Hydraulic systems are the lifeblood of many construction and agricultural machines, powering everything from steering and lifting to material handling. However, when these systems malfunction, it can cause significant downtime and frustration. A common issue that equipment operators and technicians face is when a newly installed hydraulic pump causes problems like tracking issues. In this article, we’ll explore the challenges involved with installing a new pump and how to troubleshoot these common issues.
The Importance of Hydraulic Pumps in Heavy Equipment
Hydraulic pumps are critical components in machines such as skid steers, excavators, and track loaders. They convert mechanical energy into hydraulic energy, which powers a wide range of functions on the machine. When a pump fails or is improperly installed, it can lead to uneven power distribution, causing a variety of symptoms including erratic steering, tracking problems, or even complete system failure.
Installing a new pump should ideally restore functionality, but as many experienced operators will tell you, this isn't always the case. A tracking issue—where a machine pulls to one side, even when the steering is centered—can be a frustrating byproduct of a new pump installation.
New Hydraulic Pump, New Problems
One user described a situation where after installing a new hydraulic pump, their equipment began to exhibit tracking issues. Initially, everything seemed fine, but the machine began pulling to one side. The operator had to figure out the underlying cause quickly, as it was affecting the machine’s efficiency and performance.
This problem is more common than one might think. Tracking issues are typically related to a variety of causes, from minor pump calibration problems to more significant system imbalances. Hydraulic flow to one side of the tracks might be uneven, which can cause the machine to veer off course.
Potential Causes of Tracking Problems After Installing a New Pump
Several issues could cause a newly installed hydraulic pump to affect the tracking of the equipment. These include:
Once the tracking issue is diagnosed, there are a few steps that operators can take to restore proper functionality:
In one real-world example, a fleet operator installed a new hydraulic pump on a Bobcat 763. Shortly after the pump was installed, the machine began veering to the left, making it impossible to drive in a straight line. The operator initially assumed that the pump was defective, but after recalibrating the system and bleeding the air from the lines, the problem persisted. The operator then realized that the hydraulic fluid wasn’t up to the recommended level, which was causing pressure issues.
After topping off the fluid and rechecking all the connections, the machine finally tracked straight, and the operator was able to get back to work. This situation highlights how a seemingly simple issue like low hydraulic fluid could cause significant problems after a pump installation.
Maintaining Hydraulic Systems for Long-Term Success
Preventing issues like tracking problems requires proper maintenance and attention to detail. Regularly checking the hydraulic system for leaks, ensuring that the fluid is clean and at the correct levels, and performing scheduled calibration can help operators avoid headaches down the road.
For operators, technicians, and fleet managers, investing time in proper pump installation and maintenance can pay off in the form of longer equipment life and improved performance.
The Future of Hydraulic Systems in Heavy Equipment
As hydraulic systems evolve, more advanced technologies are emerging to improve efficiency and reduce issues like the ones discussed. With advancements in smart hydraulic technology, future machines will likely be equipped with self-monitoring systems that can automatically detect and correct issues like tracking problems. The integration of electronic controls and automatic calibration will also make troubleshooting easier and reduce the likelihood of problems after a pump installation.
Conclusion: Ensuring Smooth Operation After Installing a New Pump
In conclusion, while installing a new hydraulic pump should enhance a machine’s performance, it can sometimes lead to complications like tracking issues. By paying attention to the causes—such as pump calibration, air in the system, fluid levels, and component integrity—operators can quickly identify and resolve these problems. With proper maintenance and troubleshooting, hydraulic systems can continue to perform at their best, helping operators stay efficient and effective on the job.

Potential Causes of Tracking Problems After Installing a New Pump
Several issues could cause a newly installed hydraulic pump to affect the tracking of the equipment. These include:
- Pump Calibration: After installing a new pump, the system may need proper calibration. This includes setting the correct pressure and flow rates to ensure that both sides of the system receive an equal amount of hydraulic power. If one side receives more flow than the other, the machine may pull to that side.
- Air in the System: If air enters the hydraulic lines during pump installation, it can cause erratic operation. Air pockets can prevent the fluid from flowing smoothly, leading to inconsistent steering or tracking behavior. It’s essential to bleed the air from the system after pump installation to avoid these issues.
- Improper Pump Installation: Incorrect installation of the hydraulic pump—whether it’s misalignment, improper torque, or unbalanced connections—can affect the pump’s performance. The pump needs to be properly mounted and aligned with the rest of the hydraulic system to function correctly.
- Faulty Components: A defective or damaged component in the system—such as a control valve, hose, or filter—can also create tracking issues. It’s important to check all parts for wear and tear during the pump installation process.
- Incorrect Fluid Levels: Low or improperly balanced hydraulic fluid can lead to uneven performance, resulting in tracking problems. Ensure the hydraulic fluid is filled to the correct level and is of the proper type to suit the system’s specifications.
Once the tracking issue is diagnosed, there are a few steps that operators can take to restore proper functionality:
- Re-calibration: The first step is to check the hydraulic system’s calibration. This can involve adjusting the flow control valves and ensuring both sides of the hydraulic motor are receiving equal amounts of fluid.
- Bleeding the System: As mentioned, air in the hydraulic lines is a common cause of uneven performance. Operators should use the machine’s manual to find the correct procedure for bleeding air from the hydraulic system.
- Check Fluid Levels: Ensure the hydraulic fluid is at the correct level and that it is the right type for the pump and the system. The wrong fluid can cause a variety of issues, including poor performance and damage to the pump.
- Inspect for Leaks or Obstructions: During the pump installation process, it’s essential to check for leaks or blockages in the lines. Leaks can cause pressure imbalances, while blockages can disrupt the smooth flow of hydraulic fluid.
