Service Procedures and Tool Usage
Anyone using a service procedure or tool not recommended in this manual must first satisfy himself
thoroughly that neither his safety nor vehicle safety will be jeopardized by the service method he selects.
Individuals deviating in any manner from the instructions provided assume all risks of consequential
personal injury or damage to equipment involved.
Also note that particular service procedures may require the use of a special tool(s) designed for a
specific purpose. These special tools must be used in the manner described, whenever specified in the
instructions.
1. Before starting a vehicle, always be seated in the driver’s seat, place the
transmission in neutral, be sure that parking brakes are set, and disengage
the clutch.
2. Before working on a vehicle, place the transmission in neutral, set the
parking brakes, and block the wheels.
3. Before towing the vehicle, place the transmission in neutral and lift the rear
wheels off the ground, or disconnect the driveline to avoid damage to the
transmission during towing.
REMEMBER,
SAFETY . . . IS NO ACCIDENT!

SAFETY INFORMATION
Mack Trucks, Inc. cannot anticipate every
possible occurrence that may involve a potential
hazard. Accidents can be avoided by recognizing
potentially hazardous situations and taking
necessary precautions. Performing service
procedures correctly is critical to technician safety
and safe, reliable vehicle operation.
The following list of general shop safety practices
can help technicians avoid potentially hazardous
situations and reduce the risk of personal injury.
DO NOT perform any services, maintenance
procedures or lubrications until this manual has
been read and understood.
앫Perform all service work on a flat, level
surface. Block wheels to prevent vehicle
from rolling.
앫DO NOT wear loose fitting or torn clothing.
Remove any jewelry before servicing
vehicle.
앫ALWAYS wear safety glasses and protective
shoes. Avoid injury by being aware of sharp
corners and jagged edges.
앫Use hoists or jacks to lift or move heavy
objects.
앫NEVER run engine indoors unless exhaust
fumes are adequately vented to the outside.
앫Be aware of hot surfaces. Allow engine to
cool sufficiently before performing any
service or tests in the vicinity of the engine.
앫Keep work area clean and orderly. Clean up
any spilled oil, grease, fuel, hydraulic fluid,
etc.
앫Only use tools that are in good condition,
and always use accurately calibrated torque
wrenches to tighten all fasteners to their
specified torques. In instances where
procedures require the use of special tools
which are designed for a specific purpose,
use only in the manner described in the
instructions.

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, the
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
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 step-
by-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).
