Why Is My Skid Steer Loader Not Lifting Properly? Common Causes and Solutions

A skid steer loader that’s struggling to lift properly can cause delays and affect your productivity on the job site. Whether it’s not reaching full lift capacity or struggling to lift even light loads, understanding the root causes can help you quickly address the issue and get your machine back in action.

At Manualskart.com, we provide in-depth service manuals that can guide you through troubleshooting and fixing problems like these. In this blog, we’ll cover some of the most common reasons why your skid steer loader isn’t lifting properly and how to fix them.

1. Hydraulic System Issues

Symptoms: Slow or weak lifting, or the loader won’t lift at all.

Possible Causes:

• Low hydraulic fluid levels – If the hydraulic fluid is low, the system can’t generate enough pressure to lift properly.
• Air in the hydraulic system – Air trapped in the hydraulic lines can cause erratic lifting or loss of lifting power.
• Hydraulic fluid contamination – Dirty or contaminated fluid can block the flow and reduce lifting performance.

Solution:

• Check Hydraulic Fluid Levels: Inspect the hydraulic fluid reservoir and top it off if the fluid is low. Ensure you use the correct fluid type as specified in your loader’s manual.
• Bleed the Hydraulic System: If you suspect air is trapped in the system, bleed the hydraulic lines to remove any air pockets.
• Replace Contaminated Fluid: If the hydraulic fluid looks dirty or contaminated, drain it and replace it with fresh fluid to prevent blockages and ensure smooth system operation.

2. Faulty Lift Cylinder

Symptoms: The loader struggles to lift loads, or there is visible hydraulic leakage around the lift cylinder.

Possible Causes:

• Worn-out lift cylinder seals – Worn seals can lead to hydraulic fluid leakage, reducing the lifting force.
• Damaged lift cylinder – Any damage to the cylinder can cause a loss in lifting power.

Solution:

• Inspect the Lift Cylinder Seals: Check the lift cylinder for any visible leaks. If you notice hydraulic fluid leaking around the seals, they may need to be replaced.
• Test the Lift Cylinder: If the cylinder is damaged or the seals are worn beyond repair, you may need to replace the entire lift cylinder to restore full lifting capacity.

3. Blocked or Damaged Hydraulic Hoses

Symptoms: Reduced lifting power or no lifting at all, with the loader making abnormal noises.

Possible Causes:

• Collapsed hydraulic hose – A collapsed or kinked hydraulic hose can restrict the flow of hydraulic fluid, affecting lift performance.
• Leaks in hydraulic hoses – Leaking hoses can cause a loss of hydraulic pressure, leading to slow or weak lifting.

Solution:

• Inspect the Hydraulic Hoses: Look for any visible signs of damage, wear, or leaks in the hydraulic hoses. Replace any hoses that are cracked or damaged.
• Clear Blockages: If you notice any blockages in the hoses, clear them to restore full fluid flow to the system.

4. Faulty Hydraulic Pump

Symptoms: Weak lifting, slow bucket movement, or the loader struggles to operate at full capacity.

Possible Causes:

• Worn hydraulic pump – A failing or worn hydraulic pump can cause insufficient fluid pressure, affecting lifting power.
• Pump cavitation – If the pump is not drawing in enough fluid, cavitation can occur, leading to poor system performance.

Solution:

• Test the Hydraulic Pump: If the lift system is underperforming, test the hydraulic pump’s pressure output. If it’s not delivering the correct pressure, the pump may need to be replaced.
• Check for Cavitation: Ensure the hydraulic fluid is at the proper level and that the intake lines are not blocked to avoid cavitation.

5. Damaged or Misadjusted Lift Arms

Symptoms: Uneven lifting or the loader can’t lift its full rated load.

Possible Causes:

• Bent or misaligned lift arms – If the lift arms are bent or misaligned, they won’t be able to support the proper weight or move smoothly.
• Improper lift arm adjustments – If the lift arms aren’t adjusted correctly, they may not raise or lower properly.

Solution:

• Inspect Lift Arms for Damage: Check the lift arms for any visible bends, cracks, or damage. If damaged, the arms will need to be replaced.
• Adjust Lift Arms: If the lift arms are out of alignment, they may need to be adjusted to ensure proper lifting.

6. Engine or Power Issues

Symptoms: The skid steer loader lifts poorly, especially under heavy loads or when the engine is under strain.

Possible Causes:

• Engine power loss – If the engine isn’t delivering enough power, the hydraulic system will also suffer, leading to weak lifting.
• Dirty fuel filters – Clogged fuel filters can prevent the engine from getting the fuel it needs to run optimally.

Solution:

• Check Engine Power: Perform an engine diagnostic to check for any performance issues. If the engine is weak or running poorly, perform necessary repairs or replace components.
• Replace Fuel Filters: Ensure the fuel filters are clean and replace them if they’re clogged or dirty.
