SHAFT
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
manufacturers
instructions.
Even
with
the
engine solidly
mounted,
the
use
of
flexible
coupling or "DRNESAVER" will reduce stress in the gear-
box.

is
less than about 800mm.
NOTE:
When
installing
the
transmission,
make
cel1ain
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
suppon
for
shift control cable connections, use
the
two threaded holes located above
the
cable bracket mounted
on the gear housing. Refer
to
the WESTERBEKE parts
list.
SHIFT
LEVER
The
transmission
is
suitable
for
single
lever
remote
control.
Upon
loosening
the
retaining
screw,
the
actuating
lever
can
be
moved
to
any
position
required
for
the
control elements
(cable or rod linkage). Make certain that the shift lever does
not
contact
the
actuating
lever cover
plate:
the
minimum
distance between lever and cover should be O.5mm.
The control cable or
rod
should be arranged
at
light angle
to
the
actuating
shift lever
when
in
the
neutral
position. The
neutral position
of
the operating lever
on
the control console
should coincide with the neutral position
of
this lever.
The shifting travel,
as
measured at the pivot point
of
the actu-
ating lever, between the neutral position and end positions A
and B should be at least
35mm
for the outer and
30mm
for
the
inner
pivot
point.
A greater amount
of
shift 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.
1bis would
be
indicaled
by slow clutch engagement or no engagement at all.
NOTE
Check
for
proper lever travel at least each season.
