The Caterpillar 299D is a powerful and versatile skid steer loader that excels in various construction, landscaping, and material handling applications. As with any heavy equipment, regular maintenance is key to ensuring optimal performance and longevity. One of the essential maintenance tasks for the 299D is replacing or installing track rollers—critical components that support the weight of the machine and ensure smooth movement of the tracks. If the track rollers are worn or damaged, they can cause uneven wear on the tracks, reduced stability, and even affect the overall efficiency of the machine. This guide will walk you through the process of installing track rollers on the CAT 299D skid steer, providing you with the essential steps, tips, and tools required.
Understanding the Role of Track Rollers
Before diving into the installation process, it's important to understand the role of track rollers in the operation of the CAT 299D. Track rollers are part of the undercarriage system and are responsible for supporting the weight of the machine while allowing the track to rotate smoothly over the ground. They help distribute the machine's weight evenly across the track, ensuring that the track remains in contact with the ground and operates efficiently. Worn or damaged rollers can cause excessive track wear, vibrations, and poor handling.
The CAT 299D features an undercarriage system with multiple track rollers located along the length of the track frame. Over time, these rollers can wear down, leading to the need for replacement. Installing new rollers not only restores the machine's handling but also helps to prolong the lifespan of the tracks and other undercarriage components.
Signs That Track Rollers Need to Be Replaced
Track rollers on the CAT 299D can wear out due to constant use and exposure to harsh working conditions. Some common signs that the rollers need replacement include:
Before you begin the track roller installation process, it’s important to gather the necessary tools and take proper safety precautions. Here’s what you’ll need to get started:
Tools and Equipment:
Follow these steps to replace the track rollers on your CAT 299D skid steer:
Step 1: Lift the Machine
To access the track rollers, you’ll need to lift the machine off the ground. Use a hydraulic jack or a lift to raise the machine until the tracks are no longer in contact with the ground. Make sure the machine is stable and secure before proceeding. Always follow the manufacturer's guidelines for lifting the machine.
Step 2: Remove the Old Track Rollers
With the machine lifted and stabilized, you can begin removing the old track rollers. Start by inspecting the area around the rollers and identifying the bolts that hold them in place. Using a socket wrench, remove the bolts securing the roller to the undercarriage frame.
Depending on the wear and tear, some bolts may be difficult to remove. In this case, apply a penetrating lubricant to loosen the bolts and make removal easier. Be sure to keep track of the bolts and any washers that come off with the rollers.
Step 3: Install the New Track Rollers
Once the old rollers have been removed, it’s time to install the new ones. Before installing, lubricate the new rollers and bearings with grease to ensure smooth movement and reduce wear. Align the new roller with the mounting points on the undercarriage and secure it with the bolts you previously removed.
Use a torque wrench to tighten the bolts to the manufacturer’s recommended specifications. It’s essential to ensure that the rollers are tightly secured to avoid any future issues with loose components.
Step 4: Adjust Track Tension
After installing the new rollers, check the track tension. Proper track tension is crucial for the optimal performance of the tracks and rollers. Use the appropriate tools to adjust the track tension if necessary. Ensure the tracks are evenly tight across the machine to prevent unnecessary wear.
Step 5: Test the Machine
Once the new track rollers are installed and the tracks are properly tensioned, lower the machine back to the ground. Start the engine and test the machine’s movement by operating it in various directions. Listen for any unusual noises and check the stability of the tracks. If everything runs smoothly, you’ve successfully installed the track rollers.
Tips for Maintaining Track Rollers
To maximize the lifespan of your track rollers and avoid frequent replacements, it’s important to maintain the undercarriage regularly. Here are some tips for maintaining your track rollers:
A construction company faced frequent downtime due to damaged track rollers on their CAT 299D. After replacing the rollers, they implemented a regular maintenance schedule, including monthly inspections and lubrication. Over the following months, they noticed a significant decrease in the frequency of repairs and a reduction in downtime, leading to increased productivity and lower overall maintenance costs.
Conclusion: The Importance of Proper Track Roller Installation
Installing track rollers on the CAT 299D is a relatively straightforward process that can significantly enhance the performance and lifespan of the machine. By following the correct steps, using the right tools, and regularly maintaining the undercarriage, you can ensure that your skid steer continues to operate at peak efficiency. Regular maintenance not only reduces downtime but also extends the life of the machine, helping you avoid costly repairs and replacements. Whether you're a seasoned operator or a newcomer to heavy equipment, understanding the importance of track roller maintenance is key to keeping your CAT 299D running smoothly.

Signs That Track Rollers Need to Be Replaced
Track rollers on the CAT 299D can wear out due to constant use and exposure to harsh working conditions. Some common signs that the rollers need replacement include:
- Excessive Noise or Vibration: If you hear unusual noises or feel increased vibrations when the machine is in motion, it could be a sign of worn or damaged rollers. These issues can indicate that the rollers are no longer providing proper support, leading to uneven track wear.
- Uneven Track Wear: If you notice that the tracks are wearing down unevenly, especially on one side, it may be due to failing rollers. Uneven wear can result in a decrease in machine performance and handling.
- Visible Damage to Rollers: Inspect the rollers for visible signs of wear, such as cracks, dents, or rust. Damaged rollers will affect the overall efficiency of the track system and can lead to further damage if not addressed promptly.
- Loss of Track Tension: Track rollers help maintain the proper tension in the tracks. If the rollers are worn or broken, it can cause the tracks to lose tension, resulting in poor machine stability and track slippage.
Before you begin the track roller installation process, it’s important to gather the necessary tools and take proper safety precautions. Here’s what you’ll need to get started:
Tools and Equipment:
- Jack or Lift: To raise the machine and provide access to the undercarriage.
- Socket Wrench Set: For removing bolts and securing the new rollers in place.
- Torque Wrench: To ensure bolts are tightened to the correct specification.
- Lubricant or Grease: To lubricate the rollers and bearings during installation.
- Replacement Track Rollers: Ensure you have the correct size and type of track rollers for the CAT 299D.
- Safety Gear: Always wear safety gloves, goggles, and steel-toed boots when working with heavy equipment.
- Park the Machine on Level Ground: Ensure the machine is on a stable and level surface to avoid accidents during the installation process.
- Engage the Parking Brake: Always engage the parking brake and turn off the engine before working on any part of the machine.
