1(2) Tighten the bearing caps in the order shown two to
three times by torquing progressively.
Tighten to specification in the final sequence.
(3) Check to be sure that the rocker arm is correctly placedon the lash adjuster and valve stem end.
5. INSTALLATION OF CAMSHAFT OIL SEAL
(1) Install the special tool, Guide, on the camshaft.
(2) Apply oil to the oil seal and insert the seal along the
Guide until it contacts the cylinder head.
(3) Using the special tool, Installer, press-fit the oil seal intothe cylinder head.
2. INSTALLATION OF CAMSHAFT SPROCKET
Using a wrench hold the camshaft at its hexagon (betweenthe
No.2 and No.3 journals) and tighten the bolt to
specification.Caution
Locking the camshaft sprocket with a tool damages the
sprocket.1. INSTALLATION OF CRANK ANGLE SENSOR
(1) Locate the dowel pin on the sprocket side of the intake
camshaft at top.
(2) Align the punch mark on the crank angle sensor housingwith the notch in plate.
NOTE
The crank angle sensor can be installed even when thepunch mark is positioned opposite the notch; however,
the position results in incorrect fuel injection and
ignition timings.
(3) Install the crank angle sensor on the cylinder head.

VALVE INSPECTIONNllGGAA
(1) Operation check
Using a hand
vaccum pump, apply a negative pressure to
the solenoid valve nipple on which the white vacuum hose
is connected, and check air-tightness when the voltage is
applied to the solenoid valve terminal and when it i‘s releasedfrom the terminal.
