Kobelco SK300LC Mark IV Excavator Parts Catalog PDF

Get the part numbers and assembly diagrams for your Kobelco SK300LC Mark IV excavator. This illustrated parts catalog covers serial numbers YCU0603, YCU0607, and YCU0611 onward, with configuration notes alongside the component listings.

• OEM filter references: Engine oil filter YN50VU0001D5, fuel filter YN50VU0001D3, hydraulic filters, tank breathers, and air-cleaner elements are identified by application.

• Hydraulic assemblies: Hydraulic-line routing, pump and regulator breakdowns, swing motors, pilot control valves, swivel valves, relief and solenoid valve section views, and cylinder repair-kit listings.

• Undercarriage: Travel reduction units, track rollers, idlers, and track adjusters, with separate illustrations for short, long, high-and-wide, and T-Mar crawler configurations.

• Engine installation: Cummins engine configuration references, power take-off assemblies, engine mounts, fuel-system components, radiator installations, and cooling-system connections.

• Cab and electrical equipment: Seating groups, floor-plate variants, control boxes, operator control levers, instrument-panel components, and wiring-harness layouts with connector views.

• Attachments: Standard and mass-excavator boom and arm assemblies, Hendrix buckets and teeth, nibbler and breaker lines, thumb controls, and boom/arm safety-valve installations.

This catalog is suited to mechanics and parts staff who can match illustrated assemblies and configuration notes to the equipment installed on a machine.

Hydraulic Pumps, Swing Motors, and Travel Drives

The Swing Motor Assy, Travel Reduction Assy, and Hydraulic Control Valve Assy drawings show internal components and their relationship to the parts lists. Selected assemblies include component specifications and assembly notes; the catalog supports parts identification for repair work. It does not provide a complete workshop repair sequence.

Pump coverage: The 2437U472F3 assembly lists its pump, regulator, and solenoid valve, but refers the individual component parts lists to a dealer.

Configuration notes link the E.C. engine LC02PU0001F1 to hydraulic pump 2437U472F2 and CPU 2480U393F6. That pairing helps a shop check the engine, pump, and controller combination before ordering a replacement for an E.C. machine.

Counterweight, Cab, and Attachment Details

Upper-frame, hydraulic-tank, and fuel-tank drawings identify mounting hardware and associated components. The counterweight illustration identifies lifting hardware, but does not provide a step-by-step removal and installation procedure.

Cab installation drawings separate seating groups and floor-plate configurations. The operator control lever and control-box listings help distinguish the hardware used around the operator’s station.

Bucket and arm compatibility: Hendrix bucket listings distinguish tooth options, and the attachment notes warn that an unsuitable bucket can severely damage the attachments. The long-arm configuration calls for the Bucket Cut Circuit. Mass-excavator reinforcement welding is referred to separate dealer instructions.

Safety note: Use this catalog for component identification and reference. Heavy lifting and hydraulic service require qualified technicians and appropriate shop procedures.

Cummins References and Wiring-Harness Repair Parts

Cummins option specifications identify engine build configurations; detailed engine parts data is referred to a separate Cummins Engine Parts Manual.

The Electrical Wiring Assy, Instrument Panel Harness Assy, and Controller Harness Assy illustrations show harness routing and connector arrangements. A local wiring detail accompanies the Bucket Cut Circuit, while the complete electrical schematic 24101J516 is listed as a separate item and is not reproduced.

Harness repair components: Master repair kit 24100J18668F1 is described as containing 3,777 pieces across 137 different items. Its listings identify connectors, terminals, seals, a release tool, and wire-stripping and crimping tools.

Metric/inch hardware-conversion tables and hydraulic-line spanner listings supplement the assembly references.

Selected Tool Fitments and Track Shoe Sizes

These examples are a small sample of the catalog’s component-sizing and fitment data.

Special spanner 2421T160 is listed for 15 mm tubing, while 2421T314 is listed for 35 mm tubing.

For the long crawler, track assembly 24100J15219F8 uses 700 mm double-bar shoes; 24100J15219F9 uses 800 mm double-bar shoes.

PDF Navigation and Page Breakdown

Text search and drawing detail: Part-number tables and figure headings are searchable; labels within drawings are not. Five bookmarks cover the file’s main sections, without individual assembly bookmarks. Small wiring labels require magnification, and some fine lines and markings remain faint.

One printable 445-page PDF in English, with some English/Spanish drawing labels. The total includes 436 catalog pages, four figure-index pages, one search-instruction page, two hardware-conversion pages, one supplementary page, and one blank page.
