Transmitter (Pressure Sensor): Removal and Installation

Removal

1) Remove wheel and tire using power tool.
2) Deflate tire. Unscrew transmitter retaining nut and allow transmitter to fall into tire.
3) Gently bounce tire so that transmitter falls to bottom of tire. Place wheel and tire assembly on tire changing machine and break both tire beads. Ensure that the transmitter remains at the bottom of the tire while breaking the bead.





4) Turn tire so that valve hole is at bottom, and gently bounce the tire to ensure transmitter is near valve hole. Carefully lift tire onto turntable and position valve hole (and transmitter) 270 degrees from mounting/dismounting head.





5) Lubricate the tire well with a suitable non-silicone lubricant, and remove top side of tire. Reach inside the tire and remove the transmitter.
