Over time, engines in Poclain excavators can experience issues due to wear and tear, fuel system problems, or poor maintenance. Some common engine issues include:
Poclain machines, especially the older models, can experience issues with the transmission or gearbox, which is another common area for failure. Some typical symptoms include:
4. Under-Carriage and Structural Wear
Given the intense wear and tear that comes from constant movement on construction sites, the undercarriage of Poclain machines can often face significant damage. Some issues to look out for include:
Maintenance Tips for Poclain Excavators
Proper maintenance is key to ensuring the longevity of your Poclain machine. Regular service and timely repairs can prevent the majority of common problems that these machines face. Below are some important maintenance tips:
1. Regular Hydraulic Maintenance
Regularly check the hydraulic fluid levels and inspect the filters and seals for wear. Flushing the hydraulic system and using the proper hydraulic fluid for your Poclain machine can extend the life of the system. If you are experiencing loss of hydraulic pressure, don't hesitate to check for leaks or air in the system.
2. Engine Care and Maintenance
Ensure that the engine oil is changed according to the manufacturer’s recommended schedule, and inspect fuel filters and the cooling system regularly. Overheating or fuel-related issues can often be avoided with good maintenance practices. Also, check the condition of the alternator, battery, and electrical systems to prevent starting issues.
3. Transmission and Gearbox
Keep an eye on the transmission fluid levels and ensure that any leaks are addressed promptly. Listen for unusual sounds from the gearbox or transmission, which could signal internal damage. Regular fluid changes and inspections will go a long way in preventing costly repairs.
4. Track and Undercarriage Maintenance
Inspect the tracks, sprockets, rollers, and idlers regularly. Ensure the track tension is within the optimal range and check for signs of damage. Proper lubrication of the rollers and sprockets can help prolong their life and improve the efficiency of the machine.
Poclain Machines Today
Although Poclain is no longer producing new machines under its original brand, many of its excavators and equipment are still in use today. The legacy of Poclain’s durable and powerful machines lives on through operators who have kept these machines running for decades. With proper maintenance and care, Poclain machines can continue to serve their owners for many years, offering reliability and power on construction sites worldwide.
Conclusion: Keeping Your Poclain Machine Running Smoothly
While Poclain machines may not be as ubiquitous today as they were in the past, they remain an important part of the construction and demolition landscape. By understanding the common issues they face and performing regular maintenance, operators can keep their Poclain machines in good working order. From hydraulic problems to engine issues, the key to longevity lies in attention to detail and proactive service.
The Poclain legacy is marked by durability and engineering excellence, and with the right care, these machines will continue to perform at their best for years to come. Whether you're troubleshooting common issues or performing regular maintenance, keeping a Poclain excavator in top shape requires a blend of knowledge, vigilance, and dedication.

Common Issues with Poclain Excavators
Like any heavy machinery, Poclain excavators can experience a range of issues during their lifecycle. Whether it's hydraulic problems, engine issues, or mechanical wear, here are some of the most common problems that Poclain owners might encounter:
1. Hydraulic System Failures
One of the most common issues reported with Poclain machines is problems with the hydraulic system. These systems are complex and involve multiple components, including pumps, hoses, and valves, which are all susceptible to wear over time.
- Hydraulic leaks are a frequent issue, often caused by worn seals or hose damage. If you notice a drop in pressure or the machine struggling to lift or dig, it's essential to inspect the hydraulic hoses and check for leaks.
- Another potential problem is hydraulic fluid contamination, which can cause damage to the pump or motor if not addressed. This issue often arises from improperly maintained filters or using incorrect fluid.
- Poor performance in the boom or arm hydraulics could be a sign of pump failure or air in the system. Flushing the hydraulic system and replacing the filters may help alleviate this issue.
Over time, engines in Poclain excavators can experience issues due to wear and tear, fuel system problems, or poor maintenance. Some common engine issues include:
- Starting difficulties: If your Poclain machine has trouble starting, it could be due to fuel delivery issues, a faulty starter motor, or weak batteries. Always ensure that the fuel lines and filters are clean and the battery is in good condition.
- Engine overheating: This issue can stem from a blocked radiator or malfunctioning cooling fan. Overheating can cause serious damage to the engine, so it's crucial to address this promptly by cleaning the radiator or inspecting the fan for wear.
- Low power or stalling: If the machine is losing power or stalling under load, it could be an issue with the fuel injection system or a clogged air filter. Checking the fuel injectors and air filters should be one of the first steps in troubleshooting.
Poclain machines, especially the older models, can experience issues with the transmission or gearbox, which is another common area for failure. Some typical symptoms include:
- Difficulty shifting gears or slipping gears during operation may indicate wear in the transmission components, such as the clutch or shift linkages.
- Loss of motion or a machine that won’t move forward or backward could point to internal damage in the hydraulic drive system or transmission pump failure.
4. Under-Carriage and Structural Wear
Given the intense wear and tear that comes from constant movement on construction sites, the undercarriage of Poclain machines can often face significant damage. Some issues to look out for include:
- Worn-out tracks or track tension problems that can affect the machine’s performance. These should be checked regularly to avoid uneven wear and unnecessary strain on the drive system.
- Broken sprockets or worn-out rollers are other common structural issues that can reduce the overall efficiency of the machine.
