Common Causes for Auxiliary Hydraulic Failure
If you’re experiencing issues with the auxiliary hydraulics on your New Holland LX565, the following are common causes to investigate:
- Hydraulic Fluid Levels
- Low hydraulic fluid is one of the most straightforward causes for auxiliary hydraulic failure. If the fluid level is too low, it can cause insufficient pressure to operate the auxiliary circuits.
- Solution: Check the hydraulic fluid levels and top them up to the appropriate levels as per the machine's manual.
- Low hydraulic fluid is one of the most straightforward causes for auxiliary hydraulic failure. If the fluid level is too low, it can cause insufficient pressure to operate the auxiliary circuits.
- Clogged or Contaminated Hydraulic Filter
- A clogged hydraulic filter can restrict the flow of fluid, reducing the pressure needed to power the auxiliary hydraulics. Contaminants in the hydraulic fluid, such as dirt, debris, or water, can also cause similar problems.
- Solution: Replace the hydraulic filter if it is dirty or clogged, and consider flushing the hydraulic system to remove any contaminants.
- A clogged hydraulic filter can restrict the flow of fluid, reducing the pressure needed to power the auxiliary hydraulics. Contaminants in the hydraulic fluid, such as dirt, debris, or water, can also cause similar problems.
- Faulty Hydraulic Pump
- The hydraulic pump is responsible for generating the pressure required for both the main and auxiliary hydraulic systems. A failing pump may provide insufficient pressure, preventing the auxiliary hydraulics from functioning.
- Solution: Inspect the hydraulic pump for signs of wear or damage. If the pump is malfunctioning, it may need to be replaced or repaired.
- The hydraulic pump is responsible for generating the pressure required for both the main and auxiliary hydraulic systems. A failing pump may provide insufficient pressure, preventing the auxiliary hydraulics from functioning.
- Auxiliary Hydraulic Valve Issues
- The auxiliary hydraulic valve controls the flow of fluid to the auxiliary circuit. If the valve becomes faulty or gets stuck, the flow of fluid to the attachments may be restricted or blocked entirely.
- Solution: Test the valve to ensure it is opening and closing properly. If there is a malfunction, the valve may need to be cleaned, adjusted, or replaced.
- The auxiliary hydraulic valve controls the flow of fluid to the auxiliary circuit. If the valve becomes faulty or gets stuck, the flow of fluid to the attachments may be restricted or blocked entirely.
- Hoses and Fittings
- Leaking hoses or fittings can reduce hydraulic pressure and cause a lack of fluid flow to the auxiliary system. Even small leaks can significantly affect the performance of the hydraulics.
- Solution: Inspect all hoses and fittings for signs of wear, cracks, or leaks. Replace any damaged hoses or fittings to restore proper pressure.
- Leaking hoses or fittings can reduce hydraulic pressure and cause a lack of fluid flow to the auxiliary system. Even small leaks can significantly affect the performance of the hydraulics.
- Auxiliary Hydraulic Controls
- The control lever or switch that activates the auxiliary hydraulics could be faulty. In some cases, the wiring or electrical components controlling the hydraulics may also be at fault.
- Solution: Check the electrical connections and control lever for proper operation. If there is a wiring issue or a malfunctioning switch, repair or replace the faulty components.
- The control lever or switch that activates the auxiliary hydraulics could be faulty. In some cases, the wiring or electrical components controlling the hydraulics may also be at fault.
- Bypass Valve Issues
- Many machines are equipped with a bypass valve to protect the hydraulic system from excessive pressure. If this valve is malfunctioning or stuck, it could limit hydraulic fluid flow to the auxiliary circuit.
- Solution: Inspect the bypass valve and ensure it is functioning correctly. If it is stuck or damaged, it will need to be repaired or replaced.
