This manual covers the basic Series 71 In-line Diesel Engines built by Detroit Diesel Corporation.

Complete instructions on operation, adjustment (tune-up), preventive maintenance and lubrication, repair (including complete overhaul) are covered.

This manual was written primarily for persons servicing and overhauling the engine and, in addition, contains all of the instructions essential to the operators and users.

Basic maintenance and overhaul procedures are common to all Series 71 In-line engines and therefore apply to all Inline models (as follows):

71E
71N

Bulletin number: 6SE177. Publication date: December 1972

Multiple engine units are available in various combinations such as side-by-side twins, tandem twins and quads.

The manual is divided into numbered sections.

The first section covers the engine (less major assemblies).

The following sections cover a complete system such as the fuel system, lubrication system or air system.

Each section is divided into sub-sections which contain complete maintenance and operating instructions for a specific subassembly on the engine.

For example, Section 1, which covers the basic engine, contains sub-section 1.1 pertaining to the cylinder block, sub-section 1.2 covering the cylinder head, etc.

The subjects and sections are listed in the Table of Contents on the preceding page.

Pages are numbered consecutively, starting with a new Page 1 at the beginning of each sub-section.

The illustrations are also numbered consecutively, beginning with a new Figure 1 at the start of each sub-section.
