HBW
TRANSMISSION
INITIAL
OPERATION
All
HBW
marine transmissions are test-run on
dynamometer
with the
engine
at the factory prior to delivery.
For safety reasons the fluid is drained before shipment.
Fill the
gearbox
with Automatic Transmission Fluid
(DEXRON
II
or
DEXRON
III).
The
fluid level
should
be up
to the index mark on the dipstick. To check the fluid level,
just insert the dipstick, do not screw
it
in.
Screw the dipstick
into the case after the fluid level
is
checked, and tighten. Do
not forget the sealing ring
under
the hex head
of
the dipstick.
Check for leaks and change the fluid after the first 50 hours.

OPERATION
The neutral position of the operating lever on the control
console must coincide with the neutral position
of
the actuat-
ing lever on the transmission. Shifting
is
initiated
by
a cable
or rod linkage via the actuating lever and an actuating cam.
The completion of the gear changing operation
is
servo-auto-
matically controlled within the gear. Gear changing should be
smooth, not too slow, and continuous (without interruption).
Direct changes from forward to reverse
are
permissible, since
the multiple-disc clutch permits gear changing at high rpm,
including sudden reversing
at
top speeds
in
the event
of
danger.
WHEN
UNDER
SAIL
OR
BEING
TOWED
Rotation
of
the propeller without load such as when the boat
is
sailing, being towed, or anchored
in
a river, as well
as
operalion
of
the engine with the propeller stopped
(for
charg-
ing the battery), will have no detrimental effects on the
tranmission
NOTE:
When the boat is sailing (engine
ofJ),
the gear lever
can be set
in
the neutral
pOSition,
the propeller
(flOW
at idle)
can free
wheel without causing any problem.

Locking
the
Prop
If you prefer to lock the propeller when sailing. simply shift
into reverse. Do not shift into forward gear. (Locking the
propeller shaft
by
an
additional hrakc
is
unnecessary). Return
the shift lever to neutral before starting the engine.

WARNING:
00
not
start
the
engine
with
the
transmission
in
gear.
Always
return
the
shift
lever
tooneutral!
CONTROL
CABLES
The transmission is suitable for single lever remote control.
Upon loosening the retaining screw, the shift lever can be
moved to any position required for the
control elements
(cable or
rod
linkage). Make certain that the shift lever docs
not contact the shift lever cover plate: the minimum distance
between lever and cover should be
O.5mm.
The control cable or rod should be arranged at a right angle
to the 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 the shift lever on the
gear box.
The shifting travel,
a<;
measured at the pivot point
of
the
shift
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 detrimen-
tal, and
is
recommended. However, if the shift lever travel is
shorter, proper
dutch
engagement might be impeded which,
in
tum, would mean premature wear. excessive heat genera-
tion and clutch plate failure. This would be indicated
by
slow
clutch engagement or no engagement
at
all.
NOTE:
Check
jor
proper shift lever travel at least each season.
