2001– Kobelco SK135SRLC Short Radius Excavator Parts Catalog

This Kobelco SK135SRLC short radius excavator parts catalog covers machines from serial number YH01-00101. Shared assembly lists also carry YY01-series applicability notes, with serial breaks identifying changes in individual components.

Text search and drawing detail: The figure index, headings and populated parts tables are searchable; many labels within drawings are not. Five bookmarks open the index, introductory material and catalog start. Small connector and wire-code labels in the harness drawing require zooming.

• Engine components: Illustrated parts breakdowns for the cylinder head, block, crankshaft, pistons, valve train, lubrication system and turbocharger.

• Fuel and cooling: Injection-system parts, Zexel feed-pump components, fuel filters, radiator assemblies, water-pump parts and thermostat housings.

• Hydraulic assemblies: Pump and motor drawings, main control and pilot valves, swivel-joint views, hydraulic reservoirs and configuration-specific hose routing.

• Undercarriage: Crawler idlers, track adjusters, upper and lower rollers, track links, shoe assemblies and slewing-ring components.

• Electrical and cab: Engine electrical parts, MECHA-TRO controllers, wiring-harness and connector views, instrument panels, cab hardware and air-conditioning components.

• Boom, arm and bucket: Attachment assemblies, pins, bushings and shims, plus separate rod-side and piston-side cylinder repair kits.

This catalog is suited to parts staff and mechanics who can match machine serial numbers and installed assemblies to illustrated parts lists.

Engine Parts and Serial Changes

Engine assembly listings change at YH01-00654 and YY01-01530; governor-motor listings change at YH01-00503 and YY01-01043. These distinctions help identify the applicable assembly before replacement parts are ordered for a repair.

The engine pages distinguish cylinder-liner grades and AX/CX piston variants. Gasket sets, crankshaft bearings, intake and exhaust parts, oil-cooler components and turbocharger hardware are listed separately.

Fuel-injection coverage includes a North America pump listing, nozzle components, the Zexel feed pump and injection-pump coupling. Cooling-system drawings identify radiator mounting parts, the water pump and fan-drive hardware.

Hydraulic Components and Seal Kits

The YY30V00005 control-valve section includes sectional views, spool identification and parts tables. Boom, arm, bucket, travel and confluence functions are labeled, and selected relief- and holding-valve drawings carry pressure-setting data.

Bucket-cylinder YX01V00005 and arm-cylinder YY01V00003 tables distinguish rod-side, piston-side and combined repair kits. Their item references identify which seals and related parts are grouped together.

Separate drawings cover standard plumbing, boom safety, boom-and-arm safety and multi-control arrangements. Control-valve pages also distinguish breaker/nibbler, offset-boom and offset-telescopic configurations.

Tracks and Attachment Variants

Standard and LC roller arrangements have separate quantity listings. The long-crawler shoe assembly uses 46 shoes per track; additional shoe and slewing-ring entries carry their own applicability notes.

Attachment drawings cover the standard 4.6 m boom and long 2.95 m arm. Pins, bushings, dust seals and shim options are identified alongside the associated hydraulic lines and bucket installation hardware.

Harness Connections and Cab Parts

The Harness Assy drawing, figure 266-49, shows connector faces, wire codes and connections for the controller, switches, instrument cluster and pressure sensors. These are harness-layout and connector references, rather than a complete electrical circuit schematic.

The generator breakdown lists its voltage regulator, rectifier, rotor and stator.

Cab coverage extends to doors, windows, seat components and air conditioning. The latter includes the compressor, receiver-drier, evaporator, blower motor and controls.

Parts-List Gaps and Repair Scope

The exploded and sectional views show component relationships; they do not supply a teardown or reassembly sequence. This catalog does not provide step-by-step overhaul, troubleshooting or calibration procedures.

Component-list limits: 41 parts-list pages contain table headings without item entries. These include pages for pumps, swing and propelling motors, the regulator and swivel joints; corresponding illustrations are present, but those pages do not provide complete component-number lists.

The metric/inch hardware-conversion chart excludes tapped holes and mixed-thread nut-and-bolt pairs, where mismatches can damage fasteners or threaded mounting points.

Ensure you always consult a certified technician before performing service or making adjustments to heavy equipment.
