HURTH ifBWJZF TRANSMISSIONS
DESCRIPTION
The infonnation below is specific to the
Haw
Transmissions, the TRANSMISSION TROUBLESHOOTING
SECTION applies to all models.
INCLINATION
A
CAUTION:
The position of the mechanism behind
the actuating lever Is factory-adjust(ld to ensure equal
shift lever travel from neutral positio'; A and·B.
If
this mechanism Is in any way tampered with, the
transmisSion warranty wili be void.
SHAFT COUPLINGS
WESTERBEKE recommends a flexible connection between
the transmission and the propeller shaft if the engine is flexi-
bly 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 absorbed by the
transmission bearing, provided the value specified under .
SPECIFICATIONS is not exceeded. However, the output
shaft should be protected
from
additional loads. S,pecial care
should be taken to prevent torsionpi vibratipn. 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

reduce stress in the gear:.
box bearings caused by hull distortions, esp,cially in wooden
boats or where the distance between transmission output
flange and stem gland is less than about
800mm.
NOTE:
When installing
the
transmission, make certain that
shifting is not impeded by restricted movability of the· cable
or rod linkage, by unsuitably positioned guide sheaves, too
small a bending radius or other restrictions. In order to
mount a support for shift control cable connections, use the
two threaded holes located above the cable bracket mounted
on the gear housing. Refer to the WESTERBEKE parts list.
SHIFT LEVER
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 elemelllS
(cable or rod linkage). Milke certain that the shift lever does
not contact the actuating lever cover plate: the minimum
distimce between lever and cover should be O.5mm.
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 o.f the actu-
ating lever, between the neutral position and eM 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 trayel 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, ex.cessive heat
generation arid 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.
