Hydraulic cylinders are a crucial component in many industrial applications, from construction equipment to manufacturing machinery. However, like any mechanical device, hydraulic cylinders can suffer from wear and tear over time, leading to leaks, malfunctions, and even complete failure. In this article, we will discuss everything you need to know about hydraulic cylinder repair, including common issues, cost, and the repair process.

Common Hydraulic Cylinder Issues

Hydraulic cylinders are designed to withstand high pressure and heavy loads. However, over time, several issues can arise that can cause the cylinder to fail or malfunction. Here are some of the most common hydraulic cylinder issues:

1. Leaking seals

Firstly, hydraulic cylinders rely on seals to keep the pressurised hydraulic fluid inside the cylinder. When these seals wear out or become damaged, they can lead to leaks, which can cause the cylinder to lose pressure and fail to function correctly.

2. Bent or damaged piston rods

Also, the piston rod is a critical component in the hydraulic cylinder that converts hydraulic pressure into linear force. If the piston rod becomes bent or damaged, it can cause the cylinder to stop working or malfunction.

3. Contaminated hydraulic fluid

Hydraulic fluid is crucial for the proper functioning of the hydraulic cylinder. If the fluid becomes contaminated with dirt, debris, or other impurities, it can cause the cylinder to malfunction or fail.

4. Corrosion or pitting

Finally, hydraulic cylinders are often exposed to harsh environmental conditions, which can cause corrosion or pitting of the cylinder walls. This can lead to leaks or other issues that can affect the cylinder’s performance.

HCS-60-LCan a Hydraulic Cylinder be Repaired?

The good news is that in many cases, a hydraulic cylinder can be repaired rather than replaced. However, the extent of the damage will determine whether repair is feasible. If the damage is extensive or the cylinder is beyond repair, replacement may be the only option.

How Much Does it Cost to Repair a Hydraulic Cylinder?

The cost of repairing a hydraulic cylinder will depend on several factors, including the extent of the damage, the size of the cylinder, and the cost of replacement parts. On average, hydraulic cylinder repair costs can range from $400 to $1,000 or more.

How Do You Fix a Leaky Hydraulic Cylinder?

Fixing a leaky hydraulic cylinder will depend on the cause of the leak. In some cases, replacing the seals or gaskets may be sufficient. However, in other cases, more extensive repairs may be required. Nevertheless, it is always best to consult with a professional hydraulic cylinder repair service to diagnose the issue and recommend the appropriate repair. Of course, this is unless you plan on buying your own hydraulic cylinder repair products. You can view HEMS’s range here


Is it Easy to Rebuild a Hydraulic Cylinder?

Rebuilding a hydraulic cylinder is a complex process that requires specialised knowledge and tools. While some minor repairs, such as replacing seals or gaskets, may be feasible for a skilled DIYer, most repairs will require the services of a professional hydraulic cylinder repair service.


Can You Fix a Pitted Hydraulic Cylinder?

In some cases, a pitted hydraulic cylinder can be repaired by honing or reaming the cylinder walls. However, if the pitting is extensive, the cylinder may need to be replaced.

What Causes a Hydraulic Cylinder to Stop Working?

Hydraulic cylinders can stop working for several reasons, including:

  • Damaged or worn seals
  • Bent or damaged piston rods
  • Contaminated hydraulic fluid
  • Corrosion or pitting of cylinder walls
  • Malfunctioning hydraulic pump or valve
