is pressed against the rotor. Apply the pressure to the contact button to avoid setting the spring. Clean the button so that
it makes a good contact on the carbon contact in the center of the cap.
c. Ignition Coil. Never dip-clean, or steam-clean the ignition coil since this causes injury to the windings and
insulation, and produces early failure. Clean by wiping with a clean, dry cloth. Inspect the terminals for stripped, or
crossed threads. Check coil head for cracks, chipped places, or burned paths that would allow high tension leakage to
ground. Note the condition of the coil case, making sure that it is not punctured, or that the seams have not opened up.
Test the coil on a coil tester. Replace the coil if it is damaged mechanically, or electrically in any way.
d. Breaker Plate.
(1) Remove the clamp screw (22), plain washers (20) lockwashers (21), and spring clip (19). Take off the
primary lead assembly (33). Remove the fillister head screw (34), and lift the contact from the plate. Take
out the capacitor mounting screw (17), and lift out the capacitor (18).
(2) Clean all parts with a cloth dampened in a cleaning solvent.
(3) Rub contacts with linen tape that has been dampened in carbon tetrachloride. Dry with clean tape to
remove any residue.
(4) Test capacitor for capacity and grounds on a tester. Replace the capacitor if grounded, leaky, or if the
capacity is not between 0.18 to 0.21 microfarads. Inspect the lead and replace condenser if the lead or
terminal is chafed, partially broken, or damaged.
(5) Inspect the plate for stripped threads, and damaged or worn pivot pin. Replace the plate if any of these
conditions are found. Check the primary terminal for grounds with a test light and test probes. Replace the
plate if the primary terminal is grounded.
(6) Inspect the breaker contact set (23). If the contacts are a grayish color and are not pitted or burned, they
need not be replaced. Replace the breaker contact set if the contacts are rough, burned, or pitted.
(7) Install' the contacts on the plate and turn the distributor lever on the pivot. It must turn easily without binding
or looseness. Remove the lever and inspect the pivot. Replace the plate if wear is evident on the pivot, or if
the pivot is loose or not perpendicular to the plate. If the pivot is in good condition, install a new breaker
