DISTRIBUTOR INSPECTION

NOTICE: "Cold" and "Hot" in the following sentences express the temperature of the coils themselves. "Cold" is from 10°C (14°F) to 50°C (122°F) and "Hot"is from 50°C (122°F) to 100°C (212°F).

1. REMOVE DISTRIBUTOR CAP WITHOUT DISCONNECTING HIGH-TENSION CORDS
2. REMOVE ROTOR





3. INSPECT AIR GAP
Using SST (G1 and G2 pickups) and a feeler gauge (NE pickup), measure the air gap between the signal rotor and pickup coil projection. SST 09240-00020 for G1 and G2 pickups

Air gap: 0.2 - 0.5 mm (0.008 - 0.020 in.)

If the air gap is not as specified, replace the distributor housing assembly.
4. DISCONNECT DISTRIBUTOR CONNECTOR

Ohmmeter Connection:

5. INSPECT SIGNAL GENERATOR (PICKUP COIL) RESISTANCE
Using an ohmmeter, measure the resistance between terminals.
If the resistance is not as specified, replace the distributor housing assembly.
6. RECONNECT DISTRIBUTOR CONNECTOR
7. REINSTALL ROTOR
8. REINSTALL DISTRIBUTOR CAP
