Kobelco SK015 Parts Manual (P/N PU02001)

Planning a hydraulic pump repair or rebuilding the undercarriage on a Kobelco SK015? This parts catalog covers the PU02001 and up serial range, with assembly drawings, part numbers, quantities, and application notes.

The 277-page PDF is image-based and has no searchable text layer.

• Hydraulic components: Control valve and pump-drive breakdowns, swivel-joint components, cylinder parts lists, and separate pilot-valve assemblies.

• Undercarriage: Front idler, lower roller, track adjuster, travel device, driving sprocket, and steel or rubber crawler-shoe parts identification.

• Slew and digging equipment: Slewing device, turntable, boom swing, arm-and-link assemblies, and bucket drawings with itemized pins, bushings, and shims.

• Engine components: Internal engine assembly drawings, fuel-injection equipment, governor, lubrication and cooling systems, starting motor, and generator parts lists.

• Operator station: Cabin structure, canopy and seat assemblies, control levers, blade control mechanisms, and swing/service pedal hardware.

• Electrical components: Harness layouts, relay and fuse assemblies, lighting, instrument panel, and battery installation drawings for component identification.

This catalog is suited to mechanics and experienced owners who can match drawing callouts and serial-number notes to the machine before ordering repair parts.

Serial Breaks and Cab/Canopy Differences

The lever-stand drawings separate PU02001–PU02318 from PU02319 onward. Hydraulic tank and track-adjuster grease-cylinder listings also change at PU02319; the swivel-joint entries distinguish assemblies before and from PU02109.

The operator-station sections distinguish Japan-market multi-control arrangements, European cab components, and the R.O.P.S. canopy for the USA. Cab and canopy swing cylinders use different piston rods and seal kits, helping you identify the correct kit for a cylinder repair before ordering.

Hydraulic Parts and Catalog Limitations

Separate Pilot Valve drawings identify S19017-21100 and S19017-21500. Cylinder tables list packing, wear rings, seals, and kit contents, while hydraulic tank systems and fuel piping drawings identify lines, fittings, and mounting hardware.

The Hydraulic Pump entry lists the pump assembly, packings, oil seal, snap ring, and seal kit. Its illustration has callout numbers that do not match the accompanying parts table.

The Travel Device table also prints an inverted serial range for motor S19031-14300. These entries require confirmation against the fitted component before parts are ordered.

Undercarriage and Attachment Options

Travel-device listings distinguish left- and right-hand motors and versions marked “with P.B.” or “without P.B.” Separate slew- and travel-motor sections provide internal component and seal-kit references, including sectional views.

The arm listings distinguish 930 mm and 1,130 mm assemblies, with separate hose entries for the long arm. Bucket sections identify different widths and tooth arrangements, while the crawler-shoe section separates steel tracks from the rubber-track replacement listing.

3TNA72L-UT88 Engine and Filter Listings

Need to cross-reference engine components? The 3TNA72L-UT88 listings cover the cylinder block, cylinder head and bonnet, crankshaft and piston, and camshaft and driving gear. Oversize piston/ring assemblies and undersize main and crankpin bearings have separate part entries.

Fuel-injection pump, governor, and injection-valve drawings identify their subcomponents. Hardware descriptions include fastener sizes, shim thicknesses, and seal designations for parts identification.

Maintenance consumables include engine oil, fuel, and air filters, the water separator, hydraulic return-filter cartridge, and suction strainer element.

Parts Identification and Repair Scope

The catalog does not provide troubleshooting, hydraulic pressure-test procedures, torque tables, wear limits, or step-by-step overhaul instructions. Electrical pages show harness and component layouts rather than circuit schematics.

Safety Note: This manual is strictly for component identification and ordering. Always reference the corresponding factory service manual for torque specs, lifting procedures, and safe teardown steps before starting heavy machine repairs.

File Format and Readability

The page count includes one cover page, three Figure Search index pages, and 273 pages of catalog entries.

Two PDF bookmarks open the cover and Figure Search index; individual assemblies are not bookmarked, and the index is not clickable. Small drawing callouts can require zooming, and fine text in some decal reproductions remains blurred when enlarged.
