Hydraulic Cylinder Repair in Auckland – When to Repair vs Replace

When a hydraulic cylinder starts leaking, losing power or moving unevenly, the question most people want to know is, can it be repaired, or does the whole cylinder need replacing? And, while we’d love to say a quick repair is always possible, in some cases, it’s not the best long-term option.

Common Causes of Hydraulic Cylinder Damage

Most hydraulic cylinder failures come back to a combination of wear and tear, and poor maintenance. 

Seals wear out, rods become scored, bent or corroded, and dirty hydraulic fluid damages internal parts. Add any overloading, pressure spikes or environmental damage, and a weakened cylinder will be pushed beyond what it can handle.

Signs Your Hydraulic Cylinder Needs Attention

In our experience, a cylinder will usually give you a few clues that there’s trouble coming before it fails completely:

• Oil around the seals
• Slow or uneven movement
• Loss of power
• Excessive noise or vibration
• Reduced machine performance
• Scratches, pitting or bending on the rod
• Hydraulic fluid spraying under pressure

If hydraulic fluid is spraying out forcefully, treat it as more than a leak. Shut the machine down, keep clear, retrieve a spill kit if available, and follow your site H&S protocols before going any further.

When Hydraulic Cylinder Repair is the Best Option

Hydraulic cylinder repair is usually the cheaper option, so it’s the first thing we look at. If the barrel and major components are still in good condition, repair can be the fastest way to get things moving again.

When You Should Replace a Hydraulic Cylinder

If repair costs start bordering on replacement costs, or you’ve experienced repeat failures, we may recommend hydraulic cylinder replacement. We also offer cylinder manufacturing if a new or custom solution is needed.
