Factory part numbers as fitted to the Kobelco SK250-8 excavator. "Ref." matches the callout number on the exploded view where one is shown.
Structurally, these 16 numbers fall into 5 Kobelco number series — YT30V, 2436U, YN30V among the largest. The list is weighted toward repeated items such as spring, plate, seat and 3 hardware positions.
Where to start in this table: 2436U1277S211 (plug, ×4 per assembly); 2436U2938S212 (rod,push, ×4 per assembly); 2436U1277S213 (seal, ×4 per assembly). The full list follows below.
The Valve Assembly,Pilot group on the Kobelco SK250-8 contains 16 separately orderable part numbers, all listed in the table below with the quantity fitted per assembly. Every number in the table is a real Kobelco part number taken from the machine's own parts catalogue, not a generic cross-reference.
Send us the Kobelco SK250-8 serial number together with the part number or the symptom you are chasing. We confirm fitment from the serial range before quoting, and mixed orders are consolidated into a single shipment — a set of seals does not travel in its own parcel.
In most cases yes. The wear points on Kobelco SK250-8 hydraulic assemblies are individually replaceable and all carry their own part numbers in the table above, so a targeted repair can be quoted without exchanging the complete unit. In this group, 2436U1277S211 is the number most often quoted for that enquiry.
Stocked items leave within one to two working days. Anything that needs ordering through supply channels is quoted with a lead time upfront, and mixed orders are consolidated for dispatch to 30+ countries.
It is the quantity fitted per assembly in the catalogue — useful when a job calls for more than one of the same part, such as O-rings fitted in a pack.
