Signs That Track Stops May Need Attention
It’s important to monitor your Bobcat 331 regularly to identify early signs of track stop issues. Here are some signs that may indicate it’s time to inspect and possibly replace the track stops:- Uneven Track Wear: If you notice uneven wear on the tracks, especially on one side, it could be a sign of improper track alignment due to worn track stops.
- Track Slipping: If the machine’s tracks are slipping or coming off the undercarriage, this is a clear indication that the track stops are not functioning properly.
- Noise During Operation: Unusual noises, such as grinding or clanking, while the machine is in operation, may indicate that the track stops are loose or damaged.
- Visible Damage: Any cracks, breaks, or visible damage to the track stops should be addressed immediately. Worn-out or broken track stops are ineffective and can cause further damage to the tracks and undercarriage.
Steps for Troubleshooting and Repairing Bobcat 331 Track Stops
If you notice any of the issues above, it’s essential to inspect the track stops to diagnose the problem and take appropriate action. Here are the key steps for troubleshooting and repairing the track stops:
1. Inspect the Track Stops for Damage
Begin by visually inspecting the track stops to check for signs of damage, such as cracks or bends. Use a flashlight to inspect areas that may be difficult to see clearly. If you find any damage, the track stops will need to be replaced.
2. Check Track Alignment- Use a Level: Check if the tracks are aligned properly. You can use a level to ensure that the tracks are running straight and that the track stops are effectively limiting any lateral movement.
- Check for Uneven Wear: Look for signs of uneven wear on the tracks. If the tracks are worn more on one side, this could indicate that the track stops are not keeping the tracks aligned correctly.
3. Examine Track Tension
Incorrect track tension can cause issues with the track stops. If the tension is too loose, the track may move laterally, causing the track stops to wear out prematurely. On the other hand, excessive tension can cause unnecessary strain on the tracks and the track stops.
To adjust the track tension, follow these steps:- Loosen the Tensioning Bolt: Use a wrench to loosen the tensioning bolt located on the track tensioning system.
- Adjust the Tension: Tighten or loosen the bolt until the track has the proper amount of tension. Ensure the tracks are neither too tight nor too loose.
- Check the Alignment: After adjusting the tension, check if the tracks are aligned properly with the track stops.
4. Clean the Track Stop Area
Clean any dirt, mud, or debris that has accumulated around the track stops. Use a pressure washer or a hose to flush out the debris. This will ensure that the track stops can move freely and effectively control the movement of the tracks.
5. Replace Worn or Damaged Track Stops
If the track stops are found to be damaged or excessively worn, they will need to be replaced. To do this:- Lift the Track Loader: Use a jack or lifting equipment to raise the machine off the ground.
- Remove the Track: Remove the track from the loader to access the track stops. This may require you to remove some additional components, such as the track chain or sprockets.
- Remove the Old Track Stops: Use a wrench to remove the bolts securing the track stops in place. Be sure to note the positioning of the old track stops for proper installation of the new ones.
- Install New Track Stops: Place the new track stops in the same position as the old ones and tighten the bolts securely.
- Reinstall the Track: Once the track stops are replaced, reinstall the track and make necessary adjustments to ensure it runs smoothly.
6. Test the Machine
After replacing or adjusting the track stops, test the Bobcat 331 to ensure that the tracks are properly aligned and that the machine operates smoothly. Take it for a short drive on flat ground, and check for any issues with track slippage, noise, or alignment.
Preventative Maintenance Tips
To avoid common track stop issues and ensure the longevity of your Bobcat 331, consider the following preventative maintenance tips:- Regular Inspection: Regularly inspect the track stops for wear and damage. This will help you catch any issues early before they become serious problems.
- Clean the Tracks: Keep the track area clean by removing dirt, mud, and debris after each use. This will prevent buildup that can impair the function of the track stops.
- Monitor Track Tension: Regularly check the track tension and adjust it as necessary. Proper tension is crucial for maintaining track alignment and preventing unnecessary wear on the track stops.
- Lubricate Moving Parts: Periodically lubricate the moving parts of the track system, including the track stops. Proper lubrication will reduce friction and wear, extending the lifespan of the components.
Conclusion
The track stops on a Bobcat 331 play a vital role in ensuring the tracks remain properly aligned and functioning. Regular maintenance, inspection, and timely repairs are crucial for preventing issues like track misalignment, slippage, and excessive wear. By understanding the importance of track stops and following the troubleshooting and maintenance procedures outlined above, you can keep your Bobcat 331 running efficiently and extend the life of its undercarriage system.
