Engine Oil

For
maximum
engine
protection under all driving conditions encountered during the recommended

oil
change intervals, it is necessary to use only

"MS"
certified
sequence-tested
oils. The term
"MS"
must appear on the oil container singly or

in
conjunction with other designations. "MS" des­
ignated oils are heavy-duty detergent oils that are
formulated to withstand all service conditions in
modern powerplants. Engine oils designated only
as
"ML"
and/or
"MM"
are not recommended and should not be used except in an emergency when

"MS"
oil is not available. Certified
sequence-tested

engine
oils are described on their containers by

such
phrases as:
meets,
exceeds,
excels, or has
proven superior in the
test
requirements,
test
sequences, MS Service
tests,
standards, and service

requirements,
of automotive manufacturers, auto­
makers,
or car manufacturers for MS service or
Service
MS.
It
may be necessary to change
engine
oil more
frequently than normally recommended, depending upon the type and quality of oil used, the severity
of operation conditions, if the
engine
is used for
short
periods in cold weather, or if the
engine
is allowed to idle for excessive periods.

Always
drain
the crankcase while the
engine
is hot since
dirt
and contaminants are then more
likely
to be held in suspension and therefore
will

drain
out more completely.
Drain
the crankcase as follows:

a.
Position the
drain
receptacle under the
drain

plug.

b.
Remove the
drain
plug using the correct size

wrench.
Be careful of hot oil.
c.
Carefully
clean the
drain
plug. Inspect and

replace
the gasket, if deteriorated.
d.
When the oil has drained, replace and tighten
the crankcase
drain
plug. 12

B

LUBRICATION
Note:
Hard
shifting of the transmission gear in
cold weather is a positive indication that the
lubri­

cant
is of the wrong viscosity or of poor quality

which
allows it to congeal.

B-38.
Optional
4-Speed
Transmission
and
Transfer Case

The
four-speed transmission and transfer case re­

quire
separate lubrication for each unit as
they
have no cross-over oil passage. At each transmission
service check, the
fill
plugs of
both
four-speed

transmission
and transfer case should be pulled
and
the lubricant refilled to level if necessary.

B-39.
Transfer
Case
Linkage

The
transfer case shift linkage should be lubricated

periodically.
All
bearing surfaces that are assembled
with
studs and cotter pins should be disassembled, cleaned, and coated with a
good
waterproof grease.

The
bearing surfaces that cannot be disassembled
should be lubricated with a lubricant that
will
penetrate the bearing
area.
These bearings include
the two on the cross shaft assembly and the
threaded stud.

The
type
of penetrating lubricant recommended is
DuPont
"PM 7", No. 2911, or its equivalent.

B-40.
Brake Master Cylinder

Clean
the top of the
fill
cap and also the housing

area
around it. Remove the cap and observe the
fluid
level. It should be
half
an inch
below
the top
of the fill-hole. If not, add brake fluid to
half
inch
[1,3 cm.]
below
the top of the fill-hole. Use
only heavy-duty brake fluid conforming to speci­
fication
SAE-J-1703.
Be sure to handle the brake

fluid
in clean dispensers and containers that
will
not introduce even the
slightest
amount of other

liquids
or foreign particles. Replace and tighten
the
fill
cap.

B-45.
Tie Rod and Drag
Link
Sockets

The
tie rod and drag
link
sockets
are equipped

with
lubrication
fittings
and should be lubricated

per
specifications given in the
Lubrication
chart: see Item 1. Chassis Bearings.
B-46.
Front
and
Rear Spring
Bushings

The
condition of the spring bushings is indicated
by the alignment of the spring pivot and spring
shackle
bolts.
Check
the alignment of
these
bolts,

and
check that nuts are
tightened
securely.

B-47.
Spring
Shackles

Rubber
bushings are provided on the spring
shackles.
These rubber bushings have no lubrication
fitting and it is very important that
they
never be lubricated.

Conventional Differentials

To
remove the lubricant from the front or
rear
differential,
it is necessary to remove the housing cover. Let the lubricant
drain
out, and then flush
the differential with a flushing oil or light
engine

oil
to clean out the housing
(except
Powr-Lok
or
Trac-Lok
Differentials). Do not use water, steam,
kerosene, or
gasoline
for flushing.

