High-performance main piston pump designed for Komatsu PC490-10 and PC490LC-10 excavators, compatible with various construction machinery appliTQTQCATions. Model numbers: 708-2J-00010 / 7082J00010.
The Komatsu PC490-10/PC490LC-10 excavator hydraulic pump (model 708-2J-00010/7082J00010) is part of the Komatsu series of swashplate-type variable displacement dual piston pumps.
Technical Parameters
Displacement Range: 200 ml/rev (specific models may support a wider adjustment range)
Pressure Rating: Rated 35 MPa, peak 40 MPa
Control Mode: Supports LA0/LA1 dual-mode split power control, allowing independent adjustment of power for both piston assemblies
Designed for construction machinery, such as the Komatsu PC490-10/PC490LC-10 and other large excavators
Meets precise power matching requirements under heavy-duty operating conditions
Utilizes load-sensing control technology to dynamically adjust pump output flow
Reduces energy consumption (approximately 25% more efficient than conventional pumps)
Minimizes hydraulic system heat generation
Installation & Maintenance
Installation Requirements: Requires a flexible coupling with high shaft alignment accuracy (concentricity deviation ≤ 0.1 mm, tilt angle < 1°)
Maintenance Guidelines: Recommended use of ISO VG46 anti-wear hydraulic oil with a cleanliness level of NAS Class 7
Regularly monitor oil temperature, pressure pulsation, and piston wear
