About the Manual
This manual contains information for 1991 and newer engines starting with ESN 44566920. For information on prior
built engines refer to the B Series Shop Manual, Bulletin No. 3810206-02.
The procedures in this manual were developed for a shop environment with engine disassembly and assembly
being performed on a rollover stand. A Group System has been used to subdivide the instructions by major
components and systems. Refer to the Table of Contents (page i-1) for the various groups. The information is
presented in very basic terms to make sure the instructions are easily understood. Wrench sizes and shop tooling
are identified in the procedure when needed.
Each group contains the following in sequence:
An Alphabetical Table of Contents (Index).
Exploded view(s) of all the components in the group.
General Information Section(s) containing the basic service, maintenance, and design information
necessary to assist in the rebuild of the engine or a component.
Procedural instructions for the disassembly, inspection, repair, and assembly that can be required to
rebuild an engine. Additional repairs that are not essential during every rebuild, but can be necessary,
are included. These repairs depend on the length of time an engine has been in service and the condition
of the parts.
