Removal
Do not attempt to replace stator without an arbor press.
1.
Remove distributor. Remove rotor, then the TFI module.
2.
If distributor uses push on type rotor, remove two retaining screws holding armature, then the armature. Hold gear to loosen armature
screws, do not hold armature.
3.
Mark stator, armature, gear and collar with felt tip pen to aid in reassembly.
4.
Remove and discard pins in gear and collar if equipped.
5.
Invert distributor and place in Axle Bearing Seal Plate and press off gear using Bearing Removal Tool.
6.
Deburr and polish shaft with emery paper and wipe clean so that shaft slides out freely from distributor base.
7.
Remove shaft assembly, then the thrust washer from shaft. Next remove octane rod.
8.
Remove stator assembly screws, then the stator assembly from top of bowl.
9.
Inspect base bushing for wear of signs of excess heat concentration, replace distributor assembly if damaged.
10.
Inspect base O-ring for cuts or damage and replace as necessary.
11.
Inspect base for cracks and wear, replace 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 with fastening eyelets aligned with screw holes.
3.
Install stator screws and Torque to 15-35 inch lbs. Next install octane rod.
4.
Install thrust washer on top of bushing, then apply lubricant to distributor shaft below armature. Do not over lubricate.
5.
Insert shaft through base bushing, then place collar, if equipped, over shaft and line up mark on armature and collar to aid alignment with
original drill hole. Use a suitable drift punch to assure proper alignment.
6.
Drill holes through shaft and collar should align on both sides of shaft. If holes do not align, collar may be 180 degrees out of alignment on
shaft. Rotate collar on shaft one half rotation, then check.
7.
