One of the key components in fluid power systems is the hydraulic cylinder. This device utilizes the pressure created by hydraulic fluid to create linear movement. It is due to this reason that we see the widespread use of hydraulic cylinders in many machines.
Due to high pressure and tough operating conditions, this component wears out after some time. Many operators choose to replace hydraulic cylinders once they fail. However, we have found that there is not always a need to go through this step, especially when a hydraulic cylinder repair service like Coastal Hydraulics can restore performance effectively.
Why You Should Consider Rebuilding Your Machine
Many operators tend to wait until their machinery breaks down completely. However, we know that early detection helps us identify problems before they escalate into major failures that could bring about expensive repairs. By performing regular inspections on your machinery, we help extend its useful life.
Spotting Warning Signals Early
One way to detect when your hydraulic cylinders need attention is by observing how your machinery performs daily. As soon as you discover physical damage to the cylinder rod, take action immediately. Scratches, pitting, or scoring on the rod will lead to destruction of seals and leakage of fluid.
Other signs to look out for include noises produced by your machinery. Groaning or squeaking are common sounds produced when there is fluid bypassing the piston seal. If you’re wondering how to rebuild a hydraulic cylinder, our technicians look for more subtle signs like worn or broken mounts. The presence of such issues forces the machinery to move out of alignment, hence quick wearing out of the internal parts.
Spotting Issues with Fluid Bypassing and Leaks
It is very hard to miss fluid leaks from your machine. You can spot puddles of hydraulic oil near the seal or fitting points of your machinery. Internal leaks prove trickier because you might not detect them until the damage is already severe. If your loader arms gradually lower when your machinery supports heavy loads or feels sluggish, there could be fluid bypassing the seals.
We diagnose these issues by measuring the pressure in the cylinder as well as its cycles per minute. Once we establish that the cylinder has a problem holding pressure or is moving slower than the manufacturer recommended, we advise rebuilds.
What Happens During Hydraulic Cylinder Rebuilds
You should never attempt hydraulic repairs when you do not have experience. We suggest that you leave the task to skilled professionals who can perform the work efficiently. We first start by taking the entire machine apart in a controlled environment. Our goal is to ensure that there is no contamination during this procedure since it is a major contributor to failure of hydraulic machines.
After disassembly, we clean and carefully check each and every component of the machine. We look for damage caused by scoring or ballooning of the barrel during the process of rebuilding hydraulic cylinder systems. We also inspect the rod for proper straightness. After changing the seals, O-rings, and hard parts, we put the whole machine back together using appropriate torque. We then place the rebuilt cylinder on a special testing station to cycle it to maximum pressure.
Choose the Right Solution for Maintaining Your Machinery
Your machinery does not have to consume your profits to keep operating. There is usually no need to incur extra expenses when you choose to rebuild the faulty machinery.

FAQs
How Long Does The Process Of A Cylinder Rebuild Take?
This process can take a day or two, depending on the size and extent of damage in the unit. Custom machining may be required to re-chrome or repair the rod, hence taking some extra time. Nevertheless, we strive to deliver your machinery on time so as to reduce downtime.
Are Rebuilds Less Expensive Compared To Replacements?
Yes, rebuilding is cheaper than buying new units. This is especially so for old or large cylinders that require expensive replacement parts, as well as specialized hydraulic cylinder rebuild tools. However, we might advise you to purchase new units when there is irreparable damage to your machines.
Do Rebuilt Cylinders Perform Just Like New Ones?
Yes, rebuilt units perform like new units since they undergo rigorous testing before release. We install quality seals and machine the hard parts so that they meet the original factory specifications. We also subject each and every cylinder to rigorous pressure testing to enhance longevity.
