GENERAL INFORMATION
CLEANLINESS AND CARE
An automobile engine is a combination of many ma-
chined, honed, polished and lapped surfaces with toler-
ances that are measured in the ten-thousandths of an
inch. When any internal engine parts are serviced, care
and cleanliness are important. A liberal coating of enigne
oil should be applied to friction areas during assembly, to
protect and lubricate the surfaces on initial operation.
Proper cleaning and protection of machined surfaces and
friction areas is part of the repair procedure. This is con-
sidered standard shop practice even if not specifically
stated.
Whenever valve train components are removed for ser-
vice, they should be kept in order. They should be
installed in the same locations, and with the same mating
surfaces, as when they were removed.
Battery cables should be disconnected before any major
work is performed on the engine. Failure to disconnectcables may result in damage to wire harness or other
electrical parts.
ON-ENGINE SERVICE
Caution: Disconnect the negative battery cable be -
fore removing or installing any electrical unit, or
when a tool or equipment could easily come in con-
tact with exposed electrical terminals. Disconnect -
ing this cable will help prevent personal injury and
damage to the vehicle. The ignition must also be in
LOCK unless otherwise noted.
Notice:Any time the air cleaner is removed, the intake
opening should be covered. Thiswill protect against ac-
cidental entrance of foreign material, which could follow
the intake passage into the cylinder and cause exten-
sive damage when the engine is started.
