HYDRAULIC CONNECTIONS FOR TWO LINE STEERING SYSTEMS
A simple schematic of the pump installation is shown in Figure 2.
2 Line Steering System Installation
Delivery Lines:
Ports A and B in the diagram above are
the input/output ports of the pump and
must be connected to the steering lines
coming from the steering cylinder. It does
not matter which pump port is connected
to which steering line.
Compensating Line:
In the above diagram Port C is the
compensating or bleed line, and must be
connected to the steering system's
reservoir. This connection can be made
at a helm pump, remote reservoir (if there
is one), the compensating line connecting
two helm pumps, or the compensating
line connecting a helm pump to the
remote reservoir. If the connection is
being made directly to the helm pump,
ensure that the bleed line is connected to
the
LOWER
helm bleed port.
The compensating line MUST have a gradual rise from the pump to the connection to the
steering system. This allows air to rise out of the pump, ensuring a constant supply of oil to the
pump.
