REMOVAL AND INSTALLATION


warning Certain components of this vehicle, such as TPMS transmitter may contain perchlorate materials. Before deployment and/or disposal of these components, review and comply with all applicable local regulations.
caution
  • Do not vary the angle of valve except at mounting on the rim.
  • Ensure cap is always in place except when adjusting tyre pressure.
  • If the valve core and cap are replaced, use a genuine replacement part. The valve core is similar to a conventional one, but uses nickel plating to avoid corrosion.
  • Replace the seal washer with a new one every five years or when the tyre is replaced.
  • Do not drop the TPMS transmitter from height greater than 1 meter.
  • Do not expose the TPMS transmitter to extraneous magnetic fields.
  • TPMS transmitter should not be stored at temperatures above 80°C.
  • TPMS transmitter should not be exposed to temperatures above 100°C.
  • If the TPMS transmitter is replaced, execute "Tyre Pressure Sensor ID Registration" on M.U.T.-III "Special Function."
  • Be careful not to damage the TPMS transmitter.
Pre-removal Operation
  • Wheel and Tyre Removal

 Post-installation Operation
  • Wheel and Tyre Installation
  • Tyre Pressure Sensor ID Registration If a new TPMS transmitter is installed (Refer to ).
  • After the tyre pressure sensor ID registration, check that the TPMS warning lamp does not illuminate or flash.

REMOVAL SERVICE POINTS

<<A>> CAP/VALVE CORE/NUT REMOVAL
<When a flat tyre repair agent has never been used>
1.
caution Ensure cap is always in place except when adjusting tyre pressure.
Remove the cap.
2.Rotate tyre so that valve stem is in the 6 o’clock position.
3.Use a long-reach 17.2 mm socket to unscrew the valve nut a few turns. Slowly push valve stem into tyre so that tyre pressure is relieved.
4.Once tyre pressure is released, remove nut and let TPMS transmitter fall into tyre.

<<B>> TPMS TRANSMITTER REMOVAL
caution Be careful not to damage the TPMS transmitter.






1.<When a flat tyre repair agent has been used before>
(1) Fix the tyre on a tyre changing machine. Then apply a bead breaking shoe to the shown range to disengage the tyre bead from the wheel rim.
note For the opposite side, repeat the same procedure.
(2) Fix the tyre on a tyre changing machine so that the TPMS transmitter is positioned as shown.
(3)
caution Do not allow any impact or shock to the TPMS transmitter with a tyre lever or tyre bead.
Use a tyre lever to disengage the upper bead.
(4) Rotate the tyre in the direction of arrow to disengage the tyre bead from the wheel.
(5) Fix the tyre on a tyre changing machine so that the TPMS transmitter is positioned as shown.
(6)
caution Do not allow any impact or shock to the TPMS transmitter with a tyre lever or tyre bead.
Use a tyre lever to disengage the lower bead.
(7) Rotate the tyre in the direction of arrow to disengage the tyre bead from the wheel.

2.<When a flat tyre repair agent has never been used>
(1) Place on tyre changing machine and break both tyre beads ensuring that the TPMS transmitter remains in the bottom of the tyre.
(2) Lubricate tyre well and remove outer side of the tyre.
(3) Reach inside the tyre and remove the TPMS transmitter.
(4) Remove tyre from rim using proper tyre changing equipment procedures.

<<C>> SEAL WASHER/VALVE REMOVAL
caution
    Remove the seal washer to prevent scratching the valve of the TPMS transmitter.

1.Hold the TPMS transmitter and the seal washer, then extract the seal washer. Take care to not damage the valve thread.

2.Clean the TPMS transmitter and the valve stem. <In case of not removing the valve>
note If the valve comes out from transmitter, install it to where it was. (This is not failure)

3.Removal the valve from housing as shown.

INSTALLATION SERVICE POINTS

>>A<< VALVE/SEAL WASHER/TPMS TRANSMITTER/NUT INSTALLATION
caution
    Install the seal washer to prevent scratching the valve of the TPMS transmitter.

1.Install the valve to housing as shown.

2.Insert the seal washer up to the base of the TPMS transmitter, making sure to secure the valve base with a thumb as shown.
Wipe the seal and threading.

3.
caution
  • Visually check that TPMS transmitter is not deformed or damaged.
  • When installing the TPMS transmitter, be sure the rim, seal valve and nut are clean.
  • Ensure the grommet is located inside the valve hole before installing the nut.
  • While installing the nut, push the TPMS transmitter to maintain the lower lip of the transmitter case is in contact with the rim without clearance.
  • While installing the valve nut, ensure the tool is kept aligned to the valve and the valve hole.
Install the valve, in the valve hole, without modifying the angle of the stem (retain position of delivery). The laser marking should be visible at the operator.

4.When the valve is completely inserted, maintain the TPMS transmitter in contact with the rim, then screw manually the nut until the contact with the wheel.

5.While maintaining the TPMS transmitter contact with the rim by applying pressure to the back of the valve, slightly press on the cap to wards the centre of the wheel in order to adapt the angle of the valve/TPMS transmitter to the profile of the rim.
It is mandatory to guarantee the contact of the housing unit on the rim drop centre.

6.While maintaining the TPMS transmitter and valve in position, screw the nut with a torque wrench.
Take care that the wrench socket is correctly inserted on the nut.
Specified torque: 8.0 ± 0.5 N·m

>>B<< TYRE BEAD MOUNTING

1.Prepare the tyre and fix the rim as usual.

2.Put the tyre on the rim, so that the cross point of the belt with the rim is approximately 20 cm away from the valve.

3.Engage the shoe and make sure that 20 cm is maintained between the cross point and the valve.
The arrow shows the direction of rotation of the wheel.

4.Turn the wheel in order to engage all the first side of the tyre.
note The standard shoes can pass over the sensor without damaging it.

5.Put the second side of the tyre in position, so that the cross point of the belt with the rim is approximately 20 cm away from the valve. The curved arrow shows the direction of rotation of the wheel.

6.Turn the wheel in order to engage all of the second side of the tyre.
note The standard shoes can pass over the sensor without damaging it.

>>C<< TYRE PRESSURE INFLATION/NUT RETIGHTENING
caution After tyre inflation, retighten the valve nut to 8.0 ± 0.5 N·m. This is necessary, because the TPMS transmitter is secured to the wheel with the valve nut and rubber grommet. The rubber grommet will be depressed by tyre pressure or deteriorate over a period of time, which requires the valve nut to be retightened.
Inflate tyre to required pressure, then retorque the valve nut to 8.0 ± 0.5 N·m.
