Kobelco SK200-8 · Cylinder Assembly,Boom · 28 part numbers
No illustration for this section
The Cylinder Assembly,Boom is listed without an exploded view in the SK200-8 catalogue — the parts table below is the authoritative reference, and every part number is confirmed against your machine serial before we quote.
The Cylinder Assembly,Boom group on the Kobelco SK200-8 contains 28 separately orderable part numbers. The Ref. column mirrors the callout numbers on the illustration, so a part can be ordered straight from the drawing. Every entry is a genuine Kobelco part number, confirmed against the serial range before we quote.

Part numbers as fitted to the Kobelco SK200-8 excavator. Where a position changed during the production run, the serial number settles which one applies to your machine.
Structurally, these 28 numbers fall into 7 Kobelco number series — YN01V, 2438U, LP01V among the largest. Expect repeated items such as ring, repair, kit and 2 hardware positions when you work through it.
The high-quantity positions are: ZS23C16075 (capscrew, ×12 per assembly); YN01V01109P1 (bushing, ×4 per assembly); 2438U941S3 (seal,dust, ×4 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.
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. If that matches your case, quote ZS23C16075 and we will take it from there.
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.
Yes. Send the Kobelco SK200-8 serial number with the part number and we confirm the fit from the serial range. Where a component changed during the production run, we flag it before you commit.
