the crank angle sensor with the mating mark (notch) in
the plate.
(2) Install the crank angle sensor to the engine.
Caution
When tightening the nut of the crankshaft angle
sensor, make sure that the crank angle sensor does
not turn.(3) Check that the ignition timing is set at the standard
value. (Refer to GROUP

(1) Using a wrench, hold the camshaft at its hexagon
(between the
No.2 and No.3 journals) and remove the
camshaft sprocket bolt.
Caution
Locking the camshaft sprocket with a tool damages
the sprocket.
(2) Remove the camshaft sprockets.

INSPECTIONCAMSHAFT
h(1) Visually check the camshaft journal surfaces and replace if
_damage or seizure is evident.
If the journal is seized, check the cylinder head for possibledamage. Check also for clogged oil holes in the cylinder
head.
(2) Check cams for excessive wear and damage and replace if
defects are evident. Measure the cam height and replace ifthe limit is not reached.

ROCKER ARM
(1) Visually check the roller and replace if dent, damage, or
seizure is evident.
(2) Check the roller for smooth rotation. Replace if it binds or
there is an excessive play.
(3) Check the valve contact surface for possible damage or
seizure and replace as necessary.
SERVICE POINTS OF REASSEMBLYNOSLGAB10. INSTALLATION OF CAMSHAFT
(1) Apply engine oil to journals and cams of the camshafts.
(2) Install the camshafts on the cylinder head.
Use care not to confuse the intake camshaft with the
exhaust one. The intake camshaft has a slit on its rear
end for driving the crank angle sensor.
(3) Make also sure that the dowel pins on the camshaft
sprocket end are located on the top.
9./8./7./6./4./3. INSTALLATION OF BEARING CAPS
(1) Bearing cap Nos.2 to 5 are of the same shape. At
installation, check with the markings on the caps of capnumber and intake/exhaust identification symbol. Only
“I” or “E” is stamped on No. 1 bearing cap.4I

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.
