The 14 entries group into 3 distinct number series, led by YN22V, ZD12P. The list is weighted toward repeated items such as ring, spring, back and 2 hardware positions.

Where to start in this table: ZD12P02400 (o-ring, ×1 per assembly); ZD12P02240 (o-ring, ×1 per assembly); YN22V00001S521 (spring, ×1 per assembly). The full list follows below.

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.

Hydraulic components are the heart of the Kobelco SK250-8: main pump delivery, swing and travel drive, control valve sections and the lines and seals that connect them. When a circuit loses power, drifts under load, or runs noisy when warm, the fault is usually traced to one of the components in this group rather than to the machine as a whole.
