The Hitachi EX200-2 excavator is a reliable machine commonly used in construction and earthmoving operations. However, like any piece of heavy equipment, it may face mechanical issues that require attention. One such issue reported by operators is the malfunctioning of hydraulic systems, which often leads to concerns about hydraulic fluid flow and pressure, potentially affecting performance. A popular solution for some operators facing this problem is the installation of a hydraulic bypass kit.
In this article, we’ll discuss the common hydraulic problems encountered in the Hitachi EX200-2, explore the benefits of installing a bypass kit, and provide some real-world examples of how this upgrade can restore functionality and improve overall efficiency.
Common Hydraulic Issues in the Hitachi EX200-2
The EX200-2, like other heavy machinery, relies heavily on its hydraulic system to operate smoothly. Hydraulic issues can manifest in several ways, such as erratic movement, slow or unresponsive controls, or even total hydraulic failure. Here are some common hydraulic problems faced by EX200-2 owners:
A hydraulic bypass kit serves as a solution for maintaining or restoring hydraulic performance, particularly when dealing with pressure loss or fluid flow issues. The kit essentially redirects the flow of hydraulic fluid to bypass certain components of the hydraulic system that may be malfunctioning or clogged. This bypasses potentially damaged filters or valves and ensures the system continues to function until the issue can be properly addressed.
Benefits of Installing a Bypass Kit
While the installation process may vary slightly depending on the specific bypass kit you choose, here’s a general overview of the steps involved:
A construction company operating several Hitachi EX200-2 machines found that one of their units was experiencing hydraulic pressure loss. After inspecting the system, they realized that the hydraulic filter was clogged with dirt, leading to a decrease in fluid flow. Instead of shutting down the machine for a full hydraulic overhaul, they opted to install a hydraulic bypass kit.
The bypass kit effectively rerouted the fluid around the clogged filter, allowing the machine to continue operating at full capacity. The company was able to maintain productivity for several days while they scheduled a more extensive maintenance session to replace the filter and flush the hydraulic system.
This scenario highlights the importance of having a backup solution like a bypass kit in place. It’s a cost-effective and time-saving measure that can extend the operational life of your equipment.
Conclusion: When to Consider a Bypass Kit for the EX200-2
Hydraulic issues in the Hitachi EX200-2 excavator can be troublesome, but they don’t necessarily mean the machine has to be taken out of service immediately. Installing a hydraulic bypass kit can be a quick and efficient solution to keep the system running while you address the underlying issue. It’s a relatively simple upgrade that can save time and money, allowing operators to continue with their work without the frustration of extended downtime.
As with any repair or upgrade, regular maintenance and proper fluid care are essential for ensuring the longevity of your machine’s hydraulic system. Keeping the system clean, checking fluid levels, and replacing filters as needed will minimize the need for bypass kits and help your Hitachi EX200-2 perform reliably for years to come.

Common Hydraulic Issues in the Hitachi EX200-2
The EX200-2, like other heavy machinery, relies heavily on its hydraulic system to operate smoothly. Hydraulic issues can manifest in several ways, such as erratic movement, slow or unresponsive controls, or even total hydraulic failure. Here are some common hydraulic problems faced by EX200-2 owners:
- Hydraulic Pressure Loss
A decrease in hydraulic pressure is one of the most noticeable issues with the EX200-2. When the hydraulic system can’t maintain proper pressure, the machine’s movement becomes sluggish, and certain functions like boom lifts and digging become less efficient.
- Clogged or Worn Hydraulic Filters
Over time, hydraulic filters can become clogged with dirt and debris, reducing fluid flow. This can lead to pump cavitation, overheating, and an overall decline in performance.
- Hydraulic Fluid Leaks
Leaks are a common issue in older machines. A loss of hydraulic fluid due to worn hoses, seals, or other components can cause a drop in system pressure, making it impossible for the excavator to perform optimally.
- Contaminated Hydraulic Fluid
Contamination from water, dirt, or other impurities in the hydraulic fluid can cause serious damage to the pump, valves, and actuators. Contaminated fluid can lead to premature wear and tear, necessitating expensive repairs or even complete system overhauls.
A hydraulic bypass kit serves as a solution for maintaining or restoring hydraulic performance, particularly when dealing with pressure loss or fluid flow issues. The kit essentially redirects the flow of hydraulic fluid to bypass certain components of the hydraulic system that may be malfunctioning or clogged. This bypasses potentially damaged filters or valves and ensures the system continues to function until the issue can be properly addressed.
Benefits of Installing a Bypass Kit
- Cost-Effective Solution
Installing a bypass kit is a relatively affordable alternative to replacing major hydraulic components. This temporary fix can give operators more time to troubleshoot and solve the underlying issue without the immediate need for costly repairs.
- Increased System Efficiency
By redirecting the fluid flow, a bypass kit can help maintain hydraulic system performance, allowing the excavator to continue working while repairs are scheduled. This can reduce downtime and keep the machine operational during critical periods.
- Prevent Further Damage
In cases where contaminated fluid or clogged filters are causing issues, bypassing these components can help prevent additional strain on the hydraulic pump and valves, extending the life of the machine’s system.
- Minimizing System Failures
The kit can also help in the event of a total hydraulic failure, keeping essential functions like movement and lifting operational even if the main system is experiencing problems. This can be critical for operators who need the excavator to continue performing basic tasks until more extensive repairs can be made.
While the installation process may vary slightly depending on the specific bypass kit you choose, here’s a general overview of the steps involved:
- Identify the Problem Area
Before installing a bypass kit, it’s important to diagnose the hydraulic issue. Common indicators like sluggish movements or fluid loss will point to the area of concern (i.e., the hydraulic filter, valve, or pump).
- Locate the Bypass Kit Components
The bypass kit typically comes with hoses, valves, and fittings designed to reroute hydraulic fluid. It’s essential to have the correct kit for your machine model to ensure compatibility.
- Shut Down and Drain the Hydraulic System
Always make sure the machine is powered off, and the hydraulic system is depressurized before starting the installation. Drain the hydraulic fluid to prevent spills and ensure a safe working environment.
- Install the Bypass Kit
Install the bypass components as per the manufacturer’s instructions, ensuring that the hoses and fittings are securely attached to the appropriate parts of the hydraulic system. The bypass should reroute fluid away from the components that are causing the issue, maintaining flow and pressure.
- Refill Hydraulic Fluid
Once the bypass kit is installed, refill the hydraulic system with clean, high-quality hydraulic fluid to ensure smooth operation.
- Test the System
After installation, test the hydraulic system to ensure that fluid is flowing properly and that the bypass is functioning as intended. Check for any leaks or irregularities in system pressure.
