The Caterpillar 955L, introduced in the early 1980s, is a powerful and versatile track loader that has earned its place in heavy-duty construction and earthmoving operations. However, like any piece of heavy machinery, the 955L can face issues that require attention. One common problem for operators is undercarriage leaks, particularly on the right side of the machine. This article will explore the reasons behind these leaks, how to diagnose them, and the steps needed to resolve the issue effectively.
Understanding the CAT 955L Track Loader
The CAT 955L is part of the renowned Caterpillar series of track loaders, a category of equipment designed to handle a variety of tasks, from lifting and digging to moving materials. Built for rugged durability, the 955L features a robust undercarriage that consists of tracks, rollers, sprockets, and idlers. These components are crucial for the machine’s mobility and stability on uneven terrain.
The undercarriage of a track loader like the CAT 955L is exposed to extreme stress due to constant contact with the ground, dirt, rocks, and other debris. Over time, these parts can wear out, leading to leaks in the hydraulic system, particularly in areas like the track drives or the hydraulic lines that power the undercarriage.
Identifying the Source of the Leak
Undercarriage leaks on the CAT 955L are often associated with the hydraulic system, which controls the movement of the tracks and other components. When you notice a fluid leak on the right side of the undercarriage, there are several potential culprits. Identifying the source of the leak is the first step in fixing the problem.
Proper diagnosis is key to fixing any hydraulic system leak. If you’ve identified a leak in the undercarriage of your CAT 955L, it’s important to follow these steps to determine the extent of the problem:
Preventing undercarriage leaks on the CAT 955L requires regular maintenance and monitoring of the machine’s hydraulic system. Here are some tips to help prevent leaks from occurring:
The CAT 955L is a durable and reliable track loader, but like any heavy equipment, it is prone to wear and tear over time. Undercarriage leaks, particularly on the right side, can be a significant issue for operators. By understanding the potential causes of these leaks—such as damaged hydraulic lines, worn final drive seals, or issues with track motors—operators can take the necessary steps to diagnose and resolve the problem.
Regular maintenance and careful inspection of the undercarriage components will not only extend the life of the CAT 955L but also help ensure its optimal performance in the field. By addressing leaks early and using high-quality replacement parts, operators can keep their machines running smoothly and efficiently for years to come.

When you notice a fluid leak on the right side of the undercarriage, there are several potential culprits. Identifying the source of the leak is the first step in fixing the problem.
- Hydraulic Lines and Fittings
One of the most common sources of leaks on track loaders is damaged hydraulic lines or fittings. These lines transport pressurized hydraulic fluid to the undercarriage components, such as the track motors and final drive assembly. Over time, hydraulic lines can become worn, cracked, or loose, causing leaks.- Solution: Inspect the hydraulic lines for signs of wear, cracks, or damage. Check all fittings and connections for tightness. If the lines are damaged, replace them with high-quality hydraulic hoses that meet the manufacturer's specifications.

- Final Drive Seals
The final drive assembly, which connects the hydraulic motors to the tracks, is another potential source of leaks. The seals around the final drive can wear out due to constant movement and pressure. When these seals fail, hydraulic fluid can escape, leading to a noticeable leak on the undercarriage.- Solution: Inspect the final drive seals for signs of wear. If necessary, replace the seals to prevent further fluid loss. Be sure to use OEM (Original Equipment Manufacturer) seals to ensure proper fit and function.

- Track Motors
The track motors are responsible for driving the tracks, and they are powered by hydraulic fluid. If the seals or gaskets on the track motors become damaged, fluid can leak out, leading to a loss of pressure and reduced performance.- Solution: If the leak is coming from the track motors, it may be necessary to remove and disassemble the motors to inspect the internal seals and gaskets. Replace any damaged parts and reassemble the track motors according to the manufacturer’s guidelines.

- Rollers and Idlers
The rollers and idlers support the tracks and allow them to move smoothly. These components are usually sealed to prevent contaminants from entering the system. However, over time, the seals can degrade, leading to leaks, especially if the machine has been operating in harsh conditions.- Solution: Inspect the rollers and idlers for any visible leaks or signs of damage. If the seals are compromised, replace them to restore the integrity of the undercarriage.

Proper diagnosis is key to fixing any hydraulic system leak. If you’ve identified a leak in the undercarriage of your CAT 955L, it’s important to follow these steps to determine the extent of the problem:
- Pressure Test the System
A pressure test can help you determine if the hydraulic system is operating at the correct pressure. A drop in pressure can indicate a leak in the system, and this can help pinpoint whether the leak is coming from the final drive, track motors, or hydraulic lines.
- Visual Inspection
A thorough visual inspection is essential for identifying the exact location of the leak. Check the hydraulic hoses, connections, and seals for visible signs of fluid seepage. Pay close attention to areas around the final drive and track motors, as these are common leak points.
- Check Fluid Levels
Low hydraulic fluid levels can be a sign of a significant leak. Before operating the machine further, check the hydraulic fluid levels and top up if necessary. Continued operation with low fluid levels can lead to severe damage to the hydraulic system.
- Clean the Area
Clean the undercarriage area where the leak is suspected. Dirt and debris can make it difficult to locate the exact source of the leak. Once cleaned, run the machine briefly and observe for any new fluid buildup, which can help pinpoint the leak.
Preventing undercarriage leaks on the CAT 955L requires regular maintenance and monitoring of the machine’s hydraulic system. Here are some tips to help prevent leaks from occurring:
- Regular Inspection and Maintenance
Make a habit of regularly inspecting the hydraulic lines, seals, and components of the undercarriage. Look for any early signs of wear or damage before they develop into major issues.
- Use High-Quality Hydraulic Fluid
Always use the recommended hydraulic fluid for your CAT 955L. Using the wrong fluid can lead to premature seal wear and hydraulic system issues. Consult the operator’s manual for the correct fluid specifications.
- Monitor Operating Conditions
Operating the machine in extreme conditions, such as on rough terrain or in extremely cold or hot environments, can put additional strain on the hydraulic system. Try to avoid overloading the machine or operating it in conditions that may cause undue stress on the undercarriage components.
- Replace Worn Components Promptly
Don’t wait for components like seals, hoses, or the final drive to fail completely. Promptly replace worn parts to avoid more serious damage that could lead to expensive repairs.
