1.7 OVERVIEW AND GENERAL INSTALLATION GUIDELINES
The Crew Protection Kit is an add-on system designed for use on the M915-A3, M915-A2, and
M916-A1 vehicles. These Installation Instructions were originally written specifically for the
M915-A3 application, and additional instructions were added in Revision A to adapt it for the
M915-A2 and M916-A1 models.
In order to facilitate easy assembly, there are certain steps that must be executed properly and in
the right order:

certain steps of the Air Conditioner Kit installation should be performed before the
installation of the armor.
2. Unpack the kit subassemblies according to the order of installation. The installation
sequence should follow the sequence as presented in this manual.
3. Locate / identify all the kit subassembly parts before installation.
4. Use the provided figures to identify the proper screws for each assembly. In addition,
fastener maps are provided in Section 6.

be shifted for alignment. For the M915-A2 models, complete the installation of the
Air Conditioner Kit prior to applying locking compound and tightening all fasteners.
