EXPLANATION OF NUMERICAL CODE
EXPLANATION OF 3-DIGIT
NUMERICAL CODE
The organization of MACK service manuals has
been upgraded to standardize manual content
according to a reference system based on
component identification. The new reference
system will help link the information contained in
this publication with related information included
in other MACK service/warranty publications,
such as associated service bulletins, warranty
manuals, and the TS477 Service Labor Time
Standards Manual.
The system is based on a numerical code
first digit of which identifies the general
component grouping as listed here:
GROUP 000 — INSPECTIONS
GROUP 100 — CHASSIS
GROUP 200 — ENGINE
GROUP 300 — CLUTCH, TRANSMISSION,
TRANSFER CASE AND PTO
, the
GROUP 400 — STEERING, AXLES, WHEELS
AND TIRES, DRIVELINE
GROUP 500 — BRAKES, AUXILIARY
SYSTEMS
GROUP 600 — CAB, TRUCK BODY
GROUP 700 — ELECTRICAL
The second two digits of the 3-digit code
are used to identify the system, assembly or
subassembly, as appropriate, within each of
the groupings. The codes applicable to this
publication are shown at the TOP OF EACH
PAGE and at SECTION HEADINGS, as
necessary, and may also appear in the TABLE
OF CONTENTS, to guide you to specific
component information.
Additionally, a two-character alpha code (i.e.
[NV] RINGS, PISTON) is shown with each
operation. This alpha code, in combination with
the three-digit Group number, identifies the
specific assembly, subassembly or part, and
directly relates to the first five positions of the
operation code listed in the Service Labor Time
Standards Manual, TS477.

ABOUT THIS MANUAL
CHANGES FROM THE
EXISTING E7 MANUAL
Mack Trucks, Inc. has made many major
improvements to this E7 Service Manual, with
changes to both content and organization. The
specifications have been revised to reflect
changes and improvements in E7 engines.
All specifications and torque values are given in
English and metric measurements. Torque
values are also included in the text, eliminating
the need to refer to the Fits and Limits chart each
time a specified torque value is required. The
Special Tools list has been revised to include new
special tools. Warnings, cautions, notes and
service hints help the technician service the
engine safely and efficiently.
The ENGINE DISASSEMBLY section shows how
to remove components in an order that requires
the least amount of handling. It includes brief
component descriptions and information needed
to properly service that component.
The BENCH PROCEDURES section guides the
technician in disassembly, cleaning, inspection
and assembly of each component. It also helps in
determining if the part is serviceable or should be
replaced. This section alerts the user to
component upgrades and helps the technician to
decide whether to use the latest available parts or
reinstall existing parts. Precise descriptions aid in
component identification.
The ENGINE ASSEMBLY section includes stepby-step procedures for reassembling the engine.
This helps to ensure proper installation and
longer service life.
The SETUP AND ADJUSTMENTS section has
the latest setup information, complete with charts
showing necessary data for adjusting all E7
engine models. Engines perform best and
conserve fuel most efficiently when adjusted
properly.
Two additional sections are included as guides
for removing and reinstalling the engine. Both
sections are generic in nature. E7 engine
installation procedures vary from one vehicle
style to another. These 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 E7 engine. The
TROUBLESHOOTING section contains
questions to help the technician consider all
possible problem sources.
This service manual has been revised to include
all applicable active service bulletins and service
letters since publication of the earlier E7 Service
Manual (October 1992).

