Common Problems with JD 755A Track Loader
The JD 755A is designed to handle a wide range of tasks, from digging and lifting to pushing and grading. Despite its robust construction, a few common issues can arise, particularly as the machine ages or is exposed to harsh conditions.
- Hydraulic System Issues
One of the most frequently reported issues with the JD 755A is related to its hydraulic system. Hydraulic systems in track loaders can be prone to leaks, pump failures, or low fluid levels. These issues can result in poor performance, including slower lift speeds or failure to engage certain functions.
Solution: Regularly check for hydraulic fluid leaks, and replace seals or hoses as needed. Ensure that the hydraulic fluid is at the proper level and that the fluid is of the recommended type. If pump failure is suspected, the hydraulic pump may need to be replaced.
- Track Wear and Tear
Another common issue with track loaders is the wear and tear on the tracks. Tracks on a JD 755A can wear out over time due to prolonged exposure to rough terrain, improper tensioning, or failure to lubricate moving parts.
Solution: Inspect the tracks regularly for signs of wear, such as cracks or flat spots. Track tension should be checked periodically and adjusted according to the manufacturer’s specifications. If the tracks are damaged beyond repair, they may need to be replaced.
- Engine Performance Problems
As with any diesel-powered equipment, the JD 755A may experience engine performance issues. These problems can be caused by fuel delivery issues, clogged air filters, or problems with the engine's internal components. Symptoms might include rough idling, loss of power, or difficulty starting.
Solution: Regularly replace the air filter and ensure the fuel system is clean. If the engine is sluggish, check the fuel injectors and fuel lines for clogs or leaks. A full engine inspection may be needed if internal engine components are suspected to be damaged.
- Electrical Problems
Electrical issues can also occur with the JD 755A, especially as the equipment ages. Faulty wiring, worn-out fuses, or issues with the battery can prevent the loader from starting or cause intermittent power loss during operation.
Solution: Inspect all electrical connections for corrosion or loose wires. Clean the battery terminals and check the battery’s charge. If electrical components such as relays or the alternator are malfunctioning, they may need to be replaced.
Maintaining your JD 755A Track Loader is essential to keeping it in good working condition. Routine maintenance can prevent many common issues and extend the life of the machine. Here are some essential maintenance tips:
- Regular Oil and Filter Changes
Just like any other diesel engine, the JD 755A requires regular oil and filter changes to ensure optimal engine performance. Following the manufacturer’s recommended intervals for oil changes will help prevent engine damage and reduce the risk of costly repairs.
- Hydraulic Fluid Checks
Regularly checking and replacing the hydraulic fluid is essential to maintaining the loader’s hydraulic performance. Low fluid levels can result in decreased lifting capacity, while dirty fluid can cause pump wear and system inefficiencies.
- Track Inspection and Tensioning
Regular track inspections are critical for ensuring safe and efficient operation. Check for wear and adjust the track tension as needed. Tracks that are too loose or too tight can lead to premature wear, decreased traction, and unnecessary strain on the drivetrain.
- Cooling System Maintenance
Keep an eye on the cooling system, including the radiator and coolant levels. Overheating can cause significant damage to the engine, leading to performance issues. Ensure that the cooling system is free from debris and that the coolant is replaced as per the maintenance schedule.
- Keep the Loader Clean
Dirt and debris can accumulate on and under the machine, which can lead to overheating, clogged filters, or damaged components. Regularly cleaning the loader, especially the undercarriage, will help maintain optimal performance and prevent build-up that could cause operational issues.
One of the most common complaints about the JD 755A Track Loader is difficulty starting the engine. When the engine won’t start, it’s important to systematically troubleshoot the issue.
- Check the Battery:
A dead or weak battery is often the cause of engine starting issues. If the battery is more than a few years old, it may need to be replaced. Make sure the battery terminals are clean and free of corrosion, which can prevent the flow of electricity.
- Fuel System Check:
If the engine cranks but doesn’t start, the problem could be with the fuel system. Check for fuel blockages, fuel filter issues, or air in the fuel lines. Clogged fuel filters can restrict fuel flow, causing the engine to fail to start.
- Starter and Solenoid:
If the engine does not turn over at all, the problem could lie with the starter or solenoid. A faulty starter can fail to engage the flywheel, while a bad solenoid can prevent electrical current from reaching the starter.
- Glow Plug Issues (Cold Starts):
Diesel engines, including the JD 755A, rely on glow plugs to help start the engine in cold conditions. If the glow plugs are faulty, the engine may have trouble starting in cold weather. Replacing the glow plugs is a relatively simple fix that can improve cold-start reliability.
Despite some common mechanical challenges, the John Deere 755A Track Loader remains a highly valuable piece of machinery for construction, landscaping, and farming. Known for its stability, ease of operation, and powerful performance, it continues to be a go-to option for professionals who need a reliable compact loader.
John Deere’s reputation for durable, long-lasting machinery also adds to the value of the 755A. The company has invested in creating equipment that can withstand the rigors of tough work environments, making it a great choice for owners looking to invest in quality equipment.
