Kobelco SK200-8 · Idler Assembly · 9 part numbers

Illustration reproduced from the Kobelco SK200-8 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.
The Idler Assembly group on the Kobelco SK200-8 contains 9 separately orderable part numbers. The Ref. column mirrors the callout numbers on the illustration, so a part can be ordered straight from the drawing. The list comes straight from the Kobelco SK200-8 catalogue for this machine family.

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 9 numbers fall into 5 Kobelco number series — YN52D, 2405P, 2445R among the largest. The list is weighted toward repeated items such as idler, bushing, collar and 1 hardware positions.
The high-quantity positions are: 2405P482 (bushing, ×2 per assembly); YN52D01011P1 (collar, ×2 per assembly); 2445R442F1 (seal assy,floating, ×2 per assembly). The full list follows below.
Structural repairs are usually planned against measured wear rather than a fixed interval. Pins and bushings are the items to measure first; the retaining hardware in this group is cheap to replace at the same time and is worth adding to the same shipment.
The callout numbers on the exploded view map one-to-one to the Ref. column in the parts table. Identify the joint or component on the drawing, take its number from the table, and the quotation you receive will match the drawing exactly.
HD marks the heavy-duty version of the attachment, which uses its own pin and bushing part numbers that do not interchange with the standard version. Confirm which version the machine carries before ordering. If that matches your case, quote 2405P482 and we will take it from there.
Yes — hardware is the cheapest line in the order and the most expensive to revisit, so a joint rebuild normally includes fresh clips, shims and bolts.
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.
