REPLACE TIMING BELT

(a) Remove the timing belt.

(See page

EG–46

)

(b) Install the timing belt.

(See page

EG–59

)

INSPECT DRIVE BELT
HINT: A belt tensioner is used, so checking the belt tension
is not necessary.

(a) Visually

check the drive belt for excessive wear, frayed cords,

etc.
If necessary, replace the drive belt.
HINT:

•

Cracks on the rib side of a drive belt are considered
acceptable. If the drive belt has chunks missing from the
ribs, it should be replaced.

•

The drive belt tension can be released by turning the
belt tensioner counterclockwise. The pulley bolt for the
belt tensioner has a left–hand thread.

(b) Check the belt tensioner operation.

•

Check that the belt tensioner moves downward when
the drive belt is pressed down at the points indicated in
the illustration with approx. 98 N (10 kgf, 22.0 lbf) of
force.

•

Check the alignment of the belt tensioner pulley to make
sure the drive belt will not slip off the pulley.

If necessary, replace the belt tensioner.

•

Check that the arrow mark on the belt tensioner falls
within area A of the scale.

If it is outside area A, replace the drive belt.
HINT:

•

When a new belt is installed, it should lie within area B.
If not, the drive belt is not correct.
