CONNECTIONS
. The transmission is suitable for a single lever gear shift.
Upon loosening the retaining screw, the actuating lever (see
illustration) can be moved to any position required for the
control elements (cable or rod linkage). Make certain that the
actuating lever does not contact the lever hub: the minimum
distance between the lever and
hub
should be 0.02in(0.5mm).
The control cable
or
rod should
be
arranged at a right angle
to
the actuating lever when in the neutral position. The neu-
tral position
of
the gear shift lever
on
the control console
should coincide with the neutral position
of
the lever on the
transmission.
Shifting
Positions:
A= Propeller rotation opposite
of
engine rotation.
N= Neutral position
B=
Propeller rotation same as engine rotation.
NOTE:
When shifting to
"A"
or
"B"
positions. make sure the
shift lever travel is sufficient
for
the actuating lever to contact
its stop.

A greater amount
of
actuating lever travel is in no way
detrimental and is recommended. However,
if
the lever travel
is shorter, proper clutch engagement might be impeded
which,
in
turn, would mean premature wear, excessive heat
generation and clutch plate failure. This would be indicated
by slow clutch engagement or
no
engagement at all (see
CONTROL
CABLES
under TRANSMISSION

NOTE:
Check
for
proper actuating lever travel
at
least each
season.

SHAn
COUPLINGS
WESTERBEKE recommends a flexible connection between
the transmission and the propeller shaft
if
the engine
is
flexi-
bly mounted, in order to compensate for angular deflections.
The installation
of
a special propeller thrust bearing
is
not
required, since the propeller thrust will be absorbed
by
the
transmission bearing, provided the value specified under
SPECIFICATIONS is not exceeded. However, the output
shaft should be protected from additional loads. Special care
should be taken to prevent torsional vibration. When using a
universal joint shaft, make certain to observe the manufac-
turer's instructions.
Even with the engine solidly mounted,the use
of
a flexible
coupling
or
"DRIVESAVER" will reduce stress
in
the gearbox
bearings caused by hull distortions, especially
in
wooden
boats
or
where the distance between the transmission output
coupling and stern gland is less than about
800mm.
NOTE:
When installing the transmission, make certain that
shifting is
not
impeded
by
restricted movability
of
the cable
or
rod linkage, by unsuitably positioned guide sheaves, too
small a bending radius
or
other
restrictions.
In
order to
mount
a support
for
shift control cable connections, use the
two threaded holes located
on
the cable bracket mounted
011
the gear housing. Refer to the WESTERBEKE parts
list.
