Disposal

DISPOSAL

CAUTION / NOTICE / HINT

HINT:

The tire pressure warning valve and transmitter is powered by a lithium battery. When disposing of the tire pressure warning valve and transmitter, remove the battery and dispose of it properly.

PROCEDURE

1. DISPOSE OF TIRE PRESSURE WARNING VALVE AND TRANSMITTER

Urethane

(a) Remove the urethane that protects the lithium battery and the circuit board.

(b) Cut the 2 terminals to remove the lithium battery from the tire pressure warning valve and transmitter.

Installation

INSTALLATION

CAUTION / NOTICE / HINT

NOTICE:

• Always use a new grommet and valve core when installing the tire pressure warning valve and transmitter.
• Check that the washer and nut are not damaged, and replace them if necessary.
• Make sure not to damage the urethane covered backside of the tire pressure warning valve and transmitter (the surface opposite to the side with the ID code) with anything sharp.
• Write down the ID number before installation.
• Check that there is no oil, water or lubricant around the rim hole, tire pressure warning valve and transmitter, washer and nut. Failing to do so may result in improper installation.
• Use only a specified tire valve cap. If an unspecified tire valve cap is used, it may seize to the tire pressure warning valve and transmitter.

PROCEDURE

1. INSTALL TIRE PRESSURE WARNING VALVE AND TRANSMITTER

(a) Install a new grommet to the tire pressure warning valve and transmitter.

NOTICE:

A new tire pressure warning valve and transmitter comes with a grommet installed. Make sure not to install an extra grommet.

(b) Write down the 7-digit transmitter ID number shown in the illustration.

*a Printed Surface *b 7-digit Transmitter ID Number

(c) Insert the tire pressure warning valve and transmitter with grommet from the inside of the rim.

NOTICE:

• Make sure that the tire pressure warning valve and transmitter is installed so that the printed surface can be seen. If the tire pressure warning valve and transmitter is installed upside down, it may be damaged or fail to transmit signals when driving at high speeds.
• Check that there is no deformation or damage to the tire pressure warning valve and transmitter.
• Check that there is no foreign matter on the grommet and around the rim hole.

(d) Install the washer to the tire pressure warning valve and transmitter from the outside of the rim, and using an 11 mm deep socket wrench, tighten the nut. Torque: 4.0 N·m {41 kgf·cm, 35 in·lbf} NOTICE: No further tightening is required once the nut is tightened to the specified torque. Check that there is no foreign matter on the grommet, washer and nut.

	Area for Tire Pressure Warning Valve and Transmitter

NOTICE:

• Position the main body of the tire pressure warning valve and transmitter in the area shown in the illustration.
• If the tire pressure warning valve and transmitter is positioned outside this area, it will interfere with the tire bead and may be damaged.

(f) Apply a sufficient coat of soapy water or equivalent to the tire bead and rim.

NOTICE:

Do not apply soapy water or equivalent directly to the tire pressure warning valve and transmitter.

(g) Using a mounting machine, install the tire to the disc wheel.

NOTICE:

• Make sure that the tire bead and mount tool do not interfere with the tire pressure warning valve and transmitter.
• Make sure that the tire pressure warning valve and transmitter is not clamped by the bead and rim.

(h) Install a new valve core.

(i) Inflate the tire to the specified tire inflation pressure.

(j) After the tire is inflated, the nut may be loose. Using an 11 mm deep socket wrench, retighten the nut to the specified torque.

Torque:

4.0 N·m {41 kgf·cm, 35 in·lbf}

NOTICE:

No further tightening is required once the nut is tightened to the specified torque.

(k) Check the surroundings of the tire pressure warning valve and transmitter for air leaks with soapy water or equivalent.

(1) If air is leaking from the valve core, press the valve core several times to remove foreign matter. Replace the valve core as necessary.

(2) If air is leaking from around the tire pressure warning valve and transmitter, check if the grommet, washer and nut are not deformed, damaged or contaminated with foreign matter. Replace the grommet, washer or nut as necessary.

(l) Install the tire valve cap.

2. REMOVE TIRE PRESSURE WARNING VALVE AND TRANSMITTER

(a) Remove the tire valve cap.

NOTICE:

Keep the removed tire valve cap.

(b) Remove the valve core to release the air from the tire.

NOTICE:

Make sure that a sufficient amount of air has been released.

(c) Using an 11 mm deep socket wrench, remove the nut and washer.

(d) Drop the tire pressure warning valve and transmitter with grommet into the tire.

HINT:

The grommet may remain attached to the rim.

(e) Using a tire remover, remove the tire from the disc wheel. NOTICE: Be careful not to damage the tire pressure warning valve and transmitter due to interference between the valve and the tire bead. Set the tire remover shoe as shown in the illustration.

*1 Tire *a Shoe *b 10 to 20 mm (0.394 to 0.787 in.)

(f) Take out the tire pressure warning valve and transmitter with grommet from the tire.

(g) Remove the grommet from the tire pressure warning valve and transmitter.
