Takeuchi TL140 Fuel Tank and System Overview

[MikePhua]

The Takeuchi TL140 is a rubber track loader designed for robust performance in construction, landscaping, and agricultural applications. An essential component supporting its engine and operational endurance is the fuel tank, which balances capacity, safety, and ease of maintenance.
Fuel Tank Capacity and Specifications

• The standard fuel tank capacity of the Takeuchi TL140 is approximately 23.8 gallons (90.1 liters).
  
• This volume supports extended operation without frequent refueling, facilitating productive jobsite workflows.
  
• The fuel tank is designed for compatibility with diesel fuel, the engine’s primary fuel type, specifically an Isuzu 4JG1T 4-cylinder turbocharged diesel engine.
  

Fuel System Components

• The fuel tank assembly includes fuel lines, filters, and a fuel pump critical for delivering clean fuel at consistent pressures to the engine's injection system.
  
• Advanced filtration helps remove contaminants that can cause engine wear or poor performance.
  
• The placement of the tank on the machine balances weight distribution and protects it from damage during operations.
  

Engine and Cooling Capacities Complementing the Fuel System

• The Isuzu engine puts out approximately 60.3 kW (about 81 hp) at 2,500 rpm, with peak torque near 262 Nm at 1,800 rpm.
  
• The cooling system uses about 15 liters (4 gallons) of fluid to maintain optimal engine temperature and prevent overheating during heavy use.
  
• Engine oil capacity is roughly 9.6 liters (2.5 gallons), supporting lubrication and longevity.
  
• The hydraulic system holds about 13.7 gallons (52 liters) of fluid, critical for loader and track functions.
  

Electrical System and Other Specs

• The machine uses a 12-volt electrical system with an 80-amp alternator.
  
• Tires measure approximately 450 mm wide rubber tracks, providing stability and flotation over soft ground.
  
• The loader achieves a tipping load of around 2,700 kg, aligning with its fuel and hydraulic system capacities for efficient power application.
  

Maintenance and Safety Notes

• Regular inspection of the fuel tank, including vent lines and caps, prevents contamination and vapor buildup.
  
• Using diesel fuel with proper lubricity extends the life of injection components.
  
• Careful routing of fuel lines away from heat sources and moving parts prevents leaks and potential fire hazards.
  
• Properly sealed fuel cap designs preserve fuel quality and reduce evaporation losses.
  

Technical Terms Explained

• Tipping Load: The maximum safe weight the loader can lift without tipping forward.
  
• Turbocharged Diesel Engine: An engine with forced induction improving power and efficiency.
  
• Hydraulic System Fluid: Specialized oil used to operate hydraulic cylinders and motors.
  
• Alternator: Electrical device that charges the battery and powers electrical systems.
  
• Flotation: The ability of a track or tire to distribute machine weight to minimize sinking into soft soil.
  

Practical Insight
Operators have observed the Takeuchi TL140’s fuel tank size allows a full day's work under heavy loads with a single fill. Its placement reduces damage risk on rough jobsites. Proper fuel system maintenance has proven critical for the engine’s responsiveness in cold and hot climates alike.
Summary
The Takeuchi TL140 loader’s fuel tank capacity and integration are designed to support robust engine performance and long operating hours. Combined with efficient diesel engine technology, hydraulic fluid management, and durable construction, the TL140 promises reliable fuel supply and optimized machine productivity in demanding environments. Understanding these system specifications and maintenance priorities contributes to effective operation and extended equipment lifespan.
