Troubleshooting the Gehl 5625SX: Common Issues and Solutions

[MikePhua]

The Gehl 5625SX skid steer loader is known for its versatility and power, making it a popular choice in construction and agricultural applications. However, like any heavy equipment, it can experience technical issues over time. Understanding these common problems and how to troubleshoot them is essential for keeping the machine running efficiently. This article delves into the potential problems with the Gehl 5625SX, sharing real-world troubleshooting tips and offering insights based on user experiences.
Hydraulic System Issues in the Gehl 5625SX
One of the most commonly reported issues with the Gehl 5625SX involves its hydraulic system. Hydraulic problems can manifest in several ways, including a loss of lifting power, slow bucket operation, or failure to raise the arms. The machine’s auxiliary hydraulics are critical for many attachments, so a malfunctioning system can lead to significant downtime.
Potential Causes

• Low hydraulic fluid levels: Check the fluid levels regularly, as low fluid can cause erratic operation and reduced power.
  
• Clogged filters: Dirty or clogged filters can restrict fluid flow, causing slow or jerky movements.
  
• Damaged hydraulic hoses: Leaks or wear on hydraulic hoses can lead to a loss of pressure, affecting performance.
  
• Faulty hydraulic pumps or valves: A pump or valve failure can severely hinder hydraulic function, requiring replacement or repair.
  

Real-World Example: One Gehl 5625SX user reported that their machine was experiencing slow bucket movements and struggled to lift heavy loads. After inspecting the hydraulic system, they found that a hydraulic hose had a small leak, causing a pressure drop. Once replaced, the machine operated normally.
Engine Performance and Starting Issues
Engine-related issues in the Gehl 5625SX can range from difficulty starting to complete engine failure. If the engine is turning over but not starting, the problem may lie with the fuel system, battery, or electrical connections.
Possible Causes

• Weak or dead battery: A common cause of starting issues is a weak or discharged battery. Ensure the battery is charged and connections are clean and secure.
  
• Fuel delivery problems: Blockages in the fuel line or a failing fuel pump can prevent the engine from receiving adequate fuel.
  
• Air filter clogging: A clogged air filter can restrict airflow to the engine, leading to poor performance or starting failure.
  
• Faulty glow plugs or starter motor: For cold weather starts, glow plugs help heat the engine, and if they fail, it can prevent the engine from firing up.
  

Example: A fleet manager recalled an issue with a Gehl 5625SX that wouldn’t start after a cold night. The problem was traced back to a failed glow plug, which was replaced to restore starting functionality. It’s a good practice to check the glow plugs regularly, especially in colder climates.
Drive System Malfunctions
The drive system of the Gehl 5625SX is another area where users often encounter issues. Problems such as slow or erratic movement of the skid steer can significantly impact productivity. These issues may be related to the drive motor, transmission, or wheel drive.
Troubleshooting Steps

• Check fluid levels: Low or contaminated transmission fluid can cause sluggish movement. Always ensure the correct fluid type and level.
  
• Inspect the drive motor: Worn-out motor components can lead to a loss of power. Check the motor for any signs of wear or leaks.
  
• Test the transmission: Slipping gears or unresponsiveness when shifting could indicate transmission problems. It’s important to regularly maintain the transmission and change fluid according to the manufacturer's recommendations.
  
• Examine the wheel drive system: A damaged wheel or axle can lead to uneven movement, especially if one side of the machine moves faster than the other.
  

Anecdote: A service technician shared a story where a Gehl 5625SX had irregular movements. After ruling out the hydraulics and battery, the problem was traced to the transmission fluid, which had become too contaminated. A fluid change solved the issue and restored smooth operation.
Electrical and Sensor Issues
Electrical problems can cause a variety of symptoms, from warning lights staying on to equipment failure during operation. The Gehl 5625SX features a number of sensors and electrical components that must work in harmony for the machine to function correctly.
Possible Problems

• Blown fuses: A blown fuse can cause non-functioning lights, gauges, or other electrical components. Regularly check the fuse panel for any faulty fuses.
  
• Faulty alternator: If the alternator is not charging the battery properly, it can lead to a loss of electrical power during operation.
  
• Malfunctioning sensors: Sensors, especially those for engine temperature, hydraulic pressure, and fuel levels, can fail and cause warning lights to appear or inaccurate readings.
  
• Wiring issues: Loose or corroded wiring can lead to intermittent issues with electrical components.
  

Story from the Field: A customer experienced persistent warning lights on their Gehl 5625SX, which remained on despite there being no apparent issues with the machine. After running diagnostics, the technician found a loose wiring connection in the electrical harness, which was causing the sensors to malfunction.
Routine Maintenance for Longevity
The best way to prevent many of the issues mentioned above is through routine maintenance. The Gehl 5625SX requires regular checks and servicing to ensure that its hydraulic, electrical, and engine systems function properly.
Maintenance Checklist

• Hydraulic fluid: Regularly check fluid levels and replace filters every 500 hours of operation.
  
• Engine oil: Change engine oil and filters according to the recommended schedule, typically every 250-500 hours.
  
• Air filters: Inspect and replace air filters to ensure proper engine air intake.
  
• Battery: Check battery voltage and clean terminals regularly to prevent electrical issues.
  
• Tire or track condition: Inspect the tires or tracks for damage or wear, ensuring they are properly inflated or tensioned.
  

Tip: A contractor in California shared their experience of keeping a Gehl 5625SX in top condition by sticking to a preventive maintenance schedule, resulting in minimal downtime and fewer mechanical failures over the years.
Conclusion
The Gehl 5625SX skid steer loader is a robust machine, but like all heavy equipment, it requires attention and maintenance to perform at its best. Hydraulic system issues, engine performance problems, and drive system malfunctions are some of the most common concerns, but these can often be resolved through regular maintenance and proper troubleshooting.
By keeping an eye on fluid levels, ensuring electrical components are functioning properly, and following manufacturer-recommended maintenance schedules, owners and operators can extend the lifespan of their equipment and reduce unexpected breakdowns.
Through shared experiences, it’s clear that a proactive approach to equipment maintenance will go a long way in preventing common problems, ultimately saving time and money on repairs. Whether you're working with a Gehl 5625SX on a construction site, farm, or landscaping project, staying ahead of potential issues will help keep the machine running smoothly for years to come.
