various aircraft, model numbers will be used in this publication unless names
are required todifferentiate
between versions of the same basic model. The following table provides
a cross reference listing of popular

FOREWORD
This manual contains factory recommended procedures and
instructions for ground handling, servicing and maintaining
Cessna Model 172-Series aircraft. This includes the Models
172, Skyhawk, Reims 172 and Reims/Cessna F172. The Reims
versions
of the Model 172 and Skyhawk are identical to the Model
172 and Skyhawk, through Model year 1971, except that they
are
powered by 0-300-D Rolls Royce engines. Beginning with the
1972 Models, both 172 and F172-Series aircraft
are powered by
"Blue- Streak" (Lycoming) engines. Besides serving
as a refer-
ence for the experienced mechanic, this manual also covers
step-by-step procedures for the
less experienced man. This
manual should
be kept in a handy place for ready reference. If
properly used,
it will better enable the mechanic to maintain
Cessna 172-
Series aircraft and thereby establish a reputation
for
reliable service.
The information in this manual
is based on data available at
the time of publication, and
is supplemented and kept current
by service letters and service news letters published by Cessna
Aircraft Company. These
are sent to all Cessna Dealers so that
they have the latest authoritative recommendations for servicing
Cessna aircraft. Therefore, it
is recommended that Cessna owners
utilize the knowledge and experience
of the factory-trained Dealer
Service Organization.
In addition to the information in this Service Manual,
a group
of Vendor publications
is available from the Cessna Service Parts
Center which describe complete disassembly, overhaul, and parts
breakdown
of some of the various vendor equipment items. A listing
of the available publications
is issued periodically in service letters.
Information for Nav-0-Matic Autopilots, Electronic Communi-
cations, and Navigation Equipment
are not included in this manual.
These manuals
are available from the Cessna Service Parts Center.
