Bl COMPRESSION
COMPRESSION
If the engine exhibits low power, poor fuel economy, or poor idle, check the following:
1. Ignition system (Refer to Section G.)
2. Compression
3. Fuel system (Refer to Section F.)
23UOBl-01
23UOBl-06
23UOBl-014 23UOBl-012
INSPECTION
1. Check that the battery is fully charged. Recharge it if neces-
sary. (Refer to Section G.)
2. Warm up the engine to normal operating temperature.
3. Turn the engine OFF.
4. Remove all spark plugs.
5. Disconnect the ignition coil connector.
6. Connect a compression gauge to the No. 1 spark plug hole.
7. Fully depress the accelerator pedal and crank the engine.
8. Record the maximum gauge reading.
9. Check each cylinder.
Compression kPa (kg/cm*, psi)-rpm
10. If the compression in one or more cylinders is low, pour a
small amount of engine oil into the cylinder and recheck
the compression.
(1) If the compression increases, the piston, piston rings,
or cylinder wall may be worn.
(2) If the compression stays low, the valve may be stuck
or seating improperly.
(3) If the compression in adjacent cylinders stays low, the
cylinder head gasket may be defective or the cylinder
head distorted.
11. Connect the ignition coil connector.
12. Install the spark plugs.

Steps After Installation
1. Connect the negative battery cable.
2. Start the engine and check as follows:
l Ignition timing. (Refer to page B2-8.) 10. Loosen the tensioner lock bolt to apply spring tension to
the timing belt.
11. Tighten the tensioner lock bolt.
Tightening torque:

12. Install the pulley boss and pulley lock bolt.
13. Turn the crankshaft 2 and 116 turns clockwise and verify
that the timing marks are correctly aligned.
14. Measure the timing belt deflection by applying moderate
pressure (98 N,
10 kg, 22 lb) midway between the cam-
shaft pulleys.
If the deflection is not correct, repeat from Step 10 above.
Deflection:
9.0-11.5mm (0.35-0.45 In) at 98 N (10 kg, 22 lb)
Spark plug
1. Install the spark plugs.
