CYLINDER BLOCK REPAIR AND DE-GLAZING INSTRUCTIONS (CONT)

TM 9-4940-568-34 7-7 · Drycleaning Solvent (P-D-680) is TOXIC and flammable. Wear protective goggles, face shield, and gloves; use only in a well-ventilated area; avoid contact with skin, eyes, and clothes, and do not breathe vapors. Keep away from heat or flame. Never smoke when using solvent. The flashpoint for Type II Drycleaning Solvent is 140 degrees F (60 degrees C) and Type III Drycleaning Solvent is 200 degrees F (93 degrees C). Failure to do so may result in injury or death to personnel. · If personnel become dizzy while using cleaning solvent, immediately get fresh air and medical help. If solvent contacts skin or clothes, flush with cold water. If solvent contacts eyes, immediately flush eyes with water and get immediate medical attention. (2) Wash the cylinder bores with drycleaning solvent. Use a nylon brush to clean all oil passages. Build up of deposits in coolant passages can cause engine overheating. Excessive deposits can be cleaned in an acid tank, but the cam bushing must be removed first (Para 7-7). Failure to follow this procedure could cause damage to the equipment. (3) Make sure coolant passages are clean. High pressure steam can blow particles into eyes, can cause severe burns, and creates hazardous noise levels. Eye, skin, and hearing protection is required. (4) Steam clean cylinder block. Ensure oil and water galleries are cleaned thoroughly.
