About this group

Ordering the Motor Assembly (Swing)

Read as a dataset, the 36 part numbers spread across 11 number series (YN15V, ZE82T, YN22V being the biggest) In practice that means repeated items such as plate, plug, ring and 7 hardware positions.

If you are quoting from this group, start with: YN15V00025S712 (spring, ×18 per assembly); ZS23C20045 (capscrew, ×4 per assembly); YN15V00025S743 (plate,separator, ×4 per assembly). The full list follows below.

Hydraulic components are the heart of the Kobelco SK200-8: 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.

Swing, travel and implement circuits share the same pump flow on the Kobelco SK200-8, 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.

FAQ

Motor Assembly (Swing) — common questions

What are the symptoms of a failing hydraulic component on the SK200-8?

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 YN15V00025S712.

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.
