Illustration reproduced from the Kobelco SK200-10 parts catalogue for part identification only. Callout numbers on the drawing match the Ref. column in the table below. Kobelco is a trademark of its respective owner; Shenyue Machinery is an independent supplier of excavator parts.
26 separately orderable part numbers make up the Track Idler Assembly — Group 2 on the Kobelco SK200-10. Where the drawing shows a callout, the Ref. column in the table carries the same number. The list comes straight from the Kobelco SK200-10 catalogue for this machine family.

Factory part numbers as fitted to the Kobelco SK200-10 excavator. "Ref." matches the callout number on the exploded view where one is shown.
Read as a dataset, the 26 part numbers spread across 14 number series (YN52D, YN54D, 2445R being the biggest) In practice that means repeated items such as idler, ring, pin and 3 hardware positions.
Where to start in this table: YN52D00117F1 (idler assy, crawler, ×2 per assembly); 2405P482 (bushing, ×2 per assembly); YN52D01065P1 (collar, ×2 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.
We supply genuine parts ordered through original supply channels, and quality OEM alternatives where that is the practical choice. The condition of every item is declared on the quotation. In this group, YN52D00117F1 is the number most often quoted for that enquiry.
If the boom, arm or bucket was changed after delivery, tell us the attachment part number as well as the machine serial — the numbers must match the attachment actually fitted.
On several Kobelco SK200-10 variants they do — pin and bushing part numbers changed with the attachment configuration. Send the serial number and we confirm the correct group before quoting.
