TM 9-2520-272-40 0067 Cleaning Bearings Refer to TM 9-214 for procedures to clean bearings. Cleaning Oil Passages Flush with dry cleaning solvent. Removing Metal Particles Flush all parts with dry cleaning solvent. Blow parts dry with compressed air. Also blow compressed air into all pockets, cavities, and passages to get rid of trapped metal particles. Cleaning Transmission Exterior WARNING Alkaline solution is used in cleaning operations. Avoid contact of alkaline solution with eyes or skin. Contact with skin can cause rash or blisters. Scrub with soap and water. Contact with eyes can cause blindness. Flush with clean water and get medical attention immediately. The exterior of the transmission must be thoroughly cleaned before disassembly is started. Use the following methods to remove dirt, oil, grease, or sludge from the exterior surface of the transmission: To clean a slightly dirty transmission, wash with dry cleaning solvent and blow dry with compressed air. To clean an excessively dirty transmission, prepare an alkaline steam cleaning solution as follows: Use 10 lb (4.536 kg) of tribasic sodium phosphate per 50 gal (189 L) of water. Apply this solution with forced steam pressure at 50 psi (345 kPa). Degree of Cleanliness All parts must be clean enough to permit effective inspection. Minute particles left on close tolerance parts, such as valves, can cause transmission failure. Reclean parts as necessary. END OF TASK 0067‐4
