Factory part numbers as fitted to the Kobelco SK330-8 excavator. "Ref." matches the callout number on the exploded view where one is shown.
Structurally, these 16 numbers fall into 5 Kobelco number series — YT30V, 2436U, YN30V among the largest. The list is weighted toward repeated items such as spring, plate, seat and 3 hardware positions.
Where to start in this table: 2436U1277S211 (plug, ×4 per assembly); 2436U2938S212 (rod,push, ×4 per assembly); 2436U1277S213 (seal, ×4 per assembly). The full list follows below.
Rebuild-at-component-level is the practical route for most Kobelco SK330-8 hydraulic assemblies. Wear shows up at predictable points — spool clearances, valve plates, bearing sets, seal packages — and those items are listed individually, so you can quote only what is worn instead of exchanging the complete unit.
Seal kits for this group are quoted from the same table — the O-ring and seal positions carry their own numbers, so a hydraulic repair never forces a purchase at assembly level.
In most cases yes. The wear points on Kobelco SK330-8 hydraulic assemblies are individually replaceable and all carry their own part numbers in the table above, so a targeted repair can be quoted without exchanging the complete unit. In this group, 2436U1277S211 is the number most often quoted for that enquiry.
Stocked items leave within one to two working days. Anything that needs ordering through supply channels is quoted with a lead time upfront, and mixed orders are consolidated for dispatch to 30+ countries.
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.
