TURBO REPAIR MANUAL

This repair manual describes all of the important operations for which special instructions are

required to assure proper completions. This manual is essential for the shop foremen and

mechanics, who need this information to keep the vehicles in a safe operating condition. The

basic safety rules, of course, also apply to repairs on vehicles without exception.

The 930 Turbo Repair Manual only describes repair operations which differ from those for 911

models. Refer to the 911 Repair Manual for all other information.

The information is grouped according to repair numbers, which are identical to the first two digits

of the repair time and warranty code.

The repair group index and register cards are quick guides to find information in the manual.

Discriptions of design and function can be found in service training course reference material.

This repair manual will be kept up to date with workshop bulletins; the information of these

bulletins will be made part of the manual from time to time. We recommend that the Workshop

Bulletins be filed in the special folder provided for this purpose.
