REMOVAL
1.
Using a screwdriver, remove the distributor cap and position it and the attached wires aside so as not to interfere with work area.
2.
Remove distributor from engine block.
3.
Remove rotor.
4.
Remove drive coupling spring with small screwdriver or ice pick. Take care not to damage drive coupling or spring.
5. a.
Using an air hose, blow dirt and oil from the drive end of the distributor.
b.
Put a small paint dot on the drive coupling and the shaft to note orientation for re-assembly.
c.
Place the distributor support tool in a vise and tighten or open vise jaws enough to support drive coupling, yet let pin drop out of the
coupling.
d.
Line-up the drive pin with the slot in the base.
6.
With someone holding the distributor steady on the support tool or vise, use a 1/8" dia. drift and hammer to drive the pin out of the shaft.
7.
Remove the distributor from the fixture. Remove the drive coupling from the fixture and place aside for re-assembly.
8.
After assuring there are no burrs, remove shaft assembly by gently pulling up on the shaft plate.
9.
Check shaft assembly for free movement of the centrifugal advance mechanism by holding shaft in hand and moving shaft plate. Shaft plate
assembly should advance freely and spring back to original position when released. If binding occurs, replace complete distributor.
10.
Remove the two screws on the connector hold-down plate on the side of the distributor. (Retain the screws for re-assembly.)
11.
Remove the connector hold-down plate.
12.
Remove the diaphragm assembly.
13.
Remove the three screws that secure the stator retainer to the base.
14.
Lift the stator assembly out of the base by gently lifting up.
15.
Thread connector through hole in the base to complete stator assembly removal.
16.
Disassemble stator retainer assembly from stator assembly by pulling the retainer assembly from the stator assembly.
17.
Inspect the stator bumper for excess wear or signs of excess heat concentration, replace complete distributor assembly if bushing is damaged.
18.
Inspect diaphragm "O" ring for cracks or tears, and replace if needed.
19.
Inspect base bushing for wear or signs of excess heat concentration, replace complete distributor assembly if bushing is damaged.
20.
Inspect shaft oil seal for tears or cuts, replace complete distributor assembly if oil seal is damaged.
21.
Carefully check the spring retainer that holds the shaft oil seal against the shaft. It must be present and have no kinks or breaks. Replace spring if
necessary.
22.
Inspect base "O" ring for cuts or damage and replace "O" ring if necessary.
23.
Inspect base casting for cracks and wear. Replace complete distributor assembly, if damage is found.

RE-ASSEMBLY AND INSTALLATION
1.
Assemble stator retainer assembly to the stator assembly by sliding the stator bumper into the groove in the bottom of the stator with the horseshoe
opening at the diaphragm rod pivot pin.
2.
Make sure the metal base bushing spacer is present and properly seated on the top of the base bushing.
NOTE: Metal spacer was eliminated approximately mid-year and may not be present.
3.
Thread the connector through the large opening in the side of the base.
4.
Place the stator assembly over the base bushing with the diaphragm pivot pin approximately in front of the diaphragm mounting hole.
5.
Using a small screwdriver or punch, line up the holes in the stator retainer plate with the holes in the base.
6.
Install the three retaining screws in the base to specification. The screw, clockwise from the diaphragm mounting hole, is to have the ground
eyelet from the connector mounted under it.
7.
Check stator assembly for free rotation. If stator does not rotate freely, disassemble and check parts.
8.
Assemble connector hold-down plate to connector by placing the tab on the connector into the slot in the connector hold-down plate.
9.
Place connector and hold-down plate against side of the base, locating connector in groove, and line up holes in the hold-down plate with the holes
in the base.
10.
Check the wires from the connector to insure that the wires are not pinched between the base and the connector hold-down plate.
11.
Install the two screws to secure the connector hold-down plate to the base to specification.
12.
Install the diaphragm assembly.
13.
Apply a light coat of M2C162A oil to the distributor shaft below the armature.
NOTE: Do not over-lubricate.
14.
Insert the shaft assembly through the base bushing.
15.
Place drive coupling over shaft and line up paint dots that were made during dis-assembly. Start pin into drive coupling and shaft.
