media (oil, water and fuel) and descriptions of the components and systems. The
manual also gives troubleshooting procedures.
1.2 Maintenance Manual
The maintenance manual contains data about disassembly / assembly procedures
that are necessary for the engine maintenance and the maintenance schedule. This
manual gives more data about the masses (weight) of components, a clearance table,
tightening values for important screw connections and a tool list.
1.3 Code Book (spare parts catalogue)
In the code book all parts of the engine are marked with a unique code number. The
code number is necessary to order spare parts from Wärtsilä Services Switzerland
Ltd. or the engine supplier. The spare parts can only be ordered with the code
number from the code book.
1.4 External Supplier Documentation
The documentation from external suppliers gives data about the parts of the engine
that are not supplied by Winterthur Gas & Diesel Ltd. or Wärtsilä Services Switzerland
Ltd., such as turbocharger, automatic filter, torsional or vibration damper. Most of this

1.5 Records and Drawings
The setting tables, shop trial documents, schematic diagrams and survey certificates
of the related engine are given with the first supply of the documentation.
2. Manual Structure
The manual is divided into different groups. Each group contains data about
components or systems referred to in the design groups.
The manuals give data about the standard engine with all cylinder numbers,
alternative designs and special equipment.
The documentation for alternative engine designs are separated into different
chapters with the related design name.
