About this group

Ordering the 6.2M Boom Hydraulic Piping

The 29 entries group into 11 distinct number series, led by YN42H, LB42H. Expect repeated items such as clamp, tube, ring and 1 hardware positions when you work through it.

Where to start in this table: ZM73C12035 (sems bolt -, ×26 per assembly); YN64H01392D1 (cap, ×26 per assembly); YN42H02348P1 (clamp, ×6 per assembly). The full list follows below.

Send us the Kobelco SK260LC-12M serial number together with the part number or the symptom you are chasing. We confirm fitment from the serial range before quoting, and mixed orders are consolidated into a single shipment — a set of seals does not travel in its own parcel.

Hydraulic components are the heart of the Kobelco SK260LC-12M: main pump delivery, swing and travel drive, control valve sections and the lines and seals that connect them. When a circuit loses power, drifts under load, or runs noisy when warm, the fault is usually traced to one of the components in this group rather than to the machine as a whole.

FAQ

6.2M Boom Hydraulic Piping — common questions

Do you offer rebuilt or exchange pumps and motors?

We quote new components from this table — genuine or OEM by declaration — rather than exchange units, so you know exactly what is being fitted. In this group, ZM73C12035 is the number most often quoted for that enquiry.

What are the symptoms of a failing hydraulic component on the Kobelco SK260LC-12M?

Slow or drifting functions, a circuit that weakens as the oil warms, noise under load, and external leakage at joints are the usual reports. Pressure testing points to the circuit; the drawing callouts then point to the part.

Is the exploded view enough to identify my part?

Usually yes — the callout numbers on the drawing map directly to the Ref. column in the table. If your machine differs by serial range, send a photo of the part and we will confirm before quoting.
