[MikePhua]

The 2000 Bobcat 337 Mini Excavator is a robust and reliable piece of machinery that has made a significant impact in the construction and landscaping industries. Known for its compact design, versatility, and impressive performance, the Bobcat 337 is ideal for tight job sites and various applications, including digging, trenching, and demolition. In this article, we will take a detailed look at the features, specifications, common issues, and maintenance tips for the Bobcat 337, providing a comprehensive understanding of its capabilities and how to optimize its performance.
Design and Performance of the Bobcat 337 Excavator
The Bobcat 337 is a mini excavator, also known as a crawler excavator, which means it runs on tracks rather than wheels. This provides excellent stability and traction on various surfaces, especially in uneven or soft terrain, where wheeled machines might struggle.
With a net engine horsepower of approximately 35.5 hp (26.5 kW), the Bobcat 337 offers sufficient power for small- to medium-scale excavation projects. Its compact size and exceptional maneuverability make it an excellent choice for confined spaces and urban environments where larger machines would be cumbersome.
One of the most notable features of the Bobcat 337 is its zero tail swing design. This allows the machine to rotate 360 degrees without the tail overhanging, making it easier to work in narrow or congested areas where space is limited. This feature significantly improves safety and efficiency on the job site, as it reduces the risk of damage to surrounding structures and equipment.

• Maximum Reach: Around 17 feet (5.18 meters), allowing the operator to extend further and access hard-to-reach areas.
  
• Travel Speed: 2.7 mph (4.3 km/h), providing sufficient speed for moving between work sites while maintaining stability.
  
• Arm/Boom Lift Capacity: Approximately 3,000 lbs (1,361 kg), giving the excavator enough lift capacity to handle light-to-medium tasks.
  

Key Features of the Bobcat 337 Excavator

1. Zero Tail Swing Design: As previously mentioned, the zero tail swing (ZTS) design allows the Bobcat 337 to rotate 360 degrees without the tail overhanging the track width. This unique feature makes the excavator particularly useful in confined spaces, offering enhanced safety and maneuverability.
   
2. Hydrostatic Drive System: The Bobcat 337 is equipped with a hydrostatic drive system, which provides smooth and precise control over the machine's movement. This system allows the operator to make quick adjustments and increases overall efficiency, especially when working in tight or challenging conditions.
   
3. Joystick Controls: The Bobcat 337 uses joystick controls, which provide a more intuitive and comfortable experience for the operator. The joysticks control both the machine's movement and its functions, such as lifting, digging, and rotating. This layout simplifies operation, reduces operator fatigue, and increases precision.
   
4. High Lift Capacity: Despite its compact size, the Bobcat 337 has a solid lift capacity of approximately 3,000 lbs (1,361 kg). This allows it to lift and move materials effectively, making it useful for a range of tasks, including material handling and grading.
   
5. Compact Size for Tight Spaces: With its narrow width and short length, the Bobcat 337 is ideal for working in areas with limited access or crowded job sites. Its size also makes it easier to transport, especially when towing or loading onto a flatbed truck for movement between locations.
   

Common Issues with the Bobcat 337
While the Bobcat 337 is known for its reliability and performance, like all machinery, it can experience certain issues over time, especially if it is used intensively without proper maintenance. Some common problems associated with the Bobcat 337 include:

1. Hydraulic Leaks: The hydraulic system is a vital part of the Bobcat 337, powering the boom, arm, and other key components. Over time, seals and hoses can wear out or become damaged, leading to hydraulic leaks. Regular inspections of the hydraulic system, including hoses and seals, can help prevent such issues.
   
2. Cooling System Issues: Overheating can become a problem if the cooling system is clogged with dirt or debris, especially when operating in dusty environments. Regular cleaning of the radiator and air filters, along with ensuring the coolant levels are correct, can help prevent overheating and maintain engine performance.
   
3. Track Wear and Tensioning: Tracks are a key feature of the Bobcat 337, providing traction and stability. However, they can wear out over time, especially when used on rough or rocky terrain. Regular inspection of the tracks, as well as ensuring proper tensioning, is important for maintaining optimal performance.
   
4. Electrical Problems: Electrical issues, such as a dead battery or malfunctioning alternator, can occasionally occur in older machines. Regular checks of the battery, alternator, and wiring system can help avoid electrical failures.
   
5. Boom and Arm Wear: The boom and arm are subject to heavy wear, especially when digging or lifting materials regularly. It's important to monitor these components for cracks or excessive wear and replace them when necessary to ensure the machine’s lifting and digging capabilities are not compromised.
   

Maintenance Tips for the Bobcat 337 Excavator
To keep the Bobcat 337 running smoothly and avoid costly repairs, it's important to follow a regular maintenance schedule. Here are some maintenance tips:

1. Hydraulic System Maintenance: Regularly check the hydraulic fluid levels and inspect hoses for any signs of leaks or damage. Replace seals and gaskets as needed to prevent hydraulic issues.
   
2. Track Inspection and Maintenance: Inspect the tracks for wear and damage. Adjust the track tension periodically to ensure they are neither too loose nor too tight. Replace worn-out tracks promptly to maintain stability and performance.
   
3. Cooling System Care: Clean the radiator and air filters regularly to prevent dust and debris buildup, which can hinder airflow and cause overheating. Ensure that coolant levels are adequate.
   
4. Engine and Filter Maintenance: Change the engine oil, replace oil filters, and check the air filter regularly. Clean the engine compartment to prevent the buildup of dirt and debris, which can affect engine performance.
   
5. Electrical System Checks: Inspect the electrical system for any signs of wear or corrosion. Ensure that the battery is charged and properly secured, and replace it when it shows signs of aging.
