Repair Instructions
The work methods described in the Workshop Manual
are applicable for a workshop environment. The drive
has removed from the boat and is installed in an
overhaul fixture. Unless otherwise stated recondition-
ing work which can be carried out with the drive in
place follows the same working method.
The warning symbols used in the Workshop Manual
(see Safety Information for implication),
WARNING!
IMPORTANT!
NOTE! By no means cover everything since the
service work is conducted under a wide range of dif-
ferent conditions, and it is obviously impossible to
foresee everything. All that can be done is to point
out the risks that can occur from incorrect handling
when working in a well-equipped workshop with work
methods and tools approved by Volvo Penta.
Where Volvo Penta special tools can be used for
work procedures, these are described in the Work-
shop Manual. The object of special tools is to ensure
the safest and most rational work method possible. If
other tools or work methods are used than those rec-
ommended by Volvo Penta, then it is incumbent on
the person using them to ensure that there is no risk
of personal injury, damage, or malfunction.
In some cases, there are special directions and user
instructions for the tools and chemicals named in the
Workshop Manual. These directions should always
be followed even if there is no special mention of
them in the Workshop Manual.
Most risks can be prevented by means of taking ele-
mentary precautions and using common sense. A
clean workplace and a clean drive will eliminate
many risks of both personal injury and drive malfunc-
tion.
Above all when working with bearing unions and
sealing unions, it is extremely important to prevent
dirt or foreign objects from getting in, since this can
result in malfunction or reduce the life span of the re-
pair.
Our joint responsibility
Every engine consists of a large number of co-ordinat-
ed systems and components. The deviation of one
component from the technical specification can dra-
matically increase the impact on the environment from
what is otherwise a good engine. It is therefore ex-
tremely important to maintain the given tolerances, to
implement the correct adjustments where applicable,
and to use Volvo Penta Genuine Parts. The time
schedule in the engine’s maintenance schedule must
be followed.
Certain systems, e.g. components in the fuel system,
may require special competence and special testing
equipment. For environmental reasons certain com-
ponents are sealed at the factory and must not be
worked on by unauthorised persons.
Remember that most chemical products when incor-
rectly used can be damaging to the environment.
Volvo Penta recommends the used of biologically de-
composing degreasing agents for all cleaning of en-
gine components, unless otherwise stated in the
Workshop Manual. When working onboard boats
special care must be observed to prevent oils and
suds etc. unintentionally ending up the nature, e.g.
via the bilge water.
Tightening torques
Tightening torque for vital unions, which should be
tightened with a torque multiplier, are indicated in the
Workshop Manual,
Technical data, Tightening tor-
ques and the manual’s work descriptions. All torque
readings are applicable for clean threads, screw
heads and mating surfaces. The torque readings re-
fer to lightly oiled or dry thread. If lubricants, locking
fluids or sealant are required for screw union, then
the type is indicated in the work description. For un-
ions where special torque denotations are not indi-
cated, the general tightening torque is applicable ac-
cording to the table below. The torque readings are
guide values, and unions do not need to be tightened
with a torque multiplier.
