TM 9-2520-272-40 0001 CORROSION PREVENTION AND CONTROL (CPC) Corrosion Prevention and Control (CPC) of Army materiel is a continuing concern. It is important that any corrosion problems with this item be reported so that the problem can be corrected and improvements can be made to prevent the problem in future items. Corrosion specif cally occurs with metals. It is an electrochemical process that causes the degradation of metals. It is commonly caused by exposure to moisture, acids, bases, or salts. An example is the rusting of iron. Corrosion damage in metals can be seen, depending on the metal, as tarnishing, pitting, fogging, surface residue, and/or cracking. Plastics, composites, and rubbers can also degrade. Degradation is caused by thermal (heat), oxidation (oxygen), solvation (solvents), or photolytic (light, typically UV) processes. The most common exposures are excessive heat or light. Damage from these processes will appear as cracking, softening, swelling, and/or breaking. SF Form 368, Product Quality Def ciency Report, should be submitted to the address specif ed in DA PAM 750-8, The Army Maintenance Management System (TAMMS) Users Manual. DESTRUCTION OF ARMY MATERIAL TO PREVENT ENEMY USE Refer to TM 750-244-6 for methods and/or procedures needed for destruction of Army materiel to prevent its use by enemies. PREPARATION FOR SHIPPING OR STORAGE OVERVIEW The X200-4A Transmission is installed in a protective container for storage or shipment. Dependent upon the condition of the transmission, transmissions may be installed and removed at the Field Maintenance, Depot Maintenance, or Below Depot Maintenance levels of maintenance. Unserviceable transmission assemblies in reusable shipping and storage containers are returned to Depot Maintenance. Refer to WP 0002 for more information about the shipping and storage container. Transmission assemblies repaired at the Sustainment Maintenance level are usually reinstalled in the vehicle. Sometimes a repaired transmission assembly in a reusable shipping and storage container is to be returned to Field Maintenance or retained in long-term storage. Unserviceable transmission assemblies are often sent in a reusable shipping and storage container to Depot Maintenance. Proper preparation for packing the transmission assembly in a reusable shipping and storage container is important. The transmission assembly should be clean and drained of f uid. All appropriate plugs and covers should be installed on all inlets and outlets. Refer to the Field Maintenance manual for the X200-4A Transmission, TM 9-2350-277-13&P, for detailed instructions on installing the transmission in or removing the transmission from the reusable shipping and storage container. 0001‐2
