O
Overhaul
That maintenance effort/service/action necessary to restore an item to a
completely serviceable/operational condition as prescribed by maintenance
standards in appropriate technical publications.
Overheating
A condition indicated by discoloration of parts which usually results in a loss of
hardness. Usually caused by lack of lubrication, malfunction of parts, or excessive wear.
P
