DRIVE BELTSPFP:02117
Checking Drive BeltsEBS00KN7
WARNING:
Be sure to perform this step when the engine is stopped.

Make sure that the indicator (notch on fixed side) of drive belt auto-tensioner is within the possible use
range (between three line notches on moving side).
NOTE:

Check the drive belt auto-tensioner indication when the engine is cold.

When new drive belt is installed, the indicator (notch on fixed side) should be within the range “a” in the
figure.

Visually check entire drive belt for wear, damage or cracks.

If the indicator (notch on fixed side) is out of the possible use range or belt is damaged, replace drive belt.
Tension AdjustmentEBS00KN8
Belt tensioning is not necessary, as it is automatically adjusted by drive belt auto-tensioner.
Removal and InstallationEBS00KN9
REMOVAL
1. Remove splash guard on RH undercover.
2. Hold the hexagonal part in center of drive belt auto-tensioner
pulley with a box wrench securely. Then move the wrench han-
dle in the direction of arrow (loosening direction of tensioner).
CAUTION:

Avoid placing hand in a location where pinching may
occur if the holding tool accidentally comes off.

Do not loosen the hexagonal part in center of drive belt
auto-tensioner pulley (Do not turn it counterclockwise). If
turned counterclockwise, the complete drive belt auto-
tensioner must be replaced as a unit, including the pul-
ley.
3. Insert a rod approximately 6 mm (0.24 in) in diameter such as
short-length screwdriver into the hole of the retaining boss to fix drive belt auto-tensioner pulley.
4. Loosen drive belt from water pump pulley in sequence, and remove it.

INSTALLATION
1. Hold the hexagonal part in center of drive belt auto-tensioner
pulley with a box wrench securely. Then move the wrench han-
dle in the direction of arrow (loosening direction of tensioner).
CAUTION:

Avoid placing hand in a location where pinching may
occur if the holding tool accidentally comes off.

Do not loosen the hexagonal part in center of drive belt
auto-tensioner pulley (Do not turn it counterclockwise). If
turned counterclockwise, the complete drive belt auto-
tensioner must be replaced as a unit, including the pul-
ley.
2. Insert a rod approximately 6 mm (0.24 in) in diameter such as
short-length screwdriver into the hole of retaining boss to fix drive belt auto-tensioner pulley.
3. Hook drive belt onto all pulleys except for water pump, and then onto water pump pulley finally.
CAUTION:

Confirm drive belt is completely set to pulleys.

Check for engine oil, working fluid and engine coolant are not adhered to drive belt and each
pulley groove.
4. Release drive belt auto-tensioner, and apply tension to drive belt.
5. Turn crankshaft pulley clockwise several times to equalize tension between each pulley.
6. Confirm tension of drive belt at indicator (notch on fixed side) is within the possible use range. Refer to
EM-13, "
Checking Drive Belts" .

CAUTION:
Do not loosen the hexagonal part in center of drive belt auto-tensioner pulley (Do not turn it counter-
clockwise). If turned counterclockwise, the complete drive belt auto-tensioner must be replaced as a
unit, including the pulley.
INSTALLATION
Note the following, and install in the reverse order of removal.

When installing drive belt auto-tensioner, be careful not to interfere with water pump pulley.
CAUTION:

If there is damage greater than peeled paint, replace drive belt auto-tensioner.

Do not swap the pulley between new and old drive belt auto-tensioner.

CAUTION:
Be careful not to damage mounting surface.
17. If front oil seal needs to be replaced, lift it with a suitable tool, and remove it.
CAUTION:
Be careful not to damage front cover.
18. Remove timing chain and camshaft sprockets with the following procedure:
a. Push in chain tensioner plunger. Insert a stopper pin into hole on
chain tensioner body to secure chain tensioner plunger and
remove chain tensioner.
NOTE:
Use approx. 0.5 mm (0.02 in) dia. hard metal pin as a stopper
pin.
b. Secure hexagonal part of camshaft with a wrench. Loosen cam-
shaft sprocket mounting bolts and remove timing chain and
camshaft sprockets.
CAUTION:
Do not rotate crankshaft or camshaft while timing chain is
removed. It causes interference between valve and piston.
19. Remove timing chain slack guide, timing chain tension guide and oil pump drive spacer.
20. Remove balancer unit timing chain tensioner with the following procedure:

NOTE:
Use TORX socket (size E14).
INSPECTION AFTER REMOVAL
Timing Chain
Check timing chain for cracks and any excessive wear at the roller
links of timing chain. Replace timing chain if necessary.
Balancer Unit Mounting Bolt Outer Diameter

Measure the outer diameters (“d1”, “d2”) at two positions as
shown in the figure.

If reduction appears in “A” range, regard it as “d2 ”.

If it exceeds the limit (large difference in dimensions), replace it
with a new one.

INSTALLATION
NOTE:
The figure shows the relationship between the mating mark on each
timing chain and that on the corresponding sprocket, with the com-
ponents installed.
1. Make sure that crankshaft key points straight up.
2. Tighten mounting bolts in numerical order as shown in figure
with the following procedure, and install balancer unit.
CAUTION:
If mounting bolts are re-used, check their outer diameter
before installation. Refer to EM-50, "
INSPECTION AFTER
REMOVAL" .
a. Apply new engine oil to threads and seat surfaces of mounting
bolts.
b. Tighten all bolts.
c. Turn all bolts 90 degrees clockwise (angle tightening).
d. Completely loosen.
CAUTION:
In this step, loosen bolts in reverse order as shown in the
figure.
e. Tighten all bolts.
f. Turn them another 90 degrees clockwise (angle tightening).
CAUTION:
Check tightening angle with an angle wrench (special service tool) or a protractor. Do not make
judgment by visual check alone.
