Bobcat Skid Steer Hydraulic Power Loss: Causes and Fixes

Losing hydraulic power in a Bobcat skid steer can bring operations to a halt, affecting your productivity. Hydraulic power loss can be attributed to various issues, ranging from low fluid levels to component failure. Here's a detailed guide to identifying and fixing the common causes of hydraulic power loss in Bobcat skid steers.

Low Hydraulic Fluid Levels

Symptoms:

Slow or weak hydraulic responses.

Increased noise from the hydraulic system.

Causes:

Insufficient fluid due to leaks or inadequate maintenance.

Incorrect hydraulic fluid type.

Solution:

Check hydraulic fluid levels: Ensure that the hydraulic fluid is at the proper level according to the manufacturer’s specifications.

Inspect for leaks: Look for leaks around hoses, fittings, and the reservoir.

Refill with the correct fluid: Always use the recommended hydraulic fluid to prevent compatibility issues.

Clogged Hydraulic Filters

Symptoms:

Reduced hydraulic efficiency.

Overheating and increased pressure in the system.

Causes:

Blocked filters due to dirt and debris accumulation.

Skipped filter maintenance.

Solution:

Inspect and clean the hydraulic filters: Check for dirt and debris and clean the filters thoroughly.

Replace worn-out filters: If the filters are heavily clogged or damaged, replace them with new ones.

Refer to the Case Construction Manuals for filter maintenance instructions.

Air in the Hydraulic System

Symptoms:

Erratic hydraulic behavior.

Spongy feel when operating controls.

Causes:

Air entering the system through leaks or improper sealing.

Low hydraulic fluid causing aeration.

Solution:

Bleed the hydraulic system: Use the proper procedure to remove air from the hydraulic lines.

Inspect seals and connections: Ensure that all seals and connections are tight to prevent air ingress.

Hydraulic Pump Issues

Symptoms:

Hydraulic system operates slowly or fails altogether.

Unusual noises from the pump area.

Causes:

Wear and tear on the hydraulic pump.

Contaminants causing damage to pump components.

Solution:

Inspect the hydraulic pump: Look for signs of wear, damage, or leaks.

Repair or replace the pump: Depending on the condition, either repair or replace the pump.

Dirty or Contaminated Hydraulic Fluid

Symptoms:

Slow hydraulic response.

Noisy operation and component wear.

Causes:

Dirt, water, or other contaminants in the hydraulic fluid.

Failure to change the fluid regularly.

Solution:

Flush the hydraulic system: Remove the old, contaminated fluid and flush the system.

Refill with clean, recommended fluid: Always use the correct fluid type for optimal performance.

Refer to the Kubota Equipment Manuals for detailed fluid maintenance procedures.

Hydraulic Cylinder Problems

Symptoms:

Leaking hydraulic fluid from cylinders.

Jerky or slow cylinder movements.

Causes:

Worn or damaged cylinder seals.

Buildup of debris within the cylinders.

Solution:

Inspect the hydraulic cylinders: Look for visible signs of leaks or damage.

Replace or repair seals: Replace damaged seals and clean out any debris from the cylinders.
