Hydraulic cylinders are an essential component in many industrial applications, such as construction equipment, agricultural machinery, and heavy-duty trucks. These hydraulic systems are used to convert fluid power into mechanical power. Thus, enabling the machines to lift heavy loads and perform various tasks. However, hydraulic cylinders can wear out over time, resulting in leaks, scratches, or other types of damage. Fortunately, there are several tools for hydraulic cylinder repair available, allowing you to avoid costly replacements and keep your machinery running smoothly.
In this article, we will explore the different tools required to repair hydraulic cylinders, the average cost of rebuilding a hydraulic cylinder, and how to fix common issues such as leaks and scratches.

What Tools are Needed to Repair a Hydraulic Cylinder
What Tools are Needed to Repair a Hydraulic Cylinder1. Hydraulic Cylinder Repair Stand
A hydraulic cylinder repair stand is an essential tool for safely repairing hydraulic cylinders. These stands provide a stable base for the cylinder, allowing you to work on it without the risk of the cylinder falling or rolling away. They also have adjustable supports, allowing you to position the cylinder at the right height for repair work. HEMS have a wide range of stationary benches for cylinder repair. Amongst these are Hydraulic Cylinder Servicing Benches such as the HCS-60-L. There are many other models so you can tailor your bench to your needs. Also, this range has a Cylinder Barrel Washer, the CBW-300. The final product in this range is Hydraulic Cylinder Tester, the HCT-3000.
2. Cylinder Hone
A cylinder hone is a tool used to remove scratches and imperfections from the cylinder bore. This tool is essential if you want to restore your hydraulic cylinder to its original performance. HEMS also supply a state-of-the-art Cylinder Honing Machine, called the HEM CH14. This mark of innovation as a fully automated design meaning once the honing settings are in place, the operator can start honing without the need to maintain proper feed during the honing process.
3. Hydraulic Cylinder Testing Tools
After repairing a hydraulic cylinder, it’s essential to test it before reinstallation. Testing tools such as a hydraulic flow meter, pressure gauge, and a cylinder bore gauge can help you test the cylinder’s performance and ensure that it’s safe to use. As well as the aforementioned tester, HEMS have an Automatic Digital Cylinder Tester, the HE-ACDT. You can view this product and watch a video on it by clicking the hyperlink.
4. Hydraulic Cylinder Disassembly Tools
To disassemble a hydraulic cylinder, you will need various tools such as a cylinder puller, rod nut wrench, and a seal removal tool. These tools will help you safely disassemble the cylinder without damaging the internal components.
5. Hydraulic Cylinder Reassembly Tools
Reassembling a hydraulic cylinder requires different tools such as a rod straightener, gland nut wrench, and a seal installation tool. These tools are necessary to ensure that the cylinder is properly reassembled and does not leak.

Is it Easy to Rebuild a Hydraulic Cylinder?
Rebuilding a hydraulic cylinder involves disassembling the cylinder, inspecting it for wear and tear, replacing damaged parts, and reassembling it. While the process may seem daunting, it’s relatively simple with the right tools and knowledge.
However, rebuilding a hydraulic cylinder requires precision and attention to detail. If you’re not familiar with the process, it’s best to leave it to the professionals to avoid causing further damage to the cylinder.
Can you Fix a Leaking Hydraulic Cylinder?
Leaking hydraulic cylinders can cause significant damage to machinery, leading to costly repairs and downtime. Here are some steps to stop a hydraulic cylinder from leaking:
1. Identify the Location of the Leak
The first step in stopping a hydraulic cylinder from leaking is to identify the location of the leak. Check the cylinder and its components for any visible signs of leakage, such as hydraulic fluid on the surface or around the fittings.
2. Tighten Fittings
If the leak is coming from a fitting, tighten the fitting to the recommended torque specification. Use a wrench to tighten the fitting, being careful not to overtighten it, which could cause damage to the fitting.
3. Replace Seals
If the leak is coming from a seal, replace the seal using the seal kit. Remove the damaged seal and replace it with a new seal of the correct size and shape. Make sure to install the seal correctly, lubricate it, and ensure that there is no debris that could cause damage.
4. Repair Scratches
If the leak is coming from scratches on the cylinder’s surface, use the cylinder hone to remove the scratches. Removing the scratches will ensure that the seals sit flush against the cylinder’s surface and prevent leaks.
5. Use Sealant
If the leak persists, apply sealant to the area around the leak. The sealant will fill any gaps or imperfections, preventing hydraulic fluid from leaking out.
How do you Stop a Hydraulic Cylinder from Leaking?
If you are experiencing a leak in your hydraulic cylinder, it can be a frustrating and costly problem. Now that you know what to do if you have a leak, the next thing you need to know is how it could have been prevented in the first place. Although sometimes a leak can be out of your control, the best thing you can do is indulge in proactive maintenance. Additionally, regularly scheduled maintenance and inspections can help prevent leaks from occurring in the future.
How do you Fix a Scratch on a Hydraulic Cylinder?
Scratches on a hydraulic cylinder’s surface can cause leaks and other issues. However, they can be fixed with cylinder honing. The hone uses abrasive stones to remove the scratches, ensuring that the cylinder’s surface is smooth and free from imperfections.
What is the Average Cost to Rebuild a Hydraulic Cylinder?
The cost to rebuild a hydraulic cylinder depends on the extent of the damage and the type of machinery. On average, the cost can range from $300 to $1,000 or more, depending on the size of the cylinder and the repair required.
Tools for Hydraulic Cylinder Repair: Conclusion
Repairing hydraulic cylinders is essential for ensuring the smooth operation of machinery and prolonging its lifespan. With the right tools and knowledge, repairing a hydraulic cylinder is a simple and cost-effective process. Therefore, identifying the problem, disassembling the cylinder, inspecting it, replacing damaged parts, and reassembling it are crucial steps in the repair process.
In addition, stopping a hydraulic cylinder from leaking, fixing scratches, and rebuilding the cylinder are all important aspects of hydraulic cylinder repair. Be sure to take the necessary safety precautions when working with hydraulic equipment to prevent injuries and accidents.
