Always keep the ball screw and valve housing assembly in a horizontal position (avoid holding it vertically), or the rack piston will fall off
onto the end of the worm, causing the rack piston to slip out of the worm shaft and ball to fall out.
-
Be careful not to drop the O-ring into the valve housing.
-
Tighten the valve housing bolts to the specified torque.
Torque: 47 Nm (35 ft. lbs.)
