5.2.5 Mounting a Ram on a Vertical Bulkhead
Due to the restricted movement of the ram of +14
o
, -10
o
for the
Type 0, 1 and 2 and +/- 5
o
for the Type 3, it is important that the
maximum rudder angle is carefully measured and the positioning
of the ram, tiller arm length and offset are carefully followed as
shown in Figure 5.7.
CAUTION: Failure to comply with these dimensions may
cause premature failure of the ram and place excessive stress
on the structure of the vessel.
The Type 0, 1 and 2 Rams may be mounted in any orientation,
without the need to fit an external reservoir. The Type 3 Ram
requires an external reservoir that must be mounted above the unit
and care must be taken to ensure that the connecting pipes are
not in any way kinked or turned through any tight bends.
5.2.6 Splitting the Ram Drive Unit
Important Note
When dealing with any hydraulic system great care must be taken
to ensure that a high degree of cleanliness is observed and no dirt,
moisture or foreign objects are allowed to enter the system. Only
the recommended fluids must be used:
Use only Q8 DYNOBEAR 10 or equivalent (10cSt at 40°C).
It is not possible to split linear actuators.
Type 1 and Type 2 units comprising separate ram/pumps,
reservoirs and hydraulic cylinders connected by hoses, are
available from your dealer. These are supplied with 1-metre hoses.
Units with longer hoses are available from your dealer. These can
be supplied with quick connect couplings and pre-filled hoses.
Such units do not need to be bled.

hoses. Units with longer hoses are available from your dealer.
These can be supplied with quick connect couplings and pre-filled
hoses. Such units do not need to be bled.
