In this service manual, the Mitsubishi Diesel Engine (standard model for land use) specifications, maintenance standards and adjustment procedure as well as service procedures such as disassembly, inspection, repair and reassembly are arranged in groups for quick reference. There are separate manuals for the fuel injection pump, governor and turbocharger.A short summary of each group is given in the General Contents, and there is also a table of contents at the beginning of each group.Regarding engine operation and periodical maintenance, refer to the Operation & Maintenance Manual. For component parts and ordering of service parts, refer to the Parts Catalog. Structure and function of the engine are described in various training manuals.Methods of Indication
(1) Parts shown in illustrations and described in text are numbered to correspond with the sequence of disassembly.(2) Inspections to be conducted during disassembly are indicated in a box
in disassembled views.(3) Maintenance standards for inspection and repair are described in text where they are relevant, are also listed in Group 1 in the General Contents.(4) The sequence in which parts are to be assembled is summarized below each assembled view. Such as:
(5) The following marks are used in this manual to emphasize important safety cautions.
Indicates a highly hazardous situation which, if not avoided, can result in death or serious injury.
Indicates a potentially hazardous situation which, if not avoided, can result in death or serious injury.
Indicates a potentially hazardous situation which, if not avoided, can result in minor or moderate injury.
Indicates a potentially hazardous situation which, if not avoided, can result in property damage. Note: Indicates important information or information which is useful for engine operation or maintenance.(6) Tightening torque under wet conditions is indicated as, "[Wet]". When so indicated, apply engine oil to the threaded portion of the fastener. Unless indicated as such, the tightening torque is to be assumed in the dry condition.Terms Used in This Manual
Nominal value - Indicates the standard dimension of a part to be measured.Standard - Indicates the dimension of a part, the clearance between parts, or the standard performance. Since the value is indicated in a range needed for inspection, it is different from the design value.Limit - A part must be repaired or replaced with a new part when it reaches the limit value.Abbreviations, Standard, Etc.
