MAGNETO TIMING PROCEDURE. (INTERNAL TIMING)
1. Remove magneto cover.
2. Loosen flange clamps and remove magneto from engine.
3. Check condition of points; replace if necessary.
4. Rotate the magneto drive shaft until a main cam lobe touches the follower of the left main breaker
assembly and adjust the breaker points to an initial opening of .016 inch. Wire feeler gauge is recom-
mended.
6. Fixed contact support may be bent to adjust clearance. If support is bent, main breaker contact must
be rechecked. Torque breaker securing screws to 20-25 inch-pounds.
– NOTE –
Bend bracket carefully. Do not correct by bending back if bent
too much; this weakens the bracket.
7. Position rotor so keyway is at 12 o’clock position and red painted distributor teeth are visible in timing
windows.
8. Loosen drive shaft nut and position the Rotor Holding Tool (Bendix part number 11-8465) under
washer or bushing on drive end of rotor shaft with clamp at 4 o’clock position so any shaft deflection
caused by clamping action will be in a plane parallel to breaker contacts. Tighten nut to secure holding
tool to shaft. Check to insure proper location of keyway and tighten adjusting screw of holding tool to
lock rotor in position.
9. Loosen rotor holding tool and turn magneto in direction of rotation until adjacent ”R”(“E”gap) mark is
aligned with pointer and lock in position. Both red painted teeth should be approximately centered in
timing windows.
– NOTE –
The use of the timing light unit, part number 11-9110-1 avail-
able from Bendix will simplify the internal timing procedure
and breaker synchronization.
10. Connect the timing light black lead to any unpainted surface of the magneto.
11. Connect the red timing light lead to the left breaker terminal and the green lead to the right main
breaker terminal. (Refer to Figure 8a.)
12. Loosen rotor holding tool and move the rotor back a few degrees; then move it forward. Both lights
should go out to indicate opening of the main breakers when the timing pointer is indicating within the
width of the “R” mark and the red painted teeth are centered in timing windows.
cam from taper. Using 11-3031 Retaining Ring Pliers inserted in holes in cam, rotate main breaker
cam in direction of rotation until left main breaker pointsj ust open and press cam onto taper. Tighten
screw to seat main breaker cam.
14. Loosen rotor holding tool to turn rotating magnet back a few degrees; then turn rotating magnet in
normal direction of rotation. Timing light should go out when timing pointer is aligned with “R” (“E”
gap) mark. Lock rotating magnet in position where points just open.
