TM 9-2320-361-24-1 0021 00 0021 00-2 GENERAL MAINTENANCE PROCEDURES (Contd) GENERAL CLEANING PROCEDURES (Contd) WARNING Skysol 100 mixture is combustible; DO NOT use or store near heat, sparks, flame, or other ignition sources. Use mechanical ventilation whenever product is used in a confined space, heated above ambient temperatures, or agitated. Keep container sealed when not in use. Contact with Skysol 100 may cause skin irritation. Use chemical-resistant gloves. In case of skin contact, remove any contaminated clothing and wash skin thoroughly with soap and water. Wash contaminated clothing before reuse. Eye contact may cause irritation, tearing, or blurring of vision. Use face shield or goggles when eye contact may occur. In case of eye contact, flush eyes with large amounts of water for at least 15 minutes or until irritation subsides. Inhalation may cause irritation to upper respiratory passages. DO NOT have food or drink in the vicinity. Failure to do so may result in injury to personnel. 8. Clean machined-tooled parts with Skysol 100 solvent and dry with compressed air. 9. Clean machined surfaces with Skysol 100 solvent and dry with lint-free cloth. 10. Use compressed air to blow out all tapped screw holes where gasket material covers mating surfaces. This will clear holes from any deteriorating gasket material. GENERAL INSPECTION PROCEDURES Procedures for inspections are the same for many parts and components that make up vehicle subassemblies. Dimensional standards for parts have been fixed at extremely close tolerances, so use specification tables located throughout this manual. Use specified inspection equipment for inspections where cracks and other damage cannot be seen. Exercise extreme care in all phases of inspection and adhere to the following guidelines: 1. When inspecting castings perform the following inspections: a. Inspect all ferrous and non-ferrous castings for cracks using a magnifying glass and a strong light. b. Check areas around studs, pipe plugs, threaded inserts, and sharp corners. Replace all cracked castings. c. Inspect machined surfaces for nicks, burrs, or raised metals. Mark damaged areas for repair or replacement. d. Inspect all pipe plugs, pipe plug openings, screws, and screw openings for damaged or stripped threads. e. Using a straightedge or surface plate, check all gasket mating surfaces, flanges on housings, and supports for warpage. Visually inspect mating flanges for discolorations. This may indicate persistent oil leakage. f. Check all castings for conformance to applicable repair standards. 2. Refer to TM 9-214 for inspection of bearings. Check all bearings for conformance to applicable repair standards. 3. Replace studs, bolts, and screws if threads are damaged, bent, loose, or stretched.
