6. Abnormally worn belt sides;

NOTE: belt sides are normal if they have
“knife-cut” surfaces.

7. Badly worn teeth.
Initial stage: Canvas is worn (canvas fiber is fluffy;
teeth look whitish due to worn-out rubber; canvas
texture is unclear)
Second stage: Canvas is lost and rubber is exposed
(tooth width narrows down)
8. Missing tooth.

AUTO-TENSIONER

1. Check the auto-tensioner for leaks from the

sealed sections.
Replace it if leaky.

2. Check the rod end for wear and other damage.

Replace the auto-tensioner if the rod is badly
worn or damaged.

3. Measure the extension length of the rod.

If it is not within the standard value range, replace
the auto-tensioner.

Standard value: 12 mm

4. Press the rod with a force of 98 to 196 N and

measure the amount of retraction. If the
measurement exceeds the standard value,

INSTALLATION SERVICE POINTS
>>A<< INJECTOR INSTALLATION

1. Apply a thin coat of engine oil to a new O-ring.

CAUTION

Prevent engine oil from getting into the delivery
pipe.
2. Insert the injector into the delivery pipe while

turning it in both directions carefully not to
damage the O-ring.

3. Check that the injector turns smoothly. If it does

not, the O-ring may be jamming, so remove the
injector and check the O-ring for damage. If the
O-ring is intact, insert the injector into the delivery
pipe and check it for smooth rotation again.

>>B<< FUEL PRESSURE REGULATOR
INSTALLATION

1. Apply a thin coat of engine oil to a new O-ring.

CAUTION

Prevent engine oil from getting into the delivery
pipe.
2. Insert the fuel pressure regulator into the delivery

pipe while turning it in both directions carefully not
to damage the O-ring.

3. Check that the fuel pressure regulator turns

smoothly. If it does not, the O-ring may be
jamming, so remove the fuel pressure regulator
and check the O-ring for damage. If the O-ring is
intact, insert it into the delivery pipe and check it
for smooth rotation again.

>>C<< THROTTLE BODY GASKET
