DESCRIPTION
The information below
is
specific to the
ZF
Trans~issions,
the TRANSMISSION TROUBLESHOOTING SECTION
applies to all models.
CONNECTION
OF
GEAR
BOX
WITH
PROPELLER
ZF recommends a flexible connection between the ·
transmission gearbox and the ·propeiiershattTfthe 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
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
of
the
Bowden cable
or
rod linkage, by unsuitably positioned guide
sheaves, too small a bending radius, etc. In order
to
mount a
support
bracfcet
for
shift cable to secure
to,
use the threaded
pillar nuts
located
o~
the transmission housing above the
shift lever. Refer 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
0.5mm.
TI1e
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 8 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
ail.
NOTE
Check
for
proper lever travel
at
least each season.
