Apply liquid gasket on installation position of water pump and cylinder head very completely.
5. Align rear timing chain case and water pump assembly with dowel pins (right and left) on cylinder block
and install case.

Make sure O-rings stay in place during installation to cylinder block and cylinder head.
a. Tighten mounting bolts in the numerical order as shown in the
figure.

There are two bolt lengths used. Follow the below for proper
bolt length specifications.
b. After all bolts are temporarily tightened, retighten them to the
specification in the numerical order as shown in the figure.

If RTV Silicone Sealant protrudes, wipe it off immediately.Bolt length: Bolt position
20 mm (0.79 in) : 1, 2, 3, 6, 7, 8, 9, 10

6. After installing rear timing chain case, check surface height dif-
ference between following parts on oil pan mounting surface.

If not within standard, repeat above installation procedure.
7. Position crankshaft so No. 1 piston is set at TDC on the com-
pression stroke.

Make sure that dowel pin hole, dowel pin and crankshaft key
are located as shown in the figure.
NOTE:
Though camshaft does not stop at position as shown in the
figure, for the placement of cam nose, it is generally accepted
camshaft is placed for the same direction of the figure.
CAUTION:
Hole on small dia. side must be used for intake side dowel pin hole. Do not misidentify (ignore
big dia. side).
8. Install timing chains (secondary) and camshaft sprockets.
CAUTION:
Matching marks between timing chain and sprockets slip
easily. Confirm all matching mark positions repeatedly dur-
ing the installation process.
a. Push plunger of secondary chain tensioner and keep it pressed
in with a stopper pin.Standard (Rear timing chain case to cylinder block):
–0.24 to 0.14 mm (–0.0094 to 0.0055 in)

REMOVAL
1. Remove front timing chain case, camshaft sprocket, timing chain and rear timing chain case. Refer to EM-
63, "TIMING CHAIN" .
2. If necessary, remove camshaft position sensor (PHASE) (right
and left banks) 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 sensors in a location where they are
exposed to magnetism.
3. Remove intake valve timing control solenoid valve from No.1
camshaft bracket.
4. Remove intake and exhaust camshaft brackets.

Mark camshafts, camshaft brackets, and bolts so they are
placed in the same position and direction for installation.

Equally loosen camshaft bracket bolts in several steps in the
reverse order as shown in the figure.
5. Remove camshaft.
6. Remove valve lifter.

Identify installation positions, and store them without mixing them up.

7. Remove secondary timing chain tensioner from cylinder head.

Remove chain tensioner with its stopper pin attached.
NOTE:
Stopper pin was attached when secondary timing chain was
removed.
INSPECTION AFTER REMOVAL
Camshaft Runout
1. Put V block on precise flat bed, and support No. 2 and No. 4
journal of camshaft.
CAUTION:
Do not support journal No. 1 (on the side of camshaft
sprocket) because it has a different diameter from the other
three locations.
2. Set dial gauge vertically to No. 3 journal.
3. Turn camshaft to one direction with hands, and measure cam-
shaft runout on dial gauge. (Total indicator reading)
4. If it exceeds the standard, replace camshaft.
Camshaft Cam Height
1. Measure camshaft cam height.
2. If wear is beyond the limit, replace camshaft.
Camshaft Journal Oil Clearance
Outer Diameter of Camshaft Journal
Measure outer diameter of camshaft journal.
Inner Diameter of Camshaft Bracket

Tighten camshaft bracket bolt with specified torque. Refer to EM-87, "INSTALLATION" .
