9-98ENGINE <2.0L DOHC Engine> - Timing Belt22. REMOVAL OF TIMING BELT
Make a mark on the back of the timing belt indicating the
direction of rotation so it may be reassembled in the same
~direction if it is to be reused.
Caution
Water or oil on the belt shorten its life drastically, so
the removed timing belt, sprocket, and tensioner must
be free from oil and water. These parts should not be
washed. Replace parts if seriously contaminated.
If there is oil or water on each part check the front caseoil seals, camshaft oil seal and water pump for leaks.
26. REMOVAL OF CAMSHAFT SPROCKETS
(1) Using a wrench, hold the camshaft at its hexagon
(between the No.2 and No.3 journals) and remove the
camshaft sprocket bolt.
Caution
Locking the camshaft sprocket with a tool damagesthe sprocket.
(2) Remove the camshaft sprockets.
127. REMOVAL OF OIL PUMP SPROCKET
(1) Remove the plug on the side of the cylinder block.
(2) Insert a Phillips screwdriver [shank diameter 8 mm
(.31in.)] to block the left silent shaft.
(3) Remove the oil pump sprocket nut.
(4) Remove the oil pump sprocket.
33. REMOVAL OF TIMING BELT “B”
Make a mark on the back of the timing belt indicating the
direction of rotation so it may be reassembled in the same
direction if it is to be reused.
Caution
Water or oil on the belt shorten its life drastically, so
++the removed timing belt, sprocket, and tensioner must
be free from oil and water. These parts should not be
washed. Replace parts if seriously contaminated.
If there is oil or water on each part check the front caseoil seals, camshaft oil seal and water pump for leaks.

27. INSTALLATION OF OIL PUMP SPROCKET
(1) Insert a Phillips screwdriver [shank diameter 8 mm
(.31in.) shaft] through the plug hole on the left side of
cylinder block to block the left silent shaft.
(2) Install the oil pump sprocket.
(3) Tighten the nut to the specified torque.
26. INSTALLATION OF CAMSHAFT SPROCKETS

mar22. INSTALLATION OF TIMING BELT
(1) Turn the two sprockets so that their dowel
pind arti
located on top. Then, align the timing marks facing each
-
*other with the top surface of the cylinder head. When,
you let go of the exhaust camshaft sprocket, it will
rotate one tooth in the counterclockwise direction. This
should be taken into account when installing the timing
belt on the sprockets.
NOTE
The same camshaft sprocket is used for the intake andexhaust camshafts and is provided with two timing
marks. When the sprocket is mounted on the exhaust
camshaft, use the timing mark on the right with the
*dowel pin hole on top. For the intake camshaft
-sprocket, use the one on the left with the dowel pin
hole on top.
(2) Align the crankshaft sprocket timing mark.
(3) Align the oil pump sprocket timing mark.
(4) Remove the plug on the cylinder block and insert a
Phillips screwdriver [shank diameter 8 mm
(.31 in.)]
through the hole.
If it can be inserted as deep as 60 mm (2.4 in.) or more,the timing marks are correctly aligned. If the inserted
depth is only
20-25 mm (.8-l .O in.), turn the oil pump
sprocket one turn and realign timing marks. Then checkto ensure that the screwdriver can be inserted 60 mm
(2.4 in.) or more. Keep the screwdriver inserted until theinstallation of the timing belt is finished.,+
.
NOTEStep (4) is performed to ensure that the oil pump
sprocket is correctly positioned with reference to the
silent shafts.

P(5) Thread the timing belt over the intake side camshaft
sprocket and fix it an indicated position by a clip.
(6) Thread the timing belt over the exhaust side sprocket,
aligning the timing marks with the cylinder head top
surface using two wrenches.
(7) Fix the belt at indicated position by a clip.
(8) Thread the timing belt over the idler pulley, the oil pumpsprocket, the crankshaft sprocket and the tension
pulley in the order shown.
(9) Remove the two clips.
(1O)Lift up the tensioner pulley in the direction of arrow andtighten the center bolt.
(11)Check to see that all timing marks are lined up.
(12)Remove the screwdriver inserted in step (4) and fit the
plug.
(13)Give the crankshaft a quarter counterclockwise turn.
Then, turn it clockwise until the timing marks are lined
up again.

9-106ENGINE <2.0L DOHC Engine> - Timing Belt. ADJUSTMENT OF TIMING BELT TENSION
(1) After turning the crankshaft
l/4 turn counterclockwise,.5;;turn it clockwise to move the No. 1 cylinder to top dead
center.(2) Loosen the center bolt, and then, as shown in the
illustration, attach the special tool and a torque wrench
and apply a torque of 2.6-2.8 Nm
(1.88-2.03 ft.lbs.).If the body interferes with the special tool and the
torque wrench, use a jack to slightly raise the engine
assembly.
NOTEUse a torque wrench that is capable of measurement
within a range of
O-3 Nm (O-2.2 ft.lbs.).(3) Holding the tensioner pulley with the special tool and
torque wrench, tighten the center bolt to specification.
(4) Screw the special tool into the engine left support
bracket until its end makes contact with the tensioner
arm. At that point, screw the special tool in some more
and then remove the set wire attached to the auto
tensioner.(5) Remove the special tool.
(6) Rotate the crankshaft two complete turns clockwise
and leave it as is for about 15 minutes. Then, measure
the auto tensioner protrusion “A” (distance between
the tensioner arm and auto tensioner body) to ensure,.+
that it is up to specification.
Standard value:
3.8-4.5 mm (.15-.18 in.)
If it is out of specification, repeat steps (6) through (1)
until the specified value is obtained.
(7) If the clearance between the tensioner arm and the
auto tensioner body cannot be measured (when the
engine is being mounted, etc.), the following proce-
dures can be used to substitute for the ordinan/ methodof measurement.
@ Screw in the special tool until it contacts the
tensioner arm.
@ From that point of contact, further screw in the
special tool, screwing it in until the push rod of the
auto tensioner body is caused to move backward
and the tensioner arm contacts the auto tensioner
body.Check to be sure that the amount that the special
tool has been screwed in (when the push rod
moves backward) is the standard value.
Standard value: 2.5-3 turns

Tighten to specification in the final sequence.
(3) Check to be sure that the rocker arm is correctly placedon the lash adjuster and valve stem end.
5. INSTALLATION OF CAMSHAFT OIL SEAL
(1) Install the special tool, Guide, on the camshaft.
(2) Apply oil to the oil seal and insert the seal along the
Guide until it contacts the cylinder head.
(3) Using the special tool, Installer, press-fit the oil seal intothe cylinder head.
2. INSTALLATION OF CAMSHAFT SPROCKET
Using a wrench hold the camshaft at its hexagon (betweenthe
No.2 and No.3 journals) and tighten the bolt to
specification.Caution
Locking the camshaft sprocket with a tool damages the
sprocket.1. INSTALLATION OF CRANK ANGLE SENSOR
(1) Locate the dowel pin on the sprocket side of the intake
camshaft at top.
(2) Align the punch mark on the crank angle sensor housingwith the notch in plate.
NOTE
The crank angle sensor can be installed even when thepunch mark is positioned opposite the notch; however,
the position results in incorrect fuel injection and
ignition timings.
(3) Install the crank angle sensor on the cylinder head.
