Listed for the Kobelco SK200-10 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 23 numbers fall into 14 Kobelco number series — YN42H, ZS18C, ZS28C among the largest. Expect repeated items such as capscrew, hyd, lines and 7 hardware positions when you work through it.
Three numbers worth noting first: ZS28C12040 (capscrew, ×4 per assembly); ZS28C14050 (capscrew, ×4 per assembly); ZW26K14000 (lock washer, ×4 per assembly). The full list follows below.
Rebuild-at-component-level is the practical route for most Kobelco SK200-10 hydraulic assemblies. Wear shows up at predictable points — spool clearances, valve plates, bearing sets, seal packages — and those items are listed individually, so you can quote only what is worn instead of exchanging the complete unit.
Seal kits for this group are quoted from the same table — the O-ring and seal positions carry their own numbers, so a hydraulic repair never forces a purchase at assembly level.
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 Kobelco SK200-10, that usually comes back to ZS28C12040 (capscrew) 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.
