Stator Assembly

Tools Required:

• Axle Bearing/Seal Plate T75L-1165-B
• Pinion Bearing Cone Remover D79L-4621-A

Removal

 CAUTION: Do not attempt to replace stator without an arbor press.

1. Using a screwdriver, remove distributor cap, position the cap and wires aside so as not to interfere with work area. Disconnect distributor from harness.

2. Remove distributor from block as outlined.

3. Remove rotor.

4. Remove two screws holding ICM to the base, if so equipped.

5. Remove ICM, wipe grease from base and ICM, keeping surfaces free of dirt, if so equipped.

   NOTE: Hold gear to loosen armature screws. Do not hold armature.

6. Remove two screws holding armature and remove armature.

7. To ease assembly, mark armature collar and gear with a felt tip pen, to note orientation.

8. Remove and discard pin in gear and in collar.

9. Invert distributor and place in Axle Bearing/Seal Plate T75L-1165-B and press off gear using the Pinion Bearing Cone Remover D79L-4621-A or equivalent.
   
   
   
   

10. Remove armature.

11. Deburr and polish shaft with emery paper and wipe such that shaft slides out freely from distributor base.

12. Remove shaft assembly.

13. Remove two stator assembly screws and retain.

14. Remove stator assembly from top of bowl.

15. Remove octane rod retaining screw and octane rod.

16. Inspect base bushing for wear or signs of excess heat concentration. Replace complete distributor assembly if damaged.

17. Inspect base O-ring for cuts or damage and replace O-ring if necessary.

18. Inspect base for cracks and wear. Replace complete distributor assembly if damage is found.

Installation

1. Place stator assembly over bushing and press down to seat.

2. Place stator connector in position. Tab should fit in notch on base and fastening eyelets aligned with screw holes.

3. Position wires away from moving parts.

4. Install two stator screws and tighten to 1.7-4.0 Nm (15-35 lb-in).

5. Install octane rod and retaining screw. Tighten to 1.7-4.0 Nm (15-35 lb-in).

6. Apply a light coat of Motor Oil XO-10W30-QSP (ESE-M2C153-E) or equivalent, to distributor shaft below armature.

7. Insert shaft through base bushing.

8. Install collar and new roll pin.

9. Place a 1/2-inch deep well socket over shaft, invert and place on arbor plate.
   
   
   
   

10. Place the distributor gear on shaft end. Line up the mark on armature and gear.

    NOTE: The hole in the shaft and gear must be lined up as accurately as possible to ensure ease of roll pin insertion.

11. Place a 5/8-inch deep well socket over the shaft and gear and press gear to align with original drill hole.

    NOTE: If the gear holes do not align, the gear must be removed and repressed on. A drift punch will not align the holes.

     CAUTION: If gear is damaged, do not replace gear, serious engine damage may result. Replace complete distributor assembly.

    
    
    
    
    

12. Insert new roll pin through gear and shaft. Pin should have proper extrusion.

13. Replace armature and tighten screws to 2.8-4.0 Nm (25-35 lb-in).

    NOTE: If the armature contacts the stator, replace the entire distributor.

14. Check distributor for free movement over full rotation of shaft.

15. Wipe back of ICM and distributor module mounting face free of all dirt, if so equipped.

16. Apply Silicone Dielectric Compound WA-10, D7AZ-19A331-A (ESE-M1C171-A) or equivalent to the back of the ICM and spread thinly and evenly, if so equipped.

17. Turn distributor base upside down so that the stator connector is in full view.

18. Insert ICM and watch that the three module pins are inserted into the stator connector. Fully seat the ICM into the connector and against base.

19. Install two ICM screws and tighten to 1.7-4.0 Nm (15-35 lb-in), if so equipped.

20. Install the distributor into block per distributor replacement procedure.

21. Connect distributor module to wiring harness.

22. Replace rotor.

23. Replace cap and tighten screws to 2.0-2.6 Nm (18-23 lb-in).

24. Set engine timing.
