As soon as you have come to the realization that your hydraulic cylinder is no longer working properly, you will need to start taking action. Not sure if the problem that you are experiencing is truly your hydraulic cylinder that is giving you problems? Simply review the following signs of hydraulic cylinder trouble and you should be able to figure out from there what you need to do.
Trouble With The Mountings
It is important to first make sure that you have determined whether your hydraulic cylinder is made to work with pivot or fixed mountings. This is important because the problems associated with each will be a little different. For example, the pivot mountings are required to be fully lubricated at all times. If the lubrication is always wearing off a little too fast, there is a chance that there something misaligned that are causing things to performance improperly. With the fixed mountings, there could not be any movement between the various mounting surfaces. All of the bolts should be perfectly tight as well.
You Are Noticing A Leak
A leak that is below the the gland, or that is landing on top of the piston rod is a sure sign that there is a problem with your hydraulic cylinder. This is something that commonly happens when the seals are becoming worn out. In many cases, you will find that simply having the seals replaced as soon as possible will allow the cylinder to begin performing properly again.
You Spot Damage On The Piston Rod
If you are suspecting that you have a cylinder problem, you will want to take the time to take a very close look at the piston rod itself. Make sure that you are looking over the full length of the rod in order to get an accurate understanding of its condition. Problems such as pitting or scoring on the piston rod, as well as if the rod is bent even the slightest bit, means that you have a hydraulic cylinder that is ruined. It will need to be completely redone or even completely replaced.
