Flywheel

The magnetic flywheel is located on the left end of the crankshaft, and is located inside the red circle in the photograph below. In conjunction with the stator and regulator/rectifier, the flywheel generates the electricity which charges the motorcycle's battery. If you need to replace the camshaft timing chain, you will need to remove the flywheel.



Removing the Flywheel and Stator

Drain the motor oil, then remove the stator cover. The stator is installed inside the stator cover, as shown inside the orange oval of the photograph below. Disconnect the stator wires from the wiring harness before removing the stator cover. Also remove the hose for the oil contaminant separator (OCS), which is shown inside the yellow circle in the photograph below.



Secure the flywheel with a flywheel holder, such as the one shown below.



Hold the flywheel, and remove the 28 mm nut and washer. To remove the flywheel from the crankshaft, you will need a flywheel puller tool. The Zongshen RX3 uses the same flywheel puller as the latest models of the Honda CRF250R, and CRF450R motorcycles; it has Motion Pro part #08-0372.

You can also purchase the same flywheel puller from other manufacturers, with different part numbers. For example, this Tusk Flywheel Puller will work as well.

Tighten the 28 mm barrel of the flywheel puller to the threads on the counter shaft. Hold the 28 mm barrel with a wrench, and tighten the bolt of the flywheel puller until the flywheel separates from the counter shaft.

After the flywheel is removed you will have easy access to the timing chain sprocket, and the camshaft timing chain.
