6. Face the SST (body) outside of the cylinder head,
and mount it on the SST (shaft) at the point of the
adjustment shim to be replaced.
7. Face the notch of the tappet so that a fine
screwdriver can be inserted.
8. Set the SST on the tappet by its notch.
9. Tighten bolt B to secure the SST (body).
Caution
••••
Cylinder head can be damaged when the
tappet is pressed down.
10. Tighten bolt C, and press down the tappet.
11. Using a fine screwdriver, pry up the adjustment
shim through the notch on the tappet. Remove
the shim using a magnet.
12. Select proper adjustment shim.
New adjustment shim
= Removed shim thickness + Measured
valve clearance - Standard valve clearance
(0.26 mm {0.010 in})
13. Push the selected shim into the tappet.
14. Loosen bolt C to allow the tappet to move up.
15. Loosen bolt B and remove the SST (body).
16. Remove the SSTs and tighten the camshaft cap
bolts.
Tightening torque
11.3—14.2 N·m {115—145 kgf·cm, 100—125 in·lbf}
17. Verify the valve clearance. (See 01–10B–5 VALVE CLEARANCE INSPECTION [FS].)

COMPRESSION INSPECTION [FS]
A3U011002000W01
Warning
••••
Hot engines and oil can cause severe burns. Be careful not to burn yourself during removal/
installation of each component.
1. Verify that the battery is fully charged.
•
Recharge it if necessary. (See 01–17–1 BATTERY INSPECTION.)
2. Warm up the engine to the normal operating temperature.
3. Stop the engine and allow it to cool off for about 10 min.
4. Perform “Fuel Line Safety Procedures”. Leave the fuel pump relay removed. (See 01–14–4 BEFORE REPAIR
PROCEDURE.)
5. Remove the ignition coils. (See 01–18–1 IGNITION COIL REMOVAL/INSTALLATION.)
6. Remove the spark plugs.
7. Connect a compression gauge into the No.1 spark plug hole.
8. Fully depress the accelerator pedal and crank the engine.
9. Note the maximum gauge reading.
10. Inspect each cylinder as above.
•
If the compression in one or more cylinders is low or the compression difference between cylinders
exceeds the maximum, pour a small amount of clean engine oil into the cylinder and recheck the
compression.
— If the compression increases, the piston, the piston rings, or cylinder wall may be worn and overhaul is
required.
— If the compression stays low, a valve may be stuck or improperly seated and overhaul is required.
— If the compression in adjacent cylinders stays low, the cylinder head gasket may be damaged or the
cylinder head distorted and overhaul is required.
Compression
kPa {kgf/cm
2
, psi} [rpm]
1. Disconnect the compression gauge.
2. Install the spark plugs.
Tightening torque
15—22 N·m {1.5—2.3 kgf·m, 11—16 ft·lbf}
3. Connect the ignition coil connector.
4. Install the fuel pump relay.

TIMING BELT REMOVAL/INSTALLATION [FS]
A3U011012040W01
1. Disconnect the negative battery cable.
2. Remove the CMP sensor and CKP sensor. (See 01–40B–34 CAMSHAFT POSITION (CMP) SENSOR
REMOVAL/INSTALLATION [FS].) (See 01–40B–34 CRANKSHAFT POSITION (CKP) SENSOR REMOVAL/
INSTALLATION [FS].)
3. Remove the ignition coils. (See 01–18–1 IGNITION COIL REMOVAL/INSTALLATION.)
4. Remove the spark plug.
5. Remove in the order indicated in the table.
6. Install in the reverse order of removal.
7. Inspect the air gap. (See 01–40B–32 Air Gap Inspection.)
8. Adjust the drive belt deflection/tension. (See 01–10B–4 DRIVE BELT ADJUSTMENT [FS].)
9. Start the engine and:
(1) Inspect the pulleys and drive belt for runout and contact.
(2) Inspect the ignition timing. (See 01–10B–25 Ignition Timing Inspection.)
