Power Steering Cylinder Review: Extends to 23 Inches in Open Length

Where the Power Steering Cylinder Fits

Power Steering Cylinder moves the steering linkage with a 16-1/4″ closed length for owners of Case 480B 580D Power Steering Ram systems.

Operating a backhoe with a smooth, responsive steering feel depends on a cylinder that can handle the specific pressures of the hydraulic system. A reliable steering ram allows for precise positioning of the bucket when working in confined areas.

The Power Steering Cylinder achieves this reliability through its compatibility with 2 Wheel Drive Machines and its specific fit for Case 480D and 580E models. It replaces several common part numbers, including 234447A1 and D84800.

We evaluated 11 steering cylinders and chose this one for a full review because it is one of the most-rated products that pass screening, with 26 buyer ratings. Our full review is based on a comparison of listing data and specifications. This review is for owners of Case 480B through 586E backhoe loaders.

The Short Answer on the Power Steering Cylinder

Best for: you need a replacement cylinder for a Case Backhoe Loader 480 series or 580 series and require a 16-1/4″ closed length.

The Power Steering Cylinder is a practical choice at the $152.35 price point.

• Pro: It provides an open length of 23″ for steering range.
• Pro: The steel and plastic construction includes hardware for installation.
• Con: The 4.4 rating from 26 buyers is a thin sample size for long-term reliability.
• Con: It is only compatible with 2 Wheel Drive machines, ruling out 4WD configurations.

Don’t buy this if: your machine requires a cylinder with a stroke length or mounting configuration different from the 16-1/4″ closed length spec.

Price assessment: The $152.35 price is fair for a steel-bodied cylinder that fits a wide range of Case backhoe models.

The Specifications That Matter

The open length of 23″ measures the distance the piston head travels from the fully retracted position to the fully extended position.

Before You Buy: Steering Cylinder Checklist

The first thing to check is the specific model and serial number of your machine to ensure the cylinder matches your steering configuration.

• ☐ Confirm your machine model is a Case Backhoe Loader 480B, 580B, 584C, 585C, or 586C series — an incorrect model selection results in a cylinder that cannot mount to the frame.
• ☐ Verify the stroke length requirement for your steering lock — a cylinder with a stroke length other than the 23″ open length may prevent full steering lock or cause mechanical interference.
• ☐ Check if your older B series machine requires a power steering hose adaptation — some earlier B series models will not fit without this specific modification.
• ☐ Match your pump’s output to the bore pressure rating — using a cylinder with a lower rating than your pump’s output causes seal blowout or structural failure.
• ☐ Verify compatibility with specific models like the 580SD and 586E — these high-use models are supported by this unit’s specifications.
• ☐ Measure the mounting distance to ensure it accommodates a 16-1/4″ closed length — a mismatch in length prevents the cylinder from aligning with the steering linkage.

You should not buy this product if your machine requires a cylinder with a different bore diameter or if your specific year of machine does not support the hose adaptation listed in the specifications.

Performance: What the Specs Deliver

How steel and plastic components manage hydraulic forces in this cylinder

The Power Steering Cylinder uses a combination of steel and plastic components to manage hydraulic forces. Steel provides the structural rigidity needed to withstand high-pressure cycles, while the plastic components often serve as seals or housings that reduce weight and friction within the assembly.

Using a multi-material build means the Power Steering Cylinder is designed to balance durability with weight. While the steel handles the primary mechanical stress of steering, the plastic elements allow for specific fittings and internal components that are easier to maintain or replace than solid metal parts.

Extended 23 Inch Open Length

The Power Steering Cylinder features an open length of 23 inches, which defines the total reach of the unit when fully extended. This measurement allows you to confirm the cylinder provides enough stroke to move the steering linkage through its full range of motion without hitting mechanical stops.

A 23-inch open length means you can achieve a wide steering angle on larger machines like the Case Backhoe Loader 586E. Because this length specifically dictates the reach of the piston, you must ensure your mounting points allow for this 23-inch extension to clear the frame and other components during operation.

How the Power Steering Cylinder Compares to Other Steering Cylinders

The Power Steering Cylinder offers a 16-1/4″ closed length and a 23″ open length, providing the specific stroke distance required for Case backhoe loaders.

How it compares to similar steering cylinders

The Power Steering Cylinder is the 2nd cheapest option among the six models evaluated, priced at $152.35.

From Delivery to First Use with This Steering Cylinder

Requirements for installing this steering cylinder on a compatible machine frame

You need to have a functional hydraulic steering system and a compatible machine frame before you can install the Power Steering Cylinder.

1. Unpack the cylinder and identify the 16-1/4″ closed length and 23″ open length dimensions.
2. Mount the cylinder using the included hardware to secure the unit to the chassis.
3. Connect the hydraulic hose to the cylinder ports to allow fluid flow from the pump.
4. Verify the hydraulic hose and seals match your machine’s specific pressure requirements before tightening connections.

Warranty and Support: What to Check

Warranty coverage and support terms vary by seller and country.

• Confirm the 30 day return policy applies to your specific purchase to ensure you can return the unit if the 23″ open length does not clear your steering linkage.
• Verify the rod diameter of the Power Steering Cylinder before purchasing a Hydraulic Seal Kit, as this listing does not state the specific rod measurement.
• Check that your hydraulic hose and fittings match the cylinder’s port sizes to prevent fluid leaks.

Test the steering movement through its full range of motion as soon as the unit arrives to ensure the stroke length provides the necessary turn radius.

The Power Steering Cylinder: Remaining Questions

What is the stroke length of the D128454 D84800 234447A1 Power Steering Cylinder?

The Power Steering Cylinder features a 23″ open length, which represents the stroke length or the distance the piston head travels when fully extended. You should confirm your machine’s original factory geometry to ensure this travel matches your steering linkage requirements. Does your specific machine require exactly 23 inches of travel? The Power Steering Cylinder provides this specific measurement to ensure full steering lock without mechanical interference.

What is the return process if the Power Steering Cylinder arrives damaged or doesn’t fit?

The Power Steering Cylinder includes a 30-day return policy for refunds if the part is incorrect or arrives in poor condition. This window provides a buffer for you to verify the fitment against your Case Backhoe Loader model before the return period expires. Because heavy hydraulic components can be difficult to ship, this 30-day window helps mitigate the risk of ordering the wrong part.

Final Verdict on the Power Steering Cylinder

If you are struggling to turn the wheels of a Case Backhoe Loader because the steering feels heavy or unresponsive, the Power Steering Cylinder provides the necessary hydraulic force. This unit measures a 16-1/4″ closed length and extends to 23″ when fully open.

You should verify your specific model’s requirements before ordering. This cylinder fits a wide range of models, including the 480B, 480C, 480D, 480E, 480F, and 580B through 586E series. It is designed to replace several part numbers, including 234447A1 and D84800. Because the steering cylinder (the component that moves the wheels) must align perfectly with your linkage, confirm your mounting points match the steel and plastic construction of this unit.

If you own a Case Backhoe Loader and need to restore steering responsiveness, the Power Steering Cylinder is a suitable replacement for around $152.35. It is a reliable option for those maintaining older B series machines that utilize power steering hose adaptations.

The Power Steering Cylinder holds a 4.4 rating from 26 buyer ratings. This indicates a generally positive experience from a small group of owners who have integrated this part into their equipment.
