Listed for the Kobelco SK200-8 excavator. Every number can be quoted on its own or as a complete set, and fitment is confirmed from your machine serial before we price it.
Structurally, these 16 numbers fall into 5 Kobelco number series — YT30V, 2436U, YN30V among the largest. In practice that means repeated items such as spring, plate, seat and 3 hardware positions.
Three numbers worth noting first: 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 SK200-8 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 SK200-8 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.
Both. Every quotation states the condition of each item — genuine through original supply channels, or a quality OEM alternative — so the choice is yours and it is documented. On the SK200-8, that usually comes back to 2436U1277S211 (plug) in this group.
We quote new components from this table — genuine or OEM by declaration — rather than exchange units, so you know exactly what is being fitted.
Slow or drifting functions, a circuit that weakens as the oil warms, noise under load, and external leakage at joints are the usual reports. Pressure testing points to the circuit; the drawing callouts then point to the part.
