General information :About the Service Manual:

This Service Manual contains descriptions and repair instructions for the standard versions of the TAD1240GE, TAD1241GE/VE, TA1242GE/VE and TWD1240VE engines. The Service Manual may show work operations performed on any of the engines listed above. Consequently, the illustrations and photographs showing certain details may not be completely accurate in a number of cases.

• The repair methods, however, are essentially the same. The engine designation and number are given on the type plate (see “Technical data TAD1240GE, TAD1241GE/VE, TAD1242GE/VE and TWD1240VE”). The engine designation and number should always be quoted in all correspondence concerning any of the engines. The Service Manual is primarily produced for Volvo Penta’s service workshops and their qualified personnel.
• It is therefore assumed that persons using the manual have the necessary basic knowledge and can perform work of a mechanical/electrical nature that occurs in their profession. Volvo Penta is continuously developing its products and we therefore reserve the right to introduce changes and modifications.
• All the information in this manual is based on product data available up to the time of printing. Any vitally important changes to the product or service methods that are introduced after that date are announced in the form of Service Bulletins.
