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.
