EA CRANKSHAFT SPROCKET B INSTALLATION
Clean the crankshaft sprocket B installation surface before
degreasing the crankshaft sprocket B.
NOTE
Always degrease the surface to prevent a drop in the frictional
coefficient at the pressing section caused by the adherence
of oil.
"
FA SPACER INSTALLATION
1. Apply a slight amount of oil on the outer periphery of
the spacer (oil seal contact section).
2. Insert the spacer from the chamfered side as shown in
the illustration.
Caution
Reversed insertion of the spacer can cause damage
to the oil seal lip.
"
GACOUNTER BALANCE SHAFT SPROCKET
INSTALLATION
1. Fix the counter balance shaft sprocket with the special
tool.
2. Tighten the counter balance shaft sprocket installation
bolt at the specified torque 46 ± 3 N•m.
"
HA TIMING BELT B INSTALLATION
1. Align the crankshaft sprocket B and counter balance shaft
sprocket timing marks with the timing mark on the oil
pump case.
2. Attach the timing belt B to the crankshaft sprocket B
and counter balance shaft sprocket.
Do not loosen the belt tension too much at this time.

3. Confirm that the tensioner B centre and bolt centre are
positioned as shown in the illustration.
4. Apply tension on the timing belt by lifting tensioner B
in the direction of the arrow with a finger, and tension
the tension side until it is “tight”. Fix tensioner B in this
state by tightening the bolt.
NOTE
Make sure that the tensioner B shaft does not rotate
when tightening the bolt. If the shaft rotates, the timing
belt becomes too tense.
5. Connect the special tool (MB991704) to MUT-II and the
battery.
6. Connect the special tool (MB991668) to MUT-II.
7. Rotate the crankshaft clockwise two turns, and align each
timing mark.
8. Select “Belt Tension Measurement” from the MUT-II menu
screen.
9. Separate the special tool (MB991668) 10 to 20 mm from
the centre back between the sprockets (shown with an
arrow), and hold so that it is vertical (inclination within
±15_) in respect to the belt.
10. Lightly tap the section shown with an arrow with fingers,
and measure the belt vibration frequency. If the results
are deviated from the standard value, loosen the bolt,
tension the belt again, and then measure the vibration
frequency again. Repeat this step until the standard value
is attained. Tighten the bolt when the standard value
is attained.

Caution
(1) Measure when the belt’s surface temperature is
close to room temperature.
(2) Make sure that water or oil, etc., do not get on
the mike.
(3) If strong winds contact the mike or if noise is
generated in the area while measuring, a value
that differs from the actual value may be indicated.
(4) If the measurement is carried out with the mike
contacted against the belt, a value that differs
from the actual value may be indicated.
(5) Do not measure while the engine is running.
11. Disconnect MUT-II.
12. When measuring with the deflection amount, press the
centre of the tensed side of timing belt B with your index
finger in the arrow direction, and confirm that the deflection
is between 5 and 7 mm.

IA CRANKSHAFT BOLT/CRANKSHAFT
SPROCKET/CRANKSHAFT SENSING BLADE
INSTALLATION
1. Clean and degrease the crankshaft sprocket, crankshaft
sprocket installation surface of crankshaft and crankshaft
sensing blade, and then install the crankshaft sprocket
and crankshaft sensing blade.
2. Clean the crankshaft bolt hole section.
3. Apply the minimum required amount of engine oil on the
crankshaft bolt section and upper surface of the washer.
4. Fix the flywheel with the special tool.
5. Tighten the crankshaft bolt at the specified torque 162
± 5 N•m.

JA OIL PUMP SPROCKET INSTALLATION
1. Stop the rotation of the counter balance shaft in the same
manner as for removal.
2. Install the oil pump sprocket.
3. Apply the minimum required amount of engine oil on the
flange nut seat surface.
4. Tighten the flange nut at the specified torque 54 ± 5
N•m.
"
KA AUTO TENSIONER INSTALLATION
1. If the auto tensioner rod is in the extended state, set
it with the following steps.
(1) Set the rod of the auto tensioner into a vice so that
it is straight and not inclined.
(2) Press in the rod gradually with the vice, and align
the rod’s set hole A with the cylinder’s set hole B.
(3) Insert a wire (diameter 1.4 mm) into the set holes.
(4) Remove the auto tensioner from the vice.
2. Install the auto tensioner.
Do not remove the wire until the timing belt has been
installed.
"
LA TENSIONER PULLEY INSTALLATION
Set the tensioner pulley as shown in the illustration.
"
MATIMING BELT INSTALLATION
1. Set the timing mark on the exhaust side camshaft sprocket
so that it is deviated by one tooth in the counterclockwise
direction from the timing mark on the rocker cover.
NOTE
Even if the sprocket and rocker cover timing marks are
aligned, the exhaust camshaft will return in the
counterclockwise direction by the force of the valve spring
and will stabilize at a position deviated by one tooth.
