Introduction
The working methods described in the Workshop
Manual apply to work carried out in a workshop.
The engine has been removed and is installed in
an engine fixture.
Unless otherwise stated reconditioning work that
can be carried out with the engine in place follows
the same working method.
All operations described in the Workshop Manual for
which there are Volvo Penta Special Tools available
assume that the service technician or person carrying
out the repair uses these tools.
Volvo Penta Special Tools have been specifically de-
veloped to ensure as safe and rational working met-
hods as possible.
Person or persons using other than Volvo Penta Spe-
cial Tools or approved Volvo Penta working methods
(as described in a Workshop Manual or Service Bulle-
tin). Has the responsibility to acquaint themselves of
the risk of personal injury or actual mechanical dama-
ge or malfunction.
In some cases special safety precautions and user in-
structions may be required in order to use the tools
and chemicals mentioned in the Workshop Manual, al-
ways follow these precautions, as there are no speci-
fic instructions given in the Workshop Manual.
By following these basic recommendations and using
common sense it is possible, to avoid most of the
risks involved in the work. A clean work place and a
clean engine will eliminate many risks of personal inju-
ry and engine malfunction.
Above all when working on the fuel system, lubrication
system, intake system, turbocharger, bearings and
seals. It is extremely important to observe the highest
standards of cleanliness and avoid dirt or foreign ob-
jects entering the parts or systems, since this can re-
sult in reduced service life or malfunctions.
Our joint responsibility
Every engine consists of many systems and compo-
nents that work together. If one component deviates
from the technical specifications, than this can have
dramatic consequences on the environmental impact,
even if it is otherwise in good running order.
It is therefore critical that the stated wear tolerances
are observed, that systems which can be adjusted are
correctly set up and that only Volvo Penta Original
Parts are used.
The stated service intervals in the Maintenance Sche-
dule must be followed.
Some systems, such as the components in the fuel
system, require special expertise and special testing
equipment for service and maintenance.
Some components are factory sealed for environ-men-
tal and product specific reasons. Don’t under no cir-
cumstances attempt to service or repair a sealed co-
mponent, unless it is done by a authorized service te-
chnician.
Bear in mind that most chemical products, incorrectly
used, are hazardous to the environment.
AB Volvo Penta recommends the use of biodegrada-
ble degreasing agents for all cleaning of engine com-
ponents, unless otherwise is stated in the Workshop
Manual.
Pay special attention to make sure that oils and wash-
ing residue are handled correctly for destruction, and
not end up in the nature.
