Matching the right seal kit or idler to your Kobelco SK220 hydraulic excavator is what 630 pages of factory exploded views buy in this Kobelco SK220 parts catalog PDF (OEM ID S3LQ1046), covering four variants of the series. Superstructure groups fill most of the book: engine, radiator, swing motor, control valve and the upper suction, delivery, main and return lines, with harness wiring diagrams and hydraulic line layouts tracing each route. Undercarriage pages break out the slewing ring, idlers, adjuster, rollers and shoes; attachments separate the 6.02 m boom and 2.98 m arm from 8.5 m and 10.1 m long-range options. Note the main relief valve set pressure of 380 kgf/cm² at 40 L/min (F1) before you price a replacement. A made-up relief setting is how hoses split under load. Bookmarks and a live text layer take a part number search straight to the right callout, so your first order is the right one.

Kobelco SK220, SK220LC, SK220v, SK220LCv Common Problems This Manual Covers
Kobelco SK220 filter element part numbers unclear when ordering for scheduled service intervals
Check the Filter List in General Maintenance Items on page 21 and copy each filter part number from the list before you call the parts counter. Then compare it with the Element Kit listing under Tools and Spare Parts on page 245 to make sure the kit matches the individual filters you pulled.
Manual Section: General Maintenance Items p. 21Port relief valve part number confusion because each port carries a different set pressure
Check the Hydraulic Components valve control listing on page 348 and match the replacement to its set pressure code before ordering. F1 is 385 kgf/cm² at 30 L/min, F2 is 400 kgf/cm² at 30 L/min, F3 is 230 kgf/cm² at 30 L/min, and F6 is 300 kgf/cm² at 190 L/min. Confirm the code on the parts list.
Manual Section: Hydraulic Components p. 348Main relief valve replacement hard to identify among similar relief valves in the hydraulic parts listing
Verify the main relief valve against the Hydraulic Components listing on page 346 before you order. Confirm the set pressure listed for the assembly: F1 is 380 kgf/cm² at 40 L/min and F2 is 370 kgf/cm² at 60 L/min. Don't substitute a port relief valve from the page 348 listing, because the settings are different.
Manual Section: Hydraulic Components p. 346Idler adjust assembly and roller assembly part numbers hard to pin down in undercarriage listings
Check the Undercarriage section starting on page 195 and go through the Idler Assy, Idler Adjust Assy and Roller Assy exploded views in order. The chassis parts diagram on page 196 shows where each assembly sits on the crawler. Match callout numbers against the parts list before ordering so you don't get the wrong idler or roller hardware.
Manual Section: Undercarriage p. 195Undercarriage O-ring size and part number unknown when ordering seals for reassembly
Check the undercarriage parts list on page 202. The O-ring is listed at callout 7 as size G75 1A, part number ZD11G07500, with a quantity of 2. Order the full quantity together, and match the callout to the exploded view on that page before you open the assembly.
Manual Section: Undercarriage p. 202Boom hydraulic line parts differ between standard 6.02m boom and optional 8.5m boom
Measure the boom on the machine before you pull any part numbers. The standard 6.02m boom, the 2.98m arm and their hydraulic lines are in Attachments starting on page 217, with the parts diagram on page 218. The 8.5m boom and its hydraulic lines are listed separately under Optional Parts starting on page 249.
