Whenever replacing either ring gear or magneto
flywheel, Gun Kote must be applied to prevent
possible corrosion.
To apply Gun Kote proceed as follows:
1. Clean thoroughly and degrease replacement
part using a non oil base solvent.
2. Apply coating in light thin coats using a spray
gun.
NOTE:
Do not spray Gun Kote into magneto fly-
wheel threaded holes.
3. Bake parts in oven at 175° (350°F) for one hour
to cure Gun Kote.

CAUTION
Always assemble magneto flywheel and
ring gear prior to apply Gun Kote. If not done
correctly, ring gear won’t contact magneto
flywheel flange.
-
CAUTION
Do not eliminate Gun Kote heat curing time
because it will lose all its resistance and it
will not give any protection.
