Service manual
11.2. Adjusting the air gap and checking the coil
1 - Remove the starter assembly
.
2 - Make sure that the earth cable faston (
6
) of the
coil (
7
) is not oxidized; if it is, disconnect, clean and
remount it, spraying it with a special antioxidant.
3 - Check that the coil earth cable is intact. The
black spark plug cable (
8
) should not have any
cracks or signs of deterioration or burns which re-
duce its efficiency and insulation level.
4 - Slack off the screw (
9
) and the stud (
10
) which
secure the coil (
7
).
At the bottom of the machine to which the engine
is fitted, release the safety brake.
Rotate the fan (
11
) so as to bring the magnetic
inserts next to the poles of the core of the coil.
5 - Insert a 0.35 mm thickness gauge (
12
) between
the complete fan (
11
) and the coil poles (
7
), push
the coil until the poles come in contact with the
thickness gauge and secure screw (
9
) and stud
(
10); with the flywheel locked, the airgap must be
between 0.35 and 0.45 mm.
NOTE: An accurate inspection of the effi-
ciency of a coil can only be carried out in a
laboratory equipped with a oscilloscope.
To make a brief check, proceed as follows:
6 - Disconnect the earth cable faston (
6
) of the
coi (
7
).
