Kobelco SK240-12 · Valve Mounting (Hydraulic Crusher & Breaker) · 40 part numbers

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 Valve Mounting (Hydraulic Crusher & Breaker) group on the Kobelco SK240-12 contains 40 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 40 numbers fall into 14 Kobelco number series — YN30V, ZD12P, 2436U among the largest. Expect repeated items such as ring, spring, valve and 10 hardware positions when you work through it.
Where to start in this table: HS28C12170G1 (capscrew, ×4 per assembly); ZS23C08025 (capscrew, ×4 per assembly); PX64H01010D1 (cap, ×2 per assembly). The full list follows below.
Swing, travel and implement circuits share the same pump flow on the Kobelco SK240-12, which is why a fault in one function can point back to a component listed in this group. A pressure test narrows the circuit down; the drawing then narrows it to a part number.
Working from the exploded view is the fastest way to order. Find the component on the drawing, note its callout number, and take the matching reference from the table — that mapping removes the guesswork that comes with describing a part over the phone or in an email.
In most cases yes. The wear points on Kobelco SK240-12 hydraulic assemblies are individually replaceable and all carry their own part numbers in the table above, so a targeted repair can be quoted without exchanging the complete unit. In this group, HS28C12170G1 is the number most often quoted for that enquiry.
Stocked items leave within one to two working days. Anything that needs ordering through supply channels is quoted with a lead time upfront, and mixed orders are consolidated for dispatch to 30+ countries.
It is the quantity fitted per assembly in the catalogue — useful when a job calls for more than one of the same part, such as O-rings fitted in a pack.
