InspectionEES000J2
ALUMINUM WHEEL
1. Check tyres for wear and improper inflation.
2. Check wheels for deformation, cracks and other damage. If
deformed, remove wheel and check the wheel runout.
a. Remove tyre from aluminum wheel and mount on a tyre balance
machine.
b. Set dial indicator as shown in the illustration.
STEEL WHEEL
1. Check tyres for wear and improper inflation.
2. Check wheels for deformation, cracks and other damage. If
deformed, remove wheel and check the wheel runout.
a. Remove tyre from steel wheel and mount wheel on a tyre bal-
ance machine.
b. Set two dial indicators as shown in the illustration.
c. Set each dial indicator to 0.
d. Rotate wheel and check dial indicators at several points around
the circumference of the wheel.
e. Calculate runout at each point as shown below.
f. Select maximum positive runout value and the maximum nega-
tive value.
Add the two values to determine total runout.
In case a positive or negative value is not available, use the
maximum value (negative or positive) for total runout.
If the total runout value exceeds the limit, replace steel wheel.Wheel runout (Dial indicator value):
Refer to WT-6, "
SERVICE DATA AND SPECIFICA-
TIONS (SDS)"SFA975B
Radial runout = (A + B)/2 : 0.5 mm (0.020 in)
Lateral runout = (C + D)/2 : 0.8 mm (0.031 in)

Balancing Wheels (Adhesion Balance Weight Type)EES000QZ
REMOVAL
1. Remove inner and outer balance weights from the road wheel.
CAUTION:
Be careful not to scratch road wheel during removal.
2. Using releasing agent, remove double-faced adhesive tape from road wheel.
CAUTION:

Be careful not to scratch road wheel during removal.

After removing the double-faced adhesive tape, wipe off traces of releasing agents from road
wheel.
WHEEL BALANCE ADJUSTMENT

If a tyre balance machine has both an adhesion balance weight mode setting and a drive-in weight mode
setting, select and adjust a drive-in weight mode suitable for road wheels.
1. Set road wheel on wheel balancer using the center hole as a guide. Start the tyre balance machine.
2. When inner and outer unbalance values are shown on the wheel balancer indicator, multiply outer unbal-
ance value by 5/3 to determine balance weight that should be used. Select the outer balance weight with
a value closest to the calculated value above and install it to the designated outer position of, or at the
designated angle in relation to road wheel.
CAUTION:

Do not install the inner balance weight before installing the outer balance weight.

Before installing the balance weight, be sure to clean the
mating surface of road wheel.
Indicated unbalance value × 5/3 = balance weight to be installed
Calculation example:
23 g (0.81 oz) × 5/3 = 38.33 g (1.35 oz) = 40 g (1.41 oz) balance
weight (closer to calculated a balance weight value)
Note that a balance weight value must be closer to the calcu-
lated balance weight value.
Example:
37.4 = 35 g (1.23 oz)
37.5 = 40 g (1.41 oz)
a. Install balance weight in the position shown in the figure.
b. When installing balance weights to road wheels, set it into the
grooved area on the inner wall of road wheel as shown in the fig-
ure so that the balance weight center is aligned with the wheel
balancer indication position (angle).
CAUTION:

Always use genuine NISSAN adhesion balance weights.

Balance weights are non-reusable; always replace with
new ones.

Do not install more than three sheets of balance weight.

c. If calculated balance weight value exceeds 50 g (1.76 oz), install
two balance weight sheets in line with each other (as shown in
the figure).
CAUTION:
Do not install one balance weight sheet on top of another.
3. Start wheel balancer again.
4. Install drive-in balance weight on inner side of road wheel in the
wheel balancer indication position (angle).
CAUTION:
Do not install more than two balance weights.
5. Start wheel balancer. Make sure that inner and outer residual
unbalance values are 10 g (0.35 oz) each or below.

If either residual unbalance value exceeds 10 g (0.35 oz), repeat installation procedures.
Wheel balance (Maximum allowable unbalance):
RotationEES000J3

After rotating the tyres, adjust the tyre pressure.

Retighten the wheel nuts when the vehicle has been driven for
1,000 km (600 miles) (also in cases of a flat tyre, etc.).
CAUTION:
When installing wheels, tighten the wheel nuts diagonally
by dividing the work two to three times in order to prevent
the wheels from developing any distortion.
Maximum allowable
unbalanceDynamic (At rim flange) Less than 10 g (0.35 oz) (one side)
Static (At rim flange) Less than 20 g (0.70 oz)
