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.

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" .
