f. Remove the plug from the distributor inspection windows at either end of the
magneto housing. (Refer to Figure 8-14.) Also remove the plug from the "E" gap inspection
window on the data plate side of the magneto housing. (Refer to Figure 8-15.)
g. Turn the rotating magnet drive shaft in the normal direction of magneto rotation
until the red distributor tooth appears in the distributor inspection window, and also check
to see if the letter "K" appears in the "E" gap inspection window on the data plate side. If
the letter "B" is in the window, turn the magneto shaft 1-1/2 times in the direction of
rotation and check again to be sure the "K" is in the window on the data plate side and the
red distributor tooth appears in each distributor inspection window.
h. Install the magneto to engine gasket on the magneto flange.
i. Feel the magnet into its No. 1 neutral position as described in Step g. With the
engine in its recommended No. 1 cylinder firing position of 20 BTDC, place the magneto
in position on the engine mounting pad and secure with the flange clamps finger tight.
j. Install short adapter leads made from Bendix terminal kit (part number 10-382698)
into magneto switch terminals and connect to Bendix timing light (part number 11-91 10) or
equivalent.
k. Bump the magneto in the direction opposite the normal shaft rotation until the first
breaker opens. Due to normal tolerances, one breaker may open slightly before the other
and timing should be done to the first or early breaker. Evenly tighten the magneto
mounting clamps.
