4. Setup and Installation
Installation of a hydraulic pump assembly requires specialized knowledge and tools. It is strongly recommended that this procedure be performed by a certified technician.
- Pre-Installation Check: Before installation, verify that the part number 708-2L-00400 matches the requirements for your Komatsu PC200-8 or PC220-8 Excavator. It is advisable to compare the nameplate of your old pump with the specifications of this replacement part.
- System Preparation: Ensure the excavator's hydraulic system is depressurized and drained of fluid before removing the old pump.
- Mounting: Carefully mount the new hydraulic pump assembly, ensuring all connections are secure and properly aligned.
- Fluid Replacement: Refill the hydraulic system with the manufacturer-recommended hydraulic fluid, ensuring it meets the correct specifications and cleanliness standards.
- Bleeding the System: Follow the excavator manufacturer's procedure for bleeding air from the hydraulic system after installation to prevent cavitation and damage.
- Initial Start-up: Perform a controlled initial start-up and check for leaks, unusual noises, or abnormal operation.
5. Operating Instructions
Once the hydraulic pump assembly is correctly installed and the system is fully operational, the excavator can be used according to its standard operating procedures. The new pump should integrate seamlessly with the existing hydraulic system.
- Monitor Performance: During initial operation, closely monitor hydraulic pressure, temperature, and overall system response.
- Fluid Levels: Regularly check hydraulic fluid levels and top up as necessary.
- Listen for Abnormalities: Pay attention to any unusual noises or vibrations from the pump or hydraulic system, which could indicate a problem.
6. Maintenance
Regular maintenance is crucial for the longevity and efficient operation of your hydraulic pump and the overall excavator hydraulic system.
- Hydraulic Fluid: Adhere to the excavator manufacturer's recommended schedule for hydraulic fluid changes. Use only specified fluid types.
- Filters: Replace hydraulic filters regularly as per the excavator's maintenance schedule to prevent contamination and protect the pump.
- Leak Checks: Periodically inspect all hydraulic lines, fittings, and the pump itself for any signs of leaks. Address leaks immediately.
- Mounting Bolts: Check the tightness of mounting bolts for the hydraulic pump and associated components.
- Visual Inspection: Conduct routine visual inspections for any signs of wear, damage, or corrosion on the pump and surrounding components.
7. Troubleshooting
This section provides general guidance for common issues. For detailed troubleshooting, refer to your excavator's service manual or consult a qualified technician.
| Problem | Possible Cause | Action |
|---|---|---|
| Low Hydraulic Pressure | Low fluid level, clogged filter, internal pump wear, relief valve issue. | Check fluid level, replace filter, inspect pump for damage, check relief valve settings. |
| Excessive Noise from Pump | Air in system (cavitation), contaminated fluid, loose mounting, worn bearings. | Bleed air from system, change fluid/filters, tighten mounts, inspect for wear. |
| Overheating Hydraulic System | Low fluid level, clogged cooler, incorrect fluid viscosity, excessive load. | Check fluid level, clean cooler, verify fluid type, reduce load if possible. |
| Hydraulic Leaks | Loose fittings, damaged seals, cracked housing. | Tighten connections, replace damaged seals/hoses, inspect pump housing. |
