CYLINDER AND PISTONS

Clean Piston

A. Remove the piston and piston rings (see Remove
Piston in Section A).
B.
Never clean the piston head with the engine assembled. Carbon
particles will fall between the piston and cylinder, and damage
the crankshaft bearings.
Use the scraping tools carefully. Do not gouge the piston head.
To avoid gouging, use scrapers that are made of a material that
will not cause damage.
Scrape the carbon off the piston head with a scraper [A].
