Wheel Unit Installation Note

1. Insert the wheel unit valve into the valve hole so

that the polyurethane foam side faces the rim.

Note

• Maintain the wheel unit in contact with the

rim, then start manually to screw the valve
nut for a few turns.

2. Install the nut from the outer side of the wheel.
3. Tighten the valve nut slowly (15 rpm max.) to 8.0

N·m {82 kgf·cm, 71 in·lbf} in one rotation.

Caution

• Do not retighten the valve nut after the

initial operation.

4. Set the tire changer so that it is 45

° away (point A)

from the valve hole.

Caution

• Do not position the tire changer near the

tire valve to avoid any damage to the
wheel unit.

5. Fill the tire with air and verify the valve nut

tightening torque.

Caution

• To prevent damage to the valve area of

the wheel unit or charging loss during air
pressure adjustment, use a type B tool
