INSTALLATION
(1) Install the bearing caps so that points to the
timing belt side.
(2) Before installing the bearing cap bolts, check that the,
shank length of each bolt “meets the limit., If, th e limit’
is exceeded, replace the bolt.
Limit (A): Max. 71.1 mm (2.80 in.)
(3) Apply engine oil to the threaded portion
sur-
face of the bolt.
(4) Tighten the bolts to 25 Nm
in ‘the’
tightening sequence.
(5) Make a paint mark on the head of each bolt.
(6) Make a paint mark on the bearing cap at the pos ition
to from the paint mark made on the bolt in
the direction of tightening the bolt.
(7) According to the specified tightening sequence, give a
to turn to each bolt and make sure that the
paint mark onthe bolt and that on the cap are in alignment.
Caution
If the bolt is turned less than proper fastening
performance may not be expected.When
tightening the bolt, therefore, be careful to
a sufficient turn to it.
2. If the bolt is overtightened (exceeding
loosen the bolt completely and then retighten it by
repeating the tightening procedure from step (1).
(8)After installing the bearing caps, make sure that t he crank-
shaft turns smoothly and the end play is correct. I f the
end play exceeds the limit, replacer crankshaft bear-
ings.

ENGINE LUBRICATION General Information/Lubricants
G E N E R A L I N F O R M A T I O N
The lubrication method is a fully force-fed, full-f low
filtration type.
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 addition, used engine oil
potentially
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:
lAvoid prolonged and repeated contact with oils,
particularly used engine oils.
l Wear protective clothing, including impervious
gloves where practicable.
l Avoid contaminating clothes, particularly
underpants, with oil.
l Do not put oily rags in packets, the use of
overalls without pockets will avoid this.
l Do not wear heavily soiled clothing and
oil-impregnated foot-wear. Overalls must be
cleaned regularly and kept separate from
personal clothing.
LUBRICANTS
harmful contaminants which may cause skin cancer.
Adequate means of skin protection and washing
facilities must
provided.
Where there is a risk of eye contact, eye protection should be worn, for example,
chemical goggles 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
cleansers and nail brushes will help). After
cleaning, the application of
containing lanolin to replace the natural
oil is advised.. .
Do not use gasoline, kerosine, diesel fuel,
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.
