#### SIGNAL GENERATOR AIR GAP INSPECTION

NOTE: The air gap in the distributor should be check periodically. Distributor air gap may only be checked and can only be adjusted by component replacement.

Remove the hold-down bolts from the top of the distributor cap.

1. Remove the distributor cap from the housing without disconnecting the ignition wires.
2. Pull the ignition rotor (not the signal rotor) straight up and remove it. If the contacts are worn, pitted or burnt, replace it. Do not file the contacts.
3. Turn the crankshaft (a socket wrench on the front pulley bolt may be used to do this) until a tooth on the signal rotor aligns with the projection of the pick-up coil. s0>Using a non-ferrous feeler gauge (brass, copper or plastic) measure the gap between the signal rotor and the pick-up coil projection. DO NOT USE AND ORDINARY METAL FEELER GAUGE! The gauge should just touch either side of the gap (snug fit). The acceptable range for the air gap is as follows:
   - 1991–92 models — 0.008–0.016 inch (0.20–0.40mm)
   - 1993–97 models — 0.008–0.020 inch (0.20–0.50mm)

4. If the air gap is not within specifications, replace the IIA distributor housing.
5. Check to make sure the housing gasket is in position on the housing.
6. Install the rotor.
7. Install the distributor cap with attached wiring. Attach the cap to the housing and tighten the hold-down bolts.
