3.18) Trigger coil kit replacement
See Figs. 74-28, 74-29, 74-30, 74-31, 74-32 and 74-33.
Because of the shielding (6), the trigger coil kit (5) can be exchanged only as a
complete set. Remove the attachment screws (7) with the distance sleeves (8)
and cable clamps and fit new trigger coil kit. The stator (9) need not be removed
in this case.
The trigger coils (1) are only adjustable to a limited extent. The gap (2) between
trigger coil and trigger cam (3) is equal to dimension (IH02). The trigger coils
must be centred relative to the trigger cam and any offset must not exceed
dimension (IH03).
◆
NOTE: The trigger coil kit for older engine versions is no longer
available. However, there is a new trigger coil kit with new trigger
coils which will fit older engines.
For easier adjustment, on the new trigger coils ("clip on pick up“), the attachment
has been changed from a cylindrical hole with centering (21) to a elongated hole
(22).
The gap (IH02) between the trigger coil and the trigger cam must be adjusted
using a feeler gauge. On trigger coil with oblong hole, 5 washers, part no. 827800
(23) are also needed for the fastening.
■
CAUTION : As the trigger coils are no longer centered and the screw has
clearance in the oblong hole, during adjustment of the gap
(IH02), all trigger coils must be pressed clockwise up to the limit
stop.
■
CAUTION : Fit the cable clamps in such a way that there is adequate
grounding between the shielding and the ignition housing.
