The Dresser TD-20E, a powerful crawler tractor first introduced in the late 1960s, remains a reliable machine for heavy-duty construction and earth-moving projects. With its robust diesel engine and rugged design, it’s been a staple in industries ranging from agriculture to mining. However, as with any older machinery, maintaining and troubleshooting the TD-20E is essential to keep it running smoothly.
This guide focuses on common issues faced by operators of the Dresser TD-20E, particularly from the perspective of troubleshooting, diagnostics, and necessary repairs. It also offers tips on how to extend the lifespan of the equipment while ensuring optimal performance.
Understanding the Dresser TD-20E
The Dresser TD-20E is a crawler tractor designed to tackle tough jobs such as pushing large quantities of dirt, clearing roads, and handling material in construction sites. Its weight, powerful engine, and durable tracks make it suitable for demanding operations. However, as these machines age, they may face several mechanical issues that require attention.
Common Issues with the Dresser TD-20E
1. Hydraulic Problems
One of the most commonly reported issues with older heavy equipment like the TD-20E is problems with the hydraulic system. Symptoms include slow or erratic movement of the lift arms, dozer blade, or steering.
Possible Causes:
Another frequent issue with the Dresser TD-20E involves starting the engine, particularly if the machine has been sitting idle for an extended period. Inadequate starting performance can be attributed to various factors, including fuel system issues, battery problems, or electrical faults.
Possible Causes:
Overheating is a common issue with older machines, especially in extreme weather conditions or after prolonged use. If the engine temperature rises too high, it can lead to severe damage if not addressed immediately.
Possible Causes:
The steering on a Dresser TD-20E can sometimes become unresponsive, making it difficult to maneuver. This issue could be a result of the mechanical steering system or hydraulic steering components.
Possible Causes:
Keeping the Dresser TD-20E in good working condition requires regular maintenance. Here are some general maintenance tips:
Troubleshooting and maintaining the 1969 Dresser TD-20E crawler tractor is essential to extend its life and keep it performing well. While the hydraulic system, starting issues, engine overheating, and steering problems are some of the most common problems, timely diagnostics and repairs can prevent more serious issues. Regular maintenance, such as checking fluid levels, inspecting key components, and replacing worn parts, is key to ensuring the machine remains a reliable workhorse.
By paying attention to the signs of wear and staying on top of maintenance, operators can continue to get the most out of their Dresser TD-20E, ensuring it serves its purpose for many more years in the field.

Common Issues with the Dresser TD-20E
1. Hydraulic Problems
One of the most commonly reported issues with older heavy equipment like the TD-20E is problems with the hydraulic system. Symptoms include slow or erratic movement of the lift arms, dozer blade, or steering.
Possible Causes:
- Low Hydraulic Fluid: Check the fluid levels regularly and top off if necessary. Running the system with insufficient fluid can cause the pump to run dry, potentially causing significant damage.
- Hydraulic Pump Failure: If the pump is faulty, the tractor will lack the necessary hydraulic pressure for operation. Over time, wear and tear on the pump can degrade its performance.
- Clogged Filters: The hydraulic filters might become clogged with debris or dirt, limiting the flow of fluid and reducing the system’s overall performance.
- Inspect the fluid level and top it off as needed.
- Check the hydraulic pump for signs of wear or leaks.
- Replace the hydraulic filters to maintain proper fluid flow and prevent system malfunctions.
Another frequent issue with the Dresser TD-20E involves starting the engine, particularly if the machine has been sitting idle for an extended period. Inadequate starting performance can be attributed to various factors, including fuel system issues, battery problems, or electrical faults.
Possible Causes:
- Weak or Dead Battery: A weak battery or poor connections can prevent the engine from turning over. Ensure the battery is fully charged, and the terminals are clean and tight.
- Fuel Delivery Problems: Clogged fuel filters or a malfunctioning fuel pump can hinder the engine’s ability to start.
- Starter Motor Issues: The starter motor may wear out over time and require replacement if the engine fails to turn over.
- Check and clean the battery terminals, and ensure the battery is charged.
- Inspect the fuel system, including the fuel filters and pump, for any blockages or wear.
- Test the starter motor to confirm whether it is functioning correctly. If the starter is faulty, it may need to be replaced.
Overheating is a common issue with older machines, especially in extreme weather conditions or after prolonged use. If the engine temperature rises too high, it can lead to severe damage if not addressed immediately.
Possible Causes:
- Coolant Leaks: Over time, hoses and seals can deteriorate, leading to coolant leaks. A loss of coolant will result in the engine overheating.
- Clogged Radiator: Dirt and debris can accumulate in the radiator, reducing its cooling efficiency.
- Faulty Thermostat: If the thermostat is stuck in the closed position, it will prevent coolant from circulating properly, causing the engine to overheat.
- Inspect the coolant system for leaks, and replace any worn-out hoses or seals.
- Clean the radiator to ensure it’s free of debris.
- Check the thermostat for proper operation and replace it if it’s malfunctioning.
The steering on a Dresser TD-20E can sometimes become unresponsive, making it difficult to maneuver. This issue could be a result of the mechanical steering system or hydraulic steering components.
Possible Causes:
- Low Hydraulic Fluid: A lack of hydraulic fluid in the steering system can result in unresponsive steering. Ensure that the system has the correct fluid level.
- Worn Steering Components: Over time, the steering linkage and components can wear down, causing a lack of precision in the steering.
- Hydraulic System Malfunctions: A problem in the hydraulic system, such as a malfunctioning steering valve, can also cause steering issues.
- Inspect the hydraulic fluid levels regularly.
- Check the steering components for wear and replace any worn-out parts.
- Test the hydraulic system for any leaks or malfunctions.
Keeping the Dresser TD-20E in good working condition requires regular maintenance. Here are some general maintenance tips:
- Engine Maintenance: Regularly check the engine oil and replace it as recommended by the manufacturer. Replace the oil filter to prevent engine wear.
- Track Inspection: The tracks should be checked frequently for wear, damage, or loose bolts. Tighten or replace the tracks as necessary to avoid damage to the undercarriage.
- Transmission Fluid: Ensure the transmission fluid is topped off to prevent overheating and excessive wear on the gearbox.
- Cooling System: Clean the radiator and check for leaks in the cooling system to prevent engine overheating.
