HBW
recommend
a
flexible
connection
between the
trans-
mission
gearbox
and
the
propener
shaft
if
the engine
is
flexibly
mounted,
in
order
to
compensate
for
angular
deflections.
The installation of a
special
propener thrust
bear-
ing
is
not
required,
since
the
propener thrust
will
be
taken
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 a
flexible
coupling

especially in
wooden

or
where
the
distance
between transmission output

and

is
less
than
about

A
CAUTION:
The
position
of
the
mechanism
behind
the
actuating
lever
is
fa&tory-adjusfed
to
ensure
equal
shift
lever
travel
from
neutral
position
A
and
B.
If
this
mechanism
is
In
any
way
tampered
with,
the
transmission
warranty
will
be
void.
NOTE:
When
installing
the
transmission,
make
certain
that
shifting is
not
impeded
by
restricted
movability
of
the
Bowden
cable
or
rod
linkage,
by
unsuitably
positioned
guide
sheaves,
too
small
a
bending
radius,
etc.
In
order
to
mount
a
support for
shift
control
cable
connections,
use
the
two
threaded
holes
located
above
the
shift
cover
on
top
of
the
gear
hausing.
Refer
to
the
WESTERBEKE
parts
list.
CONTROL
CABLES
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
shift
control
elements
(cable
or
rod
linkage).
Make
certain that
the
actuating
lever
does
not contact
the
actuating
lever
cover
plate:
the
minimum
distance
l)etween
lever
and
cover
should
be'O.5mm.
The
control
cable
should
be
arranged
at a right
angle
to
the
actuating
lever
when
in
the
neutral
position.
The
neutral
posi-
tion
of
the
shift
operating lever
on
the
control
console
should
coincide
with
the
neutral
position
of
the
actuating
lever.
The shifting
travel,
as
measured
at
the
pivot point of
the
actuating
lever,
between
the
neutral
position
and
end
positions A
and
B should
be
at
least
35mm
for
the
outer
pivot
point
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
tum,
would
mean
premature
wear,
excessive
heat
generation
and
clutch
plate
failure.
This
would
be
indicated
by
slow
clutch
engagement
or
no
engagement
at
all.
NOTE
Checkfor proper
actuating
lever
travel
at
least
each
season.
