Troubleshooting Power Steering Pump Failure in Battle Motors ICE Units

The power steering pump is gear-driven off the back of the air compressor, and one of the main causes of failure is pump cavitation due to the location of the power steering fluid reservoir. A relocation kit is available to address this issue.

Symptoms: 

• Steering Difficulty: Increased effort required to turn the steering wheel, especially at low speeds. 

• Noise: Whining, cavitation, or grinding noises coming from the power steering pump, particularly when turning the wheel. 

• Vibration or Jerking: The steering wheel may vibrate or jerk due to inconsistent hydraulic pressure from the pump. 

• Fluid Leaks: Leaking power steering fluid around the pump or lines. 

• Overheating: The power steering system may overheat if cavitation occurs regularly.

Possible Causes: 

1. Pump Cavitation: Due to the location of the power steering reservoir, the pump can cavitate, leading to premature wear and reduced efficiency. 
2. Fluid Leaks: Leaks in the power steering system can lead to low fluid levels and insufficient pressure. 
3. Power Steering Line Issues: Cracked or worn lines can impede fluid flow, causing the pump to overwork and fail. 
4. Gear-Driven Pump Wear: The gear-driven power steering pump can wear over time, especially if subjected to cavitation or poor maintenance. 

Troubleshooting Steps: 

1. Inspect the Power Steering Pump for Cavitation: 
   1. Listen for signs of cavitation, such as whining or air bubbles in the fluid. 
   2. If cavitation is suspected, install the power steering reservoir relocation kit to reduce cavitation and extend the life of the pump. 
2. Check Power Steering Fluid Levels: 
   1. Inspect the power steering fluid reservoir for low levels. Top off the fluid if necessary with the recommended type. 
   2. If fluid levels are consistently low, check for leaks in the lines or around the pump. 
3. Inspect Power Steering Lines: 
   1. Examine the power steering lines for wear, cracks, or leaks. Replace any damaged lines to ensure proper fluid flow to the pump. 
4. Check for Gear Pump Wear: 
   1. Inspect the gear-driven power steering pump for signs of wear or internal damage. If the pump is showing signs of failure, it may need to be replaced. 
5. Install the Relocation Kit: 
   1. Consider installing the power steering reservoir relocation kit if frequent cavitation is detected. This kit helps reposition the reservoir to improve fluid flow and reduce cavitation, extending the pump’s lifespan. 

Resolution: 

Addressing pump cavitation through the installation of the relocation kit, along with repairing any fluid leaks or line damage, should resolve power steering pump issues. After repairs, test the vehicle's steering to ensure smooth operation. 

Preventive Measures: 

• Reservoir Relocation: Install the power steering reservoir relocation kit on affected units to prevent cavitation and prolong the life of the pump. 

• Regular Inspections: Check the power steering fluid levels and lines for signs of wear, damage, or leaks during routine maintenance. 

• Pump Health Monitoring: Listen for signs of cavitation and address them promptly to avoid pump damage.
