LUB:RICATION
B-26. Speedometer Cable
Remove the speedometer cable from the tube
every 12,000 miles [19.200 km.]. Clean it thoroughly
and coat it with a good quality light graphite
grease.
B-27. Flexible Controls- Choke, Throttle,
Hand Brake
Each 12,000 miles [19.200 km.] or once a year oil
the exterior surfaces of the flexible control conduits
with penetrating oil. This will usually maintain
smooth operation with minimum wear. Should the
hand brake control cable require additional lubri-
cation, remove it from the conduit and coat it
with light graphite grease.
B-28. Clutch Linkage
Lubricate all friction points of the clutch linkage
every 1000 miles [1.600 km.]. Use the same grade
of engine oil as used for the engine. Failure to lubri-
cate these points will result in premature wear; the
links will wear and the holes in the mating parts will
become elongated.
B-29. Body
Often attention is not given to the proper lubrica-
tion of the body hardware. However, when this is
done it should be called to the owner's attention
to avoid soiled clothing. A few drops of oil should
be placed on the tail gate and hood hinges. The
hood catch, hand brake ratchet, cowl ventilator
control, and hood prop should be oiled for easy
operation.
B-30. ADDITIONAL PERIODIC SERVICES
B-31. Brake Master Cylinder
Check the fluid level in the brake master cylinder
every 1000 miles [1.600 km.]. Wipe clean the top
of the filler cap and also the housing area around it.
Replenish the brake fluid to a level Y2" [1 ,3 em.]
below
the top of the fill hole. Use only heavy-duty
brake fluid conforming to specification SAE-70-R3.
Be sure to handle the brake fluid in clean dispensers
and containers that will not introduce even the
slightest amount of other liquids. Replace and
tighten the filler cap.
B-32. Radiator
The exterior of the radiator core should be cleaned
and the radiator inspected for leaks each 1000
miles [1.600 km.] of normal service of the vehicle.
If the vehicle is subjected to considerable off-the-
road operation, this interval should be each 1000
miles or 30 days, whichever interval occurs first.
Refer to Par. H-6.
B-33. Cooling System
The cooling system should be flushed twice a year
and checked for leaks, preferably in the spring and
fall at the time of changing the antifreeze. Refer
to Par. H-1.
B-34. PARTS REQUIRING NO
LUBRICATION
B-35. Water Pump Bearing
1
Clutch Release Bearing
The water pump and clutch release bearings are
16
prelubricated for life when manufactured and
cannot be relubricated.
B-36. Starting Motor Bearings
e Models CJ-3A S/N 30972 and on, CJ-3B, CJ-5.
CJ-6, DJ-3A .
The starting motor bearings are lubricated at
assembly to last between normal rebuild Jlleriods,
For other models, see Par. B-21A.
B-37. Springs
The vehicle springs should not be lubricated. At
assembly theleaves are coated with a long lasting
special lubricant which is designed to last the life,
of the springs.
B-38. Shock Absorbers
Hydraulic direct-action shock absorbers are per-
manently sealed and require no periodic lubrica-
tion service. Also the shock absorber mounting
bushings are not to be lubricated.
B-39. LUBRICATION REQUIREMENTS FOR
FIELD
AND INDUSTRIAL USE
Adequate lubrication becomes increasingly im--
portant when vehicles are used in field or industrial
work and in many types of off-highway operation,
for under these conditions all operating parts of
both the engine and chassis are subjected to un-
usual pressures. At the same time such operation
is usually under abnormal dust and dirt conditionS:
making additional precautions necessary. The im-
portance of correct lubrication for the conditionS:
·of operation cannot be overestimated.
B-40. Engine Oil
Use only a nationally advertised brand of MS type-
oil.
No definite change interval can be recommended
due to the great variety of uses and conditions of
use. It is important, however, that the oil in a new
or rebuilt engine be changed at the first eight or
ten hours of operation and for heavy, dusty work,
every fifty hours thereafter. Do not fail to watch
the condition of the oil closely and should it be-
come contaminated, change it immediately.
B-41. Chassis Lubrication
The period of lubrication depends entirely upon_
the type of work being done. Using the specified
interval of 1000 miles [1.600 km.] recommended
for highway travel as a guide, lubricate at safe-
intervals required for the type of operation being
done. Under the usually extremely dusty conditions.
of field work lubricate these points daily.
Be sure to force enough lubricant into each fitting
to force out the old lubricant which might be
contaminated with grit and which would cause-
rapid wear if allowed to remain.
Do not place lubricant on the various ball and
socket joints or pivot points of the lift linkage as.
dirt will accumulate to form an abrasive mixture.
It is best to simply wipe these parts clean with a_
cloth.
B-42. Oil Filter
Dismantle and clean the filter and replace the-
element at the end of the first 100 hours of service.
