ESCRIPTION
The 7065-SBXX cylinders are power-assist cylinders that are controlled via inputs from fluid
pressurized by a helm pump but are powered by a machine-driven pump. This configuration
enables responsive steering while requiring minimal human effort. In the case of a failure of
the machine-driven pump the unit automatically switches to manual mode which allows for
steering via helm pump pressure only. 7065-SB cylinders consist of three main subunits which
are the main cylinder, the control cylinder, and the valve and are identified in Figure 1 below.

This product comes in cylinder stroke configurations of 7.5, 10, 12, and 16 inches. Technical
specifications of the cylinder models can be found in Table 1 on page 6. Expected torque
values for 35° and 45° tillers can be found in Table 2.
Before ordering any steering system, it is required that a
steering gear torque and rudder calculation be done to ensure
the system is appropriately sized and the correct mix of
pressure, displacement, stroke, parts, and torque is selected.
