BREAKER POINT RENEWAL
1. Remove distributor cap and rotor.
2. Remove hairpin clip at (F), Figure 6, screws (0)
attaching vacuum control unit to distributor
housing and remove vacuum control unit.
3. Remove the two screws at (C) and the two nuts,
washers and insulators at (H).
4. Disconnect breaker point wires at (E) and
(Id) and remove complete contact support
plate and contacts with condenser attached
for bench disassembly.
5. Re move screw and clip (A) attaching breaker arm
spring and remove breaker arm spring.
6. Remove lock screw (B) attaching stationary con-
tact and remove the contact.
7. Install a new breaker arm and attach primary and
condenser lead wires to breaker spring clip and
install clip and screw (A).
8. Install a new stationary contact but do not tighten
lock screw; connect wires at (E) and (H) and
install condenser.
9. Install complete contact support plate and
stationary contact as an assembly and in-
stall screws (C) and terminal nuts (H).
10. Check alignment of contact points. Bend the
stationary contact arm if necessary to secure
proper alignment and contact. DO NOT bend
breaker arm.
11. Tighten screw (D) and adjust breaker point gap.
12. Check breaker arm spring tension. Hook a spring
scale to the arm at the contact and pull at a right
angle to the contact surface. T e n s i on should
be 17 to 20 ounces just as the contact separate.
13. Adjust spring tension by loosening screw at (A),
attaching breaker arm spring to plate, and move
end of spring in or out of clip as necessary.
CONDENSER
Check condenser lead to see that it is not frayed
or broken and is connected securely to breaker arm
clip. Condenser mounting screw must make tight
ground to breaker plate. Ground wire from breaker
plate to subplate must be securely connected.
Check condenser with suitable equipment and
if capacity is not within range of .21 to .25 MFD,
replace with new parts.
DISTRIBUTOR REMOVAL
1. Remove wires from distributor cap and remove
cap.
2. Disconnect vacuum line and the distributor primary
wire.
3. Re move the lock plate and the hold down
screw attaching distributor quadrant to engine
and remove distributor from engine.

retainer from oil well and pull cam off shaft.
3. Remove centrifugal weights and springs, using
care to prevent distortion of springs.
4. Drive out pin from distributor shaft collar and
remove shaft through top of distributor.
ASSEMBLY
1. If clearance between shaft and bushings is
greater than .005", install new shaft and bush-
ings. Soak bushing in engine oil for 15 minutes
before installing shaft.
2. Install distributor shaft, thrust washers, collar
and pin. Peen over pin.
3. Check distributor shaft end play for minimum of
