HOW TO USE THIS MANUAL
This Service Manual describes the specifications of Mitsubishi diesel engines (land and standard applications)
and relevant service standards, as well as the procedures for servicing the engines such as for disassembly,
inspection, repair and reassembly. This manual is divided into Groups. Each Group covers a specific area of

The fuel injection pump, the governor and the turbocharger are handled in a separate manual.
Major contents of Groups are listed on the “General Contents” page. Detailed contents of each Group are
listed on the first page of that Group.
