19. Check capacitors for looseness in the magneto cover of the harness assembly and for any physical
damage. The capacitors should be checked for capacitance, series resistance and leakage. Capacitance
should be 0.34 to 0.41 microfarads. The use of a Bendix condenser tester, part number 11-1767-1, -2
or -3 or equivalent will simplify this test. Replace defective capacitors and torque securing nut to 60-
70 inch-pounds.
– NOTE –
Spring in capacitor outlet may cause an indication of a short
to ground if adapter lead is not used. (Refer to Figure 4.)
IMPULSE COUPLING REMOVAL.
1. Using heavy gloves or shop cloth, grasp the coupling body firmly to prevent the internal spring from
unwinding suddenly. Pull outward on the coupling body only enough to release it from the cam assem-
bly. Keep the coupling body close against the cam and allow the body to turn as the spring unwinds.
After one or two turns, the spring coils will wedge against the projections on the body, restraining the
spring from further unwinding.
2. Look into the hole in body and note the location of the inner eye of spring where it engages with mat-
ing recess in cam hub. Insert a screwdriver under spring end and pry spring eye out of recess. Remove
the body and spring together. Uncoil spring from body and pry spring eye from body recess to disen-
gage spring.
3. Thread protective cap of 11-702-1 puller securely on end of shaft. Engage puller over protective cap
and cam assembly with wide jaws of puller hooked under cam assembly as shown in Figure 10.
4. Tighten puller handle to remove coupling from shaft. If coupling does not release with maximum
hand torque at puller handle, apply penetrating thread release compound between coupling and shaft.
Then while puller is still fully tightened, hold tip of hot heavy duty soldering iron in contact with hub
of coupling cam assembly. Solder wetting of the tip at point of contact with the cam hub will assist in
heat transfer to the parts. Retighten puller after about a minute of heat application.
– CAUTION –
Do not strike the puller with a hammer. If puller is struck with
a hammer the main bearings must be replaced.
5. Do not tighten puller handle further after coupling cam releases from the shaft. This could damage the
flyweight if the flyweight is caught under the woodruff key. Remove the puller from the shaft. Then
while holding both flyweight tips inward, lift cam from the shaft, and remove woodruff key from rotor
shaft.
INSPECTION OF IMPULSE COUPLING.
1. Check clearance between each flyweight and each stop pin by the following method:
a. Bend the end of a stiff piece of wire into a right angle, 1/8 inch long maximum.
b. Hold the magneto as shown in Figure 11. Pull the heel of the flyweight outward with the fabricated
hooked wire and make certain that a feeler gauge of 0.015 of an inch minimum thickness will
pass between the stop pin and the highest point of the flyweight.
