2 (a). Ignition Coil
The ignition coil should be kept clean and the
terminals kept tight.
2 (b). Contact Breaker Unit Model CA1A
(See Fig. 5). Lubrication every 3,000 miles.
(i) Remove the metal cover and smear thin oil
on the cam. On no account must oil or grease be
allowed to get on or near the contacts.
(ii) Lubricate the automatic timing control
mechanism using thin machine oil.
Cleaning every 6,000 miles.
Examine the contact breaker. The contacts
must be free from grease and oil. If they are burnt
or blackened, clean with a fine carborundum stone
or a very fine emery cloth. Wipe away any dirt or
metal dust with a clean petrol moistened cloth.
Cleaning of contacts should be carried out with
the moving contact removed. To remove this,
slacken the terminal screw and withdraw the
rocker arm complete with contact and spring.
Before replacing the arm lightly smear the
pivot with grease. When refitting the contact
breaker arm spring make sure that it is below the
fibre washer, i.e. between the fibre washer and the
wiring tag from the condenser.
2 (c). Contact Breaker Setting
The contact breaker setting should be checked
after the first 500 miles running and subsequently
every 6,000 miles. To check the gap, turn the
engine over slowly until the contacts are seen to
be fully open and insert a 0.014-0.016 in. feeler
gauge between the contacts.
If the gap width is correct the gauge will be a
sliding fit. To adjust the setting, set the engine in
the position giving maximum contact opening.
Slacken the two screws securing the contact
carrier plate to the back plate. The contact carrier
plate swivels around the rocker arm pivot and can
be adjusted until the correct gap is obtained.
