The ignition electric set, consisting of 2 electronic modules and 4 double
ignition coils, is fitted to the engine on 3 rubber elements. For removal, detach
all 8 spark plug connectors Q from the spark plugs. Cut the cable straps for
the 4 lower spark plug connectors and draw the ignition cables with protec-
tion hose through the cylinder heads. Take care not to lose the ignition cable
marking sleeves.
NOTE:
On engines with hydraulic propeller governor it is neces-
sary to remove also the spark plug connectors of the 2 upper
spark plugs of cylinders 2 and 4 to allow easy removal of the
ignition cables.
Cut off cable straps W for ignition cable fixation and the plug connectors.
Remove hose clamp E and grounding cable P after removal of Allen screw
M5x25 R at the electronic module. Mark the two 4-pole plugs T of the trigger
cables and the plug connection of the red charging cable and remove them
(see Chapter 13.4.11 Wiring Diagram for ignition unit). Detach both fasteners
Y of the ignition electric set (1 x M6 on ignition housing, and 1 x M8 on
crankcase).
Remove each 4 Allen screws M6 U from both intake manifolds I. Now the
2 intake manifolds with O-rings, compensating tube O, and ignition electric
set can be removed, proceeding with great care. Plug all 4 intake apertures
to avoid entry of foreign matter.
