Preface
Preface Structure The "Technical Litenure" for the "911 Carrera (993)" model is basically structured as before, i.e. the structure follows the familiar repair groups. A new feature is that the structure includes the main groups 0 to 9 and the main group D.
Main groups:

As a new feature, however, the former item 6 (Repair group diagnosis) is no longer filed in the volume corresponding to the respective repair group. The Diagnosis test plans I diagnosis procedures have been combined in a separate Diagnosis volume broken down according to the main groups 0 to 9. Another new feature is that the contents of the "Service Information Technik" are indicated in the Repair Manual. This brochure concentrates on a description of the design and function of components and of the new features introduced for a particular model year.
Preface
911 Carrera (993)
Service Number All major repair procedures and repair descriptions are identified by a two- or four-digit Service Number completed by two additional digits to identify the work that corresponds to the first six digits of the working position number in the Working Times and Damage Catalog.
Example:
Presentation 30 37 37 50

Dismantling and assembling clutch control shaft
in the various documents Working position no. from Working Times and Damage Catalog, consisting of repair group, component designation,
activity and index
30 37 37
Six-digit number in Repair Manual, consisting of repair group, component designation and activity
3037
Service number in Service Information, consisting of repair group and component designation
Goal The introduction of a service number in the "technical literature" is intended to facilitate standardization and positive identification to allow direct cross-referencing among the various documents. This is of particular importance with regard to the use of electronic media.
Structure
of the Repair Manual
This Repair Manual describes all the important operations that require special instructions to ensure proper completion. This manual is an essential source of information for the shop foreman and the shop mechanics as the information in this manual must be observed at all times to keep the vehicle in safe and roadworthy condition. The basic safety rules of course also apply without exception to all repairs on motor vehicles.

The Repair Manual will be updated regularly with supplements which must be filed immediately to maintain the usefulness of the manual. Appropriate entries must be made in the registration sheet to prove that the manual is complete. The contents of the Repair Manual will be supplemented by Technical Information Bulletins which will be integrated into the manual from time to time. Desciptions of design and function can be found in the service training course reference material.
