C1Hydraulic cylinder repair: how it works

When to get in touch

• Oil leaks at the piston rod or the gland
• The boom, bucket or load drifts down on its own
• The cylinder moves more slowly, jerks or loses force
• The piston rod is scored, corroded or bent
• Worn mounting eyes or bushings

How the repair works

1. Intake and inspection

   We inspect the cylinder and find out how it failed and what machine it works on. If you can, bring in only the cylinder, not the whole machine.

2. Dismantling and cleaning

   We dismantle the cylinder and clean the parts so that all damage is visible.

3. Measuring and fault assessment

   We inspect and measure the piston rod, barrel, piston and gland, looking for scoring, wear and bending. We decide what can stay, what needs restoring and what has to be made new.

4. Barrel honing

   If the inner surface of the barrel is damaged or worn, we hone it so the new seals seal tightly again.

5. Making new parts

   We make a new piston rod, barrel or other damaged part in our own workshop. We turn parts up to 4.5 m long and 380 mm in diameter.

6. Seal replacement

   We replace the seals and, if needed, the bushings, selecting them to suit the cylinder's dimensions.

7. Assembly and pressure testing

   We pressure test the assembled cylinder and make sure it is leak-free and working before we return it to you.

Why repair instead of buying a new cylinder

A repair replaces only the worn parts, so it usually costs far less than a new cylinder. The rebuilt cylinder is the same one that was on your machine, so there is no need to adapt mounts or connections.

New cylinders for older machines are often no longer made, or you have to wait weeks for them. In that case we make the part you need from the old sample.
