2. AUTOMATIC BELT TENSION ADJUST-
ER

1) Visually check the oil seals for leaks, and rod
ends for abnormal wear and scratches. If neces-
sary, replace the automatic belt tension adjuster
assembly.

NOTE:
Slight traces of oil at rod’s oil seal does not indicate
a problem.
2) Check that the adjuster rod does not move when
a pressure of 294 N (30 kgf, 66 lbf) is applied to it.
This is to check adjuster rod stiffness.
3) If the adjuster rod is not stiff and moves freely
when applying 294 N (30 kgf, 66 lbf), check it using
the following procedures:

(1) Slowly press the adjuster rod down to the
end surface of the cylinder. Repeat this opera-
tion two to three times.
(2) With the adjuster rod moved all the way up,
apply a pressure of 294 N (30 kgf, 66 lbf) to it.
Check the adjuster rod stiffness.
(3) If the adjuster rod is not stiff and moves
down, replace the automatic belt tension adjust-
er assembly with a new one.

CAUTION:
• Always use a vertical type pressing tool to
move the adjuster rod down.
• Do not use a lateral type vise.
• Push the adjuster rod vertically.
• Press the adjuster rod gradually taking more
than three minutes.
• Do not allow press pressure to exceed 9,807
N (1,000 kgf, 2,205 lbf).
• Press the adjuster rod as far as the end sur-
face of cylinder. Do not press the adjuster rod
into cylinder. Doing so may damage the cylin-
der.
4) Measure the amount of rod protrusion beyond
the body. If it is not within specifications, replace
with a new one.

Amount of rod protrusion H:

5.7

±

0.5 mm (0.224

±

0.020 in)

3. BELT TENSION PULLEY

1) Check the mating surfaces of timing belt and
contact point of adjuster rod for abnormal wear or
scratches. Replace the automatic belt tension ad-
juster assembly if faulty.
2) Check the belt tension pulley for smooth rota-
tion. Replace if noise or excessive play occurs.
3) Check the belt tension pulley for grease leakage.

4. BELT IDLER

1) Check the belt idler for smooth rotation. Replace
if noise or excessive play occurs.
2) Check the outer contacting surfaces of idler pul-
ley for abnormal wear and scratches.
3) Check the belt idler for grease leakage.
