Operation sequence
1. Turn the prestroke actuator OFF.
2. Turn the camshaft as far as the No.1 cylinder's beginning of injection position.
3. Check that the pointer alignment mark of the injection pump and the alignment mark of the flywheel are matching.
4. If they are not matching, erase the alignment mark on the flywheel side, and stamp an alignment mark on the flywheel position that matches with the pointer side alignment mark.
5. Check again that the coupling's key groove position is in the No.1 cylinder's beginning of injection position.

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.

1. Rack sensor adjustment (-0620)
(1)Fix the speed control lever at the full position
(2)Set the speed to N1 r/min.
(If the boost compensator is provided, apply boost pressure.)
(3)Adjust the bobbin (A) so that the rack sensor's output voltage is VR+-0.01.
(4)At that time, rack position must be Ra.
(5)Apply G at two places.
