One of our members wrote me this question:
“One of our customers has a new wheeled excavator. The auxiliary circuit on this machine is controlled by an electronic proportional foot pedal which sends its signal to an ECU. This ECU then sends a variable voltage to 2 proportional solenoids located on the auxiliary circuit sandwich on the main DCV. But … Read more
While absolutely essential on a piston-type hydraulic motor, an external case drain line is usually optional on gear motor designs–external, internal and gerotor/geroller. These types of motors don’t have a large-volume case or sump like piston motors do. But they do have internal leakage which by design, usually accumulates in a small cavity just behind the shaft seal.

Protecting the surface of hydraulic cylinder rods when a machine is idle is particularly important in corrosive environments, such as marine or offshore applications. And even more so if the cylinder rod is finished with conventional, hard chrome plating, which due to its micro porosity, has relatively poor corrosion resistance. The BEST way to keep the surface of the cylinder … Read more
