Preface - Mercedes-Benz OM 651 Service Manual

Dear Reader,
This Introduction into Service Manual presents the
new 4-cylinder inline diesel engine 651 from
Mercedes-Benz.
It allows you to familiarize yourself with the technical
highlights of this new engine in advance of its market
launch. This brochure primarily intended to provide
information for people employed in service, mainte-
nance and repair as well as for aftersales staff. It is
assumed that the reader is already familiar with the
Mercedes-Benz model series and major assemblies
currently on the market.
In terms of the contents, the emphasis in this Intro-
duction into Service Manual is on presenting new and
modified components, systems, system components
and their functions.
This Introduction into Service Manual aims to provide
an overview of the technical innovations and an insight
into their complicated designs.

However, this Introduction into Service Manual is not
intended as a basis for repair work or technical diag-
nosis. For such needs, more extensive information is
available in the Workshop Information System (WIS)
and in the Diagnosis Assistance System (DAS).
WIS is updated monthly. Therefore, the information
available there reflects the latest technical status of
our vehicles.
The contents of this brochure are not updated and no
provision is made for supplements. We will publicize
modifications and new features in the relevant WIS
documents. The information presented in this Intro-
duction into Service manual may therefore differ from
the more up-to-date information found in the WIS.
All information relating to technical data, equipment
and options is valid as of the copy deadline in July 2008
and may therefore differ from the current production
configuration.
