Disconnecting the Hour Meter on a John Deere 50G Excavator
#1
Introduction to the John Deere 50G Excavator
The John Deere 50G is a compact, yet powerful excavator, often used for digging, trenching, and landscaping tasks. Like most heavy equipment, it has an hour meter that tracks the hours the machine has been in operation. This hour meter is essential for scheduling maintenance, service intervals, and ensuring the equipment operates efficiently over its lifespan.
Reasons for Disconnecting the Hour Meter
There are instances when operators or owners might consider disconnecting the hour meter. Common reasons might include:
  • Maintenance or Service Needs: Sometimes, disconnecting the hour meter is necessary for maintenance or repairing issues in the electrical system.
  • Used Equipment Purchases: Buyers of used equipment may want to reset or disconnect the hour meter as part of preparing the machine for resale or re-certification.
  • Malfunctioning Meter: If the hour meter is not functioning correctly or has become stuck, disconnecting it might be a temporary solution until a new meter is installed or repaired.
Steps to Disconnect the Hour Meter
The process of disconnecting the hour meter on a John Deere 50G involves the following steps:
  1. Locate the Hour Meter: The hour meter is typically found in the operator's cabin, usually on the dashboard or the instrument panel.
  2. Disconnect the Battery: For safety, it’s recommended to disconnect the battery before working on the electrical system. This reduces the risk of electrical shocks or accidental short circuits.
  3. Access the Hour Meter Wiring: Depending on the model and setup, you may need to remove the panel or dashboard to access the wiring that connects the hour meter to the machine’s electrical system.
  4. Identify the Wiring for the Hour Meter: Once you have access to the wiring, locate the wires connected to the hour meter. There will typically be a power wire and a signal wire.
  5. Disconnect the Wires: Carefully disconnect the power and signal wires from the hour meter. This will stop the meter from tracking operating hours.
  6. Reassemble the Panel: After the hour meter is disconnected, reassemble the panel and ensure that all components are secure.
  7. Reconnect the Battery: Once the work is complete, reconnect the battery.
Important Considerations
Before disconnecting the hour meter, it is essential to consider the implications:
  • Warranty Issues: Disconnecting the hour meter can void any warranties or service contracts, as it may be seen as tampering with the machine’s original specifications.
  • Record Keeping: If you disconnect the meter, it’s crucial to maintain accurate records of the machine’s operation hours manually. This ensures you don’t miss necessary maintenance schedules.
Reconnecting the Hour Meter
In cases where the hour meter was disconnected for repairs or maintenance, it may need to be reconnected after the work is completed. To reconnect, follow the reverse steps of the disconnection process and ensure that the hour meter is functioning correctly before using the machine.
Conclusion
Disconnecting the hour meter on a John Deere 50G excavator is a straightforward process, but it should be done with caution. Make sure to follow proper safety procedures, and always keep track of operating hours manually if the meter is disconnected. If in doubt, consulting with a professional mechanic or technician is recommended to avoid damaging the electrical system or voiding any warranties.
