ORDisconnect air conditioner compressor connector and
remove it with hoses from the compressor bracket.
NOTEThe removed air conditioner compressor should be fas-
tened (by using rope, etc.) in a position that will not
interfere with the removal/installation of the engine assem-
bly.
38. DISCONNECTION OF ENGINE MOUNT BRACKET
Before removing the engine mount bracket installation bolt,use a chain block or similar arrangement to suspend the
engine assembly (to the extent that there is no looseness
of the chain).
40. DISCONNECTION OF ENGINE ASSEMBLY
After checking that the cables, hoses, harness connectors,etc. are all removed, slowly raise the chain block to lift the
engine assembly upward out of the engine compartment.

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.

(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.

h(1) Visually check the camshaft journal surfaces and replace if
_damage or seizure is evident.
If the journal is seized, check the cylinder head for possibledamage. Check also for clogged oil holes in the cylinder
head.
(2) Check cams for excessive wear and damage and replace if
defects are evident. Measure the cam height and replace ifthe limit is not reached.

(2) Check the roller for smooth rotation. Replace if it binds or
there is an excessive play.
(3) Check the valve contact surface for possible damage or
seizure and replace as necessary.
SERVICE POINTS OF REASSEMBLYNOSLGAB10. INSTALLATION OF CAMSHAFT
(1) Apply engine oil to journals and cams of the camshafts.
(2) Install the camshafts on the cylinder head.
Use care not to confuse the intake camshaft with the
exhaust one. The intake camshaft has a slit on its rear
end for driving the crank angle sensor.
(3) Make also sure that the dowel pins on the camshaft
sprocket end are located on the top.

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.
