DRIVE BELTS

DRIVE BELTSPFP:02117
Checking Drive BeltsBBS0058S
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 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 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 AdjustmentBBS0058T
Belt tensioning is not necessary, as it is automatically adjusted by drive belt auto-tensioner.
Removal and InstallationBBS0058U
REMOVAL
1. Remove splash guard (RH).
2. With box wrench, and while securely holding the hexagonal part
in center of drive belt auto-tensioner pulley, move the wrench
handle in the direction of arrow (loosening direction of ten-
sioner).
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.

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 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-14, "
Checking Drive Belts" .
Removal and Installation of Drive Belt Auto-TensionerBBS0058V
CAUTION:
The complete drive belt auto-tensioner must be replaced as a unit, including the pulley.
REMOVAL

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.

INSPECTION AFTER INSTALLATION
Make sure there are no fuel leaks at connections with the following procedure:
1. Apply fuel pressure to fuel lines with turning ignition switch “ON” (with engine stopped). Then make sure
there are no fuel leaks at connections.
NOTE:
Use mirrors for checking on invisible points.
2. Start engine. With engine speed increased, make sure again there are no fuel leaks at connections.
CAUTION:
Do not touch the engine immediately after stopped as engine becomes extremely hot.
