2006 Takeuchi TB153FR Compact Excavator Workshop Manual Set (P/N CJ2E000)

The Takeuchi sections provide machine-specific specifications and removal procedures, while the Yanmar publications cover internal engine and injection-equipment repair. The TNV engine book describes standard engine builds; use the Takeuchi specifications for the installed engine configuration.

Hydraulic, Engine, and Injection-System Repair

• Hydraulic units: Main-pump disassembly and reassembly, pilot-valve service, cylinder inspection, and swivel-joint repair.

• Travel and slew: Travel-motor overhaul, reduction-gear assembly, two-speed control diagnosis, slew-motor repair, and slew-bearing removal.

• Engine repair: Engine removal, cylinder-head and block work, valve adjustment, timing-gear service, and cooling- and lubrication-system inspection.

• Fuel injection: Injection-pump and governor overhaul, injection-timing adjustment, nozzle testing, and pump-specific service tools.

• Machine controls: Interference-prevention inspection and adjustment, proportional auxiliary-hydraulic control, and security-system troubleshooting.

• Electrical and air conditioning: Wiring diagrams, connector documentation, electrical inspections, leak testing, and manifold-gauge troubleshooting.

These manuals are intended for trained and qualified maintenance personnel. Hydraulic repairs and heavy-component removal require proper supports, lifting equipment, and safety precautions.

Hydraulic Diagnosis and Component Repair

Fault charts address weak travel, slow slewing, excessive cylinder drop, and auxiliary-control faults. Their component checks help distinguish pilot-circuit, control-valve, and actuator problems before disassembly.

The hydraulic circuit diagram and performance-test procedures accompany standard and allowable values for relief pressures, travel performance, and cylinder operation. Pump and cylinder sections add inspection criteria, seal-handling details, and assembly checks; swivel-joint troubleshooting distinguishes internal from external leakage.

Travel Motors, Slew Drive, and Machine Assemblies

The travel-motor section separates counterbalance and two-speed control operation from planetary reduction-gear service. Slew-drive documentation includes parking-brake operation, brake-valve construction views, and reduction-gear inspection.

Machine assembly drawings show engine mounts, hydraulic-pump couplings, and radiator/oil-cooler installation. Removal procedures also cover the upper frame, boom and attachment assemblies, dozer blade, rollers, idlers, and rubber or steel crawlers. Lubrication tables provide service intervals for the hydraulic system and undercarriage.

Internal Engine and Injection-Equipment Service

The TNV volume documents cylinder-head inspection and valve-seat correction. Gear-train, camshaft, crankshaft, and piston sections include measurement methods and wear limits; cooling and lubrication chapters cover water-pump and trochoid-pump service.

Injection-equipment scope: The pump application table pairs the 4TNV88 with the YPD-4MP2. The included injection-equipment book supplies the pump disassembly and assembly coverage referenced by the engine volume. Major internal-parts replacement requires adjustment with a special pump tester; listed tools include MP2 bottom-clearance gauge 158090-51800.

The engine book warns that disturbing the pump-flange bolts during removal makes injection-timing adjustment difficult.

Interference Prevention, Electrical Diagnosis, and Cab Systems

The interference-prevention chapter explains boom and offset switch operation and stop-position inspection. It warns that using switch settings to adjust the boom raise-stop position can allow the boom to strike the cab.

Electrical wiring diagrams, connector pin layouts, and wire-color connection tables support circuit tracing. Proportional-control documentation explains fault indications, while the security-system section covers immobilizer-key registration and diagnosis.

Air-conditioner coverage includes component construction, electrical checks, leak detection, and manifold-gauge patterns for identifying restrictions, charge problems, and expansion-valve faults.

Examples of Valve Clearance, Coolant Capacity, and Brake Data

For the 4TNV88, the engine service standards give a cold intake/exhaust valve clearance of 0.15–0.25 mm. The TB153FR machine table lists 8.4 L for the installed engine cooling system.

The MSG-27P-23E slew-motor specifications give parking-brake torque as 2,040 N·m or more. Separate brake-valve inspection tables address leakage, unstable pressure, and damaged sliding surfaces.

PDF Search, Drawing Detail, and Included Pages

Text search and drawing detail: Main text is searchable across the machine, engine, and injection-equipment sections. Some wiring and connector drawings lack searchable labels, and there are no embedded PDF bookmarks. Small pin numbers and wire-color codes in dense drawings require zooming.

One English-language, printable PDF contains all three publications in 686 pages. This total includes their covers, front matter, revision pages, eight blank separator pages, and the engine-section divider.
