Kobelco SK200-10 · Arm Assembly (Hydraulic Crusher & Breaker) · 22 part numbers
No illustration for this section
The Arm Assembly (Hydraulic Crusher & Breaker) is listed without an exploded view in the SK200-10 catalogue — the parts table below is the authoritative reference, and every part number is confirmed against your machine serial before we quote.
The Arm Assembly (Hydraulic Crusher & Breaker) group on the Kobelco SK200-10 contains 22 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 SK200-10 excavator. Where a position changed during the production run, the serial number settles which one applies to your machine.
Structurally, these 22 numbers fall into 6 Kobelco number series — YN12B, B16T, ZG91S among the largest. The list is weighted toward repeated items such as shim, link, pin and 2 hardware positions.
The high-quantity positions are: 2445R220D4 (seal, dust, ×6 per assembly); ZG91S02000 (nipple, grease, ×5 per assembly); ZN18C20016 (nut, ×4 per assembly). The full list follows below.
Rebuild-at-component-level is the practical route for most Kobelco SK200-10 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.
Seal kits for this group are quoted from the same table — the O-ring and seal positions carry their own numbers, so a hydraulic repair never forces a purchase at assembly level.
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 2445R220D4 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 SK200-10 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.
