TM 9-2815-220-24 FUEL INJECTION NOZZLE REPLACE/REPAIR 0114 00 CLEANING WARNING Carbon-Removing Compound is mildly toxic. Compound evaporates and fumes should not be inhaled. Continued contact with compound can cause skin problems. • • • • Avoid inhalation of fumes. Provide adequate ventilation. Avoid contact with skin. Use goggles, rubber gloves, and rubber apron If compound is splashed on skin, flush with fresh water and wash with alcohol. Alcohol containing 2 to 3 percent camphor is preferred. CAUTION Do not use sharp tools, wire brushes or abrasive materials to clean the nozzle valve or nozzle body. Do not clean orifices with cleaning wire as this method will distort nozzle orifices and also may block opening due to wire breakage. 1. Soak nozzle valve (27) and nozzle body (28) in carbon removing compound (item 7, WP 0173) to remove major carbon deposits. Remaining carbon deposits should be removed using a soft cloth (item 10, WP 0173) or felt pad. 2. Make sure spray orifices in nozzle tip (26) are clear. CAUTION Be sure hands are kept free from accumulation of grease which will cause collection of dust and grit on parts. 3. Clean all remaining nozzle components in accordance with procedures in Work Package 0028. 4. Cover or wrap all parts after cleaning to protect them from dirt accumulation. 28 27 26 WP 0114 00-10
