Removal and Installation

REMOVAL 

  1. Remove the wheel and tire using power tool. Refer to Removal and Installation .
  2. Remove the valve cap and the valve core to deflate the tire. Refer to Exploded View .
    NOTE: SYMBOL If the tire is to be reused, apply a matching mark on the tire in line with the position of the valve hole in the wheel for the purpose of wheel and tire balance adjustment after installation.
  3. Lubricate the tire outside bead well with a suitable non-silicone lubricant and separate the tire outside bead from the wheel.
    CAUTION:
    • Do not use silicone lubricant. Use of silicone lubricant will deteriorate the tire and wheel.
    • Do not damage the wheel.
  4. Lubricate the tire inside bead well with a suitable non-silicone lubricant and separate the tire inside bead from the wheel.
    CAUTION:
    • Do not use silicone lubricant. Use of silicone lubricant will deteriorate the tire and wheel.
    • Do not damage the wheel.
  5. Carefully lift and set the wheel and tire onto the tire changer turntable so that the tire pressure sensor (1) is at the bottom. Position the wheel and tire so that the tire pressure sensor is 270 degrees from the mounting/dismounting head (2).

    CAUTION:

    Do not damage the wheel.

    NOTE: SYMBOL To avoid damage to the vehicle, the tire must not slip or spin on the wheel when dismounting, or mounting a tire's outer bead. Damage to the wheel or the tire pressure sensor could result.
  6. Remove the tire from the wheel.
  7. Remove the screw (A) and the tire pressure sensor (1) from the valve (2).

    CAUTION:
    • Do not drop or strike the tire pressure sensor. Replace the tire pressure sensor if it has been dropped from higher than one meter.
    • Do not reuse the screw.
  8. Cut the inner end (A) of the valve using a suitable tool (B).

    Tool (A) number : NI-51980
    CAUTION:
    • Do not damage the wheel.
    • Pull the valve straight through the rim hole perpendicularly to the rim hole.

INSTALLATION 

CAUTION:

Do not loosen the screw if the tire pressure sensor and the valve are being replaced as an assembly.

  1. Clean the valve hole in the wheel.
    CAUTION:

    Make sure there are no burrs, foreign substances, or indications of damage to the wheel.

  2. When reusing the tire pressure sensor, install the tire pressure sensor to the valve using the following procedure: Install the tire pressure sensor (1) to the roll pin (A) of the valve (2).

    CAUTION:
    • Do not drop or strike the tire pressure sensor. Replace the tire pressure sensor if it has been dropped from higher than one meter.
    • Do not reuse the valve.

    Install the screw (1) to the tire pressure sensor and tighten to the specified torque. Refer to Exploded View .

    CAUTION:
    • Do not use silicone lubricant. Use of silicone lubricant will deteriorate the tire and wheel.
    • Do not allow lubricant to contact the air pressure detection hole (B).
  4. Position the tire pressure sensor assembly (1) on the wheel (2).

    CAUTION:
    • Do not damage the tire pressure sensor.
    • Do not allow lubricant to contact the air pressure detection hole.
    • The tire pressure sensor must be oriented tangentially to the rim of the wheel.
  5. Install the tire pressure sensor assembly (2) to the wheel (1) using Tool (A).

    Tool (A) number : NI-51980
    CAUTION:
    • Do not damage the wheel.
    • Install the valve all the way to the wheel.
    • Make sure the valve seats properly in the valve hole in the wheel.
  6. Check the tire pressure sensor assembly (1) position. The tire pressure sensor assembly must be installed to the wheel (2) as shown in the illustration.

    CAUTION:
    • Do not damage the wheel.
    • Do not damage the tire pressure sensor.
    • The tire pressure sensor must be oriented tangentially to the rim of the wheel.
    • If the tire pressure sensor unit position is not correct, rotate the tire pressure sensor unit to the correct position using Tool.
  7. Apply a suitable non-silicone lubricant to the tire inside bead.
    CAUTION:
    • Do not use silicone lubricant. Use of silicone lubricant will deteriorate the tire and wheel.
    • Do not allow lubricant to contact the air pressure detection hole.
  8. Install the tire inside bead (1) onto the wheel (2) in the position shown in the illustration.

    CAUTION:
    • Do not damage the wheel or the tire pressure sensor.
    • Do not allow the tire beads to make contact with the tire pressure sensor.
  9. Place the wheel on the turntable of the tire machine. Make sure that the tire pressure sensor (1) is 270 degrees from the mounting/dismounting head (2).

    CAUTION:

    Do not touch the tire pressure sensor with the mounting head.

  10. Apply a suitable non-silicone lubricant to the tire outside bead.
    CAUTION:
    • Do not use silicone lubricant. Use of silicone lubricant will deteriorate the tire and wheel.
    • Do not allow lubricant to make contact with the tire pressure sensor.
  11. Install the tire outside bead onto the wheel as normal.
    NOTE: SYMBOL
    • If the tire is being reused, align the matching mark applied on the tire with the position of the valve hole in the wheel for the purpose of wheel and tire balance adjustment after installation.
    • To avoid damage to the vehicle, the tire must not slip or spin on the wheel when dismounting, or mounting a tire's outer bead. Damage to the wheel or the tire pressure sensor could result.
  12. Install the valve core.
    CAUTION:

    Do not reuse the valve core.

  13. Inflate the tire. Refer to Tire Air Pressure .
