INSTALLATION
CAUTION / NOTICE / HINT
NOTICE:
- Always use a new bolt, grommet, tubeless tire valve 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) Using a T10 "TORX" socket wrench, install the tire pressure monitor sensor to the new tubeless tire valve with a new bolt.
Torque:
1.2 N·m {12 kgf·cm, 11 in·lbf}
(b) 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.
| (c) Write down the 7-digit transmitter ID number shown in the illustration. |
|
| (d) Insert the tire pressure warning valve and transmitter with grommet from the inside of the rim. NOTICE:
|
|
(e) 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.
(f) Set the tire and disc wheel onto the mounting machine as shown in the illustration.

 | 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.
(g) 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.
(h) 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.
(i) Install a new valve core.
(j) Inflate the tire to the specified tire inflation pressure.

(k) 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.
(l) 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.
(m) Install the tire valve cap.
