6EN I1231. INSTALLATION OF
FLANGEInstall the flange in correct direction as shown.
Caution
Pay special attention to the direction of the flange. If it
is installed in the wrong direction, a broken timiiig ‘beltcould result.
30. INSTALLATION OF CRANKSHAFT SPROCKET
Install the crankshaft sprocket in the correct direction as
shown.Caution
Pay special attention to the direction of the flange. If it
is installed in the wrong direction, a broken timing belt
could result.
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
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.

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
