In order to restore the condition or performance of hydraulic cylinders, they can go through a rebuilding process. It's a restoration that you want to approach very carefully as to have success. Here are some tips that will keep you on the right paths throughout a hydraulic cylinder rebuild.
Look at Diagrams Before Disassembling
You'll have to disassemble the hydraulic cylinder in order to rebuild it, but prior to doing so, go through diagrams of your exact hydraulic cylinder. You need to see where certain components are to have a smother disassembling process, where components aren't damaged further.
Looking at these diagrams also gives you insights into how the hydraulic cylinder should be put back together once the rebuild is finished. That will save you time and ensure the assembling process leaves behind a well-functioning cylinder that you don't have to further address, at least for a while.
Check Components Against Their Spec Tolerances
Each component on a hydraulic cylinder will have certain spec tolerances. They are determined by your hydraulic cylinder's manufacturer. What you should do before getting started with this rebuild is check each component against their manufacturer's spec tolerances.
Then you'll gain meaningful insights on various aspects, including surface finish, thickness, material hardness, and crack development. Gaining concrete data on these aspects will help you decide if a repair or replacement is needed for various parts of your hydraulic cylinder. Then you can make sure your rebuild is set up to maximize cylinder performance after you get done.
Replace Parts When Necessary
If you're not able to repair parts of a hydraulic cylinder when going through a rebuild, you'll have to find part replacements. It may be the seals, nuts, pistons, caps, rod seals, or the washer element. You just need to perform detailed inspections and potentially consult with hydraulic cylinder experts.
If you come across a severely damaged part and aren't sure if it can be restored, you can have the condition looked over by a hydraulic cylinder expert. Then if they agree the component can't be repaired meaningfully, you can start looking at replacement options.
If you have a hydraulic cylinder that's giving you performance issues or you can clearly see signs of damage, a rebuild may be in order. As long as you focus on the right aspects and get ready for this restoration well in advance, you'll have more control over how it turns out.
