3 Tips To Save Time And Money When Repairing A Hydraulic Cylinder

3 Minutes Posted on:

The hydraulic cylinder is one of the most critical parts of many industrial machines and vehicles. Consisting of a full system of pistons, valves, and pumps, a hydraulic unit allows the equipment to lift, press, or push something in a linear motion. When one or more of the hydraulic cylinder's components become damaged, the machine might fail to serve its purpose, resulting in productivity losses and time spent to fix the problem. These tips can help you restore a hydraulic cylinder and get back to business.

1) Utilize the correct tools.

Repairing a hydraulic cylinder can be a daunting task. In most cases, you will need to disassemble the hydraulic cylinder entirely to complete the repairs. Being prepared with the right tools, however, will help the process go smoothly. To guarantee that you will be in good shape to handle any possible malfunction, be sure to gather these tools before you start:

  • Pliers
  • Torque wrench
  • Screwdrivers
  • Seal kit
  • Rubber mallet
  • Punch
  • Emery cloth

2) Measure the seals properly.

If the problem with the hydraulic cylinder is due to a faulty seal, it's important to use the correct size replacement seal. One common mistake made during a repair is measuring the old seals. This can cause issues when you attempt to install a new seal, because the current seal may have either expanded or contracted over time. Certain weather conditions (such as extreme heat) and wear and tear from regular operation can drastically change the dimensions of the seal. 

To get the proper measurement for a replacement seal, use a vernier caliper to calculate all of the seal grooves. You will need to provide the diameter, depth, and width of the grooves to a seal supplier to be sure that you are using the right parts. If all else fails, you can reach out to the manufacturer to verify the appropriate hydraulic seal kit you should order.

3) Don't neglect the other components of the hydraulic system.

Instead of only looking at the broken elements, take the time to inspect all of the parts on the hydraulic unit and check for any additional adjustments that might need to be made. This will ensure that you won't have to perform another repair job shortly after this one. Confirm that there are no leaks or poor connections in any seals or lines. Look for signs of wear or breakage on belts or bearings, and don't forget to check motors, valves, and pumps for fractures or cracks. 

You should also try to identify what caused the issue to happen in the first place. Perhaps there is a bigger problem with the hydraulic system that must be tackled to give you peace of mind that the same repair won't need to be repeated again right away. A thorough examination of the entire system may uncover loose couplings, insufficient fluid levels, dirty filters, or other complications that can be serviced now to avoid costly repairs in the future.

Whenever a hydraulic cylinder becomes inoperable, productivity can suffer. By using the right tools and checking all the parts of the unit, you can have everything back up and running. For further assistance, contact hydraulic cylinder repair companies.
