Introduction to CAT 277B and Its Track System
The CAT 277B is a versatile compact track loader used for various construction and landscaping tasks. Like any heavy equipment, it relies heavily on its track system for stability and maneuverability. However, one common issue that operators face is when one of the tracks, such as the right side track, stops functioning. This problem can affect the machine’s performance and overall productivity, making it essential to identify and fix the root cause promptly.
Common Causes of Inoperative Tracks
Several potential causes contribute to a malfunctioning right-side track on the CAT 277B. Below are some of the most frequently reported issues:
To resolve the issue with the right-side track, operators can follow these troubleshooting steps:
The CAT 277B is a powerful and reliable track loader, but like all machines, it requires regular maintenance to perform at its best. If the right side track becomes inoperative, it is crucial to diagnose the issue correctly and take appropriate action. By addressing potential problems with the hydraulic system, drive motor, track tension, undercarriage, or electrical components, operators can restore the full functionality of the machine and avoid further downtime. Regular inspections and timely repairs will ensure that the CAT 277B continues to operate efficiently and effectively for years to come.

Common Causes of Inoperative Tracks
Several potential causes contribute to a malfunctioning right-side track on the CAT 277B. Below are some of the most frequently reported issues:
- Hydraulic System Failure
The track drive on the CAT 277B is powered by the hydraulic system. If the right side track is inoperative, it could indicate a problem with the hydraulic fluid or pump. A low hydraulic fluid level, air in the system, or a faulty hydraulic pump can disrupt the flow of fluid to the track drive motor, causing the track to stop moving.
- Drive Motor Malfunction
The drive motor is essential for powering the tracks. A malfunction in the drive motor can result in one side of the tracks not functioning. Common symptoms include overheating, irregular operation, or complete failure of the motor. It is recommended to inspect the motor for wear or damage, including checking the electrical components and connections that control the motor.
- Track Tension Issues
Incorrect track tension can also affect the movement of the tracks. If the right track is too loose or too tight, it may not move as efficiently, or it may cause damage to other components. Regularly checking the track tension and adjusting it according to the manufacturer’s guidelines can prevent these issues.
- Undercarriage Problems
Issues with the undercarriage, such as damaged rollers, sprockets, or idlers, can contribute to the failure of one of the tracks. Worn or broken parts can cause the right side track to stop functioning, so regular inspection and maintenance of the undercarriage are critical.
- Electrical Issues
The CAT 277B features electronic controls that manage track movement. If there is an electrical fault, such as a blown fuse, faulty wiring, or a malfunctioning control module, it can cause the right side track to become inoperative. Inspecting and diagnosing the electrical system can help pinpoint the issue.
To resolve the issue with the right-side track, operators can follow these troubleshooting steps:
- Check Hydraulic Fluid Levels
Ensure that the hydraulic fluid is at the proper level and that it is clean. If the fluid is low, refill it with the recommended type of hydraulic oil. If contamination is suspected, replace the fluid and filters.
- Inspect the Hydraulic Pump and Motor
Check for any signs of leaks, unusual noise, or overheating from the hydraulic pump and motor. If a failure is detected, it may be necessary to replace the faulty components.
- Examine the Drive Motor
Inspect the right-side drive motor for damage or wear. Testing the motor’s electrical components and connections can help identify electrical issues that might prevent the motor from functioning properly.
- Adjust Track Tension
If the track tension is incorrect, adjust it according to the manufacturer’s specifications. Proper track tension ensures that the tracks operate smoothly and efficiently.
- Inspect the Undercarriage
Examine the undercarriage components, including the rollers, sprockets, and idlers, for wear and tear. Replace any worn or damaged parts as necessary.
