So I bought a low-rise scissor lift off CL last week.
It was $500 and the guy delivered it to my house.
I bought it out of a field, fluid reservoir open to the elements--so I was not optimistic it was going to be plug&play.
I emptied the tank and replaced with fresh fluid.
The unit will go up and down, but just barely. The system bleeds down with just the weight of the unit itself until the safetys catch it.
It would not hold any significant weight, so I took it apart to find two internal seals had pretty much disintegrated.
Here is where they were, I had already cleaned up the debris on one side.
Here is what was left of the aforementioned seal:
I cannot see much else out of sorts or any other problems. Can the pump internals fail in some way that is not externally observable? Any other common MOFs? I find it a little odd two little o-rings would render the thing inop--but then again it supposedly operates at 2300psi.
I already ordered the seal kit--so hopefully that fixes the problem.
Picture of power unit, I think it is a Rotary PFX1 lift, but I really have no idea as the ID marks are nowhere to be found on the lift and the pump ID plate has faded into nothing.
