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 t he 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.

CAMSHAFT
• 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-11, "
Fluids and Lubricants".
• Use procedure below to check for fuel leaks.
• Turn ignition switch ON (with engine stopped). With fuel pressure applied to fuel piping, check for fuel leaks
at connection points.
• Start engine. With engine speed increased, che ck again for fuel leaks 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 leak s 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.

INSPECTION AFTER REMOVAL
Oil Filter
• 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 differe nt diameter from the other
four locations.
2. Set a suitable tool vertically to No. 3 journal.
3. Turn camshaft to one direction, and measure the camshaft runout using suitable tool. (Total indicator reading)

CAMSHAFT
1. Install camshaft in cylinder head. Refer to
EM-60, "Removal and Installation" for tightening procedure.
2. Install a suitable tool (A) in thrust direction on front end of cam- shaft. Measure the camshaft end play using suitable tool when
camshaft is moved forward/backward (in direction of axis).
• Measure the following parts if out of the standard.
- Dimension “A” for cylinder head No. 1 journal bearing
- Dimension “B” for camshaft thrust
• Refer to the standards above, and then replace camshaft and/
or cylinder head.
Camshaft Sprocket Runout
1. Put V-block on precise flat table, and support No. 2 and 5 journals of camshaft. CAUTION:
Do not support No. 1 journal (on the side of cam shaft sprocket) because it has a different diameter
from the other four locations.
2. Measure the camshaft sprocket runout using suitable tool (A). (Total indicator reading)
• If it exceeds the limit, replace camshaft sprocket.
Valve Lifter
Check if surface of valve lifter has any wear or cracks.
• If anything above is found, replace valve lifter. Refer to EM-117,
