Part numbers as fitted to the Kobelco SK330-8 excavator. Where a position changed during the production run, the serial number settles which one applies to your machine.
Read as a dataset, the 35 part numbers spread across 14 number series (LB15V, LC15V, EZ15V being the biggest) The list is weighted toward repeated items such as plate, plug, ring and 6 hardware positions.
The high-quantity positions are: LB15V00011S712 (spring, ×14 per assembly); ZS23C20045 (capscrew, ×4 per assembly); LB15V00011S743 (plate,separator, ×4 per assembly). The full list follows below.
Every hydraulic item we quote is declared by condition: genuine, ordered through original supply channels, or a quality OEM alternative. The declaration appears on the quotation itself, never buried in an invoice, so you know exactly what you are fitting before you commit.
The Motor Assembly (Swing) group on the Kobelco SK330-8 contains 35 separately orderable part numbers, all listed in the table below with the quantity fitted per assembly. Every number in the table is a real Kobelco part number taken from the machine's own parts catalogue, not a generic cross-reference.
It is the quantity fitted per assembly in the catalogue — useful when a job calls for more than one of the same part, such as O-rings fitted in a pack. If that matches your case, quote LB15V00011S712 and we will take it from there.
Both. Every quotation states the condition of each item — genuine through original supply channels, or a quality OEM alternative — so the choice is yours and it is documented.
We quote new components from this table — genuine or OEM by declaration — rather than exchange units, so you know exactly what is being fitted.
