sprocket “B” (3) Measure the rod protrusion. If it is out of specification,
replace the auto tensioner.
Standard value: 12 mm
(.47 in.)
(4) Using a vise with soft jaws push in the auto tensioner rod. If the rod can be easily retracted, replace the auto
tensioner. You should feel a fair amount of resistance when
pushing the rod in.
Caution
1.Clamp the auto tensioner in the vise so it maintains
a level position.
2. If the plug at the bottom of the auto tensioner protrudes, surround it with a plain washer as
illustrated to prevent the plug from being in direct
contact with the vise.

25. 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.
NOTE
If the spacer is installed adversely, the oil seal may be
damaged, resulting in the oil leaks.
23. 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 in
the belt.
. ADJUSTMENT OF TIMING BELT “B” TENSION (1) Temporarily fix the timing belt “B” tensioner such thatthe center of the tensioner pulley is to the left and
above the center of the installation bolt, and temporarily
attach 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.)

21. INSTALLATION OF FLANGE
Install 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 timing belt
could result.
20. 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.
11. INSTALLATION OF AUTO TENSIONER (1) If the auto tensioner rod is in its fully extended position,reset it as follows.
@ Keep the auto tensioner level and, in that position,clamp it in the vise with soft jaws.
If the plug at the bottom of the auto tensioner
protrudes, surround it with a plain washer as illustrated to prevent the plug from being in direct
contact with the vise.
@ Push in the rod little by little with the vise until the set hole
@ in the rod is aligned with that @ in the
cylinder.
@ Insert a wire [1.4 mm (055 in.) in diameter]
into the
set holes.
@ Unclamp the auto tensioner from the vise.

(2) Install the auto tensioner.Caution
Leave the wire installed in the auto tensioner.
13. INSTALLATION OF TENSIONER PULLEY (1) Install the tensioner pulley onto the tensioner arm.
(2) Locate the pinhole in the tensioner pulley shaft to the left of the center bolt. Then, tighten the center bolt
finger-tight.
Caution
Leave the wire installed in the auto tensioner.
12. INSTALLATION OF TIMING BELT (1) Ensure that the timing marks of the camshaft sprocket,the crankshaft sprocket, and the oil pump sprocket are
all aligned.
(2) 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 (.8-1.0 in.), turn the oil pump
sprocket one turn and realign timing marks. Then check
to 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.
NOTE
Step (2) is performed to ensure that the oil pump
sprocket is correctly positioned with reference to the
silent shafts.

(3) Install the timing belt around sprockets as follows.
@ Install the timing belt around the tensioner pulley
and crankshaft sprocket and secure the timing belt
onto the tensioner pulley with your left hand.
@Pulling the belt with your right hand, install it around
the oil pump sprocket.
@Install the belt around the idler pulley.
@ Turn the camshaft sprocket one tooth clockwise to align its timing mark with the cylinder head top sur-
face (see illustration in step
0). Then, pulling the
belt with both hands, install it around the camshaft
sprocket.
@ Gently raise the tensioner pulley as shown by the arrow, so that the belt does not sag, and temporar-
ily tighten the center bolt.
. ADJUSTMENT OF TIMING BELT TENSION (1) After turning the crankshaft
l/4 turn counterclockwise,
turn it clockwise to move the
No.1 cylinder to top dead
center.
(2) Loosen the center bolt, and then, as shown in the illus- tration, 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 assem-
bly.
NOTE
Use a torque wrench that is capable of measurement
within a range of
O-3 Nm (O-2.2
ftlbs.)
(3) Holding the tensioner pulley with the special tool and
torque wrench, tighten the center bolt to specification.
(4) Screw the tool into the engine left support bracket until its end makes contact with the tensioner arm. At that
point, screw the tool in some more and then remove
the set wire attached to the auto tensioner.
(5) Remove the 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 (11)
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 ordinary
method of measurement.
@Screw in the tool until it contacts the tensioner arm.
@From that point of contact, further screw in the tool,
screwing it in until the push rod of the auto ten-
sioner body is caused to move backward and the
tensioner arm contacts the auto tensioner body. Check to be sure that the amount that the tool has
been screwed in (when the push rod moves back-
ward) is the standard value.
Standard value: 2.5-3 turns
