The 1981 TD-8E bulldozer is part of the International Harvester series, renowned for its durability and performance in demanding environments. Over the years, the TD-8E has earned a reputation for its ability to perform heavy-duty tasks like land clearing, road construction, and material handling. However, like any heavy machinery, it requires maintenance and repair from time to time to keep it running efficiently.
One of the common issues that operators encounter with the TD-8E is problems with the track adjuster. The track adjuster is a crucial part of the undercarriage system, responsible for maintaining the correct tension on the tracks. If the track adjuster fails, it can lead to poor track performance, excessive wear, and even potential damage to other components of the undercarriage.
The Importance of the Track Adjuster in Bulldozers
The track adjuster plays a key role in keeping the undercarriage of a bulldozer operating smoothly. The undercarriage is one of the most important parts of any tracked vehicle, as it directly impacts the machine’s ability to move across rough terrain.
In a bulldozer, the track adjuster is responsible for maintaining the correct tension on the tracks. If the tension is too tight, it can cause excessive wear and stress on the tracks, while too loose a tension can lead to the track derailing. Properly adjusting the track tension helps to optimize the life of the tracks and ensures the bulldozer’s ability to perform tasks without unnecessary delays or downtime.
Common Problems with the TD-8E Track Adjuster
Over time, the track adjuster on the TD-8E can develop a variety of issues, which may require repair or replacement. Some of the most common problems include:
Repairing the track adjuster on the TD-8E can be complex, but with the right tools and knowledge, it can be done successfully. Here are the general steps involved in repairing the track adjuster:
Preventative maintenance is key to extending the lifespan of the track adjuster and avoiding costly repairs. Here are some important maintenance tips:
Repairing and maintaining the track adjuster on a 1981 TD-8E bulldozer is an important task for ensuring the longevity and performance of the machine. Regular inspections and proactive maintenance can prevent costly repairs and downtime. By addressing common issues such as leaking seals, hydraulic malfunctions, and physical damage promptly, operators can keep their TD-8E bulldozer running efficiently on the job site. Properly maintaining the track adjuster not only extends the life of the machine but also improves safety and productivity on the worksite.

Common Problems with the TD-8E Track Adjuster
Over time, the track adjuster on the TD-8E can develop a variety of issues, which may require repair or replacement. Some of the most common problems include:
- Leaking Seal or Damaged Seal Housing
The track adjuster typically uses a sealed hydraulic system to maintain the correct tension. When the seals fail, hydraulic fluid can leak out, causing a loss of pressure. This results in the track adjuster losing its ability to adjust properly, which can lead to the tracks becoming too tight or too loose.- Causes: Worn seals, aging rubber materials, and excessive pressure can cause seals to degrade over time.
- Symptoms: Leaking hydraulic fluid, difficulty in adjusting the track tension, or uneven track wear.
- Causes: Worn seals, aging rubber materials, and excessive pressure can cause seals to degrade over time.
- Hydraulic System Malfunctions
The hydraulic system is crucial for the operation of the track adjuster. If there are issues such as low hydraulic fluid levels, contamination, or a failing pump, it can impact the functionality of the adjuster. Without sufficient hydraulic pressure, the adjuster won't be able to maintain the correct track tension, leading to potential damage.- Causes: Hydraulic fluid leakage, air in the system, or faulty components such as the pump or valve.
- Symptoms: Difficulty in adjusting the track, jerky or unresponsive movement, or visible hydraulic leaks.
- Causes: Hydraulic fluid leakage, air in the system, or faulty components such as the pump or valve.
- Physical Damage to the Track Adjuster Components
Physical damage to the adjuster, such as cracks or wear in the housing, can impair its ability to function properly. This could be due to normal wear and tear, impacts from debris, or improper handling during maintenance procedures.- Causes: Operating in harsh conditions, improper installation or handling, or general wear.
- Symptoms: Visible cracks in the housing, difficulty adjusting the track, or failure to maintain tension.
- Causes: Operating in harsh conditions, improper installation or handling, or general wear.
Repairing the track adjuster on the TD-8E can be complex, but with the right tools and knowledge, it can be done successfully. Here are the general steps involved in repairing the track adjuster:
- Inspect the Track and Track Adjuster
The first step is to inspect the entire undercarriage system, including the tracks, rollers, and adjuster. Look for visible signs of wear or damage on the track and adjuster, including leaks, cracks, or abnormal tension in the track. Take note of any issues before proceeding with repairs.
- Drain the Hydraulic Fluid
If the track adjuster is operating on hydraulic power, begin by draining the hydraulic fluid. This step is crucial for preventing fluid spillage and ensuring a clean working environment when repairing the system.
- Remove the Track Adjuster
In many cases, removing the entire track adjuster may be necessary for thorough inspection and repair. This typically involves detaching the adjuster from the undercarriage system using the appropriate tools. Depending on the model, this may involve removing bolts or pins that secure the adjuster in place.
- Replace Damaged Seals or Components
If the issue is related to a leaking seal or other damaged components, replace the faulty parts with new, OEM (Original Equipment Manufacturer) replacements. Pay close attention to the quality of seals, gaskets, and o-rings to ensure that they will provide a proper seal once reassembled.
- Test the Adjuster and Hydraulic System
Once repairs are completed, it’s important to test the track adjuster before reassembly. Fill the hydraulic system with fresh fluid, then operate the adjuster to ensure it is functioning correctly. Check for leaks and confirm that the track tension is adjustable across its full range.
- Reinstall the Track Adjuster
After confirming that the adjuster is functioning properly, reinstall it into the undercarriage. Make sure all bolts, pins, and components are tightened to manufacturer specifications to avoid further issues.
- Final Check and Adjustment
Finally, check the overall track tension and make any final adjustments to ensure the machine is operating smoothly. This will ensure that the track is neither too tight nor too loose, preventing excessive wear and ensuring optimal performance.
Preventative maintenance is key to extending the lifespan of the track adjuster and avoiding costly repairs. Here are some important maintenance tips:
- Regular Inspection
Perform regular inspections of the track adjuster and surrounding components. Look for signs of wear, leaks, or physical damage. Catching issues early can prevent more significant problems from developing.
- Hydraulic Fluid Maintenance
Keep an eye on the hydraulic fluid level and condition. Low or dirty fluid can cause poor performance and damage to the adjuster. Always replace the fluid with the recommended type and clean the system regularly.
- Proper Storage and Usage
When using the bulldozer in harsh conditions, ensure that the machine is properly stored and maintained. Avoid excessive use in extreme environments that could cause undue stress on the undercarriage system.
- Seal Replacement
Seals are prone to wear over time. Be proactive in replacing them during regular maintenance intervals, even if they are not yet leaking. This will prevent more significant hydraulic issues in the future.
Repairing and maintaining the track adjuster on a 1981 TD-8E bulldozer is an important task for ensuring the longevity and performance of the machine. Regular inspections and proactive maintenance can prevent costly repairs and downtime.
