7. Install camshaft brackets (No. 2 to 5) aligning the identification

marks on upper surface as shown.

• Install so that identification mark can be correctly read when

viewed from the INT side.

8. Tighten bolts of camshaft brackets in the following steps, in

numerical order as shown.

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.

9. Install the camshaft sprocket (INT and EXH) to the camshaft (INT and EXH):
a. Refer to the matching mark (A) added in step 4. Securely align

the knock pin and the pin hole, and then install them.

NOTE:

The intake side is shown as an example.

10. Tighten the camshaft sprocket bolt (INT and EXH).

CAUTION:

Hold the camshaft hexagonal part (A), using a suitable tool

to secure the camshaft.

CAMSHAFT

11. Install the camshaft (INT and EXH) to the camshaft sprocket

(INT and EXH) (2 and 3) while aligning the matching mark

(marked when timing chain is removed) (A) and the pink link (B)

of camshaft sprocket (INT and EXH).

• If the positions of knock pin and pin groove are not aligned,

move the camshaft (EXH) slightly to correct these positions.

12. Pull out the stopper pin (A), and then apply the tension to the

timing chain by rotating the crankshaft pulley clockwise slightly.

13. Pull out the stopper pin of chain tensioner.
14. Install front cover.
15. Return the camshaft sprocket (INT) in the most retarded position:
a. Remove the stopper pin (A) from the camshaft sprocket (INT).

b. Turn the crankshaft pulley (1) slowly clockwise (A) and return

the camshaft sprocket (INT) to the most retarded angle position.

• When first turning the crankshaft, the camshaft sprocket (INT)

will turn. Once it is turned more, and the vane (camshaft) also

turns, then it has reached the most retarded angle position.

• The most retarded angle position can be checked by seeing if

the stopper pin groove (A) is shifted clockwise.

• After spinning the crankshaft slightly in the counterclockwise

direction, you can check the lock pin has joined by seeing if

the vane (camshaft) and the sprocket move together.

16. Install the camshaft position sensor (PHASE) to the rear end of cylinder head.

• Tighten bolts with it completely inserted.

17. Check and adjust valve clearance. Refer to

EM-10, "Inspection and Adjustment"

18. Installation of the remaining components is in the reverse order of removal.

INSPECTION AFTER INSTALLATION

• Before starting engine, check oil/fluid levels, including engine coolant and engine oil. If less than required

quantity, fill to the specified level. Refer to

MA-12, "Fluids and Lubricants"

• Use procedure below to check for fuel leakage.

• Turn ignition switch ON (with engine stopped). With fuel pressure applied to fuel piping, check for fuel leak-

age at connection points.

• Start engine. With engine speed increased, check again for fuel leakage at connection points.

• Run engine to check for unusual noise and vibration.

NOTE:

If hydraulic pressure inside timing chain tensioner drops after removal and installation, slack in the guide

may generate a pounding noise during and just after engine start. However, this is normal. Noise will stop

after hydraulic pressure rises.

• Warm up engine thoroughly to make sure there is no leakage of fuel, exhaust gas, or any oils/fluids including

engine oil and engine coolant.

• Bleed air from passages in lines and hoses, such as in cooling system.

• After cooling down engine, again check oil/fluid levels including engine oil and engine coolant. Refill to spec-

ified level, if necessary.

• Summary of the inspection items:

*Power steering fluid, brake fluid, etc.

• Check that there is no foreign material on the oil filter (1) and check

it for clogging.

• Check the oil filter for damage.

• If there is some damage, replace the oil filter, the plug, and the

washer as a set.

CAUTION:

Do not reuse the washer.

Camshaft Runout

1. Put V-block on a precise flat table, and support No. 2 and 5 jour-

nals 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 a dial indicator vertically to No. 3 journal.
3. Turn camshaft to one direction, and measure the camshaft

runout on the dial indicator. (Total indicator reading)

4. If it exceeds the limit, replace camshaft.

Camshaft Cam Height

1. Measure the camshaft cam height with a micrometer (A).

2. If wear exceeds the limit, replace camshaft.
