STEERING COLUMN ASSEMBLY REASSEMBLY

Note


  • When using a vise, do not overtighten it.

  • Do not drop the power steering motor assembly, strike it with tools or subject it to impacts.

  • If the power steering motor assembly is subjected to an impact, replace it with a new one.

  • Do not pull the wire harness of the power steering motor assembly.

  • Do not allow any moisture to come into contact with the power steering motor assembly.

  • Do not loosen any bolts not mentioned in the procedure.


  1. INSTALL POWER STEERING MOTOR ASSEMBLY


    1. A01J9IO

      Install a new electric power steering motor shaft damper to the electric power steering column sub-assembly.

    2. A01JBJM

      Install a new electric power steering motor shaft spacer to the electric power steering column sub-assembly.

    3. A01JD9A

      Temporarily install the power steering motor assembly to the electric power steering column sub-assembly with the 2 bolts.

      Note

      When temporarily installing the 2 bolts to the power steering motor assembly, do not tighten them all the way down.

    4. A01J9HD

      Secure the steering column assembly in a vice using aluminum plates and a piece of cloth.

      Note


      • Do not overtighten the vice, as the steering column assembly may become deformed.

      • Secure the power steering motor assembly so that it is directly upright.

      • Support the steering column assembly with a wooden block or similar item to ensure that it does not fall.

    5. A01JAXAE01

      Using SST, turn the steering main shaft once 180 degrees to the left and then 180 degrees to the right at a speed of 60 rpm, and repeat 2 to 3 times to adjust the axis centering of the power steering motor assembly.

      SST
      09616-00011

    6. Remove the steering column assembly from the vice.

    7. A01JD0S

      Tighten the 2 bolts.

      Torque:
      19 N*m  { 189 kgf*cm, 14 ft.*lbf }
    8. A01J9HD

      Secure the steering column assembly in a vice using aluminum plates and a piece of cloth.

      Note


      • Do not overtighten the vice, as the steering column assembly may become deformed.

      • Support the steering column assembly with a wooden block or similar item to ensure that it does not fall.

    9. A01JAXPE01

      Measure the turning torque of the steering main shaft using SST.

      SST
      09616-00011
      Torque:
      Turning torque
      0.9 to 1.5 N*m  { 10 to 15 kgf*cm, 8 to 12 in.*lbf }

      Note

      Ensure that there is no abnormal resistance during rotation.

      If the torque is not as specified, readjust the axis centering of the power steering motor assembly.

    10. A01JAKV

      Engage the claw to install the torque sensor harness connector.

        *5 19 mm (0.75 in.)
        *6 59°
        *7 65°

        Install 2 new clamps and each tape to the wire harness as shown in the illustration.

        Note


        • Secure the wire harness to the power steering motor assembly within the range indicated by *6

        • Wrap the tape more than 2 times.

        • As heat from the power steering motor assembly may generate smoke, use heat resistant tape (resistant to 100°C (212°F) or more).
