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:
Be careful not to let oil, grease or coolant contact
the belt. Remove quickly and thoroughly if this hap-
pens.
G2M0115
Do not bend the belt sharply.
Bending radius: h
60 mm (2.36 in) or more
2. BELT TENSION ADJUSTER
1) Visually check oil seals for leaks, and rod ends for
abnormal wear or scratches. If necessary, replace belt ten-
sion adjuster.
CAUTION:
Slight traces of oil at rod’s oil seal does not indicate a
problem.
2) While holding tensioner with both hands, push the rod
section against floor or wall ensuring the rod section will
react as follows:
(1) When applying a force of 147 N (15 kg, 33 lb), the
rod section should not sink.
(2) When applying a force of 147 to 490 N (15 to 50 kg,
33 to 110 lb), the rod section should maintain a projec-
tionally acting force and should not sink within 8.5 sec-
onds.

3) Measure the extension of rod beyond the body. If it is
not within specifications, replace with a new one.
Rod extension: H
15.4 — 16.4 mm (0.606 — 0.646 in)
3. BELT TENSIONER
1) Check mating surfaces of timing belt and contact point
of tension adjuster rod for abnormal wear or scratches.
Replace belt tensioner if faulty.
2) Check spacer and tensioner bushing for wear.
3) Check tensioner for smooth rotation. Replace if noise or
excessive play is noted.
4) Check tensioner 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.
