[TR] Hydraulic Jack Question

[Bob Danielson]

What causes a jack or even an engine crane to stop holding a position and
settle back down after a while? Is it low fluid or a bad gasket or a
combination of things? I know that there's an industry standard for how much
one can drop over an x period of time. But I'm talking about a matter of
minutes with or without a load on it?
