If the hydraulic pump is the heart of the steering system, the power steering cylinder is its muscle. A large number of Clark forklift models use power steering cylinders to give axial rotation to their rear wheels. In other words, thanks to these devices, these material-handling vehicles can quickly turn their rear wheels, whether the vehicle is carrying loads or not. Therefore, it is crucial to learn how to judge when is the right moment to replace them. With that in mind, Lift Parts Warehouse wants to share some basics about Clark forklift steering cylinder assemblies and what to do when looking for new replacements.
Clark Forklift Power Steering Cylinder Advantages
The vast majority of Clark forklift models use a power steering system, which is no coincidence. Power steering cylinders are a safe and efficient way to turn both rear wheels without much resistance. Also, unlike other steering system models, these are much less expensive to maintain.
When you turn the steering wheel, the internal rod of the cylinder moves in such a way that both rear wheels turn accordingly. And because it is activated by a hydraulic fluid and not by a transmission mechanic, the effort you have to put into it when turning the steering wheel is minimal.
How Does a Clark Forklift Power Steering Cylinder Works?
Clark forklift power steering cylinders are hydraulic cylinders that turn the vehicle's steering wheels in the desired direction and angle when the driver turns the steering wheel. Like all hydraulic cylinders, they work by Pascal's principle, which states that a change in pressure at any point in a fluid is transmitted through the fluid so that the same change occurs everywhere.
A power steering cylinder has two chambers filled with hydraulic fluid separated by a piston. When the hydraulic pressure in one chamber increases, it will push the piston in the opposite direction. When the piston moves, so do the internal rods connected to it. The end of the rod is connected to the mechanism in which the forklift wheels pivot.

Find the Steering Cylinder in Your Clark Forklift
Clark forklift power steering cylinders are located on the rear side of many Clark lift trucks. It is fixed to the steering axle of the vehicle. At the ends of the steering cylinder barrel, it will attach the hydraulic hoses from which the hydraulic steering fluid will go in and out through the inner chambers. The ends of the cylinder rods are connected to the steering linkage.
The fact of having the steering system on the rear side makes the forklift maneuverability much greater, especially in sharp spaces. This configuration allows the driver to make tighter turns when the vehicle is moving backward.
Common Clark Forklift Steering Cylinder Symptoms
Clark forklift power steering cylinders are designed and manufactured to withstand high-duty cycles in the most demanding environments. Its main components are made of cast iron and steel, so they are highly resistant. But this does not mean that they cannot be damaged. That's why they must receive maintenance from time to time to ensure their lifespan.
They are not cheap devices, so taking care of them is essential. Recognizing their main symptoms of faults in time can make the difference between a simple replacement of seals to a complete replacement of the cylinder. Below we will highlight the most common symptoms when a Clark forklift's power steering cylinder fails.
Hydraulic liquid leaks.
