pair of the subassemblies of the engine components.
Clean all parts thoroughly as the component parts are
disassembled. Only clean parts can accurately be in-
spected and gauged for wear or damage. There are
many commercially available cleaners that will quickly
remove oil and grime from engine parts. When such a
cleaner is used, follow the manufacturer's instructions
and safety precautions carefully. Particular attention
should be given to commercial cleaners compatibility'

Make sure that the cleaner is wiped off of engine parts
and not allowed to air dry as some cleaners leave a
residue on parts which can affect engine lubrication.
