Cleanliness and Care, Shop Practice

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, they should be marked, organized or
retained in a specific order for reassembly.
At the time of installation, 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. These surfaces should be covered or protected to avoid component
damage.
A liberal coating of clean engine oil should be applied to friction areas during
assembly.
Proper lubrication will protect and lubricate friction surfaces during initial operation.
