Cleanliness and Care
SIE-ID = 19007
• Throughout this section, it should be understood
that proper cleaning and protection of machined
surfaces and friction areas is part of the repair
procedure. This is considered standard shop
practice even if not specifically stated.
• When any internal engine parts are serviced, care
and cleanliness is important.
• When components are removed for service, the
components should be marked, organized or
retained in a specific order for re-assembly.
• At the time of installation, the components should
be installed in the same location and with the
same mating surface as when removed.
• An automobile engine is a combination of many
machined, honed, polished and lapped surfaces
with tolerances that are measured in millimeters or
thousandths of an inch. The surfaces should be
protected to avoid component damage.
• Apply a liberal amount of clean engine oil to
friction areas during assembly.
• Proper lubrication will protect and lubricate friction
areas during initial operation.
Replacing Engine Gaskets
SIE-ID = 66654
Gasket Reuse and Applying Sealant
• Do not reuse any gasket unless specified.
• Gaskets that can be reused will be identified in
the service procedure.
• Do not apply sealant to any gasket or sealing
surface unless specified in the service procedure.
Separating Components
• Use a rubber mallet in order to separate the
components.
• Bump the part sideways in order to loosen the
components.
• Bumping of the component should be done at
bends or reinforced areas of the component
to prevent distortion of the components.
Cleaning Gasket Surfaces
• Use care to avoid gouging or scraping the sealing
surfaces.
• Use a plastic or wood scraper in order to remove
all the sealant from the components.
Do not use any other method or technique to
remove the sealant or the gasket material from
a part.
• Do not use abrasive pads, sand paper, or power
tools to clean the gasket surfaces.
− These methods of cleaning can cause
damage to the component sealing surfaces.
