PORSCHE WORKSHOP MA NU A L 9 1 4 9 14 / 6
This publication contains the essential removal, installation and adjustment procedures for the Porsche 914-914/6 vehicles sold in the USA and Canada.
Components and procedures described in this manual are identical for both types unless differences are pointed out in the text.
It is assumed that the reader is familiar with basic automotive repair procedures. Special tools required in performing certain service operations are identified in the manual and recommended for usw . of tools Or procedures other than those recommended in this repair manual may be detrimental to the vehicle safe operation as well as the safety of the person servicing the vehicle. Use
The Porsche 914 914/6 Workshop Manual is divided into 8 volumes The volumes are subdivided into 10 Main Groups a follows:
| lst Volume | Engine and Clutch 914 | Main Group No 1 |
|---|---|---|
| 2nd Volume | Fuel System 914 | Main Group No _ 2 |
| 3rd Volume | Engine and Clutch 914/6 Fuel System 914/6 | Main Group No . 1 Main Group No 2 |
| 4th Volume | Transmission | Main Group No. 3 |
| Sth Volume | Front Axle Rear Axle | Main Group No . Main Group No. 5 |

| 7th Volume | Body | Main Group No. 8 |
| 8th Volume | Electrical System | Main Group No. 9 |
Table Caption: This table categorizes automotive components into volumes and assigns them to main group numbers. It appears to be an index or table of contents for a service manual, likely for a Porsche 914 or 914/6.
The binders have transparent plastic pocket on the spine into which the appropriate volume title can be inserted.
To find the individual repair operations , each main group is subdivided into "Chapters" and Sections Every main group is provided with a very detailed table of contents . Refer to example on next page.
The repair operations described in this Workshop Manual are based on the Type 914 vehicle. Repair operations which apply to Type 914/6 vehicles are described separately. The type vehicle to which the reoperation is given on the left or right of the page . applies top Pair
When certain repair operations are similar for both type vehicles, the procedures are described together and the minor differences for the 914/6 emphasized by notes and remarks _
