    3. Install the vane pump rotor with the round ends facing outward.

  6. INSTALL VANE PUMP SHAFT SNAP RING


    1. A01LAQU

      Using a snap ring expander, install a new snap ring onto the pulley shaft.

  7. INSTALL REAR HOUSING


    1. Coat the vane pump rear housing of the shaft sub-assembly with pulley and the surrounding surface with power steering fluid.

    2. Coat a new O-ring with power steering fluid and install it to the rear housing.

    3. Align the straight pin of the rear housing with the dent of the cam ring, side plate and front housing.

      Note

      Make sure that the O-ring is not out of position before installing the rear housing.

    4. Install the rear housing with the 4 bolts.

      Torque:
      22 N*m  { 224 kgf*cm, 16 ft.*lbf }

  8. INSTALL POWER STEERING OIL PRESSURE SWITCH (for 2WD)

    2. Install the power steering oil pressure switch onto the vane pump assembly.

      Torque:
      21 N*m  { 214 kgf*cm, 15 ft.*lbf }

  9. INSPECT ROTATING TORQUE


    1. A01LCVFC01
      *a Service Bolt

      Check that the vane pump assembly rotates smoothly without abnormal noise.

    2. Provisionally install the service bolt.

      Recommended Service Bolt
      Item Specified Condition
      Thread Diameter 10 mm (0.394 in.)
      Thread Pitch 1.25 mm (0.0492 in.)
      Bolt Length 50 mm (1.97 in.)

    3. Using a torque wrench, check the pump rotating torque.

      Standard rotating torque
      0.27 N*m (3 kgf*cm, 2 in.*lbf) or less

      If the rotating torque is not as specified, check the installation of the housing oil seal.
