When the New Holland LS170 skid steer stalls under load, it usually indicates an issue with the power transmission, fuel supply, or engine control systems. Here are the key steps to troubleshoot and resolve the issue:
1. Check the Fuel System
Fuel issues are a common cause of stalling under load. Start by inspecting the fuel filter to see if it’s clogged. A blocked fuel filter can restrict fuel flow, causing the engine to stall. Additionally, check the fuel pump and injectors to ensure they are functioning properly and providing stable fuel pressure.
2. Inspect the Air Filter
A clogged or dirty air filter can prevent the engine from receiving enough air, which affects combustion efficiency. Under load, restricted airflow can lead to engine stalling. Check the air filter and replace it if necessary to ensure proper airflow.
3. Examine the Engine Sensors
Faulty engine sensors, such as the air pressure sensor, temperature sensor, or fuel pressure sensor, can also lead to stalling. Inspect these sensors to ensure they are working correctly and providing accurate readings. If any sensors are faulty, they may need to be replaced or repaired.
4. Inspect the Electrical System and Grounding
Electrical system issues, such as low battery voltage or poor grounding, can cause the engine to stall. Check the battery voltage to ensure it is within the normal range. If the voltage is too low, the electrical system may not function properly, affecting engine operation. Additionally, verify that all ground connections are secure.
5. Check the Cooling System
Engine overheating is another common cause of stalling. Inspect the cooling system, including coolant levels, radiator, and water pump, to ensure they are functioning properly. A malfunctioning cooling system could cause the engine to overheat and stall to prevent damage.
6. Check the Transmission and Drivetrain
Issues with the transmission or drivetrain can also lead to stalling under load. Inspect the transmission fluid level and quality. Low or degraded fluid can affect the transmission’s performance and cause the engine to stall when under load.
Conclusion
When the New Holland LS170 stalls under load, start by checking the fuel system, air filter, and engine sensors. If these components are functioning correctly, move on to inspecting the electrical system, cooling system, and transmission. By systematically troubleshooting, you can identify and resolve the issue, restoring the machine to proper operation.
