14. Using the special tool, rotate the tensioner pulley in the
counterclockwise direction to tense the timing belt, and
then fix by temporarily tightening the tensioner fixing bolt.
NOTE
Remove the deflection of the timing belt between the
intake side and exhaust side camshafts.
15. Rotate the crankshaft in the clockwise direction, and set
the timing mark at the No. 1 cylinder compression top
dead centre.
16. Set the special tool, and screw it in until the wire inserted
when the auto tensioner was installed slightly moves.
17. Loosen the tensioner pulley fixing bolt.
Caution
The timing belt will loosen at this time due to the
rotation of the intake and exhaust camshafts, so make
sure that the timing belt does not deviate.
18. Rotate the special tool and torque wrench in the
counterclockwise direction to remove the timing belt
deflection.
19. From that state, return to the position where the torque
wrench scale reads 3.5 N•m, and then tighten the fixing
bolt.
20. Remove the special tool installed in step 16.
21. Rotate the crankshaft two rotations in the clockwise
direction, and let stand for approx. 15 minutes.
22. Confirm whether the wire inserted when the auto tensioner
was installed can be pulled out easily. If it can be removed
easily, the belt tension is appropriate, so remove the wire.
If the auto tensioner rod’s protrusion amount is at the
standard value, the tension is appropriate.
Standard value: 3.8 - 4.5 mm
23. If the wire cannot be pulled out easily, repeat steps 16
to 21, and tense the belt to the appropriate tension.
Caution
When the crankshaft bolt has been rotated in the
counterclockwise direction, always check the crank-
shaft bolt’s tightening torque. If loosen, re-tighten.

INSPECTION
1. TIMING BELT
Inspect each section of the belt in detail, and if any of
the following type of damage is found, replace the belt
with a new part.
(1) Hardening of backface rubber.
The backface is glossy, marks are not made even
when a fingernail is run cross it, and there is no
elasticity.
(2) Cracking of backface rubber.
(3) Cracking of canvas.
(4) Cracking at root.
(5) Cracking on side of belt.
(6) Abnormal wear on side of belt.
NOTE
The state is normal if the cutting surface is neat as
if cut with a sharp knife.
(7) Abnormal wear of teeth.
First stages: Canvas is worn (canvas fibres are raised,
rubber is removed and whitish, and canvas seams
are unclear).
Latter stages: Canvas is worn off, and rubber is
exposed (face width is narrow).
(8) Teeth are missing.
2. AUTO TENSIONER
(1) Check for oil leaks. If any leaks are found, replace.
(2) Check whether the rod end is worn or damaged,
and replace if necessary.
(3) Measure the rod protrusion length. If not at the
standard value, replace the auto tensioner.
Standard value: 12 mm

3. Following the tightening order, tighten at 78±2N•m.
4. Completely loosen the bolts.
5. Next, following the tightening order, tighten the loosened
bolts at the torque 20±2N•m again.
6. Make paint marks on the cylinder head bolt’s head and
cylinder head.

by 90_.
8. Tighten by another 90_, and confirm that the paint mark
made on the cylinder head bolt’s head and the paint
mark on the cylinder head are positioned on the same
line.
Caution
(1) If the tightening angle is less than 90_, the
connection performance may not be attained, so
take special care to the tightening angle when
tightening.

value, completely loosen the bolt and start again
from step 1.
INSPECTION
1. CYLINDER HEAD
(1) Before cleaning the cylinder head, check it for water
leaks, gas leaks, damage or cracks.
(2) Completely remove the oil, water deposits, sealant
and carbon, etc. After cleaning the oil path, blow
air and confirm that there is not clogging.
(3) Using a straight edge and thickness gauge, inspect
the flatness of the bottom of the cylinder head for
strain.
If the strain exceeds the limit value, grind the end
and correct the flatness.
Standard value for lower surface strain: 0.05 mm
Limit value for lower surface strain: 0.2 mm
Grinding limit value: 0.2 mm
Cylinder head height (standard value for new part):
131.9 - 132.1 mm
Caution
The grinding limit is within 0.2 mm together with
the combined cylinder block.

ENGINE LUBRICATION -General Information12-2
GENERAL INFORMATION
The lubrication method is a fully force-fed, full-flow
filtration type. The oil pump is a gear type which
is driven by the crankshaft via the timing belt.
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 contains potentiallyharmful contaminants 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:
DAvoid prolonged and repeated contact with oils,
particularly used engine oils.
DWear protective clothing, including impervious
gloves where practicable.
DAvoid contaminating clothes, particularly
underpants, with oil.
DDo not put oily rags in pockets, the use of
overalls without pockets will avoid this.
DDo not wear heavily soiled clothing and
oil - impregnated foot - wear. Overalls must be
cleaned regularly and kept separate from
personal clothing.DWhere 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.
DObtain First Aid treatment immediately for open
cuts and wounds.
DWash regularly with soap and water to ensure
all oil is removed, especially before meals (skin
cleansers and nail brushes will help). After
cleaning, the application of preparations
containing lanolin to replace the natural skin
oils is advised.
DDo not use petrol, kerosine, diesel fuel, gas
oil, thinners or solvents for cleaning skin.
DUse barrier creams, applying them before each
work period, to help the removal of oil from
the skin after work.
DIf skin disorders develop, obtain medical advice
without delay.
