B: INSPECTION
1. TIMING BELT
1) Check timing belt teeth for breaks, cracks and
wear. If any fault is found, replace belt.
2) Check the condition of back side of belt; if any
crack is found, replace belt.
CAUTION:
IBe careful not to let oil, grease or coolant
contact the belt. Remove quickly and thor-
oughly if this happens.
IDo not bend the belt sharply.

2. AUTOMATIC BELT TENSION
ADJUSTER
1) Visually check oil seals for leaks, and rod ends
for abnormal wear or scratches. If necessary,
replace automatic belt tension adjuster assembly.
CAUTION:
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 kg, 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 kg, 66 lb), check it using
the following procedures:

[W2B2]2-3bSERVICE PROCEDURE
2. Timing Belt

(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 kg, 66 lb) to it.
Check adjuster rod stiffness.
(3) If the adjuster rod is not stiff and moves
down, replace the automatic belt tension
adjuster assembly with a new one.
CAUTION:
IAlways use a vertical type pressing tool to
move the adjuster rod down.
IDo not use a lateral type vise.
IPush adjuster rod vertically.
IPress-in the push adjuster rod gradually tak-
ing more than three minutes.
IDo not allow press pressure to exceed 9,807
N (1,000 kg, 2,205 lb).
IPress the adjuster rod as far as the end sur-
face 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 mating surfaces of timing belt and con-
tact point of adjuster rod for abnormal wear or
scratches. Replace belt tension pulley if faulty.
2) Check belt tension pulley for smooth rotation.
Replace if noise or excessive play is noted.
3) Check belt tension pulley for grease leakage.
4. BELT IDLER
1) Check idler for smooth rotation. Replace if
noise or excessive play is noted.
2) Check outer contacting surfaces of idler pulley
for abnormal wear and scratches.
3) Check idler for grease leakage.
5. SPROCKET
1) Check sprocket teeth for abnormal wear and
scratches.
2) Make sure there is no free play between
sprocket and key.
3) Check crankshaft sprocket notch for sensor for
damage and contamination of foreign matter.

1) Preparation for installation of automatic belt
tension adjuster assembly:
CAUTION:
IAlways use a vertical type pressing tool to
move the adjuster rod down.
IDo not use a lateral type vise.
IPush adjuster rod vertically.
IBe sure to slowly move the adjuster rod
down applying a pressure of 294 N (30 kg, 66

IPress the adjuster rod as far as the end sur-
face of the cylinder. Do not press the adjuster
rod into the cylinder. Doing so may damage the
cylinder.
IDo not release press pressure until stopper
pin is completely inserted.
(1) Attach the automatic belt tension adjuster
assembly to the vertical pressing tool.
(2) Slowly move the adjuster rod down with a
pressure of 294 N (30 kg, 66 lb) until the
adjuster rod is aligned with the stopper pin hole
in the cylinder.
