Hydraulic Cylinder Repair Tips

hydraulic cylinder repair

Hydraulic cylinders form an integral component of the hydraulic system. They function as an actuator mechanism that produces unidirectional force. Integrating hydraulic cylinders can remove the need for gears and levers. 

Both mobile(hydraulic cranes, presses forges, packing equipment) and industrial systems(agricultural equipment, construction vehicles, marine equipment) employ hydraulic systems. You can check them at RIVERLAKE. Of them, the majority of them utilize hydraulic cylinders to lift, grip and pick.

Every hydraulic system comprises fundamental components like valves, pumps, cylinders, filters, etc. Hydraulic cylinders are one of the least complicated parts on the list of features. Therefore, they are simple to maintain and repair. Anyone with a basic understanding of the hydraulic system could repair hydraulic cylinders. 

How to start repairment?

Before you repair, wash the surface and remove the plugs and hoses connected to it. After disconnecting the components, remove all the fluid within the cylinder. Then, we can begin to repair your hydraulic systems. To do this, we require tools. A good seal kit with a rubber mallet, screwdriver punch, pliers, Emery cloth, and a torque wrench are all needed to fix it. 

Leaks in a hydraulic cylinder are the most typical problem that requires the repair of a cylinder. It is necessary to disassemble the cylinder, identify the root of the problem and repair or replace damaged components, and then rebuild the cylinder are actions involved in repairing cylinder. When performing hydraulic repairs to a cylinder, you should always consider the tips below for repairing the cylinder.

Tip #1. Make sure you have the proper tools.

It is necessary to have special tools to take the cylinder rod from the tube and make the required repairs. The most common tools are circlip pliers, wrenches and screwdrivers, emery cloth, etc. The tools you will require depend on whether you want to repair the wire ring cylinder or the threaded head cylindrical.

You should only start repairing with the right tools. Using the wrong tools can cause metal-to-metal contact with the bore of the cylinder and cause scratching, bending, and other issues.

Tip #2. Make sure you’ve got the right components and parts.

After determining the cause of the issue, You must ensure that you have all the necessary parts and the components needed for the repair. Different kinds of Cylinders require additional parts.

Whatever the fix, regardless of the repair, you’ll require O-rings and other kinds of seals since you will need to perform a complete rod seal replacement every time you remove the cylinder housing and remove the rod of the cylinder.

Tip #3. Disassemble it and check the components and cylinders.

You must ensure that the rod of your cylinder isn’t damaged or bent. If that happens, this could indicate a larger issue that needs to be addressed.

Make sure to examine the seals on the rod to see if they’re not properly formed, which could signify that the rod has been bent. In addition, examine the bore of your cylinder for pitting, rust scratching, or scoring since these could result in leaks.

Tip #4. Make sure to put on new wear bands.

Similar to other piston seals, it is necessary to replace the gland seals. The gland seals stop the oil from spilling out the end of the piston. They also stop the rod from forming a metal-on-metal connection to the inside of the gland.

Tip #5. Completely inspect the hydraulic piston.

It is essential to examine all seals, fittings, rods, fittings, and other components crucial to the operation of the cylinder before beginning the repair procedure. Sometimes, the cause of failures isn’t in the cylinder but could be just as easy as a leaky hose.

Tip #6. Pay focus to the rod assembly when you dismantle it.

It’s a good idea to snap photographs from the rod assembly to ensure that you have the piston seals, high-tension springs if employed, and other components in their correct place. If installed in the right locations, it could make them easier to put them back together and cause the assembly to perform differently than intended.
