3.14) Ignition electric set removal
See Fig. 74-23
The ignition electric set, consisting of 2 electronic modules and 4 dual ignition
coils, is fitted to the engine on 3 rubber buffers. For removal, detach all 8 spark
plug connectors (1) from the spark plugs. Cut the tie wraps for the 4 lower spark
plug connectors, unscrew the resistance spark plug connectors and draw the
ignition cables with protection hose through the cylinder heads. Take care not
to lose the ignition cable identification rings.
â—† NOTE: On engines with hydraulic propeller governor, it is necessary to
also remove the resistance spark plug connectors of the 2 upper
spark plugs of cylinders 2 and 4 to allow easy removal of the
ignition cables.
Cut all tie wraps (2) for ignition cable attachment and the plug connectors.
Remove cable clamp (3) and grounding cable (10) after removal of allen screw
M5x25 (4) at the electronic module. Mark the two plug connections (5) of the
pickup cables and the plug connection of the red charging cable and remove
them (see 74-00-00 sec. 3.13 respective wiring diagram for ignition unit). Detach
both attachments (6) of the ignition electric set (1 x M6 on ignition housing and
1 x M8 on crankcase).
Remove 4 allen screws M6 (7) from each of the two intake manifolds (8). Now
the 2 intake manifolds (8) with O-rings, resonator line (9) and ignition electric set
can be removed, proceeding with great care. Plug all 4 intake apertures to avoid
entry of foreign objects
