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.
Read as a dataset, the 12 part numbers spread across 8 number series (2444R, YN02B, ZH32Z being the biggest) In practice that means repeated items such as hose, clip, boom and 4 hardware positions.
The high-quantity positions are: ZG91S02000 (nipple, grease, ×8 per assembly); YT02C01888P2 (sems bolt -, ×4 per assembly); ZC48X10009 (clip, ×3 per assembly). The full list follows below.
Rebuilding a joint takes the machine out of service once, so it pays to consolidate: pins, bushings, retaining rings and the joint seals quoted together, arriving as one kit rather than in several parcels.
Undercarriage and structural wear is progressive: play at a joint, a knocking sound on direction change, oval wear on a pin. Because each position carries its own part number, worn positions can be replaced individually instead of ordering the complete group.
They are the catalogue quantities per assembly — the number of that item fitted to one complete group, which is exactly how a rebuild order is planned. If that matches your case, quote ZG91S02000 and we will take it from there.
Compact heavy items such as pins travel by air or courier; larger sections go by sea with crating and bracing. Freight is quoted separately so the landed cost is visible upfront.
Yes — retaining rings, shims and bolts are all listed in this group, and a joint rebuild quotation includes them by default.
