Repair Manual

Introduction

This repair manual will help you to perform all the main maintenance and repair work correctly and efficient-

ly. If it is consulted regularly by workshop personnel it will form a useful addition to the theoretical and prac-

tical knowledge acquired at the BMW Training Centre. It is a contribution towards achieving even higher

Service quality.

A new issue of this repair manual will be published if amendments or additions (supplements) are needed.

All information in both text and illustrations refers to motorcycles in standard condition or with genuine

BMW accessories installed, and not to motorcycles which have been modified in any way to depart from

the manufacturer’s specification.

•The repair manual is structured in the logical sequence of the work to be performed: Removal, Disas-

sembly, Repair, Assembly, Installation.

•The entire contents are divided into individual chapters, corresponding to the Construction Groups.

11 . 10

Chapter Page number within chapter

An arrow symbol followed by the chapter and page numbers is a reference to another chapter,

e.g. Ób ............................................See Group 46

•Work to be performed during an Inspection is described in Group “00”. The various inspection routines

are numbered I, II, III and IV. This numbering is repeated in the work descriptions which follow, so that

work can take place without interruption.

•Use of the BMW special tools needed for certain tasks is described in the work instructions.

If the need arises, repair instructions are also issued in the form of Service Information. This information is

of course incorporated into the next issue of the repair manual. We also recommend, as an additional

source of information, the Electronic Parts Catalogue (ETC), which contains clear and easy-to-follow illus-

trations.

If the work described here is restricted to a particular equipment specification, for instance if a specific op-

tional extra (OE) is fitted, this is stated in square brackets at the start of the item concerned, e.g. [With heat-

ed handlebar grips].

Please refer to the following pages as well for a description of other symbols used and how to work with it.
