FIGURE 5-3 -- *BREAKER POINT SERVICE - STANDARD MAGNETO
INSTALLING MAGNETO
Timing Standard Magneto To Engine: The magneto is timed to the engine at the factory - retiming should
not be necessary unless unit has been removed fr'om the engine for reconditioning or other reasons.
Use the following steps to retime magneto to engine:
1. Turn engine over until SPK mark on flywheel
- generator fan is lined up with timing line and
pointer on the bell housing. (Remove # 1 spark plug--c
heck to insure #l cylinder is at top of
compression stroke.
)
2..
.
On magnetos with timing window, turn magneto gear (counterclockwise) until white mark lines up
with indicator.
This positions distributor for firing #l spark plug--hold in this position.
3. Position gasket then carefully guide magneto gear into engagement with idler gear--make sure whir
timing mark remains centered when installing. Secure magneto to engine.
4. Reconnect high tension leads then check ignition timing with timing light.
Timing Shielded Magneto To Engine:
Use the following procedure to insure that shielded magneto is in
time when reinstalled to engme.
STEP 1 -
STEP 2 -
STEP 3 - Make sure #I timing position of both engine and magneto are held while magneto is installed
on engine. Connect leads as shown in the accompanying illustration for shielded type magneto.
Make sure ground strap is connected to controller terminal #5. Install radio shielded plugs.
STEP
4 - After completing installation, use timing light for precision timing of the ignition.
To establish firing position of # 1 cylinder,
rotate engine by hand until timing mark on genera-
tor fan (SPK) lines up with timing mark (line) on generator housing and compression is felt in
#I cylinder (place thumb over spark plug hole).
To establish #l firing position of magneto, connect lead.to magneto terminal marked # 1.
Carefully hold end of this lead about l/W away from case and turn magneto gear in clockwise
(viewed from gear end) direction through each impulse release.
Considerable resistance
will be felt as the coupling approaches the trip point and a loud click will be heard as it
releases. Continue turning until spark is observed between #l lead and the case, then turn
gear backwards (counterclockwise) until notch in gear (and hud) lines up with yellow timing
mark on magneto flange.
