d. Ball and Roller Bearings. When cleaning ball or roller bearings, place them in a basket and suspend them in

a container of drycleaning solvent. If needed, use a brush to remove caked grease, chips, etc. Avoid rotating bearing

before solid particles are removed to prevent damaging races and balls. When bearings have been cleaned, coat them

lightly with lubricating oil to remove solvent.

Do not clean tires, lubricant seals, rubber hoses, or electrical components with solvent mixture.

e. Rubber Parts. Do not clean preformed packings or rubber parts in drycleaning solvent. Wipe parts clean with

a dry, lint-free cloth.

Steam cleaning creates hazardous noise levels and severe burn potential. Eye, skin, and ear

protection is required. Failure to comply may result in injury to personnel.

f. Exterior Parts. Steam clean all exterior parts thoroughly before removing. This will make inspection and

disassembly easier.

Solvents used with a spray gun must be used in a spray booth with filter. Face shield must be

used by personnel operating spray gun. Failure to comply may result in injury to personnel.

g. Engine, Cab, and Body. Use a spray gun and solvent mixture for cleaning exterior of engine, cab, and body.

Allow mixture to remain on item surface for 10 minutes before rinsing. Rinse with hot water under 80 to 120 pounds

of pressure, if available. An ordinary garden hose with nozzle may be used if other equipment is not available. Rinse

thoroughly.

To prevent corrosion, parts should be dipped in rust preventive within two hours of degreasing.

Degreasing Machine. A degreasing machine may be used to remove heavy grease and oil from metal parts.

i. Passages. After degreasing, check all oil passages and cavities for dirt or blockage before coating with rust

preventive. Run a thin, flexible wire through oil passages to make sure they are not clogged. Use a pressure spray gun

and drycleaning solvent to clean dirty passages.

j. Electrical Parts. Electrical parts, such as coils, junction blocks, and switches should not be soaked or sprayed

with cleaning solutions. Clean these parts with a clean, lint-free cloth moistened with drycleaning solvent.
