<<C>> SEAL/SEAL WASHER REMOVAL
CAUTION
• Do not vary the angle of valve except at mounting on
the rim. If varying the angle over and over, it may cause
breakage of antenna plate resulting in the failure of
TPMS transmitter.
• Use a soft tool to remove the grommet and washer to
prevent scratching the valve of the TPMS transmitter.
1. Hold the TPMS transmitter and the seal washer, then extract
it, this also extracts the seal. Take care to not damage the
valve thread.
2. Clean the TPMS transmitter and the valve stem holding the
valve as shown. Take care to support the rear of the valve
with a thumb so that there is no movement of the stem.

>>A<< SEAL/SEAL WASHER/TPMS TRANSMIT-
TER/NUT INSTALLATION
CAUTION
When installing a new seal and seal washer, make sure to
support the valve stem base with a thumb so that there is
no movement of the stem. Otherwise, the stem may pro-
trude resulting in the breakage of antenna plate.
1. Insert these up to the base of the TPMS transmitter, making
sure to secure the valve base with a thumb, as shown.
Wipe the seal and threading.

CAUTION
• Visually check that TPMS transmitter is not deformed
or damaged.
• When installing the TPMS transmitter, be sure the rim,
seal valve and nut are clean.
• Ensure the grommet is located inside the valve hole
before installing the nut.
• While installing the nut, push the TPMS transmitter to
maintain the lower lip of the transmitter case is in con-
tact with the rim without clearance.
• While installing the valve nut, ensure the tool is kept
aligned to the valve and the valve hole.
• After installing the nut, check that the seal is com-
pressed and seal washer is bend.
2. Install the valve, in the valve hole, without modifying the
angle of the stem (retain position of delivery). The laser
marking should be visible at the operator.
3. When the valve is completely inserted, maintain the TPMS
transmitter in contact with the rim, then screw manually the
nut until the contact with the wheel.
4. While maintaining the TPMS transmitter contact with the rim
by applying pressure to the back of the valve, slightly press
on the cap to wards the center of the wheel in order to adapt
the angle of the valve/TPMS transmitter to the profile of the
rim.
It is mandatory to guarantee the contact of the housing unit
on the rim drop center.

5. While maintaining the TPMS transmitter and valve in
position, screw the nut with a torque wrench.
Take care that the wrench socket is correctly inserted on the
nut.
Specified torque: 8.0
± 0.5 N⋅ m (71 ± 4 in-lb)
.
>>B<< TIRE BEAD MOUNTING
1. Prepare the tire and fix the rim as usual.
2. Put the tire on the rim, so that the cross point of the belt with
the rim is approximately 20 cm (7.9 inch) away from the
valve.
3. Engage the shoe and make sure that 20 cm (7.9 inch) is
maintained between the cross point and the valve.
The arrow shows the direction of rotation of the wheel.

4. Turn the wheel in order to engage all the first side of the tire.
NOTE: The standard shoes can pass over the sensor with-
out damaging it.
5. Put the second side of the tire in position, so that the cross
point of the belt with the rim is approximately 20 cm (7.9
inch) away from the valve. The curved arrow shows the
direction of rotation of the wheel.
6. Turn the wheel in order to engage all of the second side of
the tire.
NOTE: The standard shoes can pass over the sensor with-
out damaging it.

>>C<< TIRE PRESSURE INFLATION/NUT
RETIGHTENING
CAUTION
After tire inflation, retighten the valve nut to 8.0
± 0.5 N⋅ m
(71
± 4 in-lb). This is necessary, because the TPMS trans-
mitter is secured to the wheel with the valve nut and rub-
ber grommet. The rubber grommet will be depressed by
tire pressure or deteriorate over a period of time, which
requires the valve nut to be retightened.
Inflate tire to required pressure, then retorque the valve nut to
8.0
± 0.5 N⋅ m (71 ± 4 in-lb).
