    • 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.
