About this group

Ordering the Cylinder Assembly,Arm

Read as a dataset, the 37 part numbers spread across 9 number series (LQ01V, 2438U, LB01V being the biggest) The list is weighted toward repeated items such as ring, repair, kit and 3 hardware positions.

The high-quantity positions are: ZS23C20080 (capscrew, ×10 per assembly); LC12B01494P1 (bushing, ×4 per assembly); 2438U1381S24 (ring,wiper, ×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 Cylinder Assembly,Arm group on the Kobelco SK250-8 contains 37 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.

FAQ

Cylinder Assembly,Arm — common questions

What does the QTY column mean?

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 ZS23C20080 and we will take it from there.

Do you supply genuine or OEM hydraulic parts?

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.

Do you offer rebuilt or exchange pumps and motors?

We quote new components from this table — genuine or OEM by declaration — rather than exchange units, so you know exactly what is being fitted.
