1.1 Introduction
1.1.1 CUSTOMER’S
RESPONSIBILITY
The Customer/Operator is responsi-
ble to perform the necessary safety
checks to ensure that lubrication, cool-
ing, maintenance and recommended
practices are strictly followed for safe,
enjoyable operation.
All Transmission units are covered by
a guarantee. Therefore: In respect to
the handling of the transmission units
the instructions stated in this manual
are to be strictly followed.
CAUTION
The manufacturer is not liable for
any damages or losses caused by
faulty installation, wrong handling
of the equipment and/or deficient
maintenance.
The Customer has to make sure,
that any external forces, as well
as vibration caused by torsion and
bending, are avoided.
The interaction between engine,
shaft and propeller may lead to
torsional vibration, producing a
hammering noise of gears and
might damage the engine and/or
transmission.
The Supplier is not liable for such
torsional vibration inherent to the
installation.
This manual includes, among others,
the following three main chapters:
1.1.2 DESCRIPTION
This part briefly describes function,
operation and design of the ZF/ZFE
types A/H/IV.
1.1.3 OPERATION
This part describes the procedures for
Operation and all necessary safety
measures.
1.1.4 MAINTENANCE
This part contains all maintenance and
service tasks to be performed by the
operator.
Whenever the terms «right, left, star-
board, port» are used in this manual,
they always refer to the installed
transmission in direction of forward
movement.
Important information related to tech-
nical reliability and operational safety
are highlighted by the identifying words
as follows:
WARNING
Any procedure, practice, condition,
statement etc., which is not strictly
followed, could result in injury or
death of personnel.
CAUTION
Any procedure, practice, condition,
statement etc., which is not strictly
followed, could result in damage or
destruction of equipment.
NOTE:
Applies to technical require-
ment to which the user of the equip-
ment must pay particular attention.
WARNING, CAUTION
and
NOTE
always precede the text to which they
apply.

3.1 Description
The ZF / ZFE A/H/IV marine trans-
mission is a hydraulically activated
helical gear unit, developed for use in
commercial and pleasurecraft and de-
signed as a three shaft type gearbox.
(Four shafts design for IV type).
The transmission is provided with a
disc-type reversing clutch mounted
on the input shaft and supplied with
hydraulic pressure from a fluid pump.
Operation of the fluid pump is depend
-
ent on the engine speed; the pump is
integrated in the control block.
The transmission is lubricated by
splash and force-feed lubrication.
3.1.1 ZFE OPTION
A head, astern, clutch disengagement
are operated electrically by ON/OFF
electric valves.
Electronic control block includes «get
home» features as well.
A simple mechanical device permits
manual engagement of the clutch.
