13.4.13) Removal of trigger coil set

Effectivity: 912 Series
AIRCRAFT ENGINES
MAINTENANCE MANUAL II
See fig. 106 and 107.
Because of the shielding Y the trigger coil T set can be exchanged only
in pairs. Remove the attachment screws U with the distance sleeves I
and clamps and re-fit new trigger coil set. The stator O need not be
removed in this case.
The trigger coil Q is adjustable only to a limited extent. The gap W between
pick-up and trigger cam E is dimension U in para 15. The axial position
of the triggers should be in the middle over the trigger cam and may be
offset by max. dimension I in para 15.
NOTE: The two trigger coils for ignition circuit A (marked red and
blue on cable ends) are fitted in the higher position, on
distance sleeves T, these of ignition circuit B are fitted
in the lower position.
CAUTION: Fit the clamps as to ensure perfect ground connection
between shielding and ignition housing.
