Removal & Installation
 
 
REMOVAL
 
 
1. Remove tire assembly. Refer to Removal and Installation.
2. Remove valve cap, valve core and then deflate tire.
noteIf the tire is reused, apply a matching mark to the position of the tire road wheel valve hole for the purpose of wheel balance adjustment after installation.
3. Use the tire changer and disengage the tire beads.
cautionBe sure not to damage the road wheel or tire pressure sensor.
4. Apply bead cream or an equivalent to the tire beads.
5. Turn tire so that valve hole is at bottom and bounce so that tire pressure sensor is near valve hole. Carefully lift tire onto turntable and position valve hole (and tire pressure sensor) 270 degrees from mounting/dismounting head .
cautionBe sure not to damage the road wheel and tire pressure sensor.
6. Remove mounting screw , and then remove tire pressure sensor from valve .
7. Cut the part of valve, using a pliers cutters (B).
cautionBe sure not to damage the road wheel.
8. Remove the valve from road wheel , using a valve inserter (A).
caution
  • Be sure not to damage the road wheel.
  • Pull the valve straight through the rim hole perpendicularly to the rim hole.
 
 
INSTALLATION
cautionNever loosen the mounting screw if the tire pressure sensor and valve are assembled.
 
 
1. When reusing the tire pressure sensor, install the valve to the tire pressure sensor, follow the procedure below.
(1) Insert the tire pressure sensor to the roll pin of valve .
cautionNever reuse valve.
(2) Install mounting screw .
: 1.4 ± 0.1 N·m (0.14 ± 0.01 kg-m, 12.4 ± 0.8 in-lb)
cautionNever reuse mounting screw.
2. Spray water or immerse the valve into water, before mounting in the area indicated shown in the figure.
3. Install the tire pressure sensor assembly, follow the procedure below.
(1) Set the tire pressure sensor assembly to road wheel.
cautionCheck the tire pressure sensor assembly direction, tire pressure sensor assembly must be inserted to the rim of road wheel as shown figure.
(2) Install the tire pressure sensor assembly to road wheel , using a valve inserter (A).
caution
  • Be sure not to damage the road wheel.
  • Pull the valve straight through the rim hole perpendicularly to the rim hole.
  • Avoid any contact of the tire pressure sensor with the rim well and valve with the rim hole counter bore during insertion.
  • Insert tire pressure sensor assembly all the way to the road wheel.
  • Check that tire pressure sensor assembly contacts horizontally with road wheel.
  • Check the tire pressure sensor assembly direction, tire pressure sensor assembly must be inserted to the rim of road wheel as shown figure.
  • If the position is not correct, rotate the tire pressure sensor assembly to the correct position, using a valve inserter.
4. Apply bead cream or an equivalent to the tire beads.
5. Install the tire inside beads onto the road wheel in the position shown in the figure.
6. Set the tire onto the turntable so that the tire changer arm is at a position approximately 270 degrees from the tire pressure sensor .
cautionBe sure that the arm does not contact the tire pressure sensor.
7. Install the tire outer side beads onto the road wheel.
cautionWhen installing, check that the tire does not turn together with the road wheel.
8. Check the tire pressure for all wheels and adjust to the specified value. Refer to Tire Air Pressure.
noteBefore adding air, align the tire with the position of the matching mark applied at the time of removal.
9. Install tire to the vehicle. Refer to Removal and Installation.
10. Perform tire pressure sensor ID registration. Refer to Work Procedure.
