GENERAL INFORMATION
M1121000100357
The lubrication method is a fully force-fed, full-flow fil-
tration type. The engine oil pump is a trochoid type
which is driven by the crankshaft <4G1>.The engine
oil pump is a gear type which is driven by the crank
-
shaft via the balancer timing belt <4G6>.
ENGINE OILS
Health Warning
Prolonged and repeated contact with mineral oil will
result in the removal of natural fats from the skin,
leading to dryness, irritation and dermatitis. In addi
-
tion, used engine oil contains potentially harmful con-
taminants which may cause skin cancer. Adequate
means of skin protection and washing facilities must
be provided.
Recommended Precautions
The most effective precaution is to adapt working
practices which prevent, as far as practicable, the
risk of skin contact with mineral oils, for example by
using enclosed systems for handling used engine oil
and by degreasing components, where practicable,
before handling them. Other precautions:
•Avoid prolonged and repeated contact with oils,
particularly used engine oils.
•Wear protective clothing, including impervious
gloves where practicable.
•Avoid contaminating clothes, particularly under-
pants, with oil.
•Do not put oily rags in pockets, the use of overalls
without pockets will avoid this.
•Do not wear heavily soiled clothing and
oil-impregnated foot-wear. Overalls must be
cleaned regularly and kept separate from per
-
sonal clothing.
•Where there is a risk of eye contact, eye protec-
tion should be worn, for example, chemical gog-
gles or face shields; in addition an eye wash
facility should be provided.
•Obtain first aid treatment immediately for open
cuts and wounds.
•Wash regularly with soap and water to ensure all
oil is removed, especially before meals (skin
cleansers and nail brushes will help). After clean
-
ing, the application of preparations containing
lanolin to replace the natur al skin oils is advised.
•Do not use petrol, kerosine, diesel fuel, gas oil,
thinners or solvents for cleaning skin.
•Use barrier creams, applying them before each
work period, to help the removal of oil from the
skin after work.
•If skin disorders develop, obtain medical advice
without delay.

GENERAL INFORMATION
ENGINE COOLING14-2
GENERAL INFORMATION
M1141000100371
The cooling system is designed to keep every part of
the engine at appropriate temperature in whatever
condition the engine may be operated. The cooling
method is of the water-cooled, pressure forced circu
-
lation type in which the water pump pressurizes cool-
ant and circulates it throughout the engine. If the
coolant temperature exceeds the prescribed temper
-
ature, the thermostat opens to circulate the coolant
through the radiator as well so that the heat
absorbed by the coolant may be radiated into the air.
The water pump is of the centrifugal type and is
driven by the alternator drive belt from the crank
-
shaft. The radiator is the corrugated fin, down flow
type.

The charging system uses the alternator output to
keep the battery charged at a constant level under
various electrical loads.

The average outpu t volt a ge flu c tua t es slightly with

When the ign i tion switch is t u rned on, current flows in
the field coil and initial e

When the st ator coil beg ins to gen erate p o wer af ter
