Drive Installation; Removing Existing Steering Helm - Simrad AP14 Manual

5 Installation - AP14R
Section 5 covers the installation of the AP14R
Rotary drive version only. Please refer to sec-
tion 4 for AP14H Hydraulic version installa-
tion instructions.

5.1 Drive Installation

The SRD12 drive is a combined steering helm
and gearbox which completely replaces the
existing steering helm unit (Fig 5.1).
The drive unit is based on the popular Morse
CMD290 helm unit and is directly compatible
with this.
• The drive can also be fitted onto boats using
other systems including Teleflex, Uflex, Acco,
Mercury, Volvo Penta, Detmar, rack and pinion
etc. Depending on the system, it may be neces-
sary to fit an adaptor or change the cable and
dashboard bezel kit. Refer to the table below
for more details. All codes quoted are Morse
part numbers and are available from Morse
suppliers.

To be able to fit the AP14R to the boat, the fol-
lowing basic requirements must be met -
1. The boat must have at least one single cable
steering helm. Dual cable systems, which are
for high performance boats or boats over 11m
(35 Ft) cannot be adapted for the AP14R.
However, the AP14R can be fitted to boats with
two steering positions, providing that one has a
single cable helm.
2. There must be a minimum of 250mm (10.0 in)
clearance behind the dashboard for the drive
unit to fit (Fig 5.2).
• If the boat has a Morse CMD290 helm system
fitted, it can be directly replaced with the
SRD12 drive unit.
• Other rotary helm units may need a cable
adaptor, dashboard bezel kit, or the whole
steering cable may need to be replaced (see
compatibility guide, page 21).
• On boats with rack and pinion steering it will
be necessary to change the steering cable.
• ACCO or Mercury steering systems will also
need to change the steering wheel for one with
a 18.75mm ( 3 ⁄ in) shaft aperture.

5.2 Removing Existing Steering Helm

To remove the existing steering helm, take the
steering wheel off then unbolt and remove the
helm unit. If it is a rack and pinion system then
NO
the rack will need to be unbolted from the pin-
NO
ion before it can be removed.
Check that there is enough clearance behind the
dashboard for the drive unit before installing -
NO
obstructions such as electrical wiring and throt-
tle cables may need to be re-routed.
NO
If a bezel kit is needed, note the angle that the
NO
helm is mounted to the dashboard. Bezel kits
are available either in the standard 90º configu-
NO
ration, or 20º if the helm is fitted at an angle to
the dashboard (Fig 5.3). Note that tilting wheel
systems use the existing (original) bezel kit.
