1.5 Servoactuators.
A servo-actuator is a device, which can be used to take the place of the standard hydraulic cylinder. It combines
the cylinder, DCDT position transducer and servo-valve manifold into one compact, pre-adjusted package. Servo-
actuators can help reduce hydraulic installation time significantly and make calibration faster and easier.
There are a number of servo-actuators available with different specifications and mounting hardware, therefore no
specific information will be supplied in this document. Please contact Moog if more information is required on a
specific model or type.

1.6 Flushing.
Once all the hydraulic work has been completed you can start the process of flushing the hydraulic system. This
step is recommended to remove as much of the foreign matter left behind in the hydraulic system as possible
before installing the servo-valves.
It is also recommended that the system be flushed every time the reservoir is drained and refilled, a cylinder is
replaced, or a pump or any other major hydraulic component on the machine is replaced.
The first step in flushing is to remove the servo-valves from their manifolds or actuators and replace with the proper
flushing blocks. Install the flushing element in the high-pressure filter assembly and make sure the dirt alarm has
been properly reset. (Flushing elements are identified by a red band printed around the filter element.)
Jog the pumps to insure that there are no major leaks in the hydraulic system. If all looks tight start the pumps and
allow them to run. After a short run time carefully inspect all the hydraulic fittings and lines to insure there are no
leaks.
Periodically check the filter dirt alarm on the high-pressure filter to see if it has tripped. If it has, stop the pumps and
replace the flushing element with a new one. Reset the dirt alarm and restart the pumps. Allow them to run while
periodically inspecting the dirt alarm.
The system has been satisfactorily flushed when the pumps can run for two complete hours without tripping the
dirt alarm.
