OEM Repair Hydraulic Piston Pump Parts HPV 95 For Komatsu PC200-7 | Tonkee®

Before initiating the repair process, conduct a thorough diagnostic assessment to identify the specific issues affecting the hydraulic piston pump.

This may involve inspecting the pump for leaks, assessing the condition of seals, and examining the overall functionality.

Disassembly:
Begin the repair process by carefully disassembling the hydraulic piston pump. This involves removing the pump from the excavator and taking it apart. Document the disassembly process meticulously, noting the placement and condition of each part. This information will be crucial during the reassembly stage.

Inspection of Parts:
Examine each component of the HPV 95 pump for wear, damage, or signs of fatigue. Pay special attention to critical parts such as the pistons, cylinder block, swashplate, and valve plate. If any part is found to be compromised, it should be replaced with genuine Komatsu parts to ensure compatibility and performance.

Cleaning and Degreasing:
Thoroughly clean and degrease all components to remove contaminants such as dirt, debris, and old hydraulic fluid. Utilize suitable cleaning agents to ensure that every part is free from foreign particles that could compromise the pump's functionality.

Replacement of Seals and Gaskets:
Inspect all seals and gaskets for signs of wear or damage.

Replace any compromised seals to prevent hydraulic fluid leaks, which can lead to a loss of pump efficiency. It is crucial to use high-quality replacement seals and gaskets that meet Komatsu's specifications.

Reassembly:
Carefully reassemble the hydraulic piston pump, referring to the documentation created during the disassembly phase. Follow the manufacturer's guidelines and torque specifications for each component to ensure proper fit and alignment. Exercise caution to avoid introducing contaminants during the reassembly process.

Testing and Calibration:
After reassembly, test the HPV 95 pump to ensure it operates smoothly and efficiently. Monitor for any unusual noises, vibrations, or fluid leaks. If necessary, calibrate the pump according to the Komatsu PC200-7 specifications to ensure optimal performance.