Reinstall
the housing cover, replacing the gasket whenever necessary, torquing the cover
bolts
to 15 to 25 lb-ft. [2,1 a 3,4 kg-m.].
Remove the filler plug, and
refill
the differential
housing as specified in the
Lubrication
Specifica­
tions.

Powr-Lok
or
Trac-Lok Differential

Some vehicles may be equipped with the
Powr-Lok

or
Trac-Lok
Differential as optional equipment.
Special

lubricants
must
not be used. Use only
'Jeep*

Part
No. 94557.

Powr-Lok
or
Trac-Lok
differentials may be cleaned
only by disassembling the unit and wiping with
clean
rags. Do not flush the unit. Refer to Sec­
tion N.

B-54.
Front Axle Universal Joint
—
Lube

Check
the level of the front axle universal joint
lubricant
at each front wheel by removing the
fill-hole plug. The lubricant should be level with
the fill-hole. If required, add lubricant as specified

in
Lubrication
Specifications.

B-55.
Front
Axle
Universal
Joint
— Service

On
all 4-wheel drive vehicles the front axle
uni­

versal
joint should be serviced by removing the shaft and thoroughly cleaning the universal joints

and
housing. For the correct procedures, refer to
Section M. 16

'Jeep'
UNIVERSAL SERIES SERVICE
MANUAL

B
Reinstall
the axle shafts, and
refill
the housings to

specified in
Lubrication
Specifications.

B-56.
Front
Axle Wheel Bearings

To
lubricate the wheel bearings, it is necessary
to remove, clean, repack, and adjust them. When
front wheel hubs and bearings are removed for
lubrication,
they should be thoroughly washed in a
suitable cleaning solvent. The bearings should be
carefully
dried and then given a thorough cleaning

and
inspection. Use a clean brush to remove all

particles
of old lubricant from bearings and hubs.

After
the bearings are cleaned, inspect them for
pitted races and rollers. Also, check the hub oil
seals.

Note:
Wheel bearing lithium base lubricants are
used at the factory for
initial
fill
of
these
bearings.
When
lithium base and sodium base lubricants are

mixed,
the result is a thinned-out mixture that
can
bleed through seals. It is therefore important
that lubricants with the correct base be used when

lubricating
the wheel bearings.
Should
leaks occur at wheel bearing seals, the leaks

may
be caused by a mixture of two
types
of
lubri­

cants.
In such cases, the old lubricant should be
completely removed before new lubricant is added.

Wheel
bearings should be thoroughly cleaned,
lubricated
with lithium base and reinstalled.

Repack
the bearing
cones
and rollers with grease

and
reassemble hub in the reverse order of the
disassembly. Test the bearing adjustment as out­

lined
in Section Q.

B-57.
Rear
Axle Wheel Bearings

The
Rear
wheel bearings an early models equipped

with
lubrication fittings with a vent opening
through the housings above each fitting should be
lubricated
sparingly, each
2,000
miles
[3.200
km.].

Use
a hand compressor and wheel bearing grease,
forcing
the grease through each lubrication fitting

until
it flows from the vent. Vent should be kept
clear
of obstruction or grease
will
back up into the

brakes.
Do not add grease after it flows from the
vent for it may be forced through the wheel key-
way
onto
the outside of the wheel and possibly

onto
the brake linings.
Rear
wheel bearings that do
not have lubrication fittings should be removed
each
12,000
miles
[19.200
km.] and the bearing
cleaned, inspected and repacked. Refer to proce­

dure
in Par. B-56.

Note:
When servicing the Flanged Axle Unit
Bear­

ing Assembly, refer to Section N, Par. N-5 for

proper
lubrication procedures.

B-58.
Propeller Shafts
and
Universal Joints

The
propeller shaft slip joints and universals should
be lubricated with a hand compressor grease gun so as to not damage the bearing seals. The units
should be lubricated with a
good
quality grease.

Refer
to the
Lubrication
Chart
for lubrication fre­
quency and lubricant type and grade. B-59.
