Why Does My Forklift Stall When Turning the Wheels and How Can I Fix It?

Forklift stalling when turning the wheels can be caused by binding in the steering mechanism, hydraulic pressure issues, or faulty priority valves. Diagnosing the problem involves checking steering fluid levels, inspecting for mechanical binding, and ensuring hydraulic components function correctly to restore smooth operation.

What Are the Common Causes of Forklift Stalling When Turning?

Forklift stalling during wheel turns often results from:

• Binding or mechanical obstruction in the steering linkage or wheels.

• Low or contaminated steering hydraulic fluid.

• Faulty or flaky priority valves affecting hydraulic flow.

• Worn or damaged steering gears or cylinders.

• Tire misalignment causing excessive strain on the drivetrain.

Identifying the root cause is crucial for effective repair.

How Does Steering Fluid Affect Forklift Performance?

Steering fluid lubricates and powers the hydraulic steering system. Low fluid levels or thickened, contaminated fluid reduce hydraulic pressure, causing sluggish steering and engine stalling. Regularly checking and replacing steering fluid maintains proper system pressure and responsiveness.

Which Mechanical Issues Can Lead to Binding and Stalling?

Mechanical binding can occur due to:

• Debris or corrosion in steering joints.

• Excessive wear or damage to steering components.

• Improper lubrication causing increased friction.

• Misaligned or damaged tires restricting wheel movement.

Addressing these issues reduces steering resistance and prevents stalling.

Why Is the Priority Valve Important in Steering Systems?

The priority valve regulates hydraulic flow between steering and other functions. A faulty or intermittent priority valve may restrict steering fluid, causing the engine to stall when turning wheels due to increased load. Testing and replacing the valve if necessary restores proper hydraulic balance.

How Can You Diagnose Steering-Related Stalling?

• Check steering fluid level and condition; replace if dirty or low.

• Inspect steering linkage and joints for binding or damage.

• Test priority valve function with hydraulic pressure gauges.

• Observe engine behavior during wheel turns.

• Examine tire condition and alignment.

Systematic diagnosis helps pinpoint the cause.

When Should You Adjust or Replace Steering Components?

Replace or adjust steering parts if:

• Binding persists after fluid maintenance.

• Components show visible wear or damage.

• Priority valve tests fail or show erratic behavior.

• Tires are unevenly worn or misaligned.

Proper maintenance extends component life and prevents stalling.

Where Can You Find Reliable Parts and Service for Forklift Steering?

Authorized dealers and specialized suppliers provide:

• Genuine steering components and priority valves.

• Technical manuals and service guides.

• Professional repair and maintenance services.

Using quality parts ensures durability and safety.
