WORKSHOP MANUAL 944
This Workshop Manual descr
ibes all of the important operations for which special instructions are required to
assure proper completion. This manual is essential for shop foremen and mechanics, who need this
information to keep the vehicles in safe operating condition. The basic safety rules, of course, also apply to
repairs on vehicles without exception.
Only those repair jobs deviating from those of vehicle type 924 are described in the 944 Workshop Manual.
Refer to the 924 Workshop Manual for all other information.
The information is grouped according to repair numbers which are identical to the first two digits of the
warranty job codes.
The repair group index, list of contents and the register tabte are quick guides to find information in the
manual. The layout drawings in this manual are numbered in the order of disassembling and, if necessary,
also have information on assembly or installation and application of special tools.
Descriptions of design and function can be found in the service training course reference material.
This Workshop Manual will be kept up to date with Technical Information Bulletins, which will be made part
of the manual from time to time. We recommend that these bulletins be filed in the standard type folder
provided for this purpose.
