Takeuchi TB15/120 Compact Excavator Parts Catalog (P/N 00543-01542)

• Official Takeuchi factory parts publication (internal reference B2-15/120) strictly providing component identification, not diagnostic or repair procedures
• Designed for technicians and owners servicing Takeuchi TB15 and TB120 compact excavators with serial numbers 00543 and higher
• Includes exploded-view diagrams detailing component hierarchy, hardware placement, and assembly for major machine systems
• Detailed cross-reference tables map exact part numbers, required quantities, and specific serial number fitment across both configurations

Component and System Index

Understanding the exact layout of your machinery saves hours in the shop. This documentation delivers a complete breakdown of the Takeuchi TB15 and TB120, starting from the ground up. You get a clear look at the lower chassis and undercarriage components. Exploded views highlight track rollers, front idlers, lower piping, and blade hydraulic cylinders. Seeing the individual hardware and seals for track spring mechanisms or travel devices eliminates guesswork during reassembly.

Moving to the upper machinery, the catalog maps out the operator station and rotating platform. It breaks down the turret, slewing devices, and critical control box elements like hour meters, water temperature gauges, and glow registers. Operator controls are fully detailed. You will find exact diagrams for travel levers, swing pedals, and both the right and left operation lever banks. The guide also covers the physical structure of the cabin and canopy, including door hinges, interior handles, wiper motor parts, and glass fitment. Before ordering replacement parts or starting a teardown, remember to observe all standard workshop safety practices and properly support heavy frame structures.

Engine, Hydraulic, and Electrical Specifications

Cooling systems and engine mounts require exact hardware verification. Specialized chapters document the radiator mounting, engine foot assemblies, and associated piping. The hydraulic section lists everything needed to identify main control valves, tanks, filters, and routing circuits across the machine. Electrical layouts are equally comprehensive, mapping out wiring harnesses, battery connections, lighting circuits for both cab types, and horn assemblies.

• The TB15/120 hydraulic tank specifies filter element part 15510-45180 for the cartridge assembly. Always relieve system pressure before opening hydraulic circuits to prevent serious injury.
• Main hydraulic valve control units are sorted by serial range starting from 00543.
• Seat belt assemblies are broken down by exact serial applicability: ranges 00543–06361 or 06362 and after.
