Aerox guide: How to remove flywheel

Here I show how to loosen the flywheel.
The guide I use a couple of special tools required to remove parts without damaging them.
I also explain how the ignition works and what is important in the assembly.
Ignition is a euro 2

Forgive my bad English
I'm from Sweden..

Checkout the youtubeclip at the end It is in Swedish, but can probably help anyway

Remove the cover over the flywheel

Remove the wheels driving the water pump
Not really needed, but then they are not in the way when removing the flywheel

Flywheel tool in place

Now you can loosen the nut on the crankshaft easily

Flywheel Puller (remember that it is left-hand threads) 27x1mm

Turn down puller and push off the flywheel

This is the pickup (also called MAGNETIC SENSOR)

When the nock on the flywheel
hits the pickup, a signal is send to CDI'n
And CDI'n sends ignition pulse to the ignition coil
How it works CDI / ignition

• First, get a capacitor charged in CDI'n (voltage from the solenoid when you kick - blue "wave" in the picture above)
• Then the CDI signal from the pickup (signal "triggered" from the flywheel - blue "square" in the picture above)
  The pickup sends about 2.1 volts to CDI'n every time the magnet rotate one lap.
• When the signal came from the pickup the CDI wait a preprogrammed time before the capacitor discharges a voltage to the ignition coil
• Coil converts input voltage (400-600 volts) for a voltage of typically about 15,000 Volts - ignition coil flashes red in the image above
• The spark plug converts the incoming voltage from the ignition coil to a spark -

The feather key that allows the ignition pulse, in the right place!
Do you forget the feather key during installation will spark pulse be in the wrong place

Some troubleshooting tips (if the lights are not lit for you)
Measuring light coil
- Yellow / red wire to ground
- Should be 0.40 to 0.60 ohms

Pic 11
Measure the charge coil (if the battery is not charging)
- White wire to ground
- Must be from 0.48 to 0.72 ohms

To replace the ignition plate loosen the two bolts.

Push the cables through the hole
Ready for this time!
