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.
Perform all service work on a flat, level surface. Block wheels to prevent vehicle from rolling.
DO NOT wear loose fitting or torn clothing. Remove any jewelry before servicing vehicle.
ALWAYS wear safety glasses and protective shoes. Avoid injury by being aware of sharp corners and jagged edges.
Use hoists or jacks to lift or move heavy objects.
NEVER run engine indoors unless exhaust fumes are adequately vented to the outside.
Be aware of hot surfaces. Allow engine to cool sufficiently before performing any service or tests in the vicinity of the engine.
Keep work area clean and orderly. Clean up any spilled oil, grease, fuel, hydraulic fluid, etc.
Only use tools that are in good condition, and always use accurately calibrated torque wrenches to tighten all fasteners to their specified torques.

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).

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 NOx and particulates 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
An “X” in block one means the engine meets United States EPA regulations for the year stamped in block No. four.
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
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.
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
An “X” in block three means the engine has been certified to meet Australian emissions regulations.
Two dashes in block three means the engine does not meet Australian emissions regulations.
Block 6 — California Family
If the engine meets California emissions regulations, the same two-digit numeral stamped in the Federal Family block is stamped in the California block.
If the engine does not meet California emissions regulations, there will be two dashes in block six.
Block 4 — Model Year
The four-digit numeral stamped in block four represents the year in which the engine was certified.
Block 5 — Federal Family
A two-digit numeral stamped in block five denotes the Federal Family to which the engine belongs, for emissions certification purposes.
All domestic engines will have a two-digit Federal Family number in block five.
Block 7 — Initial Injection Timing
Block seven indicates the initial setting for E7 injection timing.
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
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.
