General Information
Statement on Cleanliness and Care
An automobile engine is a combination of many machined,
honed, polished and lapped surfaces with tolerances that are
measured in the thousands of an millimeter (ten thousands of an
inch).
Accordingly, when any internal engine parts are serviced, care
and cleanliness are important.
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.
• A liberal coating of engine oil should be applied to friction
areas during assembly to protect and lubricate the surfaces
on initial operation.
• Whenever valve train components, pistons, piston rings, con-
necting rods, rod bearings, and crankshaft journal bearings
are removed for service, they should be retained in order.
At the time of installation, they should be installed in the
same locations and with the same mating surfaces as when
removed.
• Battery cables should be disconnected before any major
work is performed on the engine.
Failure to disconnect cables may result in damage to wire
harness or other electrical parts.
• Throughout this manual, the four cylinders of the engine are
identified by numbers; No.1 (1), No.2 (2), No.3 (3) and No.4
(4) counted from crankshaft pulley side to flywheel side.
