b. Push in chain tensioner plunger. Insert a stopper pin into hole on
chain tensioner body to secure chain tensioner plunger and
remove chain tensioner.
NOTE:
Use approximately 0.5 mm (0.02 in) dia. hard metal pin as a
stopper pin.
c. Secure hexagonal part of camshaft with a wrench. Loosen cam-
shaft sprocket mounting bolts and remove camshaft sprockets.
CAUTION:
Do not rotate crankshaft or camshaft while timing chain is
removed. It causes interference between valve and piston.
NOTE:
Chain tension holding work is not necessary. Crankshaft
sprocket and timing chain do not disconnect structurally while
front cover is attached.
8. Remove camshaft position sensor (PHASE) from cylinder head back side.
CAUTION:

Handle carefully to avoid dropping and shocks.

Do not disassemble.

Do not allow metal powder to adhere to magnetic part at sensor tip.

Do not place sensor in a location where it is exposed to magnetism.
9. Loosen mounting bolts in reverse order as shown in the figure,
and remove camshaft brackets and camshafts.

Remove camshaft bracket (No. 1) by slightly tapping it with a
plastic hammer.
10. Remove valve lifters.

Identify installation positions, and store them without mixing them up.
INSPECTION AFTER REMOVAL
Camshaft Runout
1. Put V-block on a precise flat table, and support No. 2 and 5 jour-
nal of camshaft.
CAUTION:
Do not support No. 1 journal (on the side of camshaft
sprocket) because it has a different diameter from the other
four locations.
2. Set dial indicator vertically to No. 3 journal.
3. Turn camshaft to one direction with hands, and measure the
camshaft runout on dial indicator. (Total indicator reading)

Measure the outer diameter of valve lifter with a micrometer.
VALVE LIFTER HOLE DIAMETER
Measure the diameter of valve lifter hole of cylinder head with an
inside micrometer.
VALVE LIFTER CLEARANCE

(Valve lifter clearance) = (Valve lifter hole diameter) – (Valve
lifter outer diameter)

If out of the standard, referring to the each standard of valve
lifter outer diameter and valve lifter hole diameter, replace either
or both valve lifter and cylinder head.
INSTALLATION
1. Install valve lifters.

Install them in the original positions.
2. Install camshafts.

Distinction between intake and exhaust camshafts is per-
formed with the different shapes of rear end.

Install camshafts so that camshaft dowel pins on the front side
are positioned as shown in the figure.
3. Install camshaft brackets with the following procedure:
a. Remove foreign material completely from camshaft bracket backside and from cylinder head installation
face.Standard: 33.965 - 33.980 mm (1.3372 - 1.3378 in)

4. Tighten mounting bolts of camshaft brackets in the following
steps, in numerical order as shown in the figure.
a. Tighten No. 9 to 11 in numerical order.
b. Tighten No. 1 to 8 in numerical order.
c. Tighten all bolts in numerical order.
d. Tighten all bolts in numerical order.
CAUTION:
After tightening mounting bolts of camshaft brackets, be sure to wipe off excessive liquid gasket
from the parts listed below.

Mating surface of rocker cover.

Mating surface of front cover. (When installed without front cover)
5. Install camshaft position sensor (PHASE).
6. Install camshaft sprockets.

Install them by aligning the mating marks on each camshaft
sprocket with the ones painted on timing chain link plate dur-
ing removal.
CAUTION:

Aligned mating marks could slip. Therefore, after
matching them, hold the timing chain in place by hand.

Before and after installing chain tensioner, make sure
again that mating marks have not slipped.
NOTE:
Before installation of chain tensioner, it is possible to re-match
the marks on timing chain with the ones on each sprocket.
7. Install chain tensioner.
CAUTION:
After installation, pull the stopper pin off completely, and make sure that chain tensioner plunger
is released.
8. Install chain guide.
9. Install intake valve timing control cover with the following procedure:
a. Install intake valve timing control solenoid valve to intake valve timing control cover if removed.
b. Install oil rings to the camshaft sprocket (INT) insertion points on backside of intake valve timing control
cover.
c. Install O-ring to front cover.
d. Apply liquid gasket with a tube presser (special service tool:
WS39930000) to intake valve timing control cover as shown in
the figure.
Use Genuine Liquid Gasket or equivalent. : 2.0 N·m (0.2 kg-m, 1 ft-lb)
