TRANSMISSION
TROUBLESHOOTING
SECTION
applies
to
all
models.
CONNECTION
OF
GEAR
BOX
WITH
PROPELLER
HBW 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,
proyided
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 "ORNESAVER" will reduce
stress
in the
gearbox
bearings
caused
by bull distortions, especially
in
wooden boats or
where
the distance between transmission .
output
flange
and stem
gland
is less
.than
about
800mm.
INCLINATION
A
CAUTION:
The
position
of
the
mechanism
behInd
the
actuating
lever
is
factory-adjusted
to
ensure
equal
shift
lever
travel
from
neutral
position
to
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
OJ
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 0.5mrn.
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
sbould 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
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.
NOTE
Check
for proper
leve
r
travel
at
least
each
season.
