Part numbers as fitted to the Kobelco SK250-8 excavator. Where a position changed during the production run, the serial number settles which one applies to your machine.
Read as a dataset, the 35 part numbers spread across 15 number series (VH111, VH906, VH963 being the biggest) In practice that means repeated items such as head, cyl, bolt and 13 hardware positions.
The high-quantity positions are: VH111221220A (bushing,valve guide, ×16 per assembly); VH125051101A (silent block sub assy, ×13 per assembly); VH906808400A (bolt,flange, ×13 per assembly). The full list follows below.
Cooling-system items in this group are the usual first suspects for overheating under load. Cores, hoses, clamps and the water-side hardware are all separately orderable, which keeps a cooling repair proportionate to the fault.
Cooling and fuel-system faults on the Kobelco SK250-8 usually show up as overheating under load, hard starting, or loss of power. Because each component in this group is separately orderable, the repair can be scoped to the parts actually involved instead of a wholesale exchange.
Yes for engine-maker cross-referenced items — the cross-references in the table let us quote from the engine nameplate number directly. If that matches your case, quote VH111221220A and we will take it from there.
Send the machine serial number and the engine number from the nameplate. Several components changed across the production run, and both numbers together confirm the correct set.
Both are useful — the machine serial confirms the build and the engine nameplate number confirms engine-mounted items. Send both and we match them.
