Kobelco SK260LC-12M excavator part numbers, taken from the machine's own parts catalogue. Items shared with neighbouring machine generations are confirmed from your model plate before quoting.
The 24 entries group into 14 distinct number series, led by LC52D, LB52D. The list is weighted toward repeated items such as idler, pin, crawler and 3 hardware positions.
If you are quoting from this group, start with: LB52D00039F1 (idler assy, crawler, ×2 per assembly); LC52D01040P1 (collar, ×2 per assembly); LC52D01019P1 (bushing, ×2 per assembly). The full list follows below.
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.
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.
Yes. Send the serial number and which joints are loose, and we assemble the pin, bushing and hardware list into one quotation with everything consolidated into a single shipment. The practical first number to ask for in this group is LB52D00039F1.
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.
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.
