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.

2. Align the timing mark of the intake side camshaft sprocket
to the timing mark on the rocker cover.
NOTE
Even when the sprocket and rocker cover timing marks
are aligned, the intake camshaft will rotate slightly in the
clockwise direction by the force of the valve spring and
will stabilize.
3. Shift and set the crankshaft sprocket timing mark by one
tooth in the counterclockwise direction in the same manner
as the exhaust side camshaft sprocket.
4. Align the oil pump sprocket timing marks.
5. When aligning the oil pump sprocket timing marks, remove
the cylinder block plug, and insert an 8 mm shaft diameter
Phillips driver into the plug hole, and confirm that the
driver shaft can be inserted by 60 mm or more. Do not
remove the Phillips driver until the timing belt has been
attached. If the driver shaft contacts the silent shaft and
only enters 20 to 25 mm, rotate the sprocket once, align
the timing marks again, and then confirm that the Phillips
driver can be inserted by 60 mm or more.
6. Remove the Phillips driver, and set the oil pump sprocket
at a position returned by one tooth in the counterclockwise
direction.

8. Rotate the intake side camshaft sprocket in the
counterclockwise direction. Attach the belt at a position
where the timing mark is deviated by one tooth in the
counterclockwise direction, and then fix with a paper clip.
NOTE
Even if the belt is attached at a position deviated by
one tooth, the intake camshaft will rotate slightly in the
clockwise direction by the force of the valve spring and
will stabilize.
9. Rotate the exhaust side camshaft sprocket in the
clockwise direction, and confirm that the intake side
camshaft sprocket’s timing marks are aligned when the
timing marks are aligned.
10. Attach the timing belt in the order of the idler pulley,
oil pump sprocket and crankshaft sprocket.
NOTE
Attach the timing belt so that it is not deflected.
11. Attach the timing belt to the tensioner pulley.
NOTE
The timing belt can be attached easily to the tensioner
pulley by rotating the intake side camshaft sprocket slightly
in the counterclockwise direction.
12. Rotate the crankshaft sprocket slightly in the clockwise
direction, and remove the timing belt deflection on the
idler pulley side.
13. Confirm that the timing marks on the crankshaft, oil pump
and exhaust camshaft are each deviated by one tooth
in the counterclockwise direction.

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.
