There are a a few different paths that can be followed when disassembling an engine. This chapter will cover the
removal of components in one order, but it is written so that the technician can jump around to the component being
removed.
The first step to disassemble the engine is to remove the engine from the application by following the steps
described in the service manual for that particular application.
1. Drain and save the oil from the engine by following the steps described in Chapter 1: Introduction.
2. Remove the fuel tank by following the steps described in Chapter 4: Fuel system and Governor.
3. Remove the starter by following the steps described in Chapter 6: Starter systems.
4. Remove the flywheel and ignition module by following the steps described in Chapter 7: Ignition system.
5. Remove the muffler by following the steps described in Chapter 8: Exhaust.
NOTE: At this point it would be a good idea to service the PCV valve by following the steps described in Chap-
ter 5: Lubrication.
6. Remove the cylinder head by following the steps described in Chapter 9: Cylinder head.
7. Clean the cylinder bore and remove all carbon.
8. Turn the engine over.
