Leaking Multi-stage Wedico Ram

[Northwoods Timber toter]

Has anyone found a cure for the Wedico multi-stage ram leaks? Can the cylinders be rebuilt? I've tried thicker fluid (ATF) seamed to work for a while, but then blat! Projected like an infant with a gas bubble after a bottle! Haven't touched in months, I only get a few weeks a year to work on my trucks. I work over seas, so I'm looking for a fairly quick way to fix, correct or even replace (if it's financially reasonable). She spews at almost each stage, enough to make a puddle dumping one load. Hope the EPA doesn't find out! Any fixes or suggestions will be greatly appreciated!!
