Distributor: Service and Repair

PROCEDURE

Removal

1. Disconnect negative terminal cable from battery.
2. Disconnect distributor connector.
3. Remove distributor cap without disconnecting high-tension cords.
4. Set no. 1 cylinder to TDC/compression.





- Turn the crankshaft pulley until the timing mark is aligned with 0°, mark on the timing chain cover.





- Check that the distributor rotor direction is as shown. If not, turn the crankshaft pulley one complete revolution.
5. Remove distributor.





- Remove the hold-down bolt and pull out the distributor.
- Remove the 0-ring from the distributor housing.

Installation

1. Check no.1 cylinder to TDC/compression. If necessary, remove the cylinder head cover, and check the following conditions:





- Turn the crankshaft pulley and align its groove with the timing mark 0°, of the timing chain cover.





- Verify that the timing marks with 1 and 2 dots are in straight line on the cylinder head surface as shown in the illustration.
- If not, turn the crankshaft 1 revolution (360°) and align the mark as above.
2. Install distributor.





- Install a new 0-ring to the distributor.

HINT: Always use a new 0-ring when installing the distributor.





- Align the groove of the distributor housing with the protrusion on the driven gear.
- Apply a light coat of engine oil on the 0-ring.





- Insert the distributor, aligning the center of the flange with that of the bolt hole on the cylinder head.
- Lightly tighten the hold-down bolt.





3. Install distributor cap.
4. Connect distributor connector.
5. Connect negative terminal cable to battery.
6. Allow the engine to warm up to normal operating temperature.
7. Connect tachometer and timing light.





- Connect the test probe of a tachometer to terminal IG- of the DLC1.

NOTE: NEVER allow the tachometer terminal to touch ground as it could result in damage to the igniter and/or ignition coil. As some tachometers are not compatible with this ignition system, we recommend that you confirm the compatibility of your unit before use.

8. Adjust ignition timing.





- Using jumper connect terminals TE1 and E1 of the DLC1.





- Using a timing light, check the ignition timing.

Ignition timing: 30 BTDC @ idle (Transmission in neutral position and A/C OFF)





- Loosen the hold-down bolt, and adjust by turning the distributor.
- Tighten the hold-down bolt, and recheck the ignition timing.

Torque: 18 Nm (13 ft lb)





- Remove jumper from the DLC1.





9. Further check ignition timing.

Ignition timing: 2 - 13° BTDC @ idle (Transmission in neutral position and A/C OFF)

HINT: The timing mark moves in a range between 2° and 13°.

10. Disconnect tachometer and timing light from engine.
