REMOVAL
(1) Remove the tire and wheel assembly from the
vehicle. (Refer to 22 - TIRES/WHEELS - REMOVAL)
CAUTION: When removing the stick on balancing
weights from the wheel, do not use an abrasive
cleaner or a cleaner which will damage the protec-
tive finish on the wheel.
(2) Remove the balancing weights from the wheel.
NOTE: The cap used on this valve stem contains an
O-ring seal to prevent contamination and moisture
from entering the valve stem. Retain this valve stem
cap for re-use. Do not substitute a regular valve
stem cap in its place.
(3) Remove the cap from the valve stem.
NOTE: The valve stem used on this vehicle is made
of aluminum and the core is nickel plated brass.
The original valve stem core must be reinstalled
and not substituted for a valve stem core made of a
different material. This is required to prevent corro-
sion in the valve stem caused by the different met-
als.
(4) Using the appropriate tool, remove the core
from the valve stem (Fig. 15).

(5) Let the tire fully deflate.
CAUTION: The pressure
removed from the wheel and dropped into the tire
prior to breaking the bead and dismounting the tire.
Failure to do this will greatly increase the risk of
damaging the pressure transducer when servicing
the tire.
(6) Remove nut mounting valve stem of pressure
sensor/transmitter to the wheel (Fig. 16). Drop sen-
sor/transmitter into tire.

CAUTION: When breaking the top and bottom bead
of the tire off the wheel, care must be used so the
bead breaking mechanism on the tire changer does
not damage the wheel. This includes the surface of
the wheel flange on the inside of the wheel.
(7) Using the tire changer manufacturers proce-
dure, first break down the upper bead of the tire.
Then break down the bottom bead of the tire.
CAUTION: When dismounting the upper tire bead
from the wheel, the proper procedure must be used.
Not using the proper procedure will result in dam-
age to the wheel and tire. (Refer to 22 - TIRES/
WHEELS - DISASSEMBLY)
(8) Dismount the upper bead of the tire from the
wheel. The upper bead must be fully dis-
mounted from the wheel to remove the tire
pressure transmitter from the inside of the tire.
The bottom bead of the tire does not need to be
removed from the wheel. (Refer to 22 - TIRES/
WHEELS - DISASSEMBLY)
