The John Deere 310G is a popular backhoe loader in the construction industry, known for its versatility and reliability. Equipped with a mechanical front-wheel drive (MFWD) system, the 310G is designed to provide better traction on rough terrain, making it an ideal choice for both light and heavy construction tasks. However, like any complex machinery, issues can arise with the MFWD system, especially concerning its "ever-active" feature. This article delves into the potential issues with the John Deere 310G MFWD system and offers troubleshooting tips for operators.
Understanding the John Deere 310G MFWD System
The MFWD (Mechanical Front-Wheel Drive) system in the 310G is designed to automatically engage when additional traction is required. This is a key feature that helps ensure stability and performance in various operating conditions, such as when the machine is working on soft ground, uphill, or in challenging weather conditions. The “ever-active” aspect refers to the continuous engagement of the MFWD, meaning that the front wheels are engaged all the time, even when not needed.
Common Problems with the MFWD System
The John Deere 310G MFWD system plays a crucial role in providing traction and stability on challenging terrain. By understanding the common issues and following proper diagnostic and repair steps, operators can keep the MFWD system functioning optimally. Regular maintenance, timely repairs, and mindful operation will help extend the life of the backhoe loader and ensure it continues to perform reliably on the job site.

The “ever-active” aspect refers to the continuous engagement of the MFWD, meaning that the front wheels are engaged all the time, even when not needed.
Common Problems with the MFWD System
- Constant Engagement of MFWD
One of the most common issues with the John Deere 310G MFWD system is the constant engagement of the front-wheel drive. When this happens, the MFWD remains active even when the machine is on stable, hard ground where additional traction isn’t required. This can lead to unnecessary wear and tear on the system and reduced fuel efficiency.
- Traction Problems and Inconsistent Engagement
While the MFWD system is supposed to engage automatically when needed, some users report traction issues, such as the system not engaging when it should or engaging too late. This can cause difficulty when operating in challenging environments where extra traction is necessary.
- Hydraulic or Mechanical Failures
The MFWD system relies on hydraulics and mechanical components to function properly. Over time, wear and tear on components like the hydraulic pumps, valves, or transmission seals can lead to hydraulic fluid leaks or mechanical failures that affect the engagement of the MFWD.
- Electrical Issues and Sensor Malfunctions
In some cases, the issue may not lie with the mechanical or hydraulic components but with the electrical system controlling the MFWD. Faulty sensors or wiring issues can prevent the system from properly engaging or disengaging the front-wheel drive.
- Visual Inspection and Fluid Check
A common first step in diagnosing MFWD issues is performing a visual inspection. Look for signs of fluid leaks around the hydraulic system, as leaks can directly affect the engagement of the MFWD system. Also, check the hydraulic fluid levels and replace any fluids that are dirty or low.
- Testing the Engagement Mechanism
To test the MFWD system, drive the machine in various conditions, such as soft ground or uphill, and observe whether the front wheels engage when traction is needed. If the system fails to engage, it may be a sign of an issue with the hydraulic or mechanical components.
- Check the Electrical System
For electrical-related issues, inspect the wiring and sensors involved in the MFWD system. If any sensors are malfunctioning, it may prevent the system from correctly sensing when the front-wheel drive should be engaged. Use diagnostic tools to check the system’s error codes and pinpoint the issue.
- Check the System’s Solenoid and Valve
The MFWD system relies on solenoids and valves to control fluid flow to the front-wheel drive. These components can wear out or become clogged, causing the system to fail or engage improperly. Inspect the solenoid and valve for signs of damage, corrosion, or blockage, and replace any faulty parts.
- Repairing Hydraulic Leaks
If the MFWD system is affected by hydraulic leaks, the first step is to replace any damaged hoses or seals. Ensure that all connections are tight, and the hydraulic fluid is filled to the proper level. After repairs, test the system to ensure that the hydraulic pressure is sufficient for proper MFWD engagement.
- Replacing Worn-Out Components
Worn or damaged components, such as the hydraulic pump, valves, or the MFWD clutch, should be replaced as necessary. Regular maintenance of these components can prevent them from causing significant issues with the front-wheel drive system. Always use OEM parts for replacements to ensure compatibility and performance.
- Correcting Electrical Problems
If the issue lies with the electrical system, inspect the sensors and wiring for any signs of wear or malfunction. Repair or replace any damaged wires, connectors, or sensors. Once the electrical system is working correctly, the MFWD should engage properly when needed.
- Regular Fluid Checks
To avoid issues with the MFWD system, it is essential to regularly check the hydraulic fluid levels and replace the fluid as per the manufacturer’s recommended intervals. Using clean, high-quality hydraulic fluid can prevent blockages and contamination in the system.
- Frequent Component Inspections
Periodically inspect the hydraulic hoses, solenoids, valves, and other MFWD components for signs of wear or damage. Catching small issues early can prevent major breakdowns and reduce repair costs in the future.
- Electrical System Maintenance
Keep the electrical components, such as the sensors and wiring, clean and well-maintained. Inspect them during routine checks to avoid malfunctioning or disconnecting. This ensures the MFWD system remains responsive when needed.
- Keep the MFWD Disengaged When Not in Use
To reduce wear and tear on the MFWD system, disengage the system when it is not needed, especially when operating on hard, flat ground. This can help improve fuel efficiency and extend the life of the components.
