Signs Your Cylinder Requires Repair Services

There are a number of safety and efficiency concerns related to a damaged hydraulic cylinder. Compare these signs and symptoms of a damaged hydraulic system to see if you need our hydraulic cylinder repair services for your equipment:

  • Compromised cylinder mountings
  • Leaking hydraulic fluid
  • Cracked piston, barrel or other components

Cylinder mounts need to be secure to prevent the pressure of your hydraulic system from separating the cylinder from your equipment. A leaking line or cylinder is typically caused by a broken seal or compromised fitting. Finally, cracks, rust or other structural damage to your cylinder need to be repaired immediately to prevent sudden failure.

Not all cylinder issues offer warning signs. Sudden failure requires emergency repair services. Our team of skilled technicians can rapidly respond to your emergency situation to minimize downtime and prevent further damage to your industrial equipment.

Tips on How To Repair a Hydraulic Cylinder

While you may think that hydraulic cylinder repair is an easy task, but as with many projects, it can quickly become complicated when you don’t have the right preparation, expertise, or tools. At Yates Cylinders, we understand that desperate times call for desperate measures, so we want to provide guidance for our customers who want to try and address issues themselves before calling in the professionals.

The following instructions should get your hydraulic cylinder back into production. By performing these suggested steps, you should be able to stop a leaking cylinder. If not, remember that we are committed to serving you with 24/7 emergency service at all our locations.


The proper preparation can set you up for an easier and quicker hydraulic cylinder rebuild. First, clean the unit. Once the cylinder is clean, disconnect the hoses and plug both the ports and hoses securely. Now you can remove and clean the unit. Drain the hydraulic fluid by opening the cylinder ports.
Once you have drained the hydraulic fluid, you should identify the type of cylinder. The most common ones are either wire ring or threaded head cylinders. Now you can assemble your tools to disassemble, repair, and reassemble the cylinder. You will need one or more of the following:

  • Cleaning rags
  • Compressed air
  • Emery cloth
  • Pliers
  • Petroleum-based solvent
  • Proper seal kit
  • Punch
  • Rubber mallet
  • Screwdriver
  • Torque wrench

Repairing a Wire Ring Cylinder

You’ll need to disassemble the wire ring cylinder by retracting the rod assembly ad removing the external steel wire ring. Remove accumulated dirt or oil from around the cylinder head. Using your mallet or punch, push the head into the cylinder tube until you can see the internal groove and reach the internal wire ring. Using the plastic removal ring from the seal kit, insert it into the internal groove with the feathered end pointed toward the tube.

Hold one end of the ring tightly in the groove with a screwdriver while inserting the other end into the groove. Both tips should snap in fully and securely before attempting to remove the rod to prevent them from being caught between the head and tube. You should now be able to extend the rod to pull the head from the tube.
Take out the removal ring as well as the locknut, piston, and head. Clean with the solvent, then closely inspect the parts for damage like the presence of burrs, scratches, or scuffs. Polish and smooth as needed. Now you can access the seals for replacement.

Repairing a Threaded Head Cylinder

Begin your threaded head cylinder disassembly by loosening the set screw and the end cap and removing the piston, rod, and gland assemblies. Loosen the lock nut to remove the piston from the rod assembly. Once the piston is out of the way, remove the seals and clean parts with the solvent. Inspect the cylinder tube, rod, and piston for damage and polish where necessary.

Replace seals and reinstall the rod, then secure the piston to the rod with the lock nut. Lubricate the seals and inside the tube with hydraulic oil, then install the piston, gland, end cap, and rod. You can use Loctite anti-seize on the threads before replacing the cylinder end-cap. Finally, tighten the cylinder and set the screw to the appropriate torque.

After Cylinder Repair

After the repair, you should be able to diagnose the cause of the issue by examining the type of damage. This step is critical to keep from repeating the rebuild and repair process. Our experienced technicians can help you to identify signs of problems and address the source of the problem.
