 through 264. Locate the Idler Assy, Idler Adjust Assy and Roller Assy callouts, read each item number against the parts list, and confirm whether the machine is an SK480 or SK480LC before you place the order.
Manual Section: Undercarriage p. 261Arm hydraulic line parts don't match on a machine fitted with the optional short or semilong arm
Measure the arm and match it to the right listing before pulling a part number. The standard 7.0m boom and 3.45m arm with their hydraulic lines start on page 295, while the Short 3.0M and Semilong 4.04M arm assemblies sit in Optional Parts from page 325. Verify the hydraulic line callouts in the matching exploded view.
Manual Section: Attachments p. 295Can't confirm which relief valve assembly to order without the factory set pressure
Verify the set pressure listed in the catalog before ordering a replacement valve. The overload relief valve is listed at 400 kgf/cm² at 5L/min on page 415, and the relief valve assembly on page 502 shows F1 at 34.8 MPa at 30L/min. Cross-reference your old part number against whichever listing matches.
Manual Section: Hydraulic Components p. 415Alternator and regulator inner parts hard to identify when rebuilding instead of replacing the assembly
Check the Alternator & Regulator listing in the Mitsubishi 6D24-TL engine parts section, which breaks out the complete assembly and its inner parts. Decide whether you need the whole unit or individual components, then pull the part number from the matching list. Check the engine harness listing too if the connectors need replacing.
Manual Section: Alternator & RegulatorEngine overhaul gasket kit contents and part numbers unclear for a Mitsubishi 6D24-TL rebuild
Check the Engine Overhaul Gasket Kit listing in the Mitsubishi 6D24-TL engine parts section to see every gasket the kit covers. Compare it against the engine group index before ordering loose gaskets, so you don't double up. Verify the kit part number against the genuine parts information at the front of the engine catalog.
