HOW TO USE THIS MANUAL
Besides describing the service maintenance tasks and the intervals at which they are to be performed, two
basic levels of service are presented in this manual: engine top end service and engine bottom end service.
The manner in which these instructions are used depends upon the tasks to be performed and the level of
disassembly required.
Remove External Assemblies
To prepare the engine for service, whether top or bottom end, first see SECTION 4 - REMOVE EXTERNAL
ASSEMBLIES to remove the air cleaner, fuel tank, carburetor, etc. The order in which the topics are
presented is the order in which the assemblies are most easily removed from the engine.
NOTE: A few exceptions to this rule do exist, such as the muffler and rewind starter, which may be serviced
without having to remove other external assemblies.
Top End Service
If servicing only cylinder head components, see SECTION 5 - DISASSEMBLE ENGINE, TOP END
DISASSEMBLY, and then proceed to SECTION 6 - SERVICE ENGINE SUBASSEMBLIES, CYLINDER
HEAD. When cylinder head service is complete, see SECTION 7 - ASSEMBLE ENGINE, TOP END
ASSEMBLY.
Bottom End Service
If servicing bottom end components, such as the piston, connecting rod, crankshaft, etc., first see SECTION
5 - DISASSEMBLE ENGINE, TOP END DISASSEMBLY, and then proceed to BOTTOM END
DISASSEMBLY in the same section. When finished, move to SECTION 6 - SERVICE ENGINE
SUBASSEMBLIES, and see PISTON AND CONNECTING ROD; FLYWHEEL, CRANKSHAFT AND
CAMSHAFT; and CRANKCASE AND CRANKCASE COVER, for all service instructions. When bottom
end service is complete, see SECTION 7 - ASSEMBLE ENGINE, BOTTOM END ASSEMBLY, and then
proceed to TOP END ASSEMBLY in the same section.
Install External Assemblies
When the top and bottom ends of the engine are assembled, see SECTION 8 - INSTALL EXTERNAL
ASSEMBLIES to complete the project. The order in which the topics are presented is the order in which
the assemblies are most easily installed on the engine. These instructions also include any cleaning,
inspection, or adjustments that may be recommended.
