    HOW TO USE THIS MANUAL

    SCOPE.

    This technical manual contains Unit maintenance procedures for the M992A1 Carrier Ammunition, Tracked. Chapter1 contains general information; Chapter 2 contains information on general maintenance procedures and describes andillustrates troubleshooting procedures; and Chapters 3 through 22 describe and illustrate maintenance procedures forvarious systems and components. Ten appendixes and a subject index are also included in this manual.

    INDEXING.

    Four indexing procedures are used to help you locate information quickly:

    Cover index. Lists chapter titles and important parts of the manual, with corresponding page numbers.Each chapter or part listed is boxed in, with a black outer edge that is in line with the first page of that chapteror part.

    Table of contents. The table of contents follows the Safety Summary. The table of contents lists allchapters numerically, with corresponding page numbers.

    Chapter indexes. Each chapter starts with a numerical listing of all paragraphs in that chapter.

    Alphabetical index. The alphabetically arranged subject index starts on page Index 1.

    MAINTENANCE TEXT AND ILLUSTRATIONS (CHAPTERS 3 THROUGH 22).

    Each chapter begins with a numerical listing of all paragraphs. The first paragraph in each chapter is titled “General”and describes the system(s) to be covered. General repair and inspection procedures may also be given.

    Each paragraph contains the following information, as appropriate:

    The common or specials tools and test equipment required to perform the procedures are listed under theheading “Tools/Test Equipment.” Common and special tools are listed in Appendix I.

    Materials and mandatory replacement parts that will be discarded during the procedure are listed underthe heading “Materials/Parts.” A Materials/Parts list does not contain items that maybe replaced if founddefective during inspection. Also, the list does not contain the item named in the paragraph title.Materials may be found in Appendix D. Mandatory replacement parts maybe found in Appendix H.Refer to TM 9-2350-287-24P for information on other parts that may have to be replaced.

    If more than one person is required to perform the procedure, the number is specified under the heading“Personnel Required.”

    Technical manuals, technical bulletins, field manuals, or other reference material that maybe requiredto perform the procedure are listed under the heading “References.” Note that the titles of all publicationsand forms referenced in the manual are listed in Appendix A,

    Procedures that must be performed on the vehicle prior to the maintenance procedure are listed underthe heading “Equipment Conditions.”

    iii

  • TM 9-2350-287-20-2

    TEXT AND ILLUSTRATIONS.

    Maintenance procedures are to be performed in the sequence given in the text and illustrations.

    Illustrations are numbered clockwise, beginning at the 11 o’clock position. Because an illustration is keyed to the text,parts that are removed sequentially may not have sequential numbers. For example:

    1. Remove screw (4), Iockwasher (6), washer (7), and bracket (5) from transmission.

    IMPORTANT.

    Be sure to read the entire paragraph before beginning a maintenance procedure. Also, read the general informationin Chapter 1 before beginning a procedure.

    Warnings and cautions appear immediately preceding the step to which they pertain. It is important to read andthoroughly understand the warnings and/or cautions before beginning maintenance.

    Notes may precede or follow the steps to which they pertain, depending on what makes the most sense. Notes highlightessential operating or maintenance procedures, conditions, or statements.

    PROBLEM SOLVING.

    The best way for you to fulfill your responsibility for maintaining the equipment covered in this manual is to makemaximum use of your maintenance manual. The following three sample problems illustrate ways to use the manualefficiently:

    1. How do I replace the roadwheel hub?

    • Look in the subject index for "roadwheel hub replacement” and turn to theappropriate page.

    2. An equipment condition for replacing surge tank hoses (para 6-4) is, “Powerpackremoved (para 3-2). ” How do I find out what page paragraph 3-2 begins on?

    • Look in the chapter index for Chapter 3 until you find paragraph 3-2, PowerpackReplacement; then turn to the appropriate page.

    3. The auxiliary power unit (APU) engine won’t start. How do I find out what’s wrong?

    Turn to the Quick Guide to Troubleshooting (para 2-18). Find the name of the itemthat doesn’t work (APU).

    Find the problem (ENGINE CRANKS BUT FAILS TO START) in the listing for APU.

    Turn to the paragraph in the Troubleshooting Chart (para 2-19) that is referenced-in this case, paragraph 2-19u (1).
