2004 Takeuchi TL130 Crawler Loader Workshop Manual (P/N M9961-02E050)

This workshop manual covers the 2004 Takeuchi TL130 Crawler Loader, including Canopy and Cab configurations from serial number 21300004. It combines Takeuchi Book No. CT8E002, Rev. 1 with Yanmar TNE engine service information and TNV Publication No. M9961-02E050.

Text search and wiring detail: The PDF is partially searchable. The TNE engine section and many labels within the machine schematics cannot be searched. There are no embedded PDF bookmarks, and small wiring labels require zooming.

• Engine repair: Engine removal, cylinder-head and bottom-end inspection, intake/exhaust valve-clearance adjustment, fuel-injection timing, and separate service information for the TNE and TNV engines.

• HST and hydraulic units: Pump disassembly, neutral adjustment, displacement-limiter setting, gear-pump testing, and repair procedures for control, pilot, auxiliary, and self-level valves.

• Travel system: Travel-motor and reduction-gear repair, parking-brake inspection, crawler removal, and service limits for track rollers, idlers, and the track adjuster.

• Lift arms and bucket: Attachment removal, cylinder disassembly and seal replacement, internal-leak testing, air bleeding, and arm and bucket stopper adjustments.

• Electrical diagnosis: Serial-specific wiring diagrams, safety-bar interlock checks, second-speed circuit tests, starting-motor service, and alternator inspection and troubleshooting.

• Air conditioning: Compressor and condenser assembly drawings, supported by HVAC inspection procedures, manifold-gauge readings, leak diagnosis, and electrical checks.

Takeuchi wrote this manual for personnel engaged in maintenance work; its hydraulic testing and internal repair sections assume appropriate workshop equipment and service knowledge.

Engine Versions, Injection Timing, and Repair Limits

The engine changes from Yanmar 4TNE98-TBL at S/N 21300004–21301932 to 4TNV98-YTBL from S/N 21301933. The configuration pages distinguish engine mounts, radiators, fuel tanks and lines, and engine controls around this change. Separate drawings cover the hydraulic pilot controls.

The Yanmar sections cover cylinder-head work, valve guides and seats, pistons, connecting rods, crankshafts, and gear trains. Lubrication-system diagrams accompany trochoid-pump inspection; cooling-system coverage includes water-pump service, thermostat checks, and radiator testing.

Compression-pressure diagnosis includes test equipment references such as gauge set TOL-97190080 and adapters for different cylinder-head designs. Fuel-system coverage includes nozzle testing, injection-timing inspection and adjustment, and governor checks.

Injection-pump scope: The TNE section provides a limited Zexel pump/governor service extract and refers detailed adjustment to Zexel service. The TNV section covers YDP-MP pump operation, removal, installation, and the Cold Start Device (C.S.D.); internal MP-pump disassembly and assembly require a separate pump manual.

Turbocharger repair and wastegate adjustment are covered for the turbocharged variants identified in the Yanmar references, including the TNE chapter for the 4TNE106T.

HST Pump, Self-Level Valves, and Travel Drive

The PVM2828 HST pump section includes component inspection, servo-piston adjustment, neutral setting, and post-installation air purging. The manual warns that contamination beneath its valve plate can cause pump failure.

Separate self-level-valve sections distinguish machines below S/N 21301933 from those at S/N 21301933 onward. Travel reduction-gear drawings change at S/N 21300312, while attachment piping has a further change at S/N 21302047. These serial references help match the installed hardware to the appropriate drawings before parts are selected.

Hydraulic circuit diagrams and troubleshooting flowcharts cover weak operation, travel drift, overheating, loss of second speed, and excessive lift-arm or bucket drop. Their checks distinguish pilot-control, valve, pump, and cylinder faults.

Undercarriage, Attachments, and Service Data

Exploded views identify the travel motor, track rollers, idlers, and attachment assemblies. Standard and allowable wear values support decisions about component reuse or replacement. Machine dimensions, breakout force, travel speeds, engine displacement, compression ratios, and component dry masses are also tabulated.

Reference tables cover fluid capacities, coolant requirements, pressure-test specifications, and tightening torques for hydraulic hoses, bite-type pipe fittings, and ISO strength category 10.9 bolts. Pilot-valve and hydraulic-cylinder sections include dimensioned service-jig drawings.

Follow the manual's complete safety procedures for raised lift arms, stored hydraulic pressure, and heavy component removal.

Wiring Diagrams and Air-Conditioner Diagnosis

The electrical wiring diagrams separate the two engine builds and show optional high-flow, cab, and air-conditioning circuits where applicable. Harness layouts provide additional serial breaks for component identification.

The air-conditioner material combines machine assembly drawings with general heavy-equipment HVAC guidance. Manifold-gauge charts address low refrigerant, moisture, restrictions, compressor faults, and thermostatic-switch problems.

Combined Loader and Engine PDF

This is one printable English-language 712-page PDF: 311 pages of Takeuchi material, including the eight-page opening section; 180 pages of Yanmar TNE service information; and 221 pages of Yanmar TNV service information. The engine references, covers, revision information, and blank pages are already included in that total.
