LUBRICATION
AND
MAINTENANCE

• Commercial service
When a vehicle is continuously subjected to severe
driving conditions, lubricate:
• Body components
• All the driveline coupling joints
• Steering linkage More often than normal driving conditions

DUSTY
AREAS
With this type of severe driving condition, special
care should be given to the:
• Engine air cleaner filter
• PCV filter
• Crankcase ventilation system
• Brake booster control valve air filter. Verify that the filters and the associated compo­
nents are clean. Also verify that they are functioning
effectively. This will minimize the amount of abra­ sive particles that enter the engine.

OFF-ROAD
(4WD)
OPERATION
After off-road (4WD) operation, inspect the under­
side of the vehicle. Inspect the:
• Tires
• Body structure
• Steering components
• Suspension components • Exhaust system
• Threaded fasteners

HARSH
SURFACE ENVIRONMENTS
After extended operation in harsh environments,
the brake drums, brake linings, and rear wheel bear­ ings should be inspected and cleaned. This will pre­
vent wear and erratic brake action.

ROUTINE MAINTENANCE
The following routine maintenance is recommended
on a monthly basis: TIRES—Inspect the tires for unusual wear/damage.
Determine if the inflation pressure is adequate for
the vehicle load. BATTERY—Inspect and clean the terminals.
Tighten the terminals if necessary. FLUIDS—Determine if the component fluid levels
are acceptable. Add fluid, if necessary. LIGHTS/ELECTRICAL—Test all the electrical sys­
tems in the vehicle for proper operation. It is also recommended that the engine oil and the
washer fluid level be determined at each fuel fill-up.

VEHICLE
NOISE CONTROL
Vehicles with a GVWR of 4 535 kg (10,000 lbs), or
more, are required to comply with Federal Exterior Noise Regulations (Fig. 2).

UNAUTHORIZED
DEFEAT
OF
NOISE
CONTROL COMPONENTS
Federal law prohibits removal, altering or other­
wise defeating any noise control component. This in­
cludes before or after the vehicle is in use. Federal
law also prohibits the use of a vehicle after a noise
control component is defeated.

REQUIRED MAINTENANCE/SERVICE
FOR
NOISE
CONTROL

The following maintenance is required after each
6-month or 9 600 km (6,000 miles) interval. This will
ensure that the vehicle noise control components are
operating properly.

EXHAUST SYSTEM
Inspect exhaust system for exhaust leaks and dam­
aged components. The exhaust hangers, clamps and
U-bolts should be attached and in good condition.
Burned or ruptured mufflers, damaged exhaust pipes should be replaced. Refer to Group 11—Exhaust Sys­
tem/Intake Manifold for service information.

AIR
FILTER
HOUSING/CANISTER
Inspect the air filter assembly for proper fit. Verify
the cover is securely attached to the housing/canis­
ter. Inspect all the air filter housing hoses for con­ nections. The gasket between the air filter housing and throttle body must be in good condition. The air
filter element should be clean and serviced according
to the maintenance schedule.

FUEL
REQUIREMENTS
GASOLINE
ENGINES
All engines require the use of unleaded gasoline to
reduce the effects of lead to the environment. Also unleaded fuel is necessary to prevent damage to the
catalytic converter/02 sensor. The fuel must have a
minimum octane rating of 87 based on the (R + M)/2
calculation method.

CAUTION: UNLEADED FUEL ONLY must
be
used
in

vehicles equipped
with

system.
All
vehicles have reminders
printed
on the
instrument
panel below
the
fuel
gauge
and on the

fuel
filler
door.
The
vehicles also have
fuel
filler

tubes
that
are
specially designed
to
accept only
the

CLASSIFICATION
OF
LUBRICANTS
Lubricating fluids
and
chassis lubricants
are
clas­
sified according
to
standards recommended
by the:
• Society
of
Automotive Engineers
(SAE)

• American Petroleum Institute
(API)

• National Lubricating Grease Institute (NLGI)
ENGINE
OIL

SAE
VISCOSITY
GRADE
An
SAE
viscosity grade
is
used
to
specify
the
vis­
cosity
of
engine
oil. SAE 30
specifies
a
single viscos­
ity engine
oil.

Engine oils also have multiple viscosities. These
are specified with
a
dual
SAE
viscosity grade which
indicates
the
cold-to-hot temperature viscosity range (Fig.
3).

API
SERVICE
GRADE
The
API
Service Grade specifies
the
type
of
perfor­
mance
the
engine
oil is
intended
to
provide.
The API
Service Grade specifications also apply
to
energy con­
serving engine oils
(Fig. 3).

For maximum gasoline engine protection,
use API

Service Grade
SG,
SG/CD
or
SG/CE engine
oil.

For maximum Diesel engine protection,
use

API Service
CE or
SG/CE engine
oil.

GEAR LUBRICANTS A dual grade
is
also used
to
specify
the
viscosity
of

multi-purpose gear lubricants.
The
API
grade designation identifies gear lubri­
cants
in
terms
of
recommended usage.

If it becomes necessary to use a booster battery and
jumper cables to start an engine, use the following procedure.
J9200-86

(1) Engage the parking brake. Shift the automatic
transmission to PARK (if a manual transmission, shift to NEUTRAL).
(2) Turn off all lights, and all other electrical

loads.

(3)
Observe the battery condition indicator (Fig. 5).
If the battery condition indicator is light/bright col­
ored (or yellow), replace the battery. Do not attempt
to jump start an engine when the condition indi­
cator is light/bright colored (or yellow). If the
condition indicator is dark in the center (but without a green dot), proceed with connecting the jumper ca­

bles.

VEHICLE
TOWING
RECOMMENDATIONS
When it is necessary to tow a Ram Truck, the rec­
ommended method is either:
• the sling-type, rear-end raised towing method; or
• the wheel-lift towing method with a tow dolly lo­
cated under the front wheels. A vehicle with flat-bed hauling equipment can also
be used to transport a disabled vehicle.

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

position.

(6) Shift the transmission to NEUTRAL.

FRONT&#39;END RAISED TOWING If a vehicle cannot be towed from the rear, the
front-end raised towing method normally can be
used (Fig. 12). (1) Center the sling with the bumper and position
it at the frame front crossmember.

lower suspension arms.
(4) Raise the vehicle.
(5.) Attach the safety chains to the disabled vehicle
at the frame rails.
