PART III consists of a Stock Number Sequence List (SNSL) and two repair parts cross lists. The SNSL lists the repair parts, arranged in National Item Identification Number (NIIN) sequence, that were provided in the COSAL to support the assigned level of support The SNSL also lists all the APL numbers each part is stocked for, the unit price, and the total COSAL quantity. The first list crosses a manufacturer's part number to a National Stock Number (NSN). The second list crosses an NSN, in NIIN sequence, to a part number. Part III is NOT a master cross reference; if the number you are researching is not included in the COSAL, it is not in these lists.

Technical Manuals

One key to effective equipment maintenance is the availability of authoritative technical data and guides for each unique item of equipment. Within the NCF, this information is supplied through the appropriate operator manuals, lubrication charts, parts manuals, and shop repair manuals. There are two types of technical manuals: manufacturer's manuals and specialized technical mantis. It is important for you to understand the difference.

Manufacturer's manuals are published by the various equipment manufacturers (Ford, General Motors, and so on). Also called factory manuals, each book covers equipment produced by that company, usually for a l-year period.

Specialized technical manuals cover only specific repair areas. They usually come in several volumes, each covering one specific section (Engine, Transmission, Hydraulics, and so forth).

A technical manual is divided into sections, such as general information, engine, transmission, and electrical. The general information section of a technical manual helps you with the vehicle identification, basic maintenance, lubrication, and other general subjects. The vehicle identification (ID) number contains a code that is used when ordering parts. The ID number identifies the type of engine, the type of transmission, and other useful information The repair sections of a technical manual cover the major systems of a vehicle. These sections explain how to diagnose problems, inspect, test, and repair each system. To use a technical manual, follow these basic steps:

Locate the right technical manual. Some manuals come in sets or volumes that cover different repair areas.

Turn to the table of contents or index. This will help you locate the information. NEVER thumb through a manual looking for a subject.

Use the page listings given at the beginning of each repair section. Most manuals have a small table of contents at the beginning of each section

Read the procedures carefully. A technical manual provides detailed instructions. DO NOT overlook any step or the repair may fail.

Study the manual illustrations closely; they contain essential information. They cover special tools, procedures, torque specifications, and other data essential to the repair.

The technical manuals (TMs) are included in the parts peculiar COSAL of each unit. The quantity of TMs is determined in the same way as repair parts. In general, this results in the following number of TMs being provided to the unit: one copy for each piece of equipment of the same make and model; two copies for two to four pieces of the same make and model; three copies for five to eight pieces of the same make and model; and four copies for more than eight pieces of the same make and model.

Regardless of the type of manual, all NCF units are responsible for maintaining, in good condition and in the proper quantities, all TMs listed in the COSAL. It is important for units to maintain inventory control of TMs through the use of periodic inventories, check-out procedures, and so on, because replacement mantis are difficult to obtain. Manuals in excess of COSAL quantities must be returned to M3 stock at CBC, Port Hueneme, California. TMs that are lost, damaged, worn out, or otherwise unserviceable, may be replaced by submitting funded requisitions to the appropriate CBC.
