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 tire well, and remove top side of tire. Reach inside the
tire and remove the transmitter.
6. Remove the second side of the tire as normal.
INSTALLATION
1. Place first side of tire onto rim.
2. Apply suitable silicone lubricant to new transmitter seal then install seal on transmitter. Refer to MA-10
.
NOTE:
Always replace the seal after every disassembly.
