About this group

Ordering the Hyd Lines,Upp (Main)

Read as a dataset, the 41 part numbers spread across 14 number series (LQ03H, YN03H, ZD12P being the biggest) The list is weighted toward repeated items such as hose, ring, clamp and 12 hardware positions.

If you are quoting from this group, start with: HM83C10035G1 (sems-bolt, ×48 per assembly); ZE12X16000 (clamp,half, ×20 per assembly); ZD12P03400 (o-ring, ×12 per assembly). The full list follows below.

For workshops planning a full hydraulic health check, the practical sequence is seals first, then wear items such as valve plates and bushings, and only then complete assemblies. The table below supports that sequence because every level of the breakdown is separately orderable.

Rebuild-at-component-level is the practical route for most Kobelco SK250-8 hydraulic assemblies. Wear shows up at predictable points — spool clearances, valve plates, bearing sets, seal packages — and those items are listed individually, so you can quote only what is worn instead of exchanging the complete unit.

FAQ

Hyd Lines,Upp (Main) — common questions

What are the symptoms of a failing hydraulic component on the Kobelco SK250-8?

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. The practical first number to ask for in this group is HM83C10035G1.

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.

Can you match a part to a machine serial directly?

Yes — send the serial and the part number together; where a position changed across the run we flag it and quote the number that matches your build.
