Introduction

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

ly. It should be consulted regularly by workshop personnel as an addition to the practical and theoretical

knowledge obtained in Training School courses. It is a contribution towards achieving even higher Service

quality.

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.

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

assembly, Repair, Assembly, Installation.

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

11 . 10

Chap.

Page number within chapter

G 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.

G 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 you to consult the

detailed illustrations on the Parts microfiches as an additional source of information.
