Overhaul Manual
O-360 and IO-360 Series Engines
NOTE:
While rotating the magneto shaft
backwards with alignment pin in hole, if
the shaft stops turning due to internal
interference against the alignment pin
prior to pin seating, pull pin out just far
enough to allow the shaft to continue to
rotate. Re-insert the pin and continue
rotation until the pin seats as previously
described. This procedure locates the
magneto at the No.1 cylinder firing
position.
(8) Repeat for the 2nd magneto’s
alignment.
(9) Bring the engine to the compression
stroke on the No. 1 cylinder.
(10) Rotate engine to approx. 25º before top
dead center using a timing indicator
installed in a spark plug hole of the No.
1 cylinder or equivalent method.
