Section 9
Disassembly
WARNING: Accidental Starts!
Disabling engine. Accidental starting can cause severe injury or death. Before working on the engine or
equipment, disable the engine as follows: 1) Disconnect the spark plug lead(s). 2) Disconnect negative (-) battery
cable from battery.
The following sequence is suggested for complete
engine disassembly. This procedure can be varied to
accommodate options or special equipment.
Clean all parts thoroughly as the engine is
disassembled. Only clean parts can be accurately
inspected and gauged for wear or damage. There
are many commercially available cleaners that will
quickly remove grease, oil, and grime from engine
parts. When such a cleaner is used, follow the
manufacturer’s instructions and safety precautions
carefully.
Make sure all traces of the cleaner are removed
before the engine is reassembled and placed into
operation. Even small amounts of these cleaners can
quickly break down the lubricating properties of engine
oil.
