Understanding the Bobcat 247B Bogie Wheel: Issues, Causes, and Solutions

[MikePhua]

The Bobcat 247B is a popular compact track loader, known for its versatility and ability to work in a wide variety of terrains. However, like all heavy equipment, it is not immune to mechanical issues. One of the most common problems that operators of the Bobcat 247B face is with the bogie wheel, an essential component in the undercarriage system. Understanding the bogie wheel's role, potential issues, and how to troubleshoot and resolve these problems can ensure the machine operates smoothly for years.
What is the Bogie Wheel in the Bobcat 247B?
The bogie wheel is part of the undercarriage system of a tracked vehicle like the Bobcat 247B. It is a small wheel mounted to the frame that helps support the weight of the machine and provide stability during operation. The main function of the bogie wheel is to distribute the load evenly across the track system, allowing for smoother movement, especially when operating on rough or uneven terrain.
The 247B is equipped with a suspended undercarriage that utilizes multiple bogie wheels, which work in conjunction with other components like the drive sprocket, track tensioner, and rollers. Together, they ensure proper weight distribution, minimize wear on the tracks, and help the machine move efficiently over various surfaces.
Symptoms of Bogie Wheel Problems
Problems with the bogie wheel in the Bobcat 247B can manifest in various ways, affecting performance and causing undue wear on the machine. Some of the most common symptoms include:

• Uneven Track Wear: One of the first signs of a bogie wheel issue is uneven or excessive wear on the tracks. If the bogie wheel is damaged or malfunctioning, it can cause the track to wear unevenly, leading to costly repairs or track replacements.
  
• Track Slipping or Jumping: If the bogie wheel isn't functioning properly, the track may slip or jump, causing erratic movement or a loss of traction. This can make it difficult to operate the machine, especially on slopes or soft ground.
  
• Noise from the Undercarriage: A noisy undercarriage can indicate that the bogie wheel or other parts of the track system are damaged. Grinding, squealing, or knocking sounds may be the result of worn-out bearings or misalignment.
  
• Lack of Smooth Movement: The bogie wheel helps distribute the load and maintain smooth movement. If it's malfunctioning, the machine may struggle to move, and operators may experience a jerky or bumpy ride.
  

Common Causes of Bogie Wheel Issues
Several factors can contribute to bogie wheel problems on the Bobcat 247B. Identifying the root cause is essential to diagnosing and fixing the issue. Some common causes include:
1. Worn-out Bearings
Bogie wheels feature bearings that allow them to rotate smoothly and reduce friction. Over time, these bearings can wear out due to regular use, dirt, debris, and exposure to the elements. Worn bearings can cause the wheel to seize or operate with excessive friction, affecting the overall performance of the undercarriage.
Solution: Inspect the bearings regularly and replace them if they show signs of wear or damage. It’s also important to lubricate the bearings to prevent premature wear.
2. Misalignment
Improper alignment of the bogie wheel can cause uneven wear on the track, reduce the effectiveness of the undercarriage, and lead to premature failure of other components. Misalignment may result from impact damage, improper installation, or wear in the suspension components.
Solution: Check the alignment of the bogie wheel regularly, especially if the tracks show signs of uneven wear. Ensure that the wheel is correctly aligned with the track and that the suspension components are intact.
3. Damaged or Broken Bogie Wheel
The bogie wheel itself can become damaged or broken due to excessive wear, rough handling, or hitting obstacles while operating. A damaged wheel can cause the machine to lose stability, leading to poor performance and unsafe working conditions.
Solution: Replace damaged or broken bogie wheels immediately. Regularly inspect the wheels for cracks, bends, or other signs of damage that could compromise their functionality.
4. Improper Track Tension
Track tension plays a crucial role in the operation of the undercarriage system. If the tracks are too loose or too tight, they can cause unnecessary stress on the bogie wheel and other undercarriage components. Improper tension can lead to abnormal wear patterns on the tracks and bogie wheels.
Solution: Check the track tension periodically and adjust it according to the manufacturer’s specifications. Proper track tension helps ensure smooth operation and extends the lifespan of the undercarriage components.
5. Contaminants and Dirt Build-up
Dirt, mud, and debris can accumulate in the area around the bogie wheel, causing it to become clogged or obstructed. This build-up can lead to excessive wear and tear, as the bogie wheel struggles to rotate freely.
Solution: Regularly clean the undercarriage and remove any dirt, mud, or debris that may have accumulated around the bogie wheel. Proper maintenance can prevent clogs and ensure the wheel operates smoothly.
How to Diagnose and Fix Bogie Wheel Problems
To diagnose and address bogie wheel issues in the Bobcat 247B, follow these steps:
Step 1: Inspect the Bogie Wheel
Begin by inspecting the bogie wheel for visible damage, cracks, or signs of wear. Check the bearings for excessive play and listen for unusual noises when the wheel rotates.
Step 2: Check Track Wear
Examine the tracks for uneven wear or slippage, which could indicate an issue with the bogie wheel. If the wear pattern is abnormal, this could suggest misalignment or malfunctioning bearings.
Step 3: Test the Alignment
Check the alignment of the bogie wheel in relation to the track and the other components of the undercarriage. Ensure that everything is aligned correctly and that there is no excessive movement or wobbling.
Step 4: Adjust Track Tension
Verify the track tension and make adjustments as necessary. If the tracks are too tight or too loose, this could cause stress on the bogie wheel and other parts of the undercarriage.
Step 5: Clean the Undercarriage
Clean the area around the bogie wheel and remove any dirt, mud, or debris. This will ensure the wheel can rotate freely and prevent premature wear.
Preventive Maintenance Tips for the Bobcat 247B Undercarriage
To avoid bogie wheel problems and other undercarriage issues, regular maintenance is essential. Here are some tips for keeping the Bobcat 247B in top condition:

• Inspect the undercarriage regularly: Regularly check the bogie wheels, tracks, and suspension components for signs of wear and damage.
  
• Lubricate components: Ensure that all moving parts, including the bogie wheel bearings, are properly lubricated to reduce friction and wear.
  
• Clean the undercarriage: Keep the undercarriage clean and free from debris that could obstruct the bogie wheel or cause excessive wear.
  
• Check track tension: Maintain proper track tension according to the manufacturer’s specifications to prevent undue stress on the bogie wheel and other components.
  

Conclusion
The bogie wheel plays a critical role in the smooth operation of the Bobcat 247B. Problems with the bogie wheel, such as worn bearings, misalignment, or damage, can significantly impact the machine’s performance and cause costly repairs if not addressed promptly. By regularly inspecting and maintaining the undercarriage system, operators can prevent issues and ensure the machine operates efficiently.
If you experience bogie wheel problems that cannot be easily resolved through basic maintenance, it's advisable to consult a professional technician to perform a thorough inspection and carry out necessary repairs. Proper care and attention to the bogie wheel and other undercarriage components will extend the life of your Bobcat 247B and improve its overall reliability on the job.
