ticularly the copyright, remains with Wärtsilä Switzerland Ltd. This document
and parts thereof must not be reproduced or copied without their written permis-

any unauthorized purpose.
Before the operator intends to use the engine or before maintenance work is un-
dertaken, the Operating Instructions or the Maintenance Manual respectively is to
be read carefully.
To ensure the best efficiency, reliability and lifetime of the engine and its compo-
nents, only original spare parts should be used.
It is to be ensured as well that all equipment and tools for maintenance are in good
condition.
The extent of any supplies and services is determined exclusively by the relevant
supply contract.
The data, instructions and graphical illustrations etc. in this manual are based on
drawings made by Wärtsilä Switzerland Ltd and correspond to the actual stan-
dard at the time of printing (year of printing is indicated on title page).
Those specifications and recommendations of the classification societies which
are essential for the design have been considered therein. It must be recognized
that such data, instructions and graphical illustrations may be subject to changes
due to further development, widened experience or any other reason.
This manual is primarily intended for use by the engine operating and maintenance
personnel. It must be ensured that it will always be at the disposal of such person-
nel for the operation of the engines and/or for the required maintenance work.
This manual has been prepared on the assumption that operation and mainte-
nance of the engines concerned will always be carried out by qualified personnel
having the special knowledge, training and qualifications needed to handle in a
workman-like manner diesel engines of the corresponding size, the associated
auxiliary equipment, as well as fuel and other operating media.
Therefore, generally applicable rules, which may also concern such items as
protection against danger, are specified in this manual in exceptional cases only.
It must be made sure that the operating and maintenance personnel are familiar
with the rules concerned.
This manual has been prepared to the best knowledge and ability of its au-
thors. However, neither Wärtsilä Switzerland Ltd nor their employees as-

Maintenance 0001−1/A1
RT-flex58T-D
Winterthur Gas & Diesel Ltd. 1/ 1
The instructions contained in this ”Maintenance Manual” are intended to help to
ensure that the maintenance which must be carried out at specific intervals is cor-
rectly carried out.
It is a precondition that the personnel charged with such important work possesses
the necessary training and experience.
Information about the operation of the engine as well as descriptions of the func-
tion of the various systems are part of a separate book, the ”Operating Manual”
containing also under 0010−1 explanations of the layout and structure of the Oper-
ating and Maintenance Manuals as well as of the used symbols, signs and special
characters.
More detailed instructions on the operation and maintenance of components from
sub-suppliers can be gathered from the instruction leaflets of the respective
manufacturers. Outside makes are, for example, such engine components, tools
or devices which are not manufactured in accordance with production drawings
from Wärtsilä Switzerland Ltd.
The ”Maintenance Manual” is divided into the following main chapters:
−General guidelines for maintenance
−Clearance tables, tightening values of screwed connections, masses
(weights), seal rings
−Maintenance schedule
−Design groups
−Tool lists
A few explanations to the above:
−The ’General Guidelines for Maintenance’ contain, in addition to recommen-
dations on precautionary measures to be taken, also suggestions for carrying
out the work.
−The above mentioned tables inform about normal and maximum acceptable
clearances, the tightening of important screwed connections, weights of indi-
vidual engine components as well as the type and use of various sealing rings.
−The ’Maintenance Schedule’ indicates nominal intervals in which various
maintenance operations are to be carried out. Please note that the mainte-
nance intervals are based on experience and are subject to operation of the
engine under standard conditions.
−Detailed instructions are given in the ’Design Groups’ on the procedure of
maintenance work on certain engine parts.
−Tools and devices necessary to carry out maintenance are described in the
’Tool Lists’, and are generally supplied with the engine.
All information contained in the text and illustrations of this manual are valid at the
time of printing.
Modifications will be incorporated in the next edition!
