ENGINE OVERHAUL -Timing Belt11B-19
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.

"KAAUTO 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.
"LATENSIONER 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.

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.

4. If there is no identification, measure the oil clearance
and select.
"FACONNECTING ROD CAP INSTALLATION
1. Align the marks made during disassembly, and install
the bearing cap onto the connecting rod. When using
a new connecting rod that has no match marks, assemble
so that the bearing rotation-preventing notch comes to
the same side as shown in the illustration.
2. The plasticity range tightening method is adopted for the
connecting rod bolt and nut, so elongate and inspect
the bolt before reusing it.
Inspect that the bolt is elongated to the extent that the
nut can be screwed onto the last thread when screwed
by hand. If the nut cannot be screwed on smoothly to
the end, the bolt threads are elongated and the bolt must
be replaced.
3. Apply engine oil on the nut’s threads and seat surface
before installing the nut.
4. After installing each nut onto the bolt with fingers,
alternately tighten the nuts to assemble the cap correctly.
5. Tighten the nut at a 20 N•m torque.
6. Make a paint mark on the head of the nut.
7. Using the position of the mark painted on the nut as
reference, make paint marks on the bolt at the 90_to
94_positions in the nut tightening direction.
8. Tighten the nut between 90_and 94_, and confirm that
the paint marks on the nut and bolt match.
Caution
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.
If the tightening angle is larger than 94_, completely
loosen the nut and start again from step 1.
