MOPED ARMY

Yes what Roffman said.

You will need one of these to do the job (see pic below).

It is called a flywheel puller. I have the one original Puch tool available for sale.

It theads into flywheel and center bolt pushes flywheel off of crankshaft without damage. Simply bolt flywheel back on and torque when finished.

You will also need a flywheel holder. Many of those are universal and can work on any flywheel.
