50 years of reliable service, but look at what was hiding inside!!
During a recent cylinder replacement, we needed to drain down an old inverted cylinder featuring a top port. To properly evacuate the fluid, we drilled a small drainage hole near the base.
Instead of clean hydraulic oil, out came a heavy mixture of rust sludge and particulate contamination.
What's remarkable is that despite decades of build-up, this lift ran faultlessly for over half a century. Because it was an inverted setup, gravity worked in our favor—the heavy debris settled harmlessly at the bottom rather than circulating continuously and scarring the main ram.
It’s a testament to the sheer durability of legacy engineering, but also a reminder of why planned maintenance and eventual component upgrades are so critical.
Have you ever opened up legacy equipment and been surprised by what you found inside?
