TIMING BELT ASSEMBLY

7) Install the belt cover. 
<Ref. to ME(H4DOSTC)-46, INSTALLATION, Belt
Cover.>
8) Install the crankshaft pulley. 
<Ref. to ME(H4DOSTC)-44, INSTALLATION,
Crankshaft Pulley.>
9) Install the V-belt. 
<Ref. to ME(H4DOSTC)-42, INSTALLATION, V-
belt.>

C: INSPECTION

1. TIMING BELT

1) Check the timing belt teeth for breaks, cracks,
and wear. If any fault is found, replace the belt.
2) Check the condition of back side of belt; if any
crack is found, replace the belt.

NOTE:
• Be careful not to let oil, grease or coolant contact
the belt. Remove quickly and thoroughly if this hap-
pens.
• Do not bend the belt sharply.

Bending radius: h

60 mm (2.36 in) or more

2. AUTOMATIC BELT TENSION ADJUST-
ER

1) Visually check the oil seals for leaks, and rod
ends for abnormal wear or scratches. If necessary,
replace the automatic belt tension adjuster assem-
bly.

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 lb) 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 lb), check it using
the following procedures:

(1) Slowly press the adjuster rod down to the
end surface of the cylinder. Repeat this motion 2
or 3 times.

(2) With the adjuster rod moved all the way up,
apply a pressure of 294 N (30 kgf, 66 lb) to it.
Check the adjuster rod stiffness.
(3) If the the adjuster rod is not stiff and moves
down, replace the automatic belt tension adjust-
er assembly with a new one.

NOTE:
• 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-in the push adjuster rod gradually taking
more than 3 minutes.
• Do not allow press pressure to exceed 9,807 N
(1,000 kgf, 2,205 lb).
• Press the adjuster rod as far as the end surface
of the cylinder. Do not press the adjuster rod into
the cylinder. Doing so may damage the cylinder.
4) Measure the extension of rod beyond the body.
If it is not within specifications, replace with a new
one.

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 belt tension pulley if faulty.
2) Check the belt tension pulley for smooth rota-
tion. Replace if noise or excessive play is noted.
3) Check the belt tension pulley for grease leakage.

4. BELT IDLER

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