PREVENTIVE MAUNTENANCE
CHANGES IN TEMPERATURE
It is not necessary to change crankcase
oil during operation when the atmospheric
temperature rises or falls into another tem-
perature range as specified in the "LUBRI-
CATION GUIDE" o n the following pages. For
example: SAE-20 can be used instead of
SAE-IOW in temperatures below 32° F. if
no starting trouble is experienced; or the
SAE-IOW oil that is specified for use in tem-
peratures 32° to 10° F. can be used in tem-
peratures as high as 40° F.; or the SAE-IOW
oil that is recommended for use in temper-
atures below 10° F. can be used in tempera-
tures as high as 32° F. and even up to 40° F.,
except when operating under continuously
heavy loads.
THINNING THE CRANKCASE OIL
When using lighter grades of lubricating
oils, there may be a tendency for the oil in the
crankcase to gradually become thicker; in
this case it is desirable in cold weather to add
one quart of kerosene to the crankcase be-
tween specified oi l changes to maintain easy
cranking.
L UBRICATION WHEN SHIPPED
The lubricant in the crankcase, air
cleaner, and injection pumps in diesel engines,
when shipped from the factory, is for ship-
away purposes and is not suitable for use in
regulator service. 'I'he original oil should
immediately be drained from the crankcase,
air cleaner, and injection pump and should be
replaced with the required amount of fresh oil
having the physical properties and proper
viscosity for the prevailing air temperatures
and type of service.
CHANGE AFTER EVERY 240 HOURS
Change oil in the crankcase after every
240 hours of operation, or more often under
abnormal operating conditions. Drain the
crankcase while the oil is warm so it will
drain freely and completely. A

Mter changing
oi.I,
the engine should not
be operated at high speed or under load until
the new oil has had ample time to reach all
bearings.
After changing to a lighter grade of oil the
engine should be operated at least
5
to 10
minutes without load so that the lighter oil is
worked into the bearings and onto the cylinder
walls.
Chassis Lubricant when Shippedfrom
Factory
All crawler tractors shipped from the
factory between April l s
t
and October 1st are
filled with SAE-90 in the transmission and
sprocket drives and SAE-140 in the track
rollers and track idlers.
All crawler tractors shipped from the
factory between October l s
t
and April 1st are
filled with SAE-80 in the transmission and
sprocket drives, and SAE-90 in the track
rollers and track idlers.
The oil in the transmission and sprocket
drive housings should be changed at least once
a year; however, do not operate the tractor
more than 960 hours without changing.
Whenever the oil in the transmission and
sprocket drive housings is changed, wash out
the housings with kerosene before refilling
with oil. First drain the old oil from these
housings; then fill the housings to the proper
level with kerosene. Operate the tractor in
low gear for several minutes. Remove the
drain plugs from these housings and allow time
for complete drainage of the kerosene. Refill
with universal gear lubricant.
In the track rollers and idlers use univer-
sal gear lubricant as .specified in the "LUBRI-
CA
TI
ONGU IDE" on the fo
11
ow ing pages, depend-
ing upon the prevailing air temperature.
Draining Clutch Compartments
When operating the tractor in water, under
very wet cpnditions or under extremely dusty
conditions water or dust may enter the en-
gine clutch or steering clutch compartments
through the holes in the drain plugs. To avoid
this replace the drain plugs with solid plugs.
Remove the plugs after every 60 hours of
operation to allow any oil accumulation to
drain out.
Tractors Exported
When tractors are packed for export all
oil is drained from the crankcase, air cleaner
and fuel injection pump. Before starting to
operate the tractor, give it complete lubri-
cation service. Refer to the "LUBRICATION
GUIDE" o n the following pages.
