5. Install ball-nut and valve housing assembly.
-
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.)
6. Install sector shaft.
-
Tape the sector shaft serrations to protect the seal ring from damage.
-
Align the center tooth of ball nut with that of the sector shaft.
7. Install O-ring.
8. Install top cover assembly and tighten the fixing bolts to specified torque.
Torque: 47 Nm (35 ft. lbs.)
9. Adjust the backlash between the worm gear and the ball nut.
-
With the worm gear rotating, set it to the straight ahead position.
-
Set the worm shaft preload to below 10 kg/cm with the sector shaft adjusting screw.
-
Measure the worm shaft preload with the worm gear turned 450° both to the right and to the left. The worm gear preload in these positions
should be 0.4 - 0.6 Nm (4 - 6 kg/cm) lower than in the straight ahead position.
-
Lock the sector shaft adjusting screw with the lock nut.
Lock nut torque: 41 Nm (30 ft. lbs.)
