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 clockwise (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 counterclockwise 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.

Rack sensor adjustment
1. Threaded type rack sensor (-5*20, P type, no TICS rack limit).
(1)Screw in the bobbin (A) until it contacts the joint (B).
(2)Fix the pump lever.
(3)At speed N1 and rack position Ra, adjust the amount that the bobbin is screwed in so that the amp's output voltage is V1.
(4)Fix using the nut (F).
(5)Affix the caution plate to the upper part of the joint (B).
(6)Apply (G) at two places.
Connecting part between the joint (B) and the nut (F)
Connecting part between the end surface of the pump (H) and the joint (B)
2. Range for screw-in adjustment between the bobbin (A) and the joint (B) is 9 threads.
Screw in to the end from (the position where the bobbin (A) is rotated 9 turns).
