Note on the Explanation Method of This Manual
The removal and installation of parts are for the most part illustrated by large and clear illustrations that should provide the
reader with visual aid in understanding the major point for servicing.
The system illustrations are augmented by callouts whose numbers or letters indicate the order in which the parts should
be removed or installed.
The sequence of steps represented numerically are differentiated from the ones represented alphabetically to notify the
reader that they must perform these steps seperately.
For example, if the steps prior and up to camshaft removal are performed with the engine installed, but the subsequent
steps like cylinder head removal require engine removal, the callouts are grouped in numerical and alphabetical orders.
The illustrations may contain symbol marks to indicate necessary service procedures and precautions that need to be
taken. Refer to the next page for the meaning of each symbol mark.
Also in the illustration is a chart that lists information such as the order in which the part is removed/installed, the name of
the part, and some extra notes that may be needed.
Step by step instructions are provided to supplement the illustrations when detailed explanation of the procedure is neces ­
sary or illustrations alone would not suffice.
Service procedures required before or after the procedure described on that particular page, or inspection/adjustment pro ­
cedures required following the installation of parts, are described under the title Requisite Service.
Standard workshop procedures and knowledge covered in the Common Service Manual are abbreviated in this manual.
