1. When installing the pre-stroke actuator on the pump, first tighten the installation bolts loosely, then move the actuator fully counterclockwise (viewed from the drive side).
Temporary tightening torque: 1 - 1.5 N.m (0.1 - 0.15 kgf.m)
2. Move the actuator in the clockwise direction when viewed from the drive side, and adjust so that it becomes the adjustment point of the adjustment value. Then tighten it.
Tightening torque: 7^9 N.m (0.7^0.9 kgf.m)
3. After prestroke actuator installation adjustment, simultaneously stamp both the actuator side and housing side.

Engine model and total displacement(2) The engine serial number is shown by a label attached to the top of the rocker cover. It is also stamped on the injection pump mounting surface of the cylinder block.(3) The engine serial number is stamped as shown below:
Location of engine serial number label1.3 Engine Model and Application Codes(1) The engine model code is designated as shown below.* Engine model and classification * Model code 2. Specifications
2.1 Major Specifications 3. Points to Note for Disassembly and Reassembly
This service manual contains recommended service procedures for your Mitsubishi diesel engine. It also contains information on special tools and basic safety precautions. Since hazards exist in many places, the safety precautions in this manual should not be considered exhaustive. It is your responsibility to exercise common sense and to pay attention to safety at all times.Always perform service operations in accordance with this manual. When performing disassembly and reassembly operations, also observe the general instructions given below.3.1 Disassembly(1) Use only the correct tools and instruments.(2) Use an overhaul stand or work bench if necessary, and make ready a surface where removed parts can be arranged. Remove parts in the specified disassembly sequence.(3) Arrange disassembled parts neatly to avoid losing them.(4) Pay attention to alignment and position marks. If necessary, make your own marks to facilitate reassembly.(5) Carefully check parts for abnormalities when removing or cleaning them. Abnormalities may be harder to see after parts have been removed or cleaned.(6) Strive to ensure safety at all times. It is particularly important to make sure that items being disassembled are properly balanced and to pay attention to safety when moving heavy items. Use jacks and chain blocks when necessary.3.2 Reassembly(1) Wash all engine parts (except oil seals, O-rings, and rubber seals) in cleaning solvent and dry them with compressed air.(2) Use only the correct tools and instruments.(3) Use only high-quality oils and greases of the specified types. Be sure to apply a coat of oil, grease, or sealant wherever specified.(4) Use a torque wrench to achieve all specified tightening torques.(5) As a general rule, all gaskets and seals must be replaced with new ones. Apply adhesive where required, and be careful not to apply too much.
