Section 9
Inspection and Reconditioning
This section covers the operation, inspection, and repair/reconditioning of major internal engine components.
The following components are not covered in this section. They are covered in sections of their own:
Air Cleaner, Section 4
Carburetor and Governor, Section 5
Ignition, Section 7
Clean all parts thoroughly. 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. Use gasket
remover to remove old material from the valve cover, cylinder head, crankcase, and oil pan. Do not scrape the
gasket surfaces, as this could cause damage resulting in leaks.
Make sure all traces of cleaning solvents 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.
