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.

(PWM) Pulse width modulation (%) (R) Rack position (mm) Rack sensor output characteristics 1. Rack limit adjustment (1)Measure the rack position R2 for PWM a2%. (2)Confirm that it is within the range R2 = 15+-1 mm. (3)Measure the rack position R1 at PWM a %. (4)Confirm that it is within the range R2 - R1 = 10+-0.1 mm. 2. Check the limp home operation. (1)Move the switch box's limp home switch to the limp home side. (2)Confirm rack position L1 (mm ) and L2 (mm) for PWM in the above table. 3. Check the pull down operation. (1)Confirm that the rack position is 19 mm at PWM B%. (2)In the conditions described in the above table, move the switch box's pull down switch to the pull down side and confirm that the rack position momentarily becomes 1 mm or less.
