•
AK303651AF
Tape
Wind non-adhesive tape (seal tape, etc.) around the
notch of the oil passage of the engine oil control valve
before installing the O-ring to prevent damage. Damage
to the O-ring causes oil leakage.
1. Apply a small amount of engine oil to the O-ring of the
engine oil control valve.
2. Install the engine oil control valve on the cylinder head.
3. Tighten the engine oil control valve to the specified torque.
Specified torque: 10
± 2 N⋅ m (89 ± 17 in-lb)

Measure camshaft height (camshaft major axis). If the height is
less than the limit, replace the camshaft.
Standard value:
Intake: 44.1 mm (1.74 inches)
Exhaust: 45.0 mm (1.77 inches)
Limit:
Intake: 43.6 mm (1.72 inches)
Exhaust: 44.5 mm (1.75 inches)

3. Put straightly the plastigage having the length of the bearing
width on the journal axis, centering the axis.
4. Carefully install the bearing cap.Tighten the bolt as
instructed in >>B<< Bolt Installation Point.
5. Remove the bolt and the bearing cap carefully.

Plastigage
AD
6. Measure the plastigage whose width is most compressed
using the scale printed on the plastigage bag. When the
measured value deviates from the standard one, replace the
bearing.
Standard value: 0.035
− 0.072 mm (0.0014 − 0.0028 inch)
CAUTION
When the bearing is used again, be careful not to reverse
the cylinder head side and the camshaft side during instal-
lation.
