200 GENERAL INFORMATION
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 highest-
quality 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.
