Drive Gear
E-MAG ignitions are indexed to the engine through a drive
gear. The drive gear from a non-impulse magneto can be
recovered and, if in good condition, be reinstalled on your
E-MAG. Gears from an impulse magneto are different,
and cannot be reused.
To recover the drive gear from an existing magneto:
1.
Remove the cotter key, castle nut, and washers. A strap wrench is helpful
while removing (or re-installing) the castle nut from the ignition shaft.
2.
Remove the drive gear from the magneto shaft. A gear puller will be
necessary to remove the gear without damaging it, or the magneto.
NEVER strike the magneto or the gear.
3.
Install the drive gear on the E-MAG shaft using the woodruff key,
washer(s), castle nut, and cotter key provided. Your kit includes three
washers (one thick and two thin). The thick washer should always be
used. The thinner washers can be used, as needed, to align the hole for
the cotter key with the castle nut when tightened.
Make certain the cotter
key ends lay flat and do not extend past the open face of the gear. The
back wall of the accessory case will be close to the face of the drive gear,
and you don’t want any protrusions that can make contact and wear
against the back.
