HOW TO USE THE MANUAL
Caterpillar Manuals include illustrations of the groups or assemblies which make up the machine. These illustrations show the standard
components plus many of the attachments available for the machine.

The alphabetical index located in the front part of the book should be used to determine the page number on which specific illustrations are shown.
Reference to those pages will identify each of the individual serviceable parts.

Captions
The caption under each illustration identifies the part number and name of the group or assembly shown. If more than one illustration is included for
any group, the caption identifies the specific machine serial numbers to which each illustration applies.

In some cases, it is not possible to determine the specific machine serial numbers to which different illustrations are applicable. In those cases, the caption identifies the illustration as “First Type”, “Second Type”, etc. Reference to the actual group or assembly is necessary in those cases to determine which illustration should be used.

Captions provide additional information such as page numbers where illustrations of sub-assemblies are shown, information regarding
quantities used and other information intended to assist the user in determining parts needs.

This information indicates the effective serial number or effective date on which changes became effective.

Continuing improvement and advancement of product design may cause changes to your machine which may not be included in this publication. Each publication is reviewed and revised, as required, to update and include these changes in later editions.

Whenever a question arises regarding your Caterpillar product or this publication, please consult your Caterpillar dealer for the latest available information.
