Which part actually fits a given hydraulic excavator is settled by one source: the 864-page Kobelco SK115SR-1E, SK115SRL-1E parts catalog PDF, factory OEM ID S3YV00005ZE07, which lists both machines exactly as they left the line. Exploded views fill most of the book, with the superstructure taking the largest share and the undercarriage idlers, rollers, slewing ring, boom, arm, pumps, valves and regulators each broken down to numbered callouts. Wiring diagrams and hydraulic schematics let you trace a harness or a remote control line before ordering, and the filter list gathers every element your service kit calls for. Read the relief valve setting as 37.8 MPa at 30 L/min, and order sleeve ZA93S15000 for a 15 mm tube. A swing motor can sit stripped for days over one seal number. The bookmarked, text-searchable file prints cleanly, so the pages you need can go to the bench and soak up hydraulic oil.

Kobelco SK115SR-1E, SK115SRL-1E Common Problems This Manual Covers
Kobelco SK115SR-1E hydraulic tube sleeve part number unclear when matching a replacement sleeve to tube size
Measure the tube size first, then match it to the sleeve table on page 32 in General Maintenance Items. A 10mm tube takes ZA93S10000, a 22mm tube takes ZA93S22000, and a 35mm tube takes ZA93S35000. Pull the matching nut from the same nut and sleeve list so both pieces fit the line you are rebuilding.
Manual Section: General Maintenance Items p. 32Filter element part numbers hard to confirm before a scheduled service interval comes due
Check the filter list in General Maintenance Items starting on page 25, then confirm each number against the parts number list on page 27. If you want every element in one order, cross-check the Element Kit listing in Tools and Spare Parts on page 455. Verify the machine name plate before you order.
Manual Section: General Maintenance Items p. 25Relief valve replacement part hard to identify among several set pressure variants
Open the relief valve listing in Hydraulic Components on page 634 and find the exact position you are replacing. Each variant has its own set pressure: F1 is 37.8MPa at 30L/min, F2 is 39.2MPa at 30L/min, and F6 is 29.4MPa at 190L/min. Order by that F code. Do not pick one because it looks the same.
Manual Section: Hydraulic Components p. 634Idler, roller, or rubber crawler belt part numbers unclear for a worn undercarriage
Inspect the chassis parts diagrams starting and locate the idler assy, roller assy, or shoe assy callout on the exploded view. Match that reference number to the parts list beside it. Check the name plate to confirm whether you are on the SK115SR-1E or SK115SRL-1E before ordering, because this book covers both.
Manual Section: UndercarriageBoom or arm hydraulic line part number hard to find after a burst hose on the attachment
Check the boom and attachment exploded views starting on page 424, then trace the failed line from the boom assy or arm assy callout to its reference number. Read the part number off the matching parts list. If a steel tube is involved, note the tube size and pull the correct sleeve from page 32.
Manual Section: Attachments p. 424Bucket or arm cylinder assembly part breakdown needed for a leaking cylinder
Check the general drawing on page 8 to confirm whether the leak is on the bucket cylinder or arm cylinder. Then go to the cylinder assy breakdowns in Hydraulic Components, which start on page 605. Match each callout on the exploded view to the parts list and record the numbers before you order.
Manual Section: Hydraulic Components p. 605Frequently Asked Questions
