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-

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

Maintenance 0001−1/A1

RT-flex50-D

Wärtsilä Switzerland 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!
