Like many excavators, the undercarriage of the CAT 325 LN can wear down over time, especially in rough, uneven terrain. The tracks, rollers, and sprockets take a lot of punishment, and failure to maintain them can lead to costly repairs.
Electrical problems in the CAT 325 LN can range from issues with the battery to wiring problems in the machine’s control system. In some cases, these malfunctions can prevent the engine from starting or cause unexpected shutdowns.
Proper maintenance is the key to maximizing the lifespan and performance of the CAT 325 LN Excavator. Regular inspections and routine maintenance tasks will not only help prevent major issues but also increase the machine's resale value.
1. Regular Oil and Filter Changes
Changing the engine oil and filters on schedule is one of the most important tasks for keeping your excavator running smoothly. Clean oil is essential for lubricating the engine and preventing internal wear.
As mentioned earlier, overheating is a common issue in excavators. To prevent this, ensure the cooling system is cleaned regularly. Clogged radiators or inefficient cooling systems can lead to engine failure.
Keeping the tracks and undercarriage components in good shape is essential for the overall health of your excavator. Perform frequent inspections and take action when you notice excessive wear or damage. Regularly greasing the undercarriage and ensuring proper tension can prevent premature failure.
Many modern CAT excavators, including the CAT 325 LN, are equipped with advanced digital control systems. Over time, software updates may be required to keep the machine’s systems running smoothly. Regular calibration of sensors and components like the bucket load sensors and GPS systems can help maintain precision and improve the overall performance of the machine.
Troubleshooting: When to Call a Professional
While many problems with the CAT 325 LN can be solved with basic knowledge and preventive maintenance, some issues require professional intervention. If you encounter persistent engine problems, hydraulic failures, or electrical malfunctions that you cannot resolve, it may be time to contact a qualified technician or CAT dealer.
The CAT 325 LN is a powerful and reliable excavator, known for its performance across a variety of applications. While common issues like hydraulic failures, overheating, and undercarriage wear may arise, these can typically be mitigated with proper maintenance and timely repairs.
For those who own or operate this iconic machine, it’s important to stay proactive about maintenance and keep an eye out for potential problems. With the right care, the CAT 325 LN Excavator can continue to perform efficiently and reliably for years to come, supporting heavy-duty operations and projects across the globe.

One of the recurring problems with the CAT 325 LN is the failure of the hydraulic system. Over time, hoses and seals can degrade, leading to leaks or loss of pressure. This can severely affect the performance of the arm, boom, and other components that rely on hydraulic power.
- Troubleshooting Tip: Regularly check for hydraulic fluid leaks, and ensure that the hydraulic system is maintained according to the manufacturer's guidelines. If you notice sluggish movements or delayed responses from the machine, it could be a sign that the hydraulic pressure is compromised.
The CAT 325 LN’s engine can overheat under heavy usage, especially in hot climates or during strenuous tasks. Overheating may be caused by clogged radiators, low coolant levels, or faulty thermostats.
- Story: One operator in Florida mentioned how their CAT 325 LN started experiencing frequent overheating issues during summer months. Upon inspection, they found the radiator clogged with debris, which was preventing proper airflow. A thorough cleaning of the radiator and replacing the coolant solved the problem.
- Preventive Measure: Regularly clean the radiator and ensure coolant levels are maintained. Check for any signs of leaks in the cooling system and replace parts that appear worn.
Like many excavators, the undercarriage of the CAT 325 LN can wear down over time, especially in rough, uneven terrain. The tracks, rollers, and sprockets take a lot of punishment, and failure to maintain them can lead to costly repairs.
- Maintenance Tip: Regularly inspect the undercarriage and check for signs of wear on the tracks. Ensure that the tracks are properly tensioned, and address any issues like misalignment or excessive wear before they worsen.
Electrical problems in the CAT 325 LN can range from issues with the battery to wiring problems in the machine’s control system. In some cases, these malfunctions can prevent the engine from starting or cause unexpected shutdowns.
- Advice: If you experience electrical failures, inspect the battery and wiring for corrosion or loose connections. Ensure the fuses are intact and functioning, and check the alternator for proper charging.
