INTRODUCTION
These Repair Instructions are to assist you in performing the necessary maintenance and repair work expertly and correctly.
This complements the practical and theoretical training given in our service training schools.
Beginning with 198:; models. Repair Instructions are divided into:
Repair Instructions for the Series
The Repair Instructions (3, 5, 6, 7 and 8 Series) describe removal, installation and replacement of construction groups on the
vehicle.
Construction Group Repair Instructions for BMW Automobiles
The Construction Group Repair Instructions (Main Groups 11, 12, 13, 23, 24 and 33) describe removal, installation and
replacement of construction groups on removed assembli es. Testing instructions and troubleshooting charts also feature in the
Construction Group Repair Instructions.
For all Technical Data (tightening torques, adjustment values etc.) technical data microfilms are provided.
The Repair Instructions (microfilm or manual) illustrate work which is only possible to perform on standard production cars, i.e. not
applicable to cars which have been subsequently modified.
The structure of these Repair Instructions is based on the same numbering system as the flat rate manuals (FR numbers),
Cross references to other FR (Fl at Rate) numbers are only intended as assistance and must not be used for extension of the flat
rates.
The individual page numbering, for example 64 - 11/8 means:
64 Main Group
11 Sub-group
8 Serial numbers
All the special tools ment ioned in the Repair Instructions are summarized in the special tool microfiche, order no. 01 99 9 699 422.
The use of special tool is illustrated in the descriptions of various repair operations.
Normally, the Repair Instructi ons only describe the removal work required for each operati on . Installation takes place in reverse
order. If it does not, installation notes are provided to explain the correct procedure.
In contrast to this, the removal and installation operations for complex tasks are described separately.
The Service Information bulletins provide regul ar information on improvements and modifications. As an additional source of
information, we recommend using the illustrated parts microfiches.
