INSPECTION-ACCEPTANCE AND REJECTION CRITERIA Core Hole Plugs 1. Inspect core hole plugs for evidence of leakage. 2. Replace plugs if leaking or damaged. END OF TASK REPAIR OR REPLACEMENT Scope Procedures for repair will be the same for a great percentage of parts and components. To avoid repetition of instructions, general procedures for repair are detailed in paragraphs below. After repair, clean all parts thoroughly to prevent metal chips from repair operations, or abrasives used in repair operations, from entering working parts of the engine. Castings CAUTION Avoid damage to casting while using welding equipment. Refer to TM 9-237 for welding instructions. 1. Replace all castings that are cracked or do not conform to tolerances specified in repair specifications found in (WP 0106). WARNING Cleaning solvent is TOXIC and flammable. Wear protective goggles 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 cleaning solvent. Failure to comply may result in injury, illness, or death to personnel. 2. Repair minor damage to machined surfaces with a fine file, emery cloth, or crocus cloth dipped in cleaning solvent. 3. Replace all castings on which machined surfaces are burred or nicked to the point of impairing subsequent assembly or operation. 4. Repair minor warpage of amounting flange or gasket surface by working surface across a sheet of emery cloth held tightly on a surface plate or a flat surface. Finish repair by using crocus cloth in a similar manner. 5. Replace castings having flanges which are warped to the point of impairing assembly or operation. NOTE Pipe-plug threads in castings must be in good condition to prevent oil or water leakage. 6. Repair damaged pipe or cap screw threads in tapped holes with a thread tap.
