Vermeer 672 Deutz Engine Model: Understanding and Troubleshooting

[MikePhua]

The Vermeer 672 is a robust machine known for its exceptional performance in the trenching and utility installation sectors. Powered by a Deutz engine, it offers durability and efficiency, particularly for tough tasks. However, like all machinery, issues may arise with the engine, affecting the overall performance. In this article, we will dive into the key aspects of the Vermeer 672's Deutz engine, addressing common issues and solutions, and offering guidance on maintaining its optimal function.
The Importance of the Deutz Engine in the Vermeer 672
The Deutz engine used in the Vermeer 672 is well-regarded for its fuel efficiency, power output, and reliability. Deutz engines are commonly found in construction and agricultural equipment due to their ability to handle demanding applications while maintaining relatively low maintenance needs. The engine's robust design is an ideal match for the Vermeer 672, a machine designed to tackle hard ground conditions and carry out continuous trenching operations.
Common Engine Problems in the Vermeer 672 and Their Solutions
Despite its reputation for reliability, the Deutz engine in the Vermeer 672 is not immune to issues. Many of these problems stem from wear and tear over time, especially when the machine is used for long hours in tough conditions. Below are some of the most frequently encountered problems and their possible solutions.
1. Engine Not Starting
A common issue faced by Vermeer 672 owners is engine starting problems. This can occur for a variety of reasons, including fuel system issues, electrical malfunctions, or problems with the engine's starter motor.
Possible Causes:

• Battery Issues: A weak or dead battery is often the cause of engine starting failures. If the battery voltage drops too low, it won’t provide sufficient power to the starter motor.
  Solution: Check the battery voltage using a multimeter. If it reads low, try charging it or replace the battery if it is old and no longer holds a charge.
  
• Fuel Delivery Problems: The fuel filter may be clogged, or the fuel pump may not be working effectively, leading to a lack of fuel reaching the engine.
  Solution: Inspect the fuel lines and filter for blockages, and replace any parts that appear damaged or clogged. Ensure the fuel pump is functioning correctly.
  
• Electrical Faults: The Vermeer 672’s electrical system, including the starter motor and solenoid, could also be at fault.
  Solution: Check the electrical connections and wires for any loose or corroded parts. If necessary, replace the starter motor or solenoid to restore proper functionality.
  

2. Overheating Issues
Overheating is another concern for those operating the Vermeer 672, particularly during long, hot days of trenching or digging in challenging conditions. The engine relies heavily on proper cooling to prevent overheating.
Possible Causes:

• Low Coolant Levels: Insufficient coolant can cause the engine to overheat quickly, especially when under load.
  Solution: Regularly check the coolant level and top it up with the recommended coolant type. Ensure that there are no leaks in the cooling system.
  
• Clogged Radiator: Dirt, debris, or buildup in the radiator can block airflow, leading to insufficient cooling.
  Solution: Clean the radiator regularly, especially if the machine has been working in dusty or muddy conditions. Ensure there are no obstructions in front of the radiator that could block airflow.
  
• Thermostat Failure: If the thermostat is stuck in the closed position, the coolant cannot circulate properly, causing the engine to overheat.
  Solution: Replace the thermostat if it appears faulty or if it is not functioning correctly.
  

3. Decreased Power Output
Over time, you may notice that the Vermeer 672 with its Deutz engine begins to show signs of decreased power output. This can significantly affect the performance of the machine, especially in demanding conditions.
Possible Causes:

• Air Filter Clogging: A clogged air filter can restrict airflow to the engine, leading to inefficient combustion and loss of power.
  Solution: Inspect the air filter regularly and replace it if it appears dirty or clogged. Use the correct type of filter as specified by the manufacturer.
  
• Fuel Injector Problems: Dirty or faulty fuel injectors can cause incomplete combustion, leading to reduced engine power and efficiency.
  Solution: Have the fuel injectors cleaned or replaced if necessary. Regular maintenance of the fuel system is essential for preventing performance issues.
  
• Turbocharger Failure: If the Vermeer 672 is equipped with a turbocharged Deutz engine, a malfunction in the turbocharger can lead to reduced power output.
  Solution: Inspect the turbocharger for any signs of damage or wear. If it is not functioning properly, it may need to be repaired or replaced.
  

4. Excessive Smoke Emission
Excessive smoke from the exhaust can be an alarming issue, indicating potential engine problems. Depending on the color of the smoke, the cause can vary.
Possible Causes:

• Blue Smoke: Blue smoke typically indicates that oil is burning in the engine, possibly due to worn valve seals, piston rings, or cylinder walls.
  Solution: Inspect the engine for signs of oil leaks, and check the valve seals and piston rings. Replacing these parts may be necessary to stop the blue smoke.
  
• Black Smoke: Black smoke indicates that the engine is burning too much fuel, possibly due to clogged air filters, malfunctioning fuel injectors, or a dirty turbocharger.
  Solution: Replace the air filter, clean or replace the fuel injectors, and ensure that the turbocharger is functioning properly.
  
• White Smoke: White smoke is often a sign that coolant is entering the combustion chamber, which could indicate a blown head gasket or a cracked cylinder head.
  Solution: If white smoke persists, check for coolant leaks around the engine. A head gasket replacement or repair may be required.
  

5. Fuel Efficiency Problems
A common complaint among owners of the Vermeer 672 is a noticeable decline in fuel efficiency, which can lead to increased operating costs.
Possible Causes:

• Fuel System Blockages: A clogged fuel filter or malfunctioning fuel pump can reduce the engine’s efficiency by restricting fuel flow.
  Solution: Check the fuel system, including the filter and pump, for blockages or wear. Replacing the fuel filter and cleaning the system can help restore optimal performance.
  
• Improper Engine Timing: If the engine timing is not set correctly, it can affect combustion efficiency, leading to poor fuel economy.
  Solution: Have the engine timing checked and adjusted as needed by a professional mechanic.
  

6. Regular Maintenance for Longevity
Like any heavy machinery, regular maintenance is essential to keep the Vermeer 672 with a Deutz engine running smoothly. Some key maintenance tasks include:

• Oil Changes: Regular oil changes are essential to prevent engine wear and tear. Always use the recommended oil type and change it at the intervals specified in the operator's manual.
  
• Filter Inspections: Air filters, fuel filters, and oil filters should all be inspected and replaced periodically to ensure the engine runs efficiently.
  
• Cooling System Maintenance: Check coolant levels and inspect the radiator and hoses for signs of leaks or wear.
  
• Drive Belt Inspections: Inspect the drive belts for any signs of cracking or wear, as a damaged belt can lead to engine failure or overheating.
  

Real-World Example: A Contractor’s Experience with the Vermeer 672
A contractor working on a large pipeline project with a Vermeer 672 experienced issues with the engine intermittently overheating during extended use. After inspecting the cooling system, they found that the radiator was clogged with debris, restricting airflow. After cleaning the radiator and topping up the coolant, the overheating issue was resolved, and the machine continued to perform efficiently for the rest of the project. This incident highlighted the importance of routine maintenance and attention to the cooling system.
Conclusion
The Vermeer 672 with its Deutz engine is a powerful machine designed for demanding tasks, but it requires regular maintenance and attention to stay in optimal condition. Whether dealing with engine starting problems, overheating, loss of power, or fuel efficiency issues, diagnosing and addressing the problem early can help avoid costly repairs and downtime. Following a regular maintenance schedule, using high-quality parts, and staying vigilant for signs of wear will keep your Vermeer 672 running at its best for years to come.
