-35. INSTALLATION OF SPACER
(1) Apply a thin coat of engine oil to the outer circumfer-
ence of the spacer.
(2) Install the spacer with the chamfered end facing the oil
seal.
NOTEIf the spacer is installed adversely, the oil seal may be
damaged, resulting in the oil leaks.
33. INSTALLATION OF TIMING BELT “B”
(1) Ensure that crankshaft sprocket “B” timing mark and
the silent shaft sprocket timing mark are aligned.
(2) Fit timing belt “B” over crankshaft sprocket “B” and
the silent shaft sprocket. Ensure that there is no slack inthe belt.
.ADJUSTMENT OF TIMING BELT “B” TENSION
(1) Temporarily fix the timing belt “B” tensioner such that
the center of the tensioner pulley is to the left and
above the center of the installation bolt, and temporarilyattach the tensioner pulley so that the flange is toward
the front of the engine.
(2) Holding the timing belt “B” tensioner up with your
finger in the direction of the arrow, place pressure on
the timing belt so that the tension side of the belt is
taut. Now tighten the bolt to fix the tensioner.
Caution
When tightening the bolt, ensure that the tensioner
pulley shaft does not rotate with the bolt. Allowing
it to rotate with the bolt can cause excessive
tension on the belt.
(3) To ensure that the tension is correct, depress the belt
(point A) with a finger. If not, adjust.
Standard value: 5-7 mm
(.20-.28 in.)

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
