0000001501 FICD

(A) applied negative pressure (B) Screw (c) Nut 1. Set the actuator as described below. (1)Confirm that there is clearance between the actuator lever and the speed lever. (2)Loosen the nut (C). (3)Push in the screw (B). (4)Apply P1 from the actuator (A) part. (5)Pull out the screw (B) slowly. (6)Tighten and fix the nut (C) when pump speed is Na and the rack position is Ra. (7)Torque the nut (C) to T1. (8)Apply P2 several times. (9)Confirm that the actuator functions normally. (10)Confirm that there is a clearance between the actuator lever and the speed lever at that time.
----------
P1=53.3kPa(400mmHg) P2=53.3kPa(400mmHg) Na=400r/min Ra=10.7+-0.1mm T1=1.2~1.6N-m(0.12~0.16kgf-m)

0000001601 RACK SENSOR

Rack sensor adjustment (1)These types of rack sensors do not need adjustment. Confirm the output as described below. (2)Mount the rack sensor main body to the pump main body. (3)Measure the Vist at pump speed N1 and rack position Ra.
----------
N1=1600r/min Ra=R1(13.1)+0.5mm
----------

Timing setting

(1)Pump vertical direction (2)Position of gear's standard threaded hole at No 1 cylinder's beginning of injection (3)Stamping position on the A/T outer rim (4)Pump bracket check hole position. (5)At the No 1 cylinder's beginning of injection, align with the aligning mark seen through the bracket's check hole and mark the A/T's bevel C1. (6)B.T.D.C.: aa
----------
aa=6deg
