ZTUOAUMA Power Steering Cylinders Review: Fits Earlier B Series with Adapted Hoses

The Power Steering Cylinders in Short

ZTUOAUMA Power Steering Cylinders move the steering linkage with a 16-1/4″ closed length for owners of 2-wheel drive Case Backhoe Loaders or Harvesters.

Operating a heavy harvester becomes significantly smoother when the steering actuator provides consistent hydraulic response across the full 23″ open length. This stroke length determines the distance the piston head travels, ensuring the operator can turn the machine with minimal physical effort.

The ZTUOAUMA Power Steering Cylinders achieve this range of motion to support 2-wheel drive machines. With a 16-1/4″ closed length, these units provide the necessary leverage for heavy-duty steering while maintaining the compact footprint required for the 480 and 580 series.

We evaluated 11 steering cylinders and selected this model for a full review because it is one of the most-rated products that passed screening, holding 17 buyer ratings. This review is for owners of older B series machines looking for a reliable replacement.

The Short Answer on the Power Steering Cylinders

Best for: you own a Case Backhoe Loader or Harvester in the 480 or 580 series and need to replace the steering cylinders on a 2-wheel drive machine.

The ZTUOAUMA Power Steering Cylinders are a practical choice for these specific models at the $145 price point.

• Pro: The 23″ open length provides the necessary reach for the stroke required by the 480 and 580 series.
• Pro: This listing includes 2 cylinders, bringing the cost to $72.50 per unit.
• Con: The 16-1/4″ closed length may result in mechanical interference if your mounting distance is shorter than the stated spec.
• Con: Compatibility is limited to earlier B series only when used with adapted power steering hoses.

Don’t buy this if: your machine is a 4-wheel drive model or requires a cylinder with a different stroke length than the 23″ open reach.

Price assessment: The $145 price is fair for a dual-unit package that covers the primary steering requirements for these heavy equipment models.

Key Specifications for the Steering Cylinder Pack

The Open Length of 23″ measures the distance the piston head travels from the closed position to the fully extended position.

Before You Buy: Steering Cylinder Checklist

The first thing to check is whether your machine’s hydraulic system is compatible with the cylinder’s pressure and stroke requirements to ensure full steering range.

• ☐ Confirm the machine is a 2-wheel drive model — using these on a 4-wheel drive system may lead to incorrect steering geometry.
• ☐ Measure the required stroke length and compare it to the 23″ open length — a cylinder with too short a stroke prevents full steering lock, while one with too long a stroke causes mechanical interference.
• ☐ Verify the pump’s output pressure against the cylinder’s bore pressure rating — using a cylinder with a lower PSI rating than the pump output causes seal blowout or structural failure.
• ☐ Check for hose compatibility with earlier B series machines — these are compatible with earlier B series with adapted power steering hoses, otherwise you may need to custom-fabricate fittings.
• ☐ Budget for a pair of units — this listing includes 2 power steering cylinders, meaning you do not need to purchase a second set separately.

You should not buy these Power Steering Cylinders if your machine requires a 4-wheel drive configuration or if your existing hydraulic lines cannot be adapted to the specified hose ports.

What the Numbers Mean in Use

23 Inch Open Length Reach

When you need to confirm if the steering linkage has enough travel to reach full lock, the Power Steering Cylinders provide an open length of 23 inches. This measurement defines the total extension of the cylinder, allowing for the specific steering range required by heavy-duty machinery like a Case Backhoe Loader.

You must ensure your mounting points accommodate this extension to prevent mechanical interference when the wheels are turned to their furthest positions.

How dual hydraulic line ports improve fluid flow efficiency

Managing hydraulic fluid flow becomes more efficient with the two hydraulic line ports provided on the Power Steering Cylinders. These ports allow for a standard dual-line setup, which supports the flow requirements of heavy machinery steering systems.

Having two lines allows for a balanced hydraulic circuit, which helps maintain consistent pressure during operation. Because the listing specifies two lines, you can plan your hose routing to ensure the fluid path remains clear and capable of handling the required pressure for 2-wheel drive machines.

Compatibility of this Steering Cylinder with earlier B series machines

Matching a replacement cylinder to an older machine often involves navigating different hose configurations on older models. The Power Steering Cylinders are compatible with earlier B series machines, provided you use adapted power steering hoses for the connection.

This compatibility allows you to maintain the steering system on older 480 or 580 series models without replacing the entire hydraulic assembly. Since the fit requires adapted hoses, you should verify your existing hose fittings before ordering to ensure they can be transitioned to this specific cylinder’s ports.

How the Power Steering Cylinders Compares to Alternatives

The ZTUOAUMA D128454 D84800 234447A1 Power Steering Cylinders offer a lower price point than most alternatives while providing a dual-cylinder set.

• The ZTUOAUMA Power Steering Cylinders cost $145, making them $13.41 cheaper than the BUYAUTOPARTS! 84-50012AN Power Steering Ram Assist Cylinder.
• The D4NN3A540A Power Steering Cylinder 5/8″ Rod is $24 more expensive than these ZTUOAUMA units.
• The Total Power Parts 1201-1602 Right Steering Cylinder is $18.06 cheaper than this model.

If you require a single-unit cylinder or a specific 5/8″ rod diameter for a Ford tractor, the D4NN3A540A Power Steering Cylinder 5/8″ Rod is the alternative to consider.

Getting the Power Steering Cylinders Working, and What to Check After

Preparing the 2-wheel drive machine for Steering Cylinder installation

You must have a 2-wheel drive machine with the compatible hydraulic lines ready before installing the Power Steering Cylinders.

1. Unpack the two Power Steering Cylinders from the package.
2. Mount the cylinders to the frame using mounting hardware that matches your chassis bolt pattern.
3. Connect the hydraulic lines to the two ports on each cylinder.
4. Attach the hydraulic hose to the pump to transmit pressurized fluid to the cylinders.

Warranty and Support: What to Check

Warranty coverage and support terms vary by seller and country.

• Confirm the rod diameter of any purchased Hydraulic Seal Kit matches the Power Steering Cylinders to ensure it allows for leak repair.
• Verify the mounting orientation of the cylinders to ensure the ports align with your steering linkage.
• Check that the hydraulic hose connections are secure to prevent fluid loss under pressure.

Test the steering movement for full range of motion as soon as the cylinders are installed to ensure the 23″ open length provides sufficient travel for your specific machine.

What Buyers Still Want to Know About This Steering Cylinder

What is the actual stroke length when fully extended?

You should measure your loader’s required travel and confirm it aligns with this 23-inch specification before ordering to ensure full steering lock.

Is the 6-month return window enough if I find a mounting issue?

The 6-month return window allows for a return if the Power Steering Cylinders do not align with your mounting points upon arrival. Because hydraulic components are heavy and difficult to ship, confirming your mounting orientation before purchase ensures you do not lose the cost of the unit or the time spent on a failed installation.

Will these fit my Case 480 series backhoe?

Yes, the Power Steering Cylinders are compatible with Case 480B, 480C, 480D, 480E, 480F, and 480SE models. These units are designed for 2-wheel drive machines and can be used on earlier B series models if you use adapted power steering hoses.

How many cylinders come in this package?

This package includes 2 Power Steering Cylinders, which provides a pair of units for a total cost of around $145. Having a pair ensures you have the necessary hardware for a complete steering system replacement.

What is the closed length of the unit?

The Power Steering Cylinders have a closed length of 16-1/4 inches, which defines the footprint of the cylinder when the rod is fully retracted. You must verify this dimension against your existing mounting brackets to ensure the cylinders sit correctly in the frame.
