No illustration for this section
The Alternator is listed without an exploded view in the SK250-8 catalogue — the parts table below is the authoritative reference, and every part number is confirmed against your machine serial before we quote.
The Kobelco SK250-8 Alternator breaks down into 35 individually orderable part numbers. Callout numbers on the exploded view map one-to-one to the Ref. column in the table. Every entry is a genuine Kobelco part number, confirmed against the serial range before we quote.

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.
The 35 entries group into 7 distinct number series, led by VH273, VH274. In practice that means repeated items such as alternator, bolt, through and 9 hardware positions.
The high-quantity positions are: VH273171650A (bolt,through, ×4 per assembly); VH273831330A (insulator,holder brush, ×4 per assembly); VH273891310A (insulator,terminal, ×4 per assembly). The full list follows below.
Each component carries its own Kobelco part number, from the assembly level down to individual connectors and relays. Working from the drawing callouts and the Ref. column keeps the diagnosis and the order aligned.
Connector and terminal items in this group are the small parts that end most wiring repairs. They are inexpensive, so they are worth adding to any order as spares for the same machine.
Yes — the harness is listed alongside its individual components, so you can replace a section or the complete assembly from the same table. If that matches your case, quote VH273171650A and we will take it from there.
Send us the part number or a photo. Our coverage runs to 100,000+ part numbers available to order — this page lists one group, not the whole machine.
Yes. Connectors, relays and switches all carry their own part numbers in the table above, so a single connector repair can be quoted without a harness.
