RE: Step by Step Procedure on How to Dismantle an Engine
Easy as pie.
1. Remove cooling head
2. Remove backplate
3. Remove liner. Put a piece of thick plastic or wood in the exhaust and push out the liner witht he piston if it's stuck. (leave flywheel on for this purpose)
4. Remove rod and piston assembly
5. Remove flyheel. A bearing puller is a useful tool for this.
6. Knock out crank shaft
No rocket science here.
