FORMAT

Work Package (WP) Format

Each chapter in this NMWR is divided into WPs, which group data into stand-alone informational or task-oriented units. As shown in table 1, chapter 1 contains informational WPs, while chapter 2 contains primarily task-oriented WPs (maintenance procedures), followed by supplementary information WPs.

Here are some important things to know about the WP format:

• Each WP has its own identification number, which appears in the upper right corner of each page. WPs are numbered sequentially throughout the manual.

• Each WP starts with page number 1. Page numbers appear at the bottom of the pages, following the WP number.

• Informational WPs begin with a listing of the specific topics covered, in the order in which they appear in the WP. This listing provides you with a quick overview of each WP and enables you to locate specific information easily.

• Each task-oriented WP begins with an Initial Setup list that identifies all tools, mandatory replacement parts, personnel, and other materials needed to complete the procedure in the WP.

The Initial Setup section also identifies the equipment condition required before the procedure can be started. Before you begin a procedure, review the Initial Setup information to ensure that all requirements have been met.

• The task-oriented WPs (maintenance procedures) appear in the manual in the order of logical work sequence. This format makes the NMWR easy to follow and helps improve efficiency as you progress through the procedures.

Text and Illustration Modular Layout

Throughout this NMWR, WPs are set up in two-page modular layouts. This means that illustrations appear either on the same page as, or on the page facing, the step you are performing. This feature eliminates the need to search for illustrations that correlate with each procedural step.

In addition, procedural text is cross-referenced to numerical callouts in the illustrations, helping you immediately identify and locate specific parts mentioned. Callout numbers referencing the illustrations appear in parentheses in the text.

vii/viii blank

NMWR 9-2920-328

SPECIAL FEATURES

Illustration Features

This NMWR utilizes a variety of illustration methods, such as locator views and exploded views, to help you locate and identify parts easily. Each illustration is identified by a title printed below it.

The illustrations contain numerical callouts to identify parts, components, etc. mentioned in the text.

Generally, callouts appear in clockwise order in the illustrations, beginning at the 11 o’clock position.

A special feature of this NMWR is that callout numbers for mandatory replacement parts are circled in the illustrations. This visually distinguishes mandatory replacement parts from those that may be repairable or otherwise reusable.

Supplemental Information

The WPs at the end of this NMWR contain supplemental information that supports the procedures in the NMWR. This information is cross-referenced to the items listed in the Initial Setup section of each task-oriented WP. The following supplemental information is included in this NMWR:

GENERAL MAINTENANCE INFORMATION (Contd)

ASSEMBLY

Cleanliness is essential in all component assembly operations. Dust and dirt, even in minute quantities, are abrasive. Parts must be kept clean.

See individual WPs for specific assembly instructions.

Replace any part that does not pass visual inspection or that is outside specified wear limits listed in the maintenance WPs or in WP 0012 00.

Follow WP instructions for coating bearings, bushings, gears, shafts, seals, friction parts, and other contact surfaces with operating oil (differential oil for differential parts, steering gear fluid for steering gear parts, etc.) to ensure lubrication of parts during initial operation after overhaul. For additional information on bearing lubrication and installation, refer to TM 9-214.

Seal handling:

1. Do not open seal packets until ready to install seal. Seals may become contaminated with dust or dirt and some types of seals can absorb moisture, which may cause damage during installation and/or shorten the lifespan of the seals.

2. Ensure lip-type seals are installed so spring-loaded lip faces toward lubricant.

Tighten all capscrews, screws, bolts, nuts, and fittings to torque values as specified in maintenance WPs and in torque specifications in WP 0011 00.

For parts identification, refer to WP 0018 00.
