INSTALLATION

1. HANDLING PRECAUTIONS FOR STEERING ACTUATOR ASSEMBLY

NOTICE:

  • Be careful that the No. 2 seal lip or boot does not turn outward while carrying or installing the steering actuator assembly. If installing a new steering actuator assembly, make sure that the spiral center lock pin is securely inserted.
  • Do not use the steering actuator assembly if it has been dropped.

2. INSTALL STEERING ACTUATOR ASSEMBLY

(a) Make sure that the power steering link assembly is centered.

(b) Install the steering actuator assembly.

(1) If installing a new steering actuator assembly:

Install the steering actuator assembly with the white line on the upper surface of the spiral case facing down.

NOTICE:

Do not pull out the center lock pin.

(2) If reinstalling the removed steering actuator assembly:

  • Slowly turn the spiral case clockwise until it locks.
  • Turn the spiral case two turns counterclockwise from the lock position.
  • Align the slit of the sliding yoke with the alignment mark (▲).
  • Install the steering actuator assembly with the white line on the upper surface of the spiral case facing down.

(c) Align the matchmarks on the No. 2 steering intermediate shaft and steering actuator.

(d) Install the bolt.

Torque: 35 N·m (360 kgf·cm, 26 ft·lbf)


(e) Using needle nose pliers, lock the clamp to the steering column hole cover to install it.

NOTICE:

Be careful when performing the operation as the clamp may not lock if the claws of the clamp are deformed.

(f) Move the lock in the direction of the arrow and connect the steering actuator connector.
