Hitachi machinery is known for its high performance and durability, commonly used in construction, mining, and excavation projects. However, there are times when operators or technicians may need to convert or retrofit certain components in their Hitachi equipment to enhance its performance, comply with regulations, or adapt it for specific tasks.
This article explores the process of Hitachi equipment conversion, providing practical instructions, tips, and potential pitfalls. By understanding the conversion process, owners can improve the versatility of their machinery and extend its operational lifespan.
Why Perform a Conversion on Hitachi Equipment?
Conversions are necessary for various reasons, including:
Several key conversion types are common in the Hitachi equipment industry, and understanding how to perform these changes is essential for operators and technicians.
1. Engine Conversion
One of the most common conversions for older Hitachi equipment is replacing the engine. A modern engine can offer greater fuel efficiency, improved power output, and better emissions control.
Another crucial conversion is upgrading the hydraulic system. With newer hydraulic technology, operators can achieve smoother and more efficient operations, especially in tasks that require precision, like digging or lifting.
As environmental regulations become more stringent, many older machines need to be converted to comply with new emissions standards. This often includes retrofitting engines with more advanced emission control systems.
Hitachi equipment is often used with specialized attachments. Conversions can be done to allow the machine to use attachments that were not originally designed for it, such as upgraded buckets, grapples, or specialized drilling tools.
Before embarking on any conversion project, there are several important factors to consider:
1. Compatibility
One of the primary considerations is whether the new components will fit and function correctly with the existing machine. Ensure that the components you plan to install are designed to work with the model you own.
Conversions can be costly, particularly if new components are required or if the process involves substantial modification to the equipment. It's crucial to assess whether the cost of conversion is worth the benefits, especially when compared to purchasing a new machine or renting specialized equipment.
3. Downtime and Operational Disruption
Conversions may require significant downtime, during which the equipment will be out of operation. Consider scheduling the conversion during a slow period or plan for the duration of the downtime in advance.
4. Professional Help vs. DIY
While some conversions can be performed in-house by experienced technicians, others may require professional help, especially when it comes to complex systems like hydraulic or electrical modifications. Depending on the complexity of the conversion, it may be beneficial to consult with Hitachi-certified service professionals.
Tools and Equipment Required for Conversions
While the specific tools required will vary depending on the type of conversion, most will involve basic mechanical tools as well as specialized equipment such as:
Converting heavy machinery involves high risks, especially when working with mechanical, hydraulic, and electrical systems. Here are some safety measures to consider:

Why Perform a Conversion on Hitachi Equipment?
Conversions are necessary for various reasons, including:
- Upgrading Performance: As technology evolves, certain components may need to be upgraded to match modern standards. This could include upgrading engines, hydraulics, or control systems for improved efficiency.
- Regulatory Compliance: Some older machines may need to be converted to meet new environmental regulations, especially concerning emissions and safety standards.
- Adapting for Specific Tasks: Sometimes, certain jobs may require specialized attachments or systems that the original machine was not designed for. Conversions can make machines more versatile and suited for various functions.
- Parts Availability: Over time, parts for older Hitachi models may become scarce or expensive. Converting the equipment to accept more readily available parts can be a cost-effective solution.
Several key conversion types are common in the Hitachi equipment industry, and understanding how to perform these changes is essential for operators and technicians.
1. Engine Conversion
One of the most common conversions for older Hitachi equipment is replacing the engine. A modern engine can offer greater fuel efficiency, improved power output, and better emissions control.
- Steps:
- Assess compatibility with the current engine compartment, including space for the new engine.
- Ensure the engine mounts and transmission systems are compatible with the new engine.
- Retrofit the cooling system and fuel delivery systems to match the specifications of the new engine.
- Assess compatibility with the current engine compartment, including space for the new engine.
- Benefits: This conversion improves fuel economy, reduces maintenance costs, and enhances power output. It can also bring the machine up to the latest emissions standards, especially in countries with strict environmental regulations.
Another crucial conversion is upgrading the hydraulic system. With newer hydraulic technology, operators can achieve smoother and more efficient operations, especially in tasks that require precision, like digging or lifting.
- Steps:
- Replace the hydraulic pumps and motors with more efficient models.
- Adjust the control valves and system pressures for the upgraded components.
- Update hydraulic hoses and fittings to handle the increased flow or pressure.
- Replace the hydraulic pumps and motors with more efficient models.
- Benefits: A modern hydraulic system will allow for faster response times and more precise control, improving overall machine efficiency and longevity.
As environmental regulations become more stringent, many older machines need to be converted to comply with new emissions standards. This often includes retrofitting engines with more advanced emission control systems.
- Steps:
- Install new exhaust filters and after-treatment systems like diesel particulate filters (DPF) or selective catalytic reduction (SCR) systems.
- Upgrade the fuel system to support new emission-reduction technologies.
- Test the system to ensure compliance with regulatory standards.
- Install new exhaust filters and after-treatment systems like diesel particulate filters (DPF) or selective catalytic reduction (SCR) systems.
- Benefits: Compliance with emissions regulations avoids costly fines and allows continued operation in regulated areas. It also helps reduce the environmental impact of older machines.
Hitachi equipment is often used with specialized attachments. Conversions can be done to allow the machine to use attachments that were not originally designed for it, such as upgraded buckets, grapples, or specialized drilling tools.
- Steps:
- Check the hydraulic capacity of the machine to ensure it can handle the new attachment.
- Modify or replace mounting brackets to make the attachment compatible with the existing frame or boom.
- Adjust the power take-off or hydraulic connections to accommodate the new attachment.
- Check the hydraulic capacity of the machine to ensure it can handle the new attachment.
- Benefits: This conversion adds flexibility, allowing the equipment to be used in a wider range of tasks. Whether it's digging, demolition, or material handling, the machine becomes more versatile.
Before embarking on any conversion project, there are several important factors to consider:
1. Compatibility
One of the primary considerations is whether the new components will fit and function correctly with the existing machine. Ensure that the components you plan to install are designed to work with the model you own.
- Example: When upgrading the engine, check the physical dimensions, mounting points, and power ratings to ensure compatibility.
Conversions can be costly, particularly if new components are required or if the process involves substantial modification to the equipment. It's crucial to assess whether the cost of conversion is worth the benefits, especially when compared to purchasing a new machine or renting specialized equipment.
