8) Install the crank pulley. 55, INSTALLATION, Crank Pulley.>
9) Install the V-belt. STALLATION, 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 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.
Rod extension: H
6.2
±0.5 mm (0.244±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 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 belt 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 belt idler for grease leakage.

A: INSPECTION
NOTE*:
When disconnecting the fuel injector connector, Malfunction Indicator Light illuminates and DTC is stored in
ECM memory.
Therefore, carry out the CLEAR MEMORY MODE Mode.> and INSPECTION MODE after con-
necting the fuel injector connector.
Type of sound Condition Possible cause
Regular clicking soundSound increases as engine
speed increases. Valve mechanism is defective.
 Incorrect valve clearance
 Worn valve rocker
 Worn camshaft
 Broken valve spring
Heavy and dull clankOil pressure is low. Worn crankshaft main bearing
 Worn connecting rod bearing (big end)
Oil pressure is normal. Loose flywheel mounting bolts
 Damaged engine mounting
High-pitched clank (Spark
knock)Sound is noticeable when
accelerating with an overload. Ignition timing advanced
 Accumulation of carbon inside combustion chamber
 Wrong heat range of spark plug
 Improper octane number of gasoline
Clank when engine speed is
medium (1,000 to 2,000 rpm).Sound is reduced when fuel
injector connector of noisy cyl-
inder is disconnected.
(NOTE*) Worn crankshaft main bearing
 Worn bearing at crankshaft end of connecting rod
Knocking sound when engine
is operating under idling speed
and engine is warmSound is reduced when fuel
injector connector of noisy cyl-
inder is disconnected.
(NOTE*) Worn cylinder liner and piston ring
 Broken or stuck piston ring
 Worn piston pin and hole at piston end of connecting rod
Sound is not reduced if each
fuel injector connector is dis-
connected in turn. (NOTE*) Unusually worn valve lifter
 Worn cam gear
 Worn camshaft journal bore in crankcase
Squeaky sound —  Insufficient generator lubrication
Rubbing sound —  Defective generator brush and rotor contact
Gear scream when starting
engine— Defective ignition starter switch
 Worn gear and starter pinion
Sound like polishing glass with
a dry cloth— Loose drive belt
 Defective water pump shaft
Hissing sound — Loss of compression
 Air leakage in air intake system, hoses, connections or mani-
folds
Timing belt noise — Loose timing belt
 Belt contacting case/adjacent part
Valve tappet noise —  Incorrect valve clearance

5) Disconnect the connector from ignition coil.
6) Remove the ignition coil.
7) Remove the spark plugs with the spark plug
sockets.
B: INSTALLATION
1. RH SIDE

⋅m (1.6 kgf-m, 11.7 ft-lb)
NOTE:
The above torque should be only applied to new
spark plugs without oil on their threads.
In case their threads are lubricated, the torque
should be reduced by approx. 1/3 of the specified
torque in order to avoid over-stressing.
2. LH SIDE

C: INSPECTION
Check the electrodes and inner and ceramic insu-
lator of plugs, noting the type of deposits and the
degree of electrode erosion.

Brown to grayish-tan deposits and slight electrode
wear indicates correct spark plug heat range.
