INSPECTION
Perform inspection as follows after removal, replacement or installation of camshaft or valve-related parts, or if
there are unusual engine conditions regarding valve clearance.
1. Remove rocker cover. Refer to
EM-48, "
Removal and Installation".
2. Measure the valve clearance with the following procedure:
a. Set No. 1 cylinder at TDC of its compression stroke. • Rotate crankshaft pulley (2) clockwise and align TDC mark (no
paint) (A) to timing indicator (1) on front cover.
• At the same time, check that both intake and exhaust cam lobes of No. 1 cylinder face inside ( ) as shown.
• If the lobes do not face inside, rotate the crankshaft pulley 360 degrees to align as shown.
b. Using suitable tool (A) measure the clearance between the valve lifter and camshaft.

3. Measure the center thickness of the removed valve lifters using
a suitable tool (A).
4. Use the equation below to calculate valve lifter thickness for replacement.
• Crown surface thickness of new valve lifter (B) can be identi-fied by stamp mark (A) on the under side of the lifter.
NOTE:
Available thickness of valve lifter: 26 sizes range 3.00 to 3.50
mm (0.1181 to 0.1378 in) in increments of 0.02 mm (0.0008 in)
when manufactured at factory. Refer to EM-117, "
Camshaft".
• Stamp mark “302” indicates 3.02 mm (0.1189 in) in thickness.
5. Install the correct thickness valve lifter.
6. Install camshaft. Refer to EM-60, "
Exploded View".
7. Install timing chain. Refer to EM-51, "
Exploded View".
8. Manually rotate crankshaft pulley a few rotations.
9. Check that valve clearances are within specification. Refer to “INSPECTION”.
10. Installation of remaining components is in the reverse order of removal.
11. Warm up the engine, and check for unusual noise and vibration.

COMPRESSION PRESSURE
InspectionINFOID:0000000012431691
1. Warm up engine to full operating temperature and then turn it off.
2. Release fuel pressure. Refer to
EC-137, "
Work Procedure".
3. Remove ignition coil and spark plug from each cylinder. Refer to EM-48, "
Exploded View".
4. Connect engine tachometer (not required in use of CONSULT).
5. Install compression gauge (B) with an adapter (A) into spark plug hole.
• Use an adapter with a diameter (a) smaller than 20 mm (0.79in). Otherwise, it may be caught by cylinder head during
removal.
6. With accelerator pedal fully depressed, turn ignition switch to »»» for cranking. When the gauge pointer stabilizes, read the compression pressure and the engi ne rpm. Perform these steps to check each cylin-
der.
CAUTION:
Always use a fully charged battery to obtain the specified engine speed.
• If the engine speed is out of the specified range, check the battery. Check the engine speed again with a
fully charged battery.
• If some cylinders have low compression pressure, pour a small amount of engine oil into the spark plug hole to recheck the compression.
- If the added engine oil improves the compression, the piston rings may be worn or damaged. Check the piston rings and replace if necessary.
- If the compression pressure remains low despite the addition of engine oil, the valves may be malfunc-
tioning. Check the valves for damage. Replace the valve or valve seat as necessary.
• If two adjacent cylinders have respectively low compression pressure and their compression remains low even after the addition of engine oil the head gasket may be leaking, or valves in adjacent cylinders
may be damaged. Inspect and repair as required.
• If the compression pressure is below the minimum value, check the valve clearances and parts associ-
ated with the combustion chamber (valve, valve seat , piston, piston ring, cylinder bore, cylinder head,
cylinder head gasket). After repairing, measure the compression pressure again.
7. After inspection is completed, install removed parts.
8. Start the engine, and ensure that the engine runs smoothly.
9. Perform trouble diagnosis. If DTC appears, erase it. Refer to EC-120, "
Work Flow".

REMOVAL
1. Remove engine undercover. Refer to
EXT-39, "FRONT UNDER COVER : Removal and Installation".
2. Remove wheel and tire (RH) using a power tool. Refer to WT-48, "
Removal and Installation".
3. Partially remove the fender protector (RH). Refer to EXT-38, "
Removal and Installation".
4. Loosen the lock nut and then release the belt tension by turning the adjusting bolt.
5. Remove the drive belt.
INSTALLATION
1. Pull the idler pulley in the loosening direction, and then temporarily tighten the lock nut to the following
torque.
NOTE:
Do not move the lock nut from the te mporary tightened position. Go to step 2.
2. Install the drive belt on each pulley. CAUTION:
• Check that there is no engine oil, grease, or engine coolant, etc. in pulley grooves.
• Check that the belt seats securely inside the groove on each pulley.
3. Adjust drive belt tension by turning the adjusting bolt. Refer to EM-17, "
Adjustment".
CAUTION:
• Perform the belt tension adjustment with the lock nut temporarily tightened to the torque specifi-
cation listed in step 1 which preven ts the idler pulley from tilting.
• When checking immediately after in stallation, first adjust it to the specified value. Then, after
turning crankshaft two turns or more, readjust to the specified value to avoid variation in deflec-
tion between pulleys.

4. Tighten the lock nut to final tightening specification.
5. Check that belt tension is within the specification using suitable tool. Refer to

InspectionINFOID:0000000012431695
• Inspection should be done only when engine is cold or over 30
minutes after the engine is stopped.
• Visually check belt for wear, damage, and cracks on inside and edges.
• Turn crankshaft pulley clockwise twice, and check that the tension on all pulleys equalizes before testing.
• When measuring deflection, apply 98.1 N (10 kg, 22 lb) at the ( ) marked point.
• Measure the belt tension and frequency using suitable tool at the ( ) marked point.
CAUTION:
• When checking immediately after installation, first ad just it to the specified value. Then, after turning
crankshaft two turns or more, readjust to the specified value to avoid varia tion in deflection between
pulleys.
AdjustmentINFOID:0000000012431696
CAUTION:
• When belt is replaced with new one, adjust belt te nsion to the value for “New belt,” because new belt
will not fully seat in the pulley groove.
• When tension of the belt being used exceeds “Limit,” adjust it to the value for “After adjusted.”
• When installing a belt, check it is correctly engaged with the pulley groove.
• Do not allow engine oil or engine coolant to get on the belt.
• Do not twist or bend the belt strongly.
1. Partially remove the fender protector (RH) front side clip. Refer to EXT-38, "
Removal and Installation".
2. Loosen lock nut (A) and temporarily set to the following torque.
3. Adjust the belt tension by turning the adjusting bolt. Refer to EM-116, "
Drive Belt".

• When checking immediately after in
stallation, first adjust it to the specified value. Then, after
turning crankshaft two turns or more, readjust to the specified value to avoid variation in deflec-
tion between pulleys.
• When the tension adjustment is performed, the lock nut should be in the condition at Step 2. If the tension adjustment is performed when the lock nut is loosened more than the temporary
tightening, the idler pulley tilts and the corr ect tension adjustment cannot be performed.
4. Tighten the lock nut to final tightening specification.
