ENGINE OVERHAUL -Timing Belt11B-20
"JAOIL 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.
"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.

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.
7. Attach the timing belt to the exhaust side camshaft
sprocket, and fix with a paper clip at the position shown
in the illustration.

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.
