Preface

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

correctly 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 function 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 Operating 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:

1) General guidelines for maintenance

2) Clearance tables, tightening values of screwed connections, masses (weights)

3) Maintenance schedule

4) Design groups

5) Tool lists

A few explanations to the above:

1) The ’General Guidelines for Maintenance’ contain, in addition to

recommendations on precautionary measures to be taken, also suggestions for

carrying out the work.

2) The above mentioned tables inform about normal and maximum acceptable

clearances, the tightening of important screwed connections, weights of

individual engine components as well as the type and use of various sealing

rings.

3) The ’Maintenance Schedule’ indicates nominal intervals in which various

maintenance operations are to be carried out. Please note that the maintenance

intervals are based on experience and are subject to operation of the engine

under standard conditions.

4) Detailed instructions are given in the ’Design Groups’ on the procedure of

maintenance work on certain engine parts.

5) 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!
