Tractor Lubrication - International Harvester Company TD-14A Operator's Manual

PREVENTIVE MAINTENANCE
TRACTOR LUBRICATION
Thorough lubrication service performed
at definite intervals and according to an estab-
lished routine will aid greatly in prolonging
the life of the tractor and in reducing oper-
ating expense. In the "LUBRICATION GUIDE" o n
the fo 11 ow ing pages the recommended intervals
between lubrication periods are approximate,
being based on average operating conditions.
The type of work being done, load, ground
and weather conditions are all factors to con-
sider in frequency of lubrication. The life
and performance of a machine depend on the
care that it is given. Proper lubrication is
probably the most important maintenance
service for your tractor.
Oil Pump Screen
The gear type oil pump in the crankcase
oil pan has a screen attached to the oil intake
to stop large dirt particles from entering the
lubrication system. This screen should be
cleaned whenever the oil pan is removed. The
oil intake floats on top of the oil in the oil pan
and always draws the oil from the surface,
thus preventing water or sediment from mix-
ing with the oil.
Oil Filler Strainer Screen
At regular intervals, remove the oil filler
strainer screen from the oil filler and clean
the screen.
Crankcase Breather
The crankcase breather, located in the
push rod chamber on the right side of the
crankcase, has a double metal crimp element.
Clean the element after every 240 hours of
operation, or more when operating under un-
usual dust or dirt conditions. If necessary,
replace with a new breather element.
Oil Filters
The engine is equipped with full flow
type oil filters designed
to
remove all harm-
ful foreign particles from the oil before it
is distributed to the engine. To obtain full
benefit from the filters the elements should
be repla~ed with new ones every 480 hours.
The oil filters keep the oil free from
harmful contamination for 480 hours of oper-
ation under normal operating conditions.
However, it may be necessary to replace the
filter element after shorter operating periods
under severe operating conditions such as
extreme dust conditions, low engine tempera-
ture, intermittent load operating with long
stand-by periods, excessively heavy loads
where high oil temperatures are the rule, or
when diesel fuel with a high sulphur content
is used.
Cleaning the old element is not satisfactory.
For the recommended oil to use for the
prevailing temperature refer to "LUBR I CAT ION
GUIDE" o n pages 2ij and 25.
Oil Pressure Indicator
The oil pressure indicator shows the
pressure of the oil circulating through the
engine. Under all operating conditions the
oil pressure of the engine should hold the in-
dicator in the white section. If the indicator
does not register, stop the engine at once and
inspect the oil system to find the cause of
failure.
If unable to find the cause, consult
your International Industrial Power distrib-
utor or dealer before ope r ating the engine.
Always look at the oil pressure indicator
immediately after starting the engine.
Oil Level Gauge
Do not operate the engine for any length
of time with the crankcase oil below the wLOW·
mark on the bayonet oil level gauge.
To check the oil level with the bayonet
gauge, unscrew the wing nut, remove the gauge
wipe it clean and insert it in the crankcase
until the wing nut rests on top of the gauge
sleeve threads. Do not screw the nut onto the
sleeve. Remove the gauge again and read the
oil level.
NOTE: The gauge has readings on both
sides and can be used when the engine is run-
ning or when it is stopped. Be sure to use
the correct side.
If the engine han just been
stopped, allow five to ten minutes for the oil
to drain down into the oil pan before taking
the reading; otherwise, the reading might not
show the true amount of oil in the crankcase
and more aU than necessary might be added.
