CHASSIS AND BODY MAINTENANCE
Revision: 2006 January2006 M35/M45
Before installing the balance weight, be sure to clean the
mating surface of the 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 balance weight value)
Note that balance weight value must be closer to the calculated
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 at right.
b. When installing balance weight to road wheels, set it into the
grooved area on the inner wall of the road wheel as shown in the
figure 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 unreusable; 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 7.5 g (0.26 oz) each or below.
If either residual unbalance value exceeds 7.5 g (0.26 oz), repeat installation procedures.
Wheel balance (Maximum allowable unbalance):
SMA054D
SEIA0271E
Maximum allowable
unbalanceDynamic (At rim flange) Less than 7 g (0.25 oz) (one side)
Static (At rim flange) Less than 14 g (0.50 oz)

Tire RotationNLS00088
After rotation the tires, adjust the tire pressure.
Retighten the wheel nuts when the vehicle has been driven for
1,000 km (600 miles) (also in cases of a flat tire, etc.).
CAUTION:
Do not include the T-type spare tire when rotating the tires.
When installing wheels, tighten them diagonally by dividing
the work two to three times in order to prevent the wheels
from developing any distortion.
Checking Brake Fluid Level and LeaksNLS00089
If fluid level is extremely low, check brake system for leaks.
Checking Brake Lines and CablesNLS0008A
Check brake fluid lines and parking brake cables for improper
attachment, leaks, chafing, abrasions, deterioration, etc.
Changing Brake FluidNLS0008B
1. Drain brake fluid from each bleed valve.
2. Refill until new brake fluid comes out from each bleed valve.
Use same procedure as in bleeding hydraulic system to refill
brake fluid.
Refer to BR-11, "
Bleeding Brake System" .
Refill with recommended Genuine Nissan Super Heavy Duty
Brake Fluid or equivalent DOT 3 (US FMVSS No. 116).
Refer to MA-12, "
RECOMMENDED FLUIDS AND LUBRI-
CANTS" .
Never reuse drained brake fluid.
Be careful not to splash brake fluid on painted areas.Tightening torque of wheel nut

Fuse NKS004DZ
If fuse is blown, be sure to eliminate cause of malfunction before
installing new fuse.
Use fuse of specified rating. Never use fuse of more than speci-
fied rating.
Do not partially install fuse; always insert it into fuse holder prop-
erly.
Remove fuse for “ELECTRICAL PARTS (BAT)” if vehicle is not
used for a long period of time.
Fusible Link NKS004E0
A melted fusible link can be detected either by visual inspection or by
feeling with finger tip. If its condition is questionable, use circuit
tester or test lamp.
CAUTION:
If fusible link should melt, it is possible that critical circuit
(power supply or large current carrying circuit) is shorted.
In such a case, carefully check and eliminate cause of mal-
function.
Never wrap outside of fusible link with vinyl tape. Important:
Never let fusible link touch any other wiring harness, vinyl
or rubber parts.
Circuit Breaker NKS004E1
The PTC thermistor generates heat in response to current flow. The
temperature (and resistance) of the thermistor element varies with
current flow. Excessive current flow will cause the element's temper-
ature to rise. When the temperature reaches a specified level, the
electrical resistance will rise sharply to control the circuit current.
Reduced current flow will cause the element to cool. Resistance falls
accordingly and normal circuit current flow is allowed to resume.