INTRODUCTION
This manual is intended to assist the technician
in properly overhauling MACK E7 engines. The
manual is divided into nine major sections.
Working on the E7 engine is not difficult, but like
most present-day precision equipment, it requires
proper tools and knowledge.
The overhaul procedures are separated into three
sections: engine disassembly, bench procedures
and engine assembly. Each section contains
detailed procedures that must be followed in the
order specified. If a step calls for a procedure that
has already been described earlier in the manual,
you will be referred to the section where the
original procedure appeared. This manual covers
the overhaul of an engine once it is removed from
the vehicle, but also gives instructions for
removing the engine from a nonspecified chassis.
The new E7 is the most fuel-efficient diesel
engine MACK has ever produced. This engine
provides higher horsepower ratings, better fuel
economy, increased durability and improved
serviceability. In addition, the E7 still easily meets
all applicable emissions standards. All this,
coupled with the latest manufacturing techniques
and equipment, makes the new E7 the highestquality MACK engine ever made.
Externally, all E7 engine models look the same.
However, Mack Trucks, Inc. has made many
major internal design changes to comply with
current and future EPA emission standards. To
properly identify the E7 engine model year, refer
to the engine information plate and the following
pages of this section for additional engine plate
information.

200 GENERAL INFORMATION
ENGINE MODEL
IDENTIFICATION
Engine Information Plate
All engines are identified by an engine
information plate located on the front valve cover
of the engine. This plate indicates the engine’s
11GBA number, emission standards, serial
number and various engine adjustments. The
engine is also identified by the serial number
stamped into the cylinder block above the timing
cover on early engines, or on the pad just to the
rear of the air compressor on later engines.
For some current MACK engines, the engine
information plate also includes pertinent
emissions characteristics of NO
unique to that engine.
A given MACK engine may meet federal emission
regulations in 49 states (excluding California) or
an engine may meet emission regulations of all
50 states (including California). To determine
which regulations a given engine meets, refer to
the engine information plate. If the engine plate
has a series of dashes in the long upper-left
block, and two dashes in the CALIF. FAMILY
block, the engine does not meet California
regulations.

Figure 3 — Engine Information Plates
New Engine Information Plate
The following explanations are provided to aid in
interpreting some of the key information found on
the new engine information plate (effective late
1996). Refer to Figure 1-4.
Block 1 — U.S. EPA Regulations
앫 An “X” in block one means the engine meets
United States EPA regulations for the year
stamped in block No. four.
앫 Two dashes in block one indicates the
engine does not meet United States EPA
regulations for the year stamped in block
No. four. This is only permissible with certain
export engines. All domestic engines will
have an “X” in block one.
Block 2 — California Regulations
앫 An “X” in block two indicates the engine
meets California emissions regulations for
the year stamped in block No. four. This
engine is referred to as a “50-state” engine
and can be sold in any state throughout the
U.S.
앫 Two dashes stamped in block two means
the engine does not meet California
emissions regulations. If an engine has an
“X” in block one and two dashes in block
two, it is referred to as a “49-state” engine,
meaning it is not certified for sale in
California.

200 GENERAL INFORMATION
Block 3 — ADR Regulations
앫 An “X” in block three means the engine has
been certified to meet Australian emissions
regulations.
앫 Two dashes in block three means the engine
does not meet Australian emissions
regulations.
Block 4 — Model Year
앫 The four-digit numeral stamped in block four
represents the year in which the engine was
certified.
Block 5 — Federal Family
앫 A two-digit numeral stamped in block five
denotes the Federal Family to which the
engine belongs, for emissions certification
purposes.
앫 All domestic engines will have a two-digit
Federal Family number in block five.
Block 6 — California Family
앫 If the engine meets California emissions
regulations, the same two-digit numeral
stamped in the Federal Family block is
stamped in the California block.
앫 If the engine does not meet California
emissions regulations, there will be two
dashes in block six.
Block 7 — Initial Injection Timing
앫 Block seven indicates the initial setting for
E7 injection timing.
앫 E7 EUP (E-Tech™) engines do not have an
initial injection timing, as this is controlled
electronically. E-Tech™ engines have “NA”
stamped in block seven.
Block 8 — Engine Brake
앫 This block is only used when the engine is
equipped with a Jake Brake. The stamping
in this block indicates the Jake Brake slavepiston lash setting.
