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.

A:Sealing position B:Pre-stroke actuator 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.

Rack limit adjustment (1)After mounting the joint (B), select the shim (D) so that the rack position is in the rack limit position. (2)Install the rod (e) to the block (c). (3)At the rack limit, set the distance between the pump end face and the rod (E) to L1. 2. Rack sensor (1)Screw in the bobbin (A) until it contacts the joint (B). (2)Fix the speed control lever at the full side and set the pump speed at N1. (3)Adjust the depth that the bobbin (A) is screwed in so that the control unit's rack sensor output voltage is VR+-0.01 (V), then tighten the nut (F). (If equipped with a boost compensator, perform with boost pressure applied.) (4)Adjust the bobbin (a) so that the rack sensor output voltage becomes VR +-0.01(V). (5)Apply red paint to both the joint (b) and the nut (f) join, and the joint (b) and the pump join. Output voltage VR +-0.01(V), speed N1 r/min, rack position Ra mm
