>>A<< ENGINE OIL PRESSURE SWITCH INSTAL-
LATION

AK502866AD

CAUTION

• Do not allow sealant to squeeze out to the screw tip.
• Do not exceed the specified torque.

1. Completely remove sealant adhering to the engine oil

pressure switch and cylinder block threaded holes.

2. Apply sealant (Three bond 1215, Three bond 1212D or

equivalent) of 5 mm (0.2 inch) to the threaded portion of the
engine oil pressure switch shown in the illustration.

3. Tighten the engine oil pressure switch to the cylinder block

to the specified torque.

Specified torque: 10

± 2 N⋅ m (89 ± 17 in-lb)

.

>>D<< O-RING INSTALLATION

AK502784AD

MB992106

When inserting an O-ring into the injector on the injection noz-
zle side, use special tool MB992106 to gradually expand the
O-ring, and fit it in place.

.

>>E<< INJECTOR / O-RING / INJECTOR
SUPPORT INSTALLATION

CAUTION

Do not allow gasoline to enter the fuel rail.
1. Apply gasoline to the O-ring of the injector.
2. Insert the injector into the fuel rail while rotating the injector

from side to side, taking care not to damage the O-ring.

3. Check that the injector rotates smoothly. If it does not rotate

smoothly, the O-ring may be caught. Remove the injector
and check the O-ring for damage. Then, insert it again into
the fuel rail and check.

AK502744

4. Make sure that the protrusion of the injector is at the center

as shown in the illustration.

AK502745

5. Securely assemble the injector to the injector groove and

fuel rail collar.

.

>>F<< FUEL RAIL ASSEMBLY INSTALLATION

1. Apply gasoline to the pressure side O-ring of the injector.
2. Tighten the fuel rail assembly to the intake manifold to the

specified torque.

Specified torque: 12

± 3 N⋅ m (106 ± 26 in-lb)

.
