The Caterpillar 215 is a versatile and reliable track loader, but like any heavy machinery, it can experience mechanical issues that may leave operators in a bind. One such issue is when only one track works, leaving the machine unable to move efficiently. In this article, we'll explore the potential causes for this issue and provide a detailed troubleshooting guide for diagnosing and fixing it.
Understanding the Issue
When one track is not functioning on a Cat 215, the machine will struggle to move in a straight line, and the operator will have difficulty controlling it. This issue can be frustrating, but it's often caused by a problem with the drive system, hydraulic circuits, or the track itself. It’s crucial to understand the underlying components of the system to troubleshoot effectively.
Common Causes of One Track Not Working
Several factors can cause one track to stop functioning, and each requires a different approach for diagnosis and repair. Here are the most common causes:
Now that we understand the potential causes of the issue, let's dive into the steps needed to troubleshoot and resolve the problem of one track not working.
Step 1: Check Hydraulic Fluid Levels
Start by inspecting the hydraulic fluid levels in the machine. Low hydraulic fluid is a common culprit when it comes to power loss in the tracks. Check the hydraulic reservoir and top it off if needed. Also, look for signs of leaks in the hydraulic system. Leaking hoses or fittings can cause a loss of pressure, preventing the track from operating correctly.
Step 2: Inspect the Hydraulic Pump and Valves
If the fluid levels are adequate, the next step is to inspect the hydraulic pump and valves. Look for any signs of wear or damage. A malfunctioning hydraulic pump can cause one of the tracks to lose power. Similarly, a faulty valve can block fluid flow to the drive motors. If you suspect any issues, consider cleaning or replacing the valves, or check the hydraulic pump pressure to ensure it’s operating at optimal levels.
Step 3: Examine the Drive Motor
Next, move on to the drive motor. Start by checking the connections to the motor, including the hydraulic lines and wiring. Look for any visible damage or leaks. A damaged motor may need to be replaced or repaired. You can also test the motor’s performance by engaging the track and observing if the motor is receiving the correct hydraulic pressure.
Step 4: Inspect the Track and Drive Gear
If the motor appears to be working correctly, the next potential issue could be the track or drive gear. Inspect the track for any obvious damage, such as tears or excessive wear. A damaged sprocket or gear could prevent the track from moving. If there are no visible issues with the track itself, check the drive sprocket for any missing or damaged teeth. Replacing a worn-out sprocket or gear will help restore full functionality.
Step 5: Test the Electrical System
If all of the above checks out, it’s time to inspect the electrical system. A malfunctioning sensor or wiring issue can interrupt the control signals that manage the track drive motors. Start by inspecting the electrical connections to the motors and the ECU. Use a multimeter to check for proper voltage and continuity. If the electrical system is compromised, you may need to repair or replace damaged wiring, sensors, or components of the ECU.
Step 6: Check Track Tension
Finally, check the tension of the tracks. Both tracks should have equal tension to ensure proper operation. If one track is too tight or loose, adjust the tension according to the manufacturer’s guidelines. This will help ensure that both tracks function correctly.
Preventing Future Issues
Once you’ve identified and fixed the problem, it’s essential to take steps to prevent it from recurring. Here are some tips for maintaining your Cat 215’s track system:
Dealing with a Cat 215 that only has one working track can be frustrating, but with a systematic approach, most issues can be identified and resolved. Whether it’s a hydraulic system failure, damaged drive motor, or worn-out track components, a thorough inspection of the key systems will help pinpoint the root cause. By following these troubleshooting steps and performing regular maintenance, you can ensure that your Cat 215 remains a reliable workhorse, keeping both tracks in action and the machine running at its best.

Common Causes of One Track Not Working
Several factors can cause one track to stop functioning, and each requires a different approach for diagnosis and repair. Here are the most common causes:
- Hydraulic System Failure
The Cat 215 uses hydraulics to power the drive motors that turn the tracks. If the hydraulic pump is failing, or there is a blockage in the hydraulic lines, it can result in one of the tracks losing power. A lack of hydraulic fluid or a problem with the hydraulic valves could also prevent the drive motors from engaging properly.
- Drive Motor Issues
Each track on a track loader like the Cat 215 is driven by a dedicated hydraulic motor. If one motor fails or has an internal issue, it can cause the track associated with it to stop working. Problems with the motor's seals, bearings, or internal components can lead to power loss.
- Damaged or Broken Track Drive Gear
A broken or damaged gear or sprocket can cause a track to fail. This typically occurs after prolonged use or when the machine has encountered harsh conditions. A malfunction in the drive gear will result in one track losing power, rendering it inoperable.
- Track Tension Problems
If the track is too loose or too tight, it can affect the performance of the track drive system. A track that is too loose might slip, while a track that is too tight could cause excessive wear and mechanical strain. In both cases, the track will not function properly, potentially leading to the machine moving on only one track.
- Electrical Issues
The Cat 215 is equipped with an electronic control system that manages the hydraulic system and other vital components. If there's an electrical malfunction, it could cause a problem in the communication between the system and the track motors. A faulty sensor, wiring issue, or ECU failure could prevent the track from receiving the proper signals to engage.
