General Information About this Workshop Manual This Workshop Manual contains technical specifica- tions, descriptions and instructions for the repair of the following engines in standard format: MD2010 , MD2020 , MD2030 , MD2040 . This Workshop Manual can show operations carried out on any of the engines li sted above. As a result the illustrations and pictures in the manual that show certain parts on the engines, do not in some cases apply to all the engines listed. How- ever the repair and service operations described are in all essential details the same.
Where they are not the same this is stated in the manual and where the differ- ence is considerable the operations are described sep- arately. The Engine Designations and Engine Number can be found on the product plate. Please always in- clude both the engine designation and the engine number in all correspondance . The service intervals and maintenance proced- ures recommended by Volvo Penta must be fol- l owed. Only Volvo Penta Genuine Spare Parts intended for the certified engine version must be used. Service of injection pumps, pump settings, and i njectors, shall always be conducted by an aut- horised Volvo Penta workshop.
The engine must not be rebuilt or modified in any way, with the exception of the accessories and service kits that Volvo Penta has developed for the engine. 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 of marine propulsion systems and that the user can carry out the mechanical/electrical work de- scribed to a general standard of engineering compet- ence. I nstallation adjustments on exhaust pipes and supply air channels for the engine compartment (ventilation channels) must not, without due care, be conducted since this can influence exhaust emissions.
Seals must not be broken by unauthorised per- sonnel. Q I MPORTANT! Use only Volvo Penta Genuine Spare Parts.
