Hydraulic fittings and flexible
hoses |
To ease the installation we have available a range of
fixed length flexible hoses with 3/8" BSP ends. The available lengths
are 1, 2, 3, 5 and 8 metres. The connections on the pedestal are all
3/8" BSP. To connect the flexible hoses to the smaller cylinders you
need to use the converter fitting from 3/8" BSP to 1/4" BSP.

| The hydraulic pump in the pedestal is not equipped
with a lock valve (non-return valve). The consequence is that the rudder
pressure can be felt on the steering wheel, and when the helmsman
loosens the wheel, the wheel will rotate back to the mid position. When
this feature isn't appreciated, one should us a lock valve to prevent
oil to flow back to the pump.
When the hydraulic system is equipped with a second pump (for inside
steering) or a hydraulic autopilot drive one should always us a lock
valve between the pedestal and the rest of the hydraulic system. This
will force the oil to the cylinder and prevent it to take the easy route
to the pump and cause the wheel to rotate.
