A
CAUTION:
The
position
of
the
cover
plate
underneath
the
actuating
lever
is
factory-adjusted
to
ensure
equal
shift
lever
travel
from
neutral
position
to
A
and
B.
If
this
side
shift
cover
is
removed
or
in
any
way
tampered
with,
the
transmission
warranty
will
be
void.
Authorized
Hurth
personnel
only
may
adjust
or
remove
this
cover.
NOTE:
When installing the gearbox, 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.
MAINTENANCE
Transmission
Fluid
To ensure trouble-free operation
of
the gearbox, only
use Automatic Transmission Fluid (ATF), (Dexron II
or
Ill).
Capacity
Add the fluid quantity for the proper model transmission
to the gearbox. After filling, check the fluid level with
the dipstick. Adjust level as needed. Install the dipstick
with the sealing washer, operate unit, check fluid, check
for leaks.

Fluid
Change
Change the fluid for the first time after about 50 hours
of
operation, then every 250 operating hours
or
at least once
a year
or
when you change engine oil. When changing
the fluid, also check the gearbox cooling device and
clean or replace it as necessary.
NOTE:
When changing the fluid, take care not to lose the
drain plug sealing washer. The drain plug will leak with-
out this sealing washer.
Checking
the
Bowden
Cable
or
Rod
Linkage
The Bowden cable
or
rod linkage should be checked at
regular intervals. Check the neutral position
of
the operat-
ing lever (on the control console) and the actuating lever
(on the gearbox). The minimum lever travel from the
neutral position to the operating positions (0 - A = 0 - B)
should be 35mm for the outer and 30mm for the inner
pivot point. Make certain that these minimum values are
safely reached. Check the cable
or
rod linkage for easy
movability
a~d
proper attachment.
Connection
of
Gearbox
with
Propeller
HBW recommends a flexible connection between the
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
manufacturer's instructions.
Even with the engine solidly mounted, the use
of
a flexi-
ble coupling reduces stresses in the gearbox bearings
caused by hull distortions, especially in wooden boats
or
where the distance between the gearbox output flange
and the stem gland is less than about 800mm.
Lay-up/Winterize
If
the transmission is not used for periods
of
more than
one year, it should be completely filled with fluid
of
the
same grade to prevent corrosion. Protect the input shaft
and the output flange by means
of
an anticorrosive coat-
ing, as required.
