Application: Primarily used in excavators such as PC400 – 8 and PC450 – 8 models.
Manufacturer Origin: Japan (associated with excavator manufacturers from Japan)
2. Performance Specifications
Power Output
Rated Power: The rated power of this engine usually ranges from around 257 – 307 kW (345 – 412 horsepower). This power output is designed to provide sufficient force for the heavy – duty operations of the excavators.
Maximum Power: In situations requiring extra power, such as heavy – duty digging through tough materials, the engine can potentially provide a slightly higher output for short – term operations.
Speed
Rated RPM: The engine's rated speed is typically around 1800 – 2000 revolutions per minute (RPM). This speed range is optimized to deliver the right amount of torque for the excavator's hydraulic systems and other operational requirements.
3. Mechanical Specifications
Configuration
Cylinder Arrangement: In – line 6 – cylinder configuration. This layout provides good balance and smooth operation, reducing vibrations and noise during the engine's operation.
Bore and Stroke: The bore diameter is usually around 125 mm and the stroke length around 150 mm. These dimensions play a crucial role in determining the engine's displacement and combustion characteristics.
Spostamento: The displacement of the SAA6D125E – 5 engine is approximately 11.04 liters. Calculated using the formula V = π/4 × (bore)²× stroke × number of cylinders.
Peso
Dry Weight: The dry weight of the engine (without coolant, fuel, and oil) is approximately 900 – 1000 kg. The actual weight may vary depending on additional components or accessories.
Wet Weight: With all fluids (coolant, fuel, and oil) filled to the recommended levels, the weight can increase to around 1000 – 1100 kg.
Dimensions
Length: Circa 1300 – 1400 mm.
Width: Around 900 – 1000 mm (including external components like manifolds).
Height: Roughly 1100 – 1200 mm. These dimensions are approximate and can vary based on the specific installation requirements and additional equipment attached.
