Bobcat 773 Hour Meter Issues: Troubleshooting and Solutions

[MikePhua]

The Bobcat 773 is a popular skid-steer loader known for its reliability and versatility. However, like any piece of machinery, it may encounter issues, particularly with the hour meter, which is crucial for tracking machine usage, maintenance intervals, and overall performance. In this article, we will explore common issues with the Bobcat 773 hour meter, potential causes, and effective solutions to keep your machine running smoothly.
Understanding the Importance of the Hour Meter

1. What is an Hour Meter?
   The hour meter is an essential feature on the Bobcat 773, providing operators with the number of operating hours the machine has accumulated. This information helps schedule routine maintenance tasks like oil changes, filter replacements, and other vital services.
   • Why It Matters: The hour meter serves as a key tool for preventative maintenance, helping to ensure the machine is serviced at the appropriate intervals to maintain optimal performance and prevent unnecessary repairs.
     
2. How the Hour Meter Works
   Typically, the hour meter on the Bobcat 773 works by tracking engine run time. The number displayed on the meter increases as the engine runs, providing an accurate readout of the machine's operational time.
   

Common Hour Meter Issues

1. Hour Meter Not Working
   One of the most common issues reported by Bobcat 773 owners is a non-functional hour meter. When this occurs, it can be challenging to track the machine’s usage and plan for maintenance accordingly.
   • Possible Causes: Several factors can cause the hour meter to stop functioning, including:
     • Faulty Hour Meter Display: The meter itself may malfunction or become damaged.
       
     • Wiring or Electrical Issues: Loose or corroded wiring can interrupt the signal to the hour meter, causing it to display incorrect information or not work at all.
       
     • Blown Fuse: A blown fuse in the electrical system can disrupt the operation of the hour meter.
       
   • Solution: Inspect the hour meter display for visible damage. Check the wiring connections leading to the hour meter to ensure they are clean and secure. If there are signs of damage, repair or replace the faulty wiring. Additionally, check and replace any blown fuses in the system.
     
2. Hour Meter Reading Too High or Too Low
   Another issue that may arise is the hour meter showing inaccurate readings, either too high or too low. This can lead to confusion regarding the machine’s actual usage and cause problems when scheduling maintenance.
   • Possible Causes: The most common reasons for incorrect hour meter readings are:
     • Electrical Interference: In some cases, electrical interference or faulty sensors can cause the meter to register incorrect hours.
       
     • Incorrect Installation or Calibration: If the hour meter was recently replaced or recalibrated, it might not have been installed correctly, leading to erroneous readings.
       
   • Solution: If you suspect the hour meter is providing incorrect readings, check the installation and wiring for any issues. If the hour meter was recently replaced, ensure it was properly calibrated to match the machine's actual operating time.
     
3. Fluctuating or Flickering Hour Meter Display
   Some operators report that their Bobcat 773 hour meter display fluctuates or flickers, making it difficult to read and track the machine’s hours accurately.
   • Possible Causes: The primary cause of a flickering display is typically electrical instability, which may include:
     • Loose or Corroded Electrical Connections: A loose connection or corroded terminal can cause intermittent power supply to the hour meter, resulting in a flickering display.
       
     • Faulty Voltage Regulator: A malfunctioning voltage regulator may cause fluctuations in the power supplied to the meter, leading to erratic behavior.
       
   • Solution: Start by checking all electrical connections, particularly around the hour meter, for signs of looseness or corrosion. Clean the terminals and ensure a secure connection. If the problem persists, test the voltage regulator to ensure it is functioning properly and providing stable voltage to the meter.
     

Maintenance Tips to Avoid Hour Meter Problems

1. Regularly Inspect Electrical Connections
   The reliability of the hour meter is heavily dependent on the electrical system of the Bobcat 773. Regularly inspecting and maintaining the wiring, fuses, and connectors can help prevent many issues from arising.
   • Tip: Periodically clean and inspect the wiring connections leading to the hour meter to ensure they are free from dirt, moisture, and corrosion. Tighten any loose connections and replace worn or damaged wiring.
     
2. Replace Blown Fuses Promptly
   A blown fuse can easily disrupt the operation of the hour meter. Therefore, it’s essential to check and replace fuses regularly to avoid electrical problems.
   • Tip: Always have spare fuses on hand for quick replacement. Refer to the owner’s manual for the specific fuse ratings to ensure proper replacement.
     
3. Keep the Hour Meter Clean
   Dirt, dust, and debris can accumulate around the hour meter display, causing visibility issues. Keeping the meter clean and free from obstructions ensures that you can read the display accurately and monitor machine usage.
   • Tip: Use a soft cloth to wipe the display clean, and ensure the area around the meter remains free of dirt and dust. Be cautious not to damage the display when cleaning it.
     
4. Check the Hour Meter During Regular Maintenance
   During routine maintenance checks, ensure the hour meter is working properly and providing accurate readings. If you notice any irregularities, address them immediately to avoid long-term problems.
   • Tip: Include the hour meter in your regular maintenance schedule. This helps catch issues early and ensures that the machine's maintenance intervals are followed correctly.
     

Conclusion
The Bobcat 773 hour meter is an essential tool for tracking machine usage and ensuring timely maintenance. However, it can sometimes encounter issues such as malfunctioning displays, inaccurate readings, or electrical problems. By understanding the common issues, troubleshooting steps, and maintenance practices, you can keep the hour meter functioning correctly and ensure that your Bobcat 773 continues to perform at its best.
