Introduction
THE MANUAL AND ITS ARRANGEMENT
This manual covers the basic 855 Cubic Inch
Displacement Engine Series built by Cummins Engine
Company, Inc., Columbus, Indiana and its subsidiaries.
These engines are used in many applications and have
gained world-wide recognition for their dependability and
simplicity of design.
Parts
Dimensions,
Wear
Limits
And
Torque
Specifications
An exploded view of components and pertinent
specifications are listed in a table at the beginning of
each Group.
Worn limits are listed where applicable.
Torque specifications are within the text or tabulated the
same as parts dimensions.
Near the end of the manual is Section 18, a complete
tabulation of parts dimensions, worn limits and torque
specifications.
Worn Limits
Worn limits, as stated in this manual, indicate that the
part may be reused if it is at the worn limit.
Discard only
if it exceeds the worn limit.
Of course, the reuse of any
part is partially the responsibility of the person making
the inspection, as it could well be damaged in an area
not listed as a worn limit, thus making it unfit for further
use.
Universal Units
Units such as fuel pumps, injectors, air compressors and
turbochargers are also used on other models of
Cummins Engines.
These group sections are in
separate manuals and written so they may be used with
other engine shop manuals, These units are covered in
full detail to make the information as useful and
universally applicable as possible.
Auxiliary Equipment
Units
such
as
hydraulic
governors,
exhaust
brakes,
thermatic fans, etc.
are sometimes used on Cummins
Engines.
These special units are listed in the group in
which they operate (hydraulic governors with Fuel Pump
Group, etc.), information not contained in this or separate
Cummins manuals must be obtained from the
manufacturer.
Service Tools
The average repair shop does not have all the factory
facilities to do machining; however, it must be equipped
with sufficient tooling to duplicate factory standards if the
rebuilt unit is to do a good job.
Cummins Service Tools identified by "ST" numbers are
listed at the beginning of each group and described as
those required and those which are desirable.
Procedures for use of those Service Tools that are most
difficult to use are described at the end of each group.
Cummins Service Tools may be ordered through
Cummins Distributors.
Additional Information
Cummins Engine Company, Inc.
is constantly improving
its products and Cummins Distributors and Dealers are
kept fully abreast of these improvements, and where
possible the instructions to apply the improvements to
engines already in service at the lowest possible cost to
the engine owner. Information on improvements and
changes are released and arranged using the group
number system so the Distributor or Dealer has a ready
cross reference between manuals, new information and
parts.
Complete new products as released will be
applied to the engine group within which it is used or, if
necessary, a new group will be established.
