Replacing a slewing ring or a radiator on the Kobelco SK100W-2 excavator starts with the right part number, and this 666-page factory catalog, OEM ID YE03-02001, lists those numbers group by group. Exploded views in the Kobelco SK100W-2 parts catalog PDF break down the Upper, Cab & Guard, Control, Hyd & Air Lines, Power Plant, Electric, Lower and Attachment groups, with instrument panel and controller harnesses shown separately. Hydraulic components and engine parts follow, from main relief and pilot valve assemblies to the cylinder head, crankshaft and liner and piston kit, plus optional 2.27M and 2.77M arms, buckets from 0.17M to 0.51M, and name plate and tool listings. Match the main relief valve to its listed 20.6 MPa at 210 L/min. Your job may be an engine overhaul and its gasket kit. Bookmarks put you in the right group within a couple of clicks, and the text layer lets you search any part name or number.

Kobelco SK100W-2 Common Problems This Manual Covers
Kobelco SK100W-2 main harness assembly replacement, three part numbers listed and unsure which fits my serial
Check your serial plate against the harness assembly parts list on page 183. Order 24100J19291F1 for YE03-02001 to 02105, 24100U19291F2 for YE03-02106 to 02200, and 24100J19291F3 for YE03-02201 onward. Confirm the sub-harnesses (engine sub, lower, boom) on the same list before ordering.
Manual Section: Electric Group p. 183Horn assembly part number does not match the original on later serial number machines
Check your serial number before ordering the horn from the harness parts list on page 183. Machines YE03-02001 to 02424 take 2479U1009F1 and 2479U1009F2. From YE03-02425 onward the book lists CM53S00002F1 and CM53S00002F2. Verify which of the two horn positions you are replacing so you order the right item.
Manual Section: Electric Group p. 183Starter motor replacement part number needed, unsure which 24V starter assembly fits the engine
Check the engine parts list on page 634 for the starter assembly. It lists ME080740 as the 24V 5.0KW starter, applicable to all units. If the battery relay is also suspect, pull its number from the harness list on page 183: relay, battery 2479R1470F3. Order both together to save a second wait.
Manual Section: Engine Parts p. 634Relief valve assembly part number unclear, several relief valves listed with different set pressures
Compare the set pressure your circuit calls for against the hydraulic component lists before ordering. Valve assy, relief 2436R680F1 on page 364 runs from 4.22MPa at 17L/min (F1) to 11.77MPa at 20L/min (F4). Valve assy, relief 2436R683F1 on page 366 runs from 30.9MPa at 30L/min to 34.3MPa at 50L/min. Confirm the F code.
Manual Section: Hydraulic Components p. 364Main relief valve listed in several F code variants, unsure which set pressure version to order
Check the main relief valve listing on page 381 and identify the F code before ordering. F1 sets at 20.6MPa at 210L/min, F2 at 20.6MPa at 100L/min, F3 at 27.5MPa at 90L/min and F4 at 27.5MPa at 50L/min. Cross-check the second main relief listing on page 376, where F3 sets at 28.4MPa at 20L/min.
Manual Section: Hydraulic Components p. 381Battery, starter and earth cable part numbers hard to find among the electric group harness parts
Check the harness assembly parts list on page 183 for the main cables: starter cable 2486R90D1, battery cable YN13E01053D1, battery relay cable 2486R83F2 and earth cable 2486R87D1. Then check page 184 for the engine earth cable, listed as 2486R190D1. Order by item number so the lengths match your harness routing.
