About this group

Ordering the Valve Assembly,Swing-Reactionless

Structurally, these 15 numbers fall into 8 Kobelco number series — YN20V, ZD12P, LQ15V among the largest. The list is weighted toward repeated items such as ring, valve, case and 2 hardware positions.

Three numbers worth noting first: ZS23C08055 (capscrew, ×4 per assembly); YW30V00001S157 (plug, ×2 per assembly); ZD12P01100 (o-ring, ×2 per assembly). The full list follows below.

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.

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.

FAQ

Valve Assembly,Swing-Reactionless — common questions

Do you supply genuine or OEM hydraulic parts?

Both. Every quotation states the condition of each item — genuine through original supply channels, or a quality OEM alternative — so the choice is yours and it is documented. On the Kobelco SK200-8, that usually comes back to ZS23C08055 (capscrew) in this group.

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.

What are the symptoms of a failing hydraulic component on the Kobelco 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.
