LUBRICATION & SERVICE
s~
ALTERNATOR
The alternator is used in the electrical charging system
and requires no lubrication. The alternator and regula¬
tor are designed for use on only one polarity system.
This tractor utilizes a negative ground system. The fol¬
lowing precautions must be observed when working on
the charging circuit. Failure to observe these precau¬
tions will result in serious damage to the electrical
equipment.
1.
When installing a battery always make absolutely
sure the ground polarity of the battery and the
ground polarity of the alternator are the same. If a
battery is of the wrong polarity, or if the battery is
reversed when installing and connecting it into the
charging system, the battery is directly shorted
through the diodes. This will cause the diodes and
wiring to be engangered by high current flow and
burned out diodes and wiring harness will probably
result.
2.
When connecting a booster battery or auxiliary
starting power as a starting aid, make certain to
follow the same connection procedures as outlined
in the CAUTION steps 1 thru 4 under BATTERY,
Figure 13. Failure to observe this precaution will
result in burned out diodes and wiring harness.
3.
When connecting a battery charger to the batteries,
connect the charger positive lead to the battery
positive terminals and charger negative lead to the
battery negative terminals. Failure to follow this
procedure will result in damage to diodes and
wiring harness. Never attempt to start engine or
turn key switch to the "ON", "GLOW" or "START" po¬
sition while charger is in use.
CAUTION:
Never operate the alternator on
an open circuit. With no electrical load in the
circuit (wires removed or disconnected), the
alternator can build up high voltages which can be ex¬
tremely dangerous to any one who might accidentally
touch the battery terminal on the alternator. Before
making tests or checks, make sure all connections in
the circuit are tight.
4.
Do not short across or ground any terminals of the
alternator or regulator. Grounding or shorting any
of the alternator or regulator terminals can cause
serious electrical malfunctions that may damage
components of the electrical system.
5. Do not attempt to polarize the alternator. This is
not necessary since the voltage developed within
the alternator is of both polarities and the diode
rectifier automatically controls the direction of
current flow. It is important that the battery ground
and the alternator ground be of the same polarity
for diode protection.

INJECTION PUMP LUBRICATION (Figure 18)
Injection pump is not lubricated by the crankcase nor
does it depend on diesel fuel for lubrication. The pump
holds 7 oz. (200 ml) of engine oil for lubrication. The in¬
jection pumpoil should be changed every 200 hours.
DRAIN
Remove drain plug (2) and let oil drain out. Replace
drain plug.
REFILL
To fill injection pump oil sump with oil, remove rack
cover (1) and pour in 7 oz. (200 ml) of oil and replace
rack cover.
NOTE:
If more than 7 oz. (200 ml) of oil is
added it will drain off into crankcase.
