BEARING CAP
INSTALLATION
Tighten the bearing cap installation bolts to the torque
in two or three steps.
C a u t i o n
Tighten uniformly, otherwise the rocker arms not
straight.

CAMSHAFT OIL SEAL INSTALLATION
Use the special tool to drive the camshaft oil seal into position
carefully.
CAMSHAFT POSITION SENSING CYLINDER/
CAMSHAFT POSITION SENSOR SUPPORT
INSTALLATION
(1) Install the camshaft position sensing cylinder to the end
of the camshaft as shown in the illustration.
(2) Install the camshaft position sensor support.
(3)Check that the identification paint on the
sensing cylinder is pointing in the same direction as the,
camshaft position sensor installation direction when
camshaft is at the No. 1 compression TDC position.
