The EX200-3 excavator, manufactured by Hitachi, is a reliable and powerful machine, known for its efficiency and durability. However, like any complex machinery, it may require updates or modifications to maintain optimal performance. One such modification is the hydraulic pump conversion kit, which can significantly enhance the hydraulic system's functionality and extend the machine's lifespan. This article provides a comprehensive guide on the hydraulic pump conversion kit for the EX200-3, including its benefits, installation process, and troubleshooting tips.
Why Opt for a Hydraulic Pump Conversion Kit?
The hydraulic pump is a critical component in any excavator, powering functions such as boom lift, arm movement, and swing functions. Over time, the performance of the hydraulic pump may deteriorate due to wear and tear, resulting in reduced efficiency, slow operation, or even system failures. In some cases, the existing hydraulic pump may not be able to handle the machine's increasing demands, especially if you are using the excavator for heavy-duty tasks.
A hydraulic pump conversion kit is designed to replace the existing pump with a more efficient and durable model. The new pump improves hydraulic performance, ensures smoother operation, and provides better fuel efficiency. It is also a solution when the original pump is no longer available or if it's cost-prohibitive to repair the old pump.
Benefits of the Hydraulic Pump Conversion Kit
Installing the hydraulic pump conversion kit on the EX200-3 is a moderately complex process that requires a basic understanding of hydraulic systems and machine maintenance. Below are the general steps for installation:
Even after installing the conversion kit, there may be occasional issues with the hydraulic system. Here are a few troubleshooting tips to help diagnose and resolve common problems:
The hydraulic pump conversion kit for the Hitachi EX200-3 offers a reliable and efficient solution to improve the performance of your excavator’s hydraulic system. By upgrading to a more efficient pump, you can ensure that the machine operates at optimal levels, reduces fuel consumption, and extends the lifespan of the hydraulic system. Proper installation and routine maintenance will help keep your excavator running smoothly, ensuring maximum productivity and minimal downtime. Always consult the machine’s manual and, if necessary, seek professional assistance to ensure proper installation and system optimization.

Benefits of the Hydraulic Pump Conversion Kit
- Improved Hydraulic Performance
The new pump in the conversion kit typically offers higher flow rates and better pressure capabilities. This improvement results in faster response times and more efficient use of hydraulic power, ensuring that the excavator can handle heavier workloads more effectively.
- Enhanced Fuel Efficiency
By upgrading to a more efficient pump, the machine can operate with less fuel consumption, helping reduce operational costs over time.
- Increased Durability
The hydraulic pump conversion kit often includes a more robust design with better materials, leading to a longer lifespan and fewer maintenance needs.
- Compatibility with Newer Technology
Upgrading to a newer hydraulic pump ensures that the excavator's hydraulic system is compatible with modern components and technologies, further improving overall performance.
- Cost-Effective Solution
Rather than opting for expensive repairs to the original hydraulic pump, a conversion kit offers a more affordable alternative that delivers enhanced functionality.
Installing the hydraulic pump conversion kit on the EX200-3 is a moderately complex process that requires a basic understanding of hydraulic systems and machine maintenance. Below are the general steps for installation:
- Prepare the Excavator
- Begin by parking the excavator on level ground and ensuring it is powered off. Disconnect the battery to prevent accidental electrical short circuits during the installation process.
- Begin by parking the excavator on level ground and ensuring it is powered off. Disconnect the battery to prevent accidental electrical short circuits during the installation process.
- Remove the Old Hydraulic Pump
- Locate the hydraulic pump and disconnect the hydraulic lines and electrical connectors from the old pump.
- Use appropriate tools to unbolt and remove the old pump from its mounting location. Be cautious when handling the pump to avoid damage to other components.
- Locate the hydraulic pump and disconnect the hydraulic lines and electrical connectors from the old pump.
- Install the New Pump
- Place the new hydraulic pump into the mounting location, ensuring it aligns correctly with the system’s connections.
- Bolt the pump into place and reconnect the hydraulic lines and electrical connectors. Ensure that all connections are tight and secure to prevent leaks.
- Place the new hydraulic pump into the mounting location, ensuring it aligns correctly with the system’s connections.
- Fill the Hydraulic Reservoir
- Refill the hydraulic reservoir with the appropriate hydraulic fluid as specified in the machine’s manual. Check for any leaks around the pump and fittings.
- Refill the hydraulic reservoir with the appropriate hydraulic fluid as specified in the machine’s manual. Check for any leaks around the pump and fittings.
- Test the System
- Start the excavator and perform a series of tests to ensure the new pump is functioning correctly. Check the hydraulic functions (boom, arm, and swing) to verify that the system is operating smoothly and efficiently.
- Monitor the pressure and flow rates to confirm that the hydraulic pump is providing adequate power.
- Start the excavator and perform a series of tests to ensure the new pump is functioning correctly. Check the hydraulic functions (boom, arm, and swing) to verify that the system is operating smoothly and efficiently.
- Perform Final Checks
- After testing, perform a final inspection of the system, checking for leaks and verifying that the pump is working optimally.
- Recheck the hydraulic fluid levels and top them off if necessary.
- After testing, perform a final inspection of the system, checking for leaks and verifying that the pump is working optimally.
Even after installing the conversion kit, there may be occasional issues with the hydraulic system. Here are a few troubleshooting tips to help diagnose and resolve common problems:
- Slow Hydraulic Response
- If the hydraulic response is slower than expected, check the hydraulic fluid levels. Low fluid levels can cause sluggish performance.
- Inspect the hydraulic filter for blockages. A clogged filter can restrict fluid flow, causing slow movement.
- If the hydraulic response is slower than expected, check the hydraulic fluid levels. Low fluid levels can cause sluggish performance.
- Hydraulic Leaks
- Hydraulic leaks are a common issue after pump installation. Inspect all hydraulic lines, fittings, and the pump itself for leaks. Tighten any loose connections or replace damaged hoses.
- Ensure that the seals and O-rings are in good condition and correctly installed.
- Hydraulic leaks are a common issue after pump installation. Inspect all hydraulic lines, fittings, and the pump itself for leaks. Tighten any loose connections or replace damaged hoses.
- Excessive Noise
- If the system is making excessive noise, it could indicate air in the hydraulic lines or low fluid levels. Bleed the air from the system and top off the hydraulic fluid as needed.
