Pitting occurs because of uneven rotation of race
and bearing surfaces
The surface peels because of uneven rotation of
the race and bearing surfaces
Chipping or cracking of cage or roller edges
When large load is applied, race and roller
contact surfaces compress, formingindentations
Instead of rolling along race surface, rollers slide,
thus damaging surface
Damage or wear caused by minute particles
adhering to surfaces results in rough movement
and such high temperatures that parts of surface
melt
Appears on various areas of the bearing
Wear of surface areas caused by friction
Grease discoloration results from grease
deterioration which causes particles of
pigment contained in grease to adhere
to surfaces
Heat discoloration will appear
as a deep brown on purple

o-2LUBRICATION AND MAINTENANCE - General Information
GENERAL INFORMATIONNGQPA--Maintenance and lubrication service recommenda-
tions have been compiled to provide maximum
protection for the vehicle owner’s investment
against all reasonable types of driving conditions.
Since these conditions vary with the individual
vehicle owner’s driving habits, the area in which the
vehicle is operated and the type of driving to which
the vehicle is subjected, it is necessary to prescribe
lubrication and maintenance service on a time
frequency as well as mileage interval basis.
Oils, lubricants and greases are classified and
graded according to standards recommended by theSociety of Automotive Engineers (SAE), the Amer-
ican Petroleum Institute (API) and the National
Lubricating Grease Institute
(NLGI).MAINTENANCE SCHEDULES
Information for service maintenance is provided
under “SCHEDULED MAINTENANCE TABLE”.
Three schedules are provided; one for “Required
Maintenance”, one for “General Maintenance” and
one for “Severe Usage Service”.
Item numbers in the “SCHEDULED MAINTE-
NANCE TABLE” correspond to the item numbers in
the “MAINTENANCE SERVICE” section.
SEVERE SERVICEVehicles operating under severe service conditions
will require more frequent service.
Component service information is included in
appropriate units for vehicles operating under one ormore of the following conditions:
1.Trailer towing or police, taxi, or commercial type
operation2. Operation of Vehicle
(1) Short-trip operation at freezing temperature
(engine not thoroughly warmed up)
(2) More than 50% operation in heavy city
traffic during hot weather above
32°C (90°F)(3) Extensive idling
(4) Driving in sandy areas
(5) Driving in salty areas
(6) Driving in dusty conditions
ENGINE OIL
The SAE grade number indicates the viscosity of
engine oils, for example, SAE 30, which is a single
grade oil. Engine oils are also identified by a dual
number, for example, SAE
lOW-30, which indicates
a multigrade oil.
The API classification system defines oil perform-
ance in terms of engine usage. Only engine oil
designed “For Service SG” or “For Service
SGKD”,when available, should be used. These oils contain
sufficient chemical additives to provide maximum
engine protection. Both the SAE grade and the API
designation can be found on the container.Caution
Test results submitted to EPA have shown thatlaboratory animals develop skin cancer after
prolonged contact with used engine oil. Accor-
dingly, the potential exists for humans
to de-
velop a number of skin disorders, including
cancer, from such exposure to used engine oil.
Care should be’ taken, therefore, when changingengine oil, to minimize the amount and length of
exposure time to used engine
pi! on your skin.
Protective clothing and gloves, that cannot be
penetrated by oil, should be worn. The skin
should be thoroughly washed with soap and
water, or use waterless hand cleaner, to removeany used engine oil. Do not use gasoline,
thinners, or solvents.
GEAR LUBRICANTSThe SAE grade number also indicates the viscosity
of Multi-Purpose Gear Lubricants.
The API classfication system defines gear lubricants
in terms of usage. Typically gear lubricants conform-ing to API
GL-4 or GL-5 with a viscosity of SAE
75W-85W are recommended for manual transaxle.
LUBRICANTS
- GREASES
Semi-solid lubricants, bear the NLGI designation andare further classified as grades 0, 1, 2, 3 etc.
Whenever “Chassis Lubricant” is specified, Multi-
Purpose Grease,
NLGI grade 2 should be used.
MOPAR Multi-Mileage Lubricant, P&t Number
2525035 or equivalent, meets these requirement
and is recommended.
FUEL USAGE STATEMENT
Use gasolines having a minimum anti-knock index
(Octane Value) of 87,
(R + M)/2. This designation is
comparable to a Research Octane Number of 91.
Unleaded gasolines only must be used in vehicles
equipped with catalyst emission control systems.
All vehicles, so equipped, have labels located on the
instrument panel and on the back of fuel filler lid that
state, “UNLEADED GASOLINE ONLY”. These vehi-
cles also have fuel filler tubes especially designed toaccept the smaller diameter unleaded gasoline
dispensing nozzles only.
MATERIALS ADDED
TO FUELIndiscriminate use of fuel system cleanng agents
should be avoided. Many of these materials in-
tended for gum and varnish removal may contain
highly active solvents or similar ingredients that can
be harmful to gasket and diaphragm materials usedin fuel system component parts.

’ ~ “.SELECTION OF LUBRICANTS
ENGINE OIL
Engine oil should be used which conform to the requirements
of the API classification “For Service SG” or “For Service
SGKD”, and have the proper SAE grade number for the
expected temperature range.
Caution
Nondetergent or straight mineral oil must never be used.
Energy Conserving Oil
In order to improve fuel economy and conserve energy new,
lower friction engine oils have been developed. These oils are
readily available and can be identified by such labels as “EnergyConserving”,“Energy Saving”,“Improved Fuel Economy”,
etc.
/”SAE
5W-20 Not recommended for sustained
high speed vehicle operation.**SAE
5W-30 may be used for operation in very

concentration
ExampleThe safe operating temperature is
- 15°C (5°F) when the measured specific gravity is 1.058 at the coolant
temperature of
20°C (68°F).
Cautions1. If the concentration of the coolant is below 30%, the anti-corrosion property will be adversely
affected. In addition, if the concentration is above 60%, both the anti-freeze and engine cooling
properties will decrease, affecting the engine adversely. For these reasons, be sure to maintain theconcentration level within the specified range.
2. Do not use a mixture of different brands of anti-freeze.

place lever in“N” Neutral position. This operation is
necessary to be sure that fluid level check is accurate.
4.Before removing dipstick, wipe all dirt from area arounddipstick. Then take out the dipstick and check the
condition of the fluid.
The transaxle should be overhauled under the following
conditions.l If there is a “burning” odor.
l If the fluid color has become noticeably blacker.
l If there is a noticeably great amount of metal
particles in the fluid.
5.Check to see if fluid level is in “HOT” range on dipstick.If fluid level is low, add ATF until level reaches “HOT”
range.Low fluid level can cause a variety of conditions
because it allows pump to take in air along with fluid. Airtrapped in hydraulic circuit forms bubbles which make
fluid spongy. Therefore, pressures will be erratic.
Improper filling can also raise fluid level too high. Whentransaxle has too much fluid, gears churn up foam and
cause same conditions which occur with low fluid level,resulting in accelerated deterioration of ATF.
transmission fluid.
In either case, air bubbles can cause overheating, fluid
oxidation, which can interfere with normal valve, clutch,and servo operation. Foaming can also result in fluid
escaping from transaxle vent where it may be mistakenfor a leak.
6. Be sure to examine fluid on dipstick closely.lO.AUTOMATIC TRANSAXLE (Change fluid)
Drain the fluid and check whether there is any evidence of
contamination.
Replenish with new fluid after the cause of any contamina-tion has been corrected.
