No illustration for this section
The Relay Box Assembly is listed without an exploded view in the SK240-12 catalogue — the parts table below is the authoritative reference, and every part number is confirmed against your machine serial before we quote.
The Relay Box Assembly group on the Kobelco SK240-12 contains 15 separately 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.
