The Caterpillar 980G is a versatile wheel loader used in heavy construction, material handling, and mining operations. It is known for its powerful engine, durable design, and efficient hydraulics. However, to further enhance its functionality, many operators seek to add a third valve to the machine, enabling the use of additional hydraulic attachments or improving the versatility of the machine for specific tasks.
In this article, we’ll dive into the process of adding a third valve to a Caterpillar 980G, including the steps involved, necessary parts, and potential challenges. We will also discuss the benefits of upgrading the hydraulic system and the importance of proper maintenance.
1. Understanding the Function of the Third Valve
A third valve is an additional hydraulic valve that provides a secondary hydraulic function, often used to power attachments that require a separate hydraulic flow, such as grapples, snowplows, forks, and other tools. In the case of the Caterpillar 980G, the third valve allows operators to control multiple attachments without requiring a separate external hydraulic system.
The 980G typically comes with two standard hydraulic circuits:
2. Why Add a Third Valve?
Adding a third valve to the 980G can significantly increase the machine’s versatility and productivity. Here are some reasons why you might consider upgrading:
The process of adding a third valve to the Caterpillar 980G requires careful planning and proper parts. Here are the general steps involved:
1. Determine the Configuration
Before purchasing any parts or performing any installation, you must determine the configuration of the third valve assembly. There are different setups, including a single valve or a complete three-valve assembly, depending on the attachments and hydraulic flow requirements.
To add a third valve, you’ll need the following components:
3. Install the Third Valve Assembly
The installation of a third valve assembly typically involves the following steps:
Once the third valve is installed, it is important to check the hydraulic fluid levels and the system’s pressure. This will ensure that the hydraulic system can handle the additional load created by the new valve and attachments.
While the process of adding a third valve is straightforward for experienced technicians, it can present challenges, especially when modifying a machine’s hydraulic system. Some common issues include:
Adding a third valve to your Caterpillar 980G wheel loader is an excellent way to increase its versatility, allowing it to operate additional attachments with ease. By following the installation steps carefully, gathering the correct parts, and performing regular maintenance on the hydraulic system, you can significantly improve the productivity of your machine.
Upgrading your machine’s hydraulic system with a third valve enhances its functionality, making it more efficient on the job site. This is especially beneficial for operators working in environments that require specialized attachments or multitasking.
Whether you are a construction contractor, a material handler, or a mining operator, customizing your Caterpillar 980G with a third valve ensures that it meets the demands of various tasks, making it a more powerful and versatile tool for heavy-duty work.

1. Understanding the Function of the Third Valve
A third valve is an additional hydraulic valve that provides a secondary hydraulic function, often used to power attachments that require a separate hydraulic flow, such as grapples, snowplows, forks, and other tools. In the case of the Caterpillar 980G, the third valve allows operators to control multiple attachments without requiring a separate external hydraulic system.
The 980G typically comes with two standard hydraulic circuits:
- Main Lift Circuit: Controls the bucket or other lifting attachments.
- Tilt Circuit: Controls the tilting motion of the bucket or attachment.
2. Why Add a Third Valve?
Adding a third valve to the 980G can significantly increase the machine’s versatility and productivity. Here are some reasons why you might consider upgrading:
- Increased Attachment Versatility: Many attachments, such as clamshell buckets, hydraulic thumbs, and fork attachments, require additional hydraulic flow to function properly. A third valve provides the necessary hydraulic control for these attachments.
- Improved Efficiency: With a third valve, operators can control multiple functions without the need to swap attachments or manually adjust hydraulic lines, making operations faster and more efficient.
- Customization: Adding a third valve enables customized solutions for specific job requirements, whether it’s for lifting, handling materials, or specialized operations.
The process of adding a third valve to the Caterpillar 980G requires careful planning and proper parts. Here are the general steps involved:
1. Determine the Configuration
Before purchasing any parts or performing any installation, you must determine the configuration of the third valve assembly. There are different setups, including a single valve or a complete three-valve assembly, depending on the attachments and hydraulic flow requirements.
- Single Valve: This option adds just one hydraulic circuit for controlling a single attachment. It’s a simple upgrade for machines that need to control one additional hydraulic function.
- Three-Valve Assembly: This is a more comprehensive upgrade that provides three separate hydraulic functions, each with its own valve, suitable for machines requiring more complex operations.
To add a third valve, you’ll need the following components:
- Third Valve Assembly: This includes the valve body, spool valves, and the necessary hydraulic connections.
- Hydraulic Hoses: Appropriate hoses to connect the valve to the existing hydraulic system.
- Fittings and Connectors: These are required for connecting the hoses to the machine and the valve assembly.
- Control Lever: A new lever or joystick for controlling the third hydraulic function.
3. Install the Third Valve Assembly
The installation of a third valve assembly typically involves the following steps:
- Disconnect the Battery: Always disconnect the battery before performing any hydraulic or electrical work.
- Locate the Hydraulic Ports: Identify the hydraulic ports on the machine where the third valve will be connected. These are usually located near the rear of the loader.
- Mount the Valve: The valve assembly must be securely mounted to a location on the loader that allows for easy access and connection to the hydraulic lines. Often, this involves using pre-existing mounting points on the frame or subframe.
- Connect Hydraulic Lines: Connect the hydraulic lines from the third valve to the main hydraulic system. This may require disconnecting existing lines or adding new connections to the machine.
- Install the Control Lever: If your upgrade involves a new control lever, install it in the operator's cab. The lever should be positioned for easy operation while maintaining ergonomics and safety.
- Test the System: After the installation is complete, carefully test the hydraulic system. Ensure that the valve operates correctly and that the hydraulic flow is sufficient to power the desired attachment.
Once the third valve is installed, it is important to check the hydraulic fluid levels and the system’s pressure. This will ensure that the hydraulic system can handle the additional load created by the new valve and attachments.
- Check Fluid Levels: Make sure that the hydraulic fluid reservoir is topped off to the correct level, as additional valves can cause the fluid to drop more quickly.
- Pressure Testing: Perform a pressure test to verify that the system is functioning correctly under load.
While the process of adding a third valve is straightforward for experienced technicians, it can present challenges, especially when modifying a machine’s hydraulic system. Some common issues include:
- Hydraulic Compatibility: The new valve assembly must be compatible with the existing hydraulic system. Incompatible valves can lead to reduced efficiency, leaks, or even system failure.
- Space Constraints: Finding an appropriate mounting location for the valve can be difficult, particularly on larger machines with limited space in the hydraulic compartment.
- System Overload: If the hydraulic system is not properly calibrated, adding a third valve could strain the system, causing overheating or excessive wear on components.
Adding a third valve to your Caterpillar 980G wheel loader is an excellent way to increase its versatility, allowing it to operate additional attachments with ease. By following the installation steps carefully, gathering the correct parts, and performing regular maintenance on the hydraulic system, you can significantly improve the productivity of your machine.
