About the Manual Section i - Introduction M11 Page i-2 About the Manual This M11 Shop Manual is intended to aid mechanics in disassembly, inspecting parts for reuse, rebuilding and assembly of components on M11 engines. The manual is divided into sections. Section 0 outlines the disassembly and assembly of the engine while the other sections detail specific components. How to Use the Manual This manual is divided in the same group system used for Cummins’ filmcard system. Each group is organized in a way that all mechanics, both those who are and are not familiar with the M11 engine models, can reference the manual.
Refer to the Table of Contents at the front of the manual to determine the group that details the desired information. Each group contains the following in sequence: Section contents at the beginning of each group to quickly aid in locating the information desired. Service tools list with recommended tools needed to rebuild the components. General information to aid in rebuilding the component, and an explanation of design change differences. Step-by-step rebuild instructions for disassemby, cleaning, inspection and assembly of the component. Symbols which represent the action outlined in the instructions.
The definitions of the symbols, listed in four languages (English, Spanish, French and German), appear on pages i-3 through i-6. Topics will be listed alphabetically on the ‘‘Section Contents’’ page. All procedures are described using the ‘‘text symbol picture’’ (TSP) format. In general, each component rebuild will be described through a 3-step sequence of: (1) cleaning and inspection for reuse; (2) rebuild; and (3) replacement. Reference numbers (procedure numbers) are assigned to each process. Reference numbers are constructed with a section number and a two-digit sequenced number. Both metric and U.S. customary values are used in this manual.
The metric value is listed first, followed by the U.S. customary in brackets. An example is 60°C [140°].
