OVERHAUL TIPS

Aluminum has become extremely popular for use in engines, due to its low weight. Observe the following precautions when handling aluminum parts:

• Never hot tank aluminum parts (the caustic hot tank solution will eat the aluminum.
• Remove all aluminum parts (identification tag, etc.) from engine parts prior to the tanking.
• Always coat threads lightly with engine oil or anti-seize compounds before installation, to prevent seizure.
• Never overtighten bolts or spark plugs especially in aluminum threads.

When assembling the engine, any parts that will be exposed to frictional contact must be prelubed to provide lubrication at initial start-up. Any product specifically formulated for this purpose can be used, but engine oil is not recommended as a prelube in most cases.

When semi-permanent (locked, but removable) installation of bolts or nuts is desired, threads should be cleaned and coated with Loctite(r) or another similar, commercial non-hardening sealant.
