Replace all gaskets, lockwashers, and packings.
All parts must be cleaned before inspection and assembly and after repair. If part is to be removed from vehicle, wipe off
grease and grime before removal so dirt particles will not fall into delicate engine or hydraulic components.
When working on systems where extreme cleanliness is required, steam clean parts and surrounding area before removal

Drycleaning solvent P-D-680 is toxic and flammable. Wear safety goggles and gloves and use only
in a well-ventilated area. Avoid contact with skin, eyes, and clothes, and do not breathe vapors.
Do not use near open flame or excessive heat. Flashpoint for type #1 drycleaning solvent is 1000F
(380C) and for type #2 is 1380F (590C). If you become dizzy while using solvent, get fresh air
immediately, and get medical aid. If contact with eyes is made, wash your eyes with water, and
get medical aid immediately.
Clean inner and outer surfaces of metal parts and all areas that get greasy or oily with drycleaning solvent (item 19,

Use clean water or soap (item 7, appendix C) and water to clean rubber or plastic material. Clean off rust on metallic parts
with wire brush or abrasive cloth. Use low-pressure compressed air to blow away rust and cloth particles. Clean off solder
with soldering iron. Hydraulic system components must be cleaned and dried carefully so that dirt and metal or fiber
particles cannot get into and contaminate hydraulic fluid.
Electrical parts solvent cleaning compound is flammable, and reacts violently with certain metals.
