Introduction:

• This workshop manual contains technical data, descriptions and repair instructions for the Volvo Penta products or product versions noted in the table of contents.
• Check that you have the correct Workshop Manual for your engine. Read the available safety information, ”General information” and ”Repair instructions” in this workshop manual before you start to do any service work.

General information:
About this Workshop Manual:

This workshop manual contains descriptions and repair instructions for the standard versions of the TAD950VE, TAD951VE, TAD952VE, TAD1250VE, TAD1251VE, TAD1252VE and TWD1643GE engines. The workshop manual can illustrate tasks done on any of the engines noted above.

• This means that the illustrations and photographs which clarify certain details might not correspond with other engines in some cases. Repair methods are similar in all important respects, however. If this is not the case, this is noted. Important differences are noted separately.
• The engine designation and number are noted on the number plate and engine decal. The engine designation and number must always be given in all correspondence about any product. The workshop manual is produced primarily for the use of Volvo Penta workshops and service technicians.
• For this reason the manual presupposes a certain basic knowledge and that the user can carry out the mechanical/electrical work described to a general standard of engineering competence. Volvo Penta constantly improves its products, so we reserve the right to make modifications without prior notification. All information in this manual is based on product data which was available up to the date on which the manual was printed. Any material changes introduced into the product or service methods after this date are notified by means of Service Bulletins.
