Kobelco SK240-12 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 12 entries group into 5 distinct number series, led by YN40F, 2425T. Expect repeated items such as ring, slewing, race and 1 hardware positions when you work through it.
If you are quoting from this group, start with: 2425T307 (ball, ×120 per assembly); YN40F01018P1 (retainer, ×120 per assembly); YN40F01001P1 (capscrew, ×36 per assembly). The full list follows below.
If the item you need sits between two groups, send us the part number — our catalogue coverage for the Kobelco SK240-12 runs across every group, and this page is only one of them.
We hold over 3,000 part types on the shelf in Guangzhou, with more than 100,000 part numbers available to order through original supply channels — so if the item you need is not on this page, send us the number and we will source it.
Send us the part number or a photo. This page covers one group of the Kobelco SK240-12; our parts coverage runs across the whole machine and the wider Kobelco range. The practical first number to ask for in this group is 2425T307.
Photos speed up identification, but the order is always confirmed against a part number — the photo gets us there faster.
Both are available and the condition is declared on every line of the quotation — genuine via original supply channels, or a quality OEM alternative.
