INTRODUCTION
ABOUT THIS MANUAL
Changes from the Existing E-Tech™
Service Procedures Manual
Mack Trucks, Inc. has made many major
improvements to this E-Tech™ Service
Procedures Manual, with changes to both content
and organization. This is a complete manual,
describing engine features and the operation of
major systems as well as providing
comprehensive overhaul procedures,
specifications and adjustments.
All specifications and torque values are given in
English and metric measurements. Critical torque
values are also included in the text, eliminating
the need to refer to SPECIFICATIONS section
each time a specified torque value is required.
The Special Tools list has been revised to include
all special tools required for a complete overhaul.
Warnings, cautions, notes and service hints help
the technician service the engine safely and
efficiently.
The engine disassembly procedures show how to
remove components in an order that requires the
least amount of handling. Where appropriate, it
includes general information needed to properly
service that component.
Various component bench procedures guide the
technician in disassembly, cleaning, inspection
and assembly of each component. Each bench
procedure helps in determining if the part is
serviceable or should be replaced.
The engine reassembly procedure includes step-
by-step instructions for reassembling the engine.
This helps to ensure proper installation and
longer service life.
Under Engine Setup and Adjustments, the latest
setup information is provided for adjusting all
E-Tech™ engine models. Engines perform best
and conserve fuel most efficiently when adjusted
properly.
Two additional procedures are included as guides
for removing and reinstalling the engine. Both
sections are generic in nature since E-Tech™
engine installation procedures vary from one
vehicle style to another. As such, the procedures
are intended as a checklist to remind the
technician of all necessary tasks.
While troubleshooting procedures are similar for
most diesel engines, this manual includes only
those that pertain to the E-Tech™ engine. The
TROUBLESHOOTING section contains
symptom-related questions as well as tests to
help the technician consider all possible problem
sources.
This service manual also includes applicable
information from active service bulletins and
service letters since publication of the E-Tech™
Service Procedures Manual dated July 1999.
