LUBRICATION
AND
MAINTENANCE

• A vehicle equipped with SAE approved sling-type
towing equipment can be used (Fig. 10). However,
many vehicles are equipped with air dams, spoilers, and/or ground effect panels. In this case a wheel-lift
towing vehicle or a flat-bed hauling vehicle is recom­ mended (Fig. 10). If a flat bed device is used, the ap­
proach angle should not exceed 15 degrees.
GROUND CLEARANCE The lifted wheels of the disabled vehicle should be
a minimum of 10 cm (4 in.) off the ground. Make
sure there is enough clearance at the opposite end.
This is critical when towing over rough terrain. If necessary, the rear ground clearance can be in­creased by removing the wheels from the lifted end
and then towing with the lifted end closer to the
ground. If the rear wheels are removed, secure the
brake drums. A 20 cm (8 in.) ground clearance must
be maintained between brake drums or rotors and the ground.
SAFETY PRECAUTIONS The following safety precautions must be consid­
ered when preparing for and during a vehicle towing operation:
• Remove exhaust pipe tips that interfere with the
tow sling and crossbar • Padding should be placed between the tow sling/
crossbar and any painted surfaces
• If the vehicle is damaged, secure the loose and pro­
truding parts
• Always use a safety chain system that is indepen­ dent of the lifting and towing equipment
• When placing tow hooks on the rear axle, position them so they do not damage the brake tubing or
hoses
• Do not allow any of the towing equipment to con­
tact the fuel tank
• Do not tow the vehicle by connecting to the front
or rear shock absorbers
• The operator should not go under a vehicle while
it is lifted by the towing equipment. The vehicle
should first be supported by safety stands
• Do not allow passengers in a vehicle being towed
• Observe all state and local laws involving warning signals, night illumination, speed, etc.
• Do not exceed a towing speed of 48 km/h (30 mph)
• Avoid towing distances of more than 24 km (15
miles) whenever possible • Do not attach tow chains or a tow sling to a
bumper, the steering linkage, the universal joints, or a drive shaft
REAR-END RAISED TOWING It is recommended that the rear-end raised towing
method be used. Vehicles can be towed with the front
wheels on the ground for extended distances at speeds not exceeding 48 km/h (30 mph) (Fig. 11). (1) Attach the J-hooks around the axle shaft tubes
outboard of the rear springs. (2) Position and center the sling under and for­
ward of the rear bumper. (3) Attach safety chains (with pads) at each end of
the rear bumper.
(4) Turn the ignition switch to the OFF position to
unlock the steering wheel. (5) Clamp the steering wheel with the front wheels
in the straight ahead position.

CAUTION:
Do not use the steering
column
lock
to

secure
front
wheel
in the straight-ahead
position.

(6) Shift the transmission to NEUTRAL.

(2) Route the J-hooks and tow chains over the
steering linkage outboard of the coil spring.
(3) Attach the J-hooks to the outer end of the
lower suspension arms.
(4) Raise the vehicle.
(5.) Attach the safety chains to the disabled vehicle
at the frame rails.

AND
MAINTENANCE
0 - 23 GEAR SHIFTER BOOTS
Inspect the shifter boots periodically for stone and
heat damage. Replace, if necessary.
SEVERE DRIVING CONDITIONS The interval between the transmission drain and
refill maintenance should be decreased to:
• NV4500 manual transmission—every 29 000 km (18,000 miles)
• Automatic transmission—every 19 000 km (12,000
miles)
A severe driving condition includes:
• Extended operation with heavy cargo loads
• Driving in deep mud or snow
• Off-road operation (4WD)
• Trailer towing
• Operation as a commercial vehicle
• Snow plowing
MANUAL TRANSMISSIONS

INSPECTION/LUBE
OIL
LEVEL
The transmission should be checked for leaks when
other service is necessary under the vehicle. To check
the lube oil level, remove the fill hole plug (Fig. 2 ). If the level is below the bottom of the fill hole, raise
the level to the bottom of the fill hole with:
• Castrol Syntorq for NV4500 transmissions
• SAE 5W-30 engine oil (API Service SG, SG/CD or
SG/CE) for Getrag 360 transmissions.

The condition of the ATF also should be deter­
mined. If the ATF is dark in color and has a strong odor, the fluid should be changed. Also the filter should be replaced and the bands adjusted.
The following procedure must be used to check the
automatic transmission fluid (ATF) level.
(1) Position the vehicle on level ground.
(2) Operate the engine at idle speed.
(3) Apply the parking brake.
(4) Place the gear selector in N (neutral).
(5) Remove the dipstick from the tube. Wipe it
clean and determine if the ATF is hot or warm.
Hot ATF has a temperature of approximately
82°C (180°F). Warm ATF is when its temperature
is between 29-52°C (85-125°F). (6) Wipe the dipstick clean and completely insert it
into the tube. Remove the dipstick from the tube and
observe the ATF level.
(7) If the ATF is hot, the level should be in the
crosshatched area that is marked OK.
(8) If the ATF is warm, the level should be be­
tween the two dimples.

