Installation (Engine Rotated After Removal)

  1. Clean distributor mounting area of cylinder block. Install replacement gasket. Remove No. 1 spark plug and hold finger over spark plug hole. Rotate engine until compression pressure is felt. Slowly continue to rotate engine until timing index on vibration damper pulley aligns with TDC mark on timing degree scale.
  2. Using a flat blade screwdriver, rotate oil pump gear so that gear slot on oil pump shaft is slightly past 3 o'clock position. With distributor cap removed, install distributor with rotor located at 5 o'clock position. See Fig 1 .

  3. When distributor is fully engaged in correct location, rotor should be at 6 o'clock position. See Fig 1 . Install distributor hold-down bolt and clamp. Tighten bolt to 17 ft. lbs. (23 N.m).
    CAUTION: If distributor cap is incorrectly positioned on distributor housing, cap or rotor may be damaged when engine is rotated with starter.
  4. Install distributor cap, with ignition wires attached, on distributor housing. Ensure pick-up coil wire rubber grommet in distributor housing aligns with depression in distributor cap and that cap fits on rim of housing.
    NOTE: Two different diameter screws are used to retain distributor cap.
  5. Apply silicone dielectric compound to connector terminal blades and cavities. Connect distributor primary wiring connector.
