Thought this might be of help if your LCI Level Up system has a leaking jack. LCI doesn't sell seal kits for them but I did get some from a hydraulic shop.

The forum would only allow 5 pictures to be uploaded so I had to break this up into 3 posts.

My Momentum has been sitting throughout the winter with no issues and then one day I noticed hydraulic fluid on the pad of one of my levelers. The top of the leveler and the hoses were completely dry.

I retracted the right side jacks, removed 4 of the 6 retaining bolts and loosened the remaining 2. I marked and disconnected the 4 lines and removed the final 2 mounting bolts and brought it inside to see what I could do. It was either leaking fluid from the leg or from the joint between the bottom cap and the cylinder. Since the top wasn't leaking, I didn't disassemble it. I lost maybe a cup of fluid when removing the lines.

One of the bottom bolts was a different style. This bolt has a sealing washer under it and when the bottom cap is removed the cylinder body has an o-ring for this bolt hole.

Have plenty of rags handy and maybe a bucket too.
