Mustang 2070 No Hydraulics Issue Troubleshooting and Solutions - MikePhua - 07-04-2025
The Mustang 2070 skid steer experiencing no hydraulics after starting, or the machine starting and then dying, is often linked to hydraulic system malfunctions or electrical issues. This problem typically arises from issues with the hydraulic pump, fluid, or control systems. Below are the common causes and solutions to help resolve the hydraulic failure on the Mustang 2070.
Problem Description
Users report that the Mustang 2070 skid steer starts up, but after a few seconds, it dies, and the hydraulic system does not work. The loss of hydraulic function may be caused by a faulty hydraulic pump, hydraulic fluid issues, or electrical system malfunctions. These problems prevent the machine from performing hydraulic-dependent tasks such as lifting and digging.
Common Causes and Solutions
- Check Hydraulic Fluid Condition
Hydraulic fluid quality and levels are critical for proper hydraulic system operation. Start by checking the hydraulic fluid level to ensure it is adequate. If the fluid is low, top it up to the normal level. If the hydraulic fluid is contaminated or degraded, it should be replaced, and the hydraulic system should be cleaned. Contaminants in the fluid can damage the hydraulic pump and other components.
- Inspect the Hydraulic Pump
A malfunctioning hydraulic pump can prevent the hydraulic system from working correctly. Check if the hydraulic pump is operating properly and providing sufficient pressure. If the pump is not working as it should or is damaged, it will need to be repaired or replaced.
- Inspect the Electrical System and Sensors
Electrical system malfunctions can prevent the hydraulic system from functioning. Check the sensors and control modules in the electrical system to ensure all connections are secure and there are no loose or damaged wires. Electrical issues may trigger the hydraulic system's safety mechanisms, preventing it from working. If there is an electrical fault, the sensors may need to be recalibrated or replaced.
- Check the Hydraulic Valves
Faulty hydraulic valves can also cause issues with hydraulic fluid flow, leading to hydraulic system failure. Inspect all hydraulic valves to ensure they are not stuck, damaged, or blocked. If any valves are malfunctioning, they should be repaired or replaced.
- Check Battery Voltage
Low battery voltage can affect the operation of the electrical control system, causing the hydraulic system to fail to start. Inspect the battery’s voltage and connection to ensure it is adequately charged and properly connected. If the battery is low or there is a poor connection, it may hinder the hydraulic system's startup.
The lack of hydraulic function in the Mustang 2070 skid steer is typically related to hydraulic fluid issues, a faulty hydraulic pump, electrical system failures, or valve problems. By checking the hydraulic fluid, pump, valves, and electrical system, most issues can be resolved. If the problem persists after troubleshooting, it is recommended to contact Panswork’s professional repair service for a detailed inspection and repair to restore normal machine operation.
