REMOVAL SERVICE POINTS

.

<<A>> FRONT CAMSHAFT BEARING CAP / CAM-
SHAFT BEARING CAP REMOVAL

CAUTION

Loosing the installation bolts for the camshaft bearing cap
at the same time causes the valve spring force, which
makes the installation bolts jump out, resulting in the dam-
aged threads. Always loose them four or five times.
First remove a mounting bolt of the front camshaft bearing cap
and then a mounting bolt of each camshaft bearing cap in the
order shown in the illustration.

.

<<B>> VALVE TAPPET REMOVAL

Pick out valve tappets with fingers and store removed valve
tappets with tags describing the installed position attached for
reassembly.

INSTALLATION SERVICE POINTS

.

>>A<< VALVE TAPPET INSTALLATION

3. The identification mark of the camshaft bearing is painted at

the illustrated position.

4. Set the dowel pins of the camshaft at the illustrated

positions.

5. Camshaft bearing caps Number 1 to Number 4 are of the

same shape. Install them upon checking the identification
mark so as not to misidentify cap Number and to confuse
the intake side with the exhaust side.

7. Tighten each front camshaft bearing cap mounting bolt to

the temporarily torque of 17

± 3 N⋅m (14 ± 2 ft-lb) in the order

of number shown (1).

8. Tighten each front camshaft bearing cap mounting bolt to

the specified tightening torque of 30

± 2 N⋅m (22 ± 1 ft-lb) in

the order of number shown (2).

>>C<< O-RING / ENGINE OIL CONTROL VALVE
INSTALLATION

CAUTION

• The O-ring must not be reused.
• Wind non-adhesive tape (seal tape, etc.) around the

notch of the oil passage of the oil feeder 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 oil

feeder control valve.

2. Install the oil feeder control valve on the cylinder head.
3. Tighten the oil feeder control valve to the specified

tightening torque of 10

± 2 N⋅m (89 ± 17 in-lb).
