Fixing Hydraulic Power Loss in John Deere Skid Steer Loaders

John Deere skid steer loaders are renowned for their power, versatility, and reliability. However, like all heavy machinery, they may encounter problems over time, with hydraulic system issues being one of the most common. In this blog, we’ll address a frequently asked question: "Why is my John Deere skid steer loader losing hydraulic power?"

By understanding the causes, diagnosing the problem, and implementing effective solutions, you can restore your loader to full working order.

Q1: Why Does a John Deere Skid Steer Loader Lose Hydraulic Power?

Hydraulic power loss in a John Deere skid steer loader can result from various factors. Below are the most common causes:

1. Low Hydraulic Fluid Levels
   • Insufficient fluid disrupts pressure, reducing power delivery.
2. Air in the Hydraulic System
   • Air bubbles in the hydraulic lines can impede fluid flow and reduce efficiency.
3. Contaminated Hydraulic Fluid
   • Dirt or debris in the fluid can block filters and affect system performance.
4. Worn Hydraulic Pump
   • A damaged pump cannot maintain adequate pressure for operation.
5. Faulty Control Valves
   • Malfunctioning valves may restrict fluid flow, reducing power output.
6. Leaks in the Hydraulic System
   • Broken seals, loose connections, or damaged hoses lead to pressure loss.

Q2: How Can I Diagnose Hydraulic Power Loss in My Skid Steer Loader?

Here’s a step-by-step guide to identify the problem:

Step 1: Check Hydraulic Fluid Levels

Inspect the reservoir and ensure the fluid level is within the manufacturer’s recommended range.

Step 2: Inspect for Leaks

Look for visible leaks around hoses, seals, and fittings. Use a pressure gauge to detect pressure drops caused by hidden leaks.

Step 3: Examine Filters

Clogged filters reduce flow and pressure. Remove and inspect them for debris or wear.

Step 4: Test the Hydraulic Pump

Use a flow meter to measure the pump’s output. Reduced flow indicates wear or internal damage.

Step 5: Assess Control Valves

Check control valves for sticking or improper operation. This might require professional diagnostic tools.

Q3: How Can I Fix Hydraulic Power Loss in My John Deere Skid Steer Loader?

Solution 1: Refill Hydraulic Fluid

• Use manufacturer-approved hydraulic fluid.
• Avoid overfilling, as it can cause system inefficiencies.

Solution 2: Bleed the Hydraulic System

• Remove air bubbles from the hydraulic lines by following the manufacturer’s bleeding procedure.

Solution 3: Replace Contaminated Fluid and Filters

• Drain old fluid and replace it with clean fluid.
• Install new hydraulic filters to maintain system cleanliness.

Solution 4: Repair or Replace Damaged Components

• Fix leaks by replacing seals, gaskets, or damaged hoses.
• Replace a worn hydraulic pump or faulty control valves with OEM parts.

Solution 5: Conduct Routine Maintenance

• Regularly inspect hoses, fittings, and filters to prevent future issues.

Q4: How Can I Prevent Hydraulic Power Loss in John Deere Skid Steer Loaders?

Preventive maintenance is crucial for avoiding downtime and costly repairs.

Follow Maintenance Schedules

Refer to the John Deere Manuals for detailed maintenance guidelines.

Use Quality Parts and Fluids

Only use John Deere-approved parts and fluids to ensure system compatibility and performance.

Daily Inspections

• Check for leaks, worn hoses, and loose connections before operating the machine.
