MAGNETO COVER
The magneto cover, can be removed by loosening
the four screws which hold. it in place. When replacing
the cover be sure that the cover gasket is in its proper
place.
ftnnneKER coNTACTS - REpLACEMENT AND
ADJUSTMBNT
The breaker contacts should be adiusted to .015"
when fully opened. To adjust the contacts, loosen the
two clamp screws enough so that the contact plate can
be moved.
Insert the end of a small screw driver in the adjust-
ing slot and open or close the contacts by moving the
plate until the opening is .015", measuring with a feeler
gauge of that thichress, tighten the two clamp screws.
" fo replace the contacts reniove the bieaker, the
spring clarnp screw, the breaker arm lock and wisher,
and fhen lifl the breaker arm from its pivot. Remove
the spacing washer and the two breaker plate clamp
screws. The breaker plate can then be removed.
If the contacts need replacing it is recommended
that both the ffxed contact and the breaker arm be re-
placed at the same time, using replacement breaker set.
- After assembly the contacts should be adiusted as
described above. The contacts should be kept clean at
all times. Lacquer thinner is an ideal cleaner for this
purpose.
CONDENSER
To remove the condenser, ffrst disconnect the con-
denser lead by removing the breaker arm spring screw,
then remove the two condenser clamp screws, and the
condenser clamp. When replacing the condenser make
sure it is properly placed and that the clamp screws are
securely tightened.
COIL AND COIL CORE
The coil and coil core must be removed from the
magneto housing as a unit. Disconnect the primary wire
from the breaker arm spring terminal by removing
screw, take out the two coil core clamp screws, and
remove the clamps. The coil and core can then be
pulled from the housing. When replacing this group
make sure that the bare primary wire is connected under
the core clamp screw and that the insulated wire is con-
nected to the breaker arm spring terminal.
REMOVAL OF COIL FROM CORE
The coil is held tight on the core by two wedges. It
will be necessarv to-press against the coil core with
considerable force to rtmove lt from the coil. The coil
should be supoorted in such a way that there is no
danger of the irimary of the coil b6ing pushed out of
the secondarv.
When replacing the coil on the coil core, slide it on
then press in the two coil wedges, one on each end,
until lhey are fush with the primary of the cpil.
