• Secure crankshaft pulley with a suitable tool and tighten crankshaft pulley bolt.
a. Apply new engine oil to thread and seat surfaces of crankshaft pulley bolt.
b. Tighten crankshaft pulley bolt.
c. Put a paint mark (B) on crankshaft pulley, mating with any one of six easy to recognize angle marks (A) on crankshaft bolt flange
(1).
d. Turn another 60 degrees clockwise (angle tightening). • Check the tightening angle with movement of one angle mark.
10. Check that crankshaft turns smoothly by rotating by hand clockwise using suitable tool.
11. Installation of the remaining components is in the reverse order of removal.
INSPECTION AFTER INSTALLATION
• Before starting engine, check oil/fluid levels, includi ng 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, check 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 are no lea ks 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)

c. Disconnect ignition coil and injector harness connectors.
3. Remove intake valve timing control solenoid valve. Refer to
EM-60, "
Exploded View".
4. Crank engine, and then check that engine oil comes out from intake valve timing control solenoid valve hole (A). End crank
after checking.
WARNING:
Be careful not to touch rotating parts (drive belts, idler pul-
ley, and crankshaft pulley, etc.).
CAUTION:
• Prevent splashing by using a shop cloth to prevent injuryfrom splashing engine oil and so as to prevent engine oil contamination.
• Use a shop cloth to prevent engine oil from bein g splashed to engine and vehicle. Especially be
careful not to spill engine oil to rubber parts of drive belts, engine mounting insulator, etc. Wipe
engine oil off immediatel y if it is splashed.
5. Perform the following inspection if engine oil does not come out from intake valve timing control solenoid valve oil hole of the cylinder head.
• Remove oil filter, and then clean it. Refer to LU-10, "
Removal and Installation".
• Clean oil groove between oil strainer and intake valve timing control solenoid valve. Refer to LU-5,
"Engine Lubrication System".
6. Remove components between intake valve timing c ontrol solenoid valve and camshaft sprocket (INT),
and then check each oil groove for clogging.
• Clean oil groove if necessary. Refer to LU-5, "
Engine Lubrication System".
7. After inspection, installation of components is in the reverse order of removal

5. Using a suitable tool finish valve seat to the specified dimen-
sions. For dimensions, refer to MA-11, "
Fluids and Lubricants".
CAUTION:
When using a valve seat cutter, firmly grip the cutter handle
with both hands. Then, pr ess the contacting surface evenly
around the valve seat to cut in a single attempt. Improper
pressure or cutting several times may result in wavy valve
seat.
6. Using compound, grind to adjust valve fitting.
7. Check again for normal contact. Refer to "VALVE SEAT CONTACT".
VALVE SPRING SQUARENESS
• Set a tri-square (A) along the side of valve spring and rotate spring. Measure the maximum clearance between the top of spring and
tri-square.
• If it exceeds the limit, replace valve spring.
VALVE SPRING DIMENSIONS AND VALVE SPRING PRESSURE LOAD
• Check valve spring pressure with valve spring seat installed at the specified spring height.
CAUTION:
Do not remove valve spring seat from valve spring.
• If the installation load or load with valve open is out of the stan- dard, replace valve spring (with valve spring seat).
INSPECTION AFTER INSTALLATION
• Before starting engine, check oil/fluid levels, incl uding 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
