Often when a cylinder is not performing as it should, the question comes down to, should you repair or replace it? However, replacing a cylinder is a costly exercise, and sometimes repairing it may be the better option.
Power Team SA notes that there are a few parts in a cylinder that can cause the failure. Parts such as the barrel, piston rod, the piston, the cylinder head, the cylinder cap and the seals and bearings can all be responsible. Some explanations of failure can be:
Sometimes a cylinder will fail simply due to the wearing out of a bearing or a seal and the replacement of those components is enough to get your machinery up and running. However, if this is not the case, before any repairs are done, Power Team SA suggests that the cause of the failure needs to be determined. If this is not done, then once the cylinder is replaced, the same damage and failure will continue to occur.
A cylinder should be replaced when the following occurs:
With the correct preventative maintenance in place, a hydraulic cylinder will last longer. Wear and tear do occur, even with a maintenance schedule in place, however at a later time should there be no underlying causes. Components such as hydraulic seals are not always easy to see, and the only way to detect a torn seal is to disassemble and reassemble the cylinder.
Often when a cylinder fails it is a component that fails rather than the entire system. If the failure is found soon, only the damaged part needs to be replaced as is common with bearings and seals.
Before a decision is made to replace or repair a cylinder, the following needs to be taken into account:
These factors will play a part in your decision as to when and how to sort out a cylinder failure. For expert advice Power Team SA are on hand to help with all hydraulic needs, and through years of experience will be able to provide a solution suitable to your needs.
