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.

While corrosion is typically associated with rusting of metals, it can also include deterioration of other materials, such as rubber and plastic. Unusual cracking, softening, swelling, or breaking of these materials may be a corrosion problem.

If a corrosion problem is identified, it can be reported using SF 368, Product Quality Deficiency Report. Use of key words such as “corrosion”, “rust,” “deterioration,” or “cracking” will ensure that the information is identified as a CPC problem.

The form should be submitted to the address specified in DA PAM 750-8, The Army Maintenance Management System (TAMMS).

STANDARDS

1. Quality of Materiel. Unless otherwise specified, parts and material used for repair or modification will comply with equipment drawings and specifications.

2. Man-Hour Standards.

a. A guide listing average time (man-hours) required for disassembly, overhaul, and assembly of an individual component or item is contained in WP 0029 00. The man-hour allowances listed are sufficient to permit the task to be accomplished properly by qualified personnel with proper tools and equipment.

b. Man-hour estimates of individual maintenance operations may vary for the following reasons:

(1) Skill and training of personnel.

(2) Experience attained from previous rebuild programs.

(3) Material handling and shop facilities.

PRESHOP INSPECTION 0003 00

PURPOSE

1. The purpose of the preshop inspection is to determine, prior to beginning overhaul activities, the extent of overhaul required to return the transmission to NMP overhaul standards.

2. A transmission assembly is considered economically repairable when the estimated cost of repair does not exceed the maximum expenditure limit for the assembly (see TB 750-98-24).

UNPACKING

WARNING

The transmission assembly weighs approximately 4125 lb (1871.07 kg). Use appropriate lifting device with a weight capacity greater than the transmission assembly when lifting or moving the transmission.

When required to unpack the transmission assembly, caution must be exercised when lifting equipment is necessary. There are no special instructions required. Do not remove tags or forms until actual overhaul is begun.

REVIEW OF RECORDS AND DATA

Physically check all tags and forms attached to the equipment to determine the reason for its removal from service and other discrepancies. Do not remove attached tags or forms until actual overhaul is begun.

PRELIMINARY CLEANING

1. Cleanliness is essential in all overhaul operations. Dirt and dust, even in minute quantities, are abrasive.

Precision-lapped surfaces of rotating parts must be protected from dust and dirt at all times. Be sure parts are cleaned as specified and be sure they are kept clean. Do not handle parts with greasy hands. Dusty and grimy clothing must not be worn.

Solvents can burn easily, can give off harmful vapors, and are harmful to skin and clothing. Wear protective goggles and gloves and don’t breathe vapors. To avoid injury or death, keep away from open fire and use in well ventilated area. If solvent gets on skin or clothing, wash immediately with soap and water.

2. Cover all openings of the transmission with tape or other suitable materials and thoroughly clean all external parts and other surfaces. Make sure that no foreign matter enters working parts. External surfaces of transmission may be steam cleaned. Remove grease and oil with cleaning compound solvent or mineral spirits applied with a stiff brush.

3. Ensure that all openings are covered to prevent entry of water or other contaminants.

4. Apply a light coat of preservative oil, MIL-PRF-21260E, type I, Grade 10, to all bare metal surfaces.

NOTE

Vapor-degreased and steam cleaned parts must be treated immediately to prevent rust.

PRESHOP INSPECTION—Continued 0003 00

IN-PROCESS INSPECTION

1. In-process inspection requirements are provided in the disassembly and assembly procedures.

2. Unless otherwise specified, used components and refinished parts recovered as products of disassembly will be examined 100 percent by the National Maintenance Management (NMM) Repair Site to determine serviceability.

3. Tolerance, wear limits, corrosion limits, torque values, and adjustments are provided for each task to which they apply.

DISASSEMBLY OF CROSS-DRIVE TRANSMISSION

1. Instructions for disassembly of the cross-drive transmission assemblies XT-1410-4 and XT-1410-5A are contained in TM 9-2520-215-34 (XT-1410-4) or TM 9-2520-590-34 (XT-1410-5A).

2. Use caution in handling parts during disassembly. Careless handling may cause subsequent failure of equipment.
