>>D<< THRUST CAMSHAFT BEARING
CAP/CAMSHAFT BEARING CAP/OIL FEEDING
CAMSHAFT BEARING CAP INSTALLATION

1. Install the camshaft bearing caps to the cylinder heads.

NOTE: Because the thrust camshaft bearing cap and cam-
shaft bearing cap are the same in shape, check the bearing
cap number and additionally its symbol to identify the intake
and exhaust sides for correct installation.

2. Tighten each camshaft bearing cap mounting bolt to the

specified torque in the order of number shown in the figure
in two or three steps.

Tightening torque: 12

± 1 N⋅ m (107 ± 8 in-lb)

.

>>E<< FRONT CAMSHAFT BEARING CAP
ASSEMBLY INSTALLATION

CAUTION

When the mounting bolts are tightened with the front cam-
shaft bearing cap tilted, the front camshaft bearing cap is
damaged. Install the front camshaft bearing cap properly
to the cylinder head and camshaft.
1. Install the front camshaft bearing cap to the cylinder head,

and temporarily tighten the front camshaft bearing cap to the
specified torque in the order of the figure (1).

Tightening torque: 17

± 3 N⋅ m (13 ± 2 ft-lb)

2. Tighten the front camshaft bearing cap again to the specified

torque in the order of the figure (2).

Tightening torque: 30

± 2 N⋅ m (23 ± 1 ft-lb)

CAUTION

• When pushing in the retainer of the fuel high-pressure

hose connector, pay attention to avoid damage to the
retainer.

• After the installation of the fuel high-pressure hose,

slightly pull the fuel high-pressure hose to check that it
is connected securely. At this time, also check that
there is approximately 1 mm (0.04inch) play.

1. Securely insert the fuel rail stopper into the fuel

high-pressure hose connector groove to install the fuel
high-pressure hose to the fuel rail.

2. Push in the retainer of the fuel high-pressure hose

connector to lock the fuel high-pressure hose and fuel rail.
