Illustration reproduced from the Kobelco SK240-12 parts catalogue for part identification only. Callout numbers on the drawing match the Ref. column in the table below. Kobelco is a trademark of its respective owner; Shenyue Machinery is an independent supplier of excavator parts.
The Stopper Control Piping (Sensor Group) group on the Kobelco SK240-12 contains 25 separately orderable part numbers. Callout numbers on the exploded view map one-to-one to the Ref. column in the table. All numbers are taken from the machine's own parts catalogue — nothing here is generic.

Factory part numbers as fitted to the Kobelco SK240-12 excavator. "Ref." matches the callout number on the exploded view where one is shown.
Structurally, these 25 numbers fall into 15 Kobelco number series — YN21C, 2420R, YN64H among the largest. The list is weighted toward repeated items such as hose, clip, control and 6 hardware positions.
Where to start in this table: ZM73C12025 (sems bolt -, ×7 per assembly); YN13E01375P1 (clip, ×5 per assembly); ZH22X06000 (connector, ×4 per assembly). The full list follows below.
Where no illustration exists for this section, the parts table below is the authoritative list — the callout numbering refers to the machine's own catalogue, and every entry is a real Kobelco part number.
Monitor and controller items vary by machine build, so the serial number matters more in this group than in most. Send it with the fault description and we confirm the correct variant before quoting.
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. In this group, ZM73C12025 is the number most often quoted for that enquiry.
Yes — electrical items are compact and consolidate easily into an existing shipment.
By part number — the catalogue lists harness sections as complete numbered items, and that is how we quote them.
