Is it easy to replace cylinder seals on a lift?
Seals wear down over a period of time or work their way loose. This will be evidenced by leaking hydraulic fluid from the cylinders. Replacing these seals is easy to do. It requires a simple cylinder seal kit and about an hour. Sure, the instructions ( you can see those here) may make it sound complicated, but we want to show you how simple it is.

Do you need to do a complete rebuild of a cylinder?
It is highly recommended that you conduct a complete rebuild if disassembling a cylinder for any reason. A complete rebuild includes replacement seals, wiper, and wear rings because these are the components that are subject to wear. The seal kit includes only the seals and wipers needed for a cylinder.
What causes a piston seal to fail on a hydraulic cylinder?
Bulletin 1242/1-GB 1 Damaged piston rods or rod bearings are the most common cause of rod seal failure. The usual causes of such damage are poor alignment between the cylinder and its load, resulting in side loading; or a bent piston rod, resulting from the use of an undersized rod in a thrust application.

What to do when oil is leaking from a hydraulic cylinder?
One solution is to relocate the directional valve closer to the cylinder to reduce the line volume to less than that of the cylinder. This allows oil to be flushed from the cylinder to the reservoir, to be filtered and cooled.
What causes a piston rod to leak pressure?
With rod seals of other materials, high pressure leakage is usually the result of inadvertent pressure intensification across the piston. A severe meter-out flow restriction at the head end of a cylinder with an oversized piston rod can expose the rod seal to a back pressure equal to twice the system pressure.
