CheckingINFOID:0000000001381384
 Inspection should be done only when engine is cold or over 30
minutes after the engine is stopped.
 Visually check belts for wear, damage, and cracks on inside and
edges.
 Turn crankshaft pulley two time clockwise, and make sure tension on all pulleys is equal before doing the
test.
 When measuring deflection, apply 98 N (10 kg, 22 lb) at the ( ) marked point.
 Measure the belt tension and frequency with acoustic tension gauge (commercial service tool) at the ( )
marked point.
CAUTION:
 When the tension and frequency are measured, the acoustic tension gauge should be used.
 When checking immediately after installation, first adjust it to the specified value. Then, after turning
crankshaft two turns or more, re-adjust to the specified value to avoid variation in deflection
between pulleys.
Tension AdjustmentINFOID:0000000001381385
CAUTION:
 When belt is replaced with new one, adjust belt tension to the value for “New belt”, because new belt
will not fully seat in the pulley groove.
 When tension of the belt being used exceeds “Limit”, adjust it to the value for “After adjusted”.
 When installing a belt, make sure it is correctly engaged with the pulley groove.
 Never allow oil or engine coolant to get on the belt.
 Never twist or bend the belt strongly.
1. Loosen the idler pulley lock nut (A) from the tightening position
with the specified torque by 45 degrees.

CAUTION:
 When the lock nut is loosened excessively, the idler pulley tilts and the correct tension adjust-
ment cannot be performed. Never loosen it excessively (more than 45 degrees).
 Put a matching mark on the lock nut, and check turning angle with a protractor. Never visually
check the tightening angle.
2. Adjust the belt tension by turning the adjusting bolt.
CAUTION:
 When checking immediately after installation, first adjust it to the specified value. Then, after
turning crankshaft two turns or more, re-adjust to the specified value to avoid variation in deflec-
tion between pulleys.
 When the tension adjustment is performed, the lock nut should be in the condition at step“2”. If
the tension adjustment is performed when the lock nut is loosened more than the standard, the
idler pulley tilts and the correct tension adjustment cannot be performed.
3. Tighten the idler pulley lock nut.

 Perform the belt tension adjustment with the lock nut temporarily tightened at the step “1” so as
not to tilt the idler pulley.
 When checking immediately after installation, first adjust it to the specified value. Then, after
turning crankshaft two turns or more, re-adjust to the specified value to avoid variation in deflec-
tion between pulleys.

Inspection and AdjustmentINFOID:0000000001381391
INSPECTION
Perform inspection as follows after removal, installation or replacement of camshaft or valve-related parts, or if
there is unusual engine conditions regarding valve clearance.
1. Remove rocker cover. Refer to EM-47, "
Exploded View".
2. Measure the valve clearance with the following procedure:
a. Set No. 1 cylinder at TDC of its compression stroke.
 Rotate crankshaft pulley (2) clockwise and align TDC mark
(without paint mark) (A) to timing indicator (1) on front cover.
 At the same time, make sure that both intake and exhaust cam
noses of No. 1 cylinder face outside as shown.
 If they do not face outside, rotate crankshaft pulley once more
(360 degrees) and align as shown.
b. Use a feeler gauge, measure the clearance between valve lifter
and camshaft.
 By referring to the figure, measure the valve clearances at
locations marked “×” as shown in the table below [locations
indicated with black arrow ( ) shown] with a feeler gauge.

3. If out of standard, perform adjustment procedure.
ADJUSTMENT
 Perform adjustment depending on selected head thickness of valve lifter.
1. Remove camshaft. Refer to EM-59, "
Exploded View".
2. Remove valve lifters at the locations that are out of the standard.
3. Measure the center thickness of the removed valve lifters with a
micrometer (A).

 Thickness of new valve lifter (B) can be identified by stamp
mark (A) on the reverse side (inside the cylinder).
 Stamp mark “300” indicates 3.00 mm (0.118 in) in thickness.
NOTE:
Available thickness of valve lifter: 26 sizes range 3.00 to 3.50 mm (0.1181 to 0.1378 in) in steps of 0.02
mm (0.0008 in) (when manufactured at factory). Refer to EM-123, "
Camshaft".
5. Install the selected valve lifter.
6. Install camshaft. Refer to EM-59, "
Exploded View".
7. Manually rotate crankshaft pulley a few rotations.
8. Make sure that valve clearances for cold engine are within specifications by referring to the specified val-
ues.
9. Install all removed parts in the reverse order of removal.
10. Warm up the engine, and check for unusual noise and vibration.
