Read as a dataset, the 38 part numbers spread across 10 number series (LQ15V, 2441U, PH15V being the biggest) The list is weighted toward repeated items such as ring, plate, piston and 5 hardware positions.

The high-quantity positions are: LQ15V00015S013 (spring, ×19 per assembly); LQ15V00015S018 (lock washer, ×4 per assembly); LQ15V00015S019 (ring, ×4 per assembly). The full list follows below.

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.

Swing, travel and implement circuits share the same pump flow on the Kobelco SK250-8, which is why a fault in one function can point back to a component listed in this group. A pressure test narrows the circuit down; the drawing then narrows it to a part number.
