1. General
The Spare Parts Catalogue is individually collated and specific for the installation and
engine number(s) stated in the flyleaf of this catalogue.
When compiling this Spare Parts Catalogue the demands for interchangeability
as well as former experiences of adaptability have been considered. Simple
components are normally supplied as complete units. However, details exposed to
wear may be supplied separately.
The customer will get information about prospective modifications and changes in the
specifications when needed through the Service Bulletins. When modifications are
made into the engine by the customer, the nearest Wärtsilä Service Office must
always be informed about the changes in order to update the spare parts database etc.,
see section 5, Updating of the Spare Parts Catalogue.
Regarding spare parts for some of the sub suppliers components, e.g. governor, we
refer to lists in the special instructions enclosed the documentation set. Tools needed
for repair or maintenance of the engine and special equipment are to be found in the
Instruction Manual for this engine.
Concerning the terminology used, see installation specific Instruction Manual.
Wärtsilä is continuously developing the products and reserves all rights to make
technical changes and modifications without any notification in advance.
2. Table of Contents and Alphabetical Index
The Spare Parts Catalogue contains a Table of Contents and an Alphabetical Index.
The Table of Contents the sections are in section number order and in the
Alphabetical Index in section name order.
3. Spare Parts Sections and Interleaves
3.1 General
The Spare Parts Catalogue is divided into 15 chapters according to contents by using
interleaves. Chapters are further divided into “Sections” to offer a detailed view of
parts needed. A section can contain one or several pages, which are numbered 1, 2, 3
etc. The section number is located on the right side of the headline. A section number
is build up of a three digit main group number and a two to four digit running
number, e.g. 100-0002.
For a specific engine the section numbers will not be consecutive.
Note! The format and location of the section number, page number and edition may
vary in older sections between different engine types due to modification of the
layout and content.