Sure-Grip
Differential
Components
The action
of a
standard differential will allow
the

rear wheels
to
rotate
at
different speeds when
the ve­

hicle
is
turning. This differential will divide
the en­
gine torque equally between them. This
is a
desirable
and
normal function
of a
differential.
A

Sure-Grip differential transfers additional engine
torque
to the
rear wheel that
has the
better traction surface.
The
Sure-Grip differential allows
the
driving
wheel with better traction
to
develop more driving
torque than
the
other wheel.
The
Sure-Grip
is not a
locking type differential.
IDENTIFICATION Raise both rear wheels
off the
surface
and
rotate
them.
If
both rear wheels rotate
in the
same direc­
tion,
the
vehicle
is
equipped with
a
Sure-Grip differ­ ential. Another method
of
identification
is by

removing
the
housing cover fill hole plug. Examine (with
a
flashlight)
the
differential case components
through
the
lubricant fill hole.
SERVICE INFORMATION When Sure-Grip differential service
is
necessary,
both rear wheels must
be
raised
off the
surface
so
they
are
free
to
rotate.
A Sure-Grip differential case
is not
repairable.
If defective,
it
must
be
replaced
as a
complete
unit only.
Do not
attempt
to
disassemble
and re­

pair
the
case components.
Follow
the
same procedure outlined under Stan­
dard Differential
for
Removal
and
Installation.
DIFFERENTIAL TEST

CAUTION:
Whenever
a
rear axle
is
being
serviced,
RAISE
BOTH
REAR
WHEELS
off the
surface.
A Sure-Grip differential
can be
tested without
re­

moving
the
differential case from
the
housing.
(1) Position
the
vehicle
on a
hoist with
the
ignition

OFF.
Put the
transmission selector lever
in
PARK
(automatic transmission)
or in
first gear (manual
transmission).
(2) Attempt
to
manually rotate each rear wheel.
(3)
If
difficult
to
manually rotate either wheel,
the

Sure-Grip differential
is
functioning normally.
If

easy,
the
differential
is not
functioning normally
and
should
be
replaced.
A Sure-Grip differential case
is not

DIFFERENTIAL NOISE Noise complaints involving
a
Sure-Grip should
be

evaluated
to
determine
the
source
of the
noise.
If a

noise occurs while
the
vehicle
is
turning,
the
proba­
ble cause
is
incorrect
or
insufficient gear lubricant. The drain

STARTER SYSTEM DIAGNOSTIC INSPECTIONS
Before removing any unit from the starter motor
system for repair, perform the following inspections:

BATTERY
INSPECTION
To determine condition of the battery, perform the
testing procedure outlined in the Battery Section.

WIRING INSPECTION
Inspect wiring for damage. Inspect all connections
at the starter motor solenoid, park/neutral position
switch (if equipped), back-up lamp switch connector,
ignition/start switch, and battery (including all
ground connections). Clean and tighten all connec­
tions as required.

SOLENOID, RELAY
AND
IGNITION/START

SWITCH
INSPECTION
Inspect the solenoid, relay and switch to determine
their condition. Also, if equipped with automatic
transmission, inspect condition of the park/neutral position switch. Testing information can be found in
the following pages.
If the following components are working properly
remove the starter motor and follow procedures in
the Testing Section. • battery wiring

COLD CRANKING TEST
(1) Battery must first pass load and voltage drop
tests and be fully charged before proceeding. Refer to Battery Test Procedures. (2) Connect a suitable volt-ampere tester to the
battery terminals (Fig. 2). Refer to the operating in­ structions provided with the tester being used.

and connect to ground.
(6) Rotate and hold the ignition switch (key) in the
START position. Note cranking voltage and amper­
age.
(a) If voltage reads above 9.6 volts and amperage
draw reads above (220 amps gas engine) (550 amps
diesel) go to Starter Feed Circuit Tests. (b) If voltage reads 12.5 volts or greater and am-
perate reads 0 to 10 amps, go to Starter Control Circuit Tests.
A cold engine will increase starter motor cur­
rent.

STARTER
FEED
CIRCUIT TESTS
-
(W0LTAGE
DROP
METHOD)
The voltage drop tests will determine if there is ex­
cessive resistance in the high current circuit. When
performing these tests, it is important that the volt­ meter be connected to the terminals that the cables are connected to instead of to the cables themselves.
For example, when testing between the battery and
solenoid, touch the voltmeter test probes to the bat-
