This service manual specifies the recommended procedures
to be followed when servicing Mitsubishi engines. The
manual also specifies the special tools that are required for
the work, and the basic safety precautions to follow when

Note that this manual does not exhaustively cover potential
hazards that could occur during maintenance, inspection and
service work of engine.
When working on an engine, follow the relevant directions
given in this manual and observe the following instructions:

5.1 Disassembling

(1) Use correct tools and instruments. Serious injury or
damage to the engine will result from using the wrong
tools and instruments.
(2) Use an overhaul stand or work bench if necessary, and
follow the disassembling procedures described in this
manual.
(3) Keep the engine parts in order of removal to prevent
losing them.
(4) Pay attention to assembling marks. Put your marks on
the parts, if necessary, to ensure correct reassembling.
(5) Carefully check each part for defects during
disassembling or cleaning. Do not miss symptoms
which can not be detected after disassembling or
cleaning.
(6) When lifting or carrying heavy parts, exercise utmost
caution to ensure safety. Pay attention to balance of
heavy parts when handling. (Get help, and use jacks,
chain blocks and guide bolts as necessary.)

5.2 Reassembling

(1) Wash all engine parts, except such parts as oil seals, O-
rings and rubber sheets, in cleaning oil and dry them
with compressed air.
(2) Use correct tools and instruments.
(3) Use only high-quality lubricating oils and greases of
appropriate types. Be sure to apply oil, grease or
adhesive to the part wherever specified.
(4) Use a torque wrench to tighten parts correctly when
their tightening torques are specified.
Refer to "List of Tightening Torque."
(5) Replace all gaskets and packings with new ones unless
specified otherwise. Apply adhesive if necessary. Use
only the proper amount of adhesive.
