Below is the complete Kobelco SK250-8 Valve System — 24 part numbers with the quantity fitted per assembly. Where the drawing shows a callout, the Ref. column in the table carries the same number. The list comes straight from the Kobelco SK250-8 catalogue for this machine family.

Kobelco SK250-8 excavator part numbers, taken from the machine's own parts catalogue. Items shared with the closely related SK260LC-8 and the later SK250-10 generation are confirmed from your model plate before quoting.
Structurally, these 24 numbers fall into 6 Kobelco number series — VH137, VH139, VH906 among the largest. The list is weighted toward repeated items such as valve, rocker, sub and 7 hardware positions.
If you are quoting from this group, start with: VH900126122A (lock,valve spg retainer, ×32 per assembly); VH137191470A (seal,valve stem oil, ×16 per assembly); VH137311610A (spring,valve,outer, ×16 per assembly). The full list follows below.
Engine-side work on the Kobelco SK250-8 is planned either by symptom or by service hours. Both routes end at the same table: the symptom or the service item maps to a callout, the callout maps to a part number, and the quotation follows.
Working from the exploded view keeps ordering precise: find the component on the drawing, note the callout number, and match it to the Ref. column in the table. Where no illustration exists for this section, the parts table below is the authoritative list.
Hoses, clamps and caps are straightforward; cores and complete assemblies are heavier work. We supply the parts either way. The practical first number to ask for in this group is VH900126122A.
Both. Assemblies are listed alongside their internal components, so a targeted repair and a full exchange are quoted from the same table.
Always. Genuine via original supply channels or quality OEM alternative is stated on the quotation for every line item.
