DESCRIPTION
The information below is specific to the
ZF
Transmissions,
the
TRANSMISSION TROUBLESHOOTING SECfiON
applies to all models.
CONNECTION
OF
GEAR
BOX
WITH
PROPELLER
ZF
recommendS: 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.
A
CAUTION:
The
position
of
the
mechanism
behind
the
actuating
lever
is
factory-adjusted
to
ensure
equal
shift
lever
travel
from
neutral
position
ttl A
and
B.
If
this
mechanism
Is
in
any
way
tampered
with,
the
transmission
wa11anty
will
be
void.
"DRIVES AVER" is a product
of
Globe
Marine, 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, etr.
In
order
to
mount a
support bracket for shift cable
to
secure
to,
use the threaded
pillar nuts located
on
the transmission housing above
the
shift lever. Reier
to
the
model's 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.Smm.
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
Check for proper lever travel at least each
season.
