DESCRIPTION
The information below
is
specific
to
the
ZF Transmissions,
the
TRANSMISSION
TROUBLESHOOTING
SECTION
applies
to
aU
models.
CONNECTION
OF
GEAR
BOX
WITH
PROPELLER
HEW
recommend
a flexible connection
between
the
transmission
gearbox and the propeller shaft
if
the
engine
is
flexibly
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
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
flexible
coupling
or
"DRIVESAVER"
will
reduce
stress
in
the
gearbox
bearings caused by hull distortions, especially
in
wooden
boats
or where the distance
between
transmission
output
flange
and
stem gland
is
less
than
about
800mm.

CAUTION:
The
position
of
the
mechanism
behind
the
actll6ting
lever
is
factory~adjusted
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.

is
a product of
Globe

Rockland,
MA.
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
housing.
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
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 right
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
actuating
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
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 lever
travel
at
least
each
season.
