APPENDIX A
4.4.4 Winch and wire rope test. To determine conformance to 3.4.4, winch and wire rope
shall be tested with load and examined for proper assembly, installation and functional
requirements. Rated load of the winch system shall be tested at GPG. During control test at
contractor's facility, winch and wire rope shall be tested and examined as above, except no load
shall be used.
Verification Rationale
Proper and thorough testing of the winch assembly is necessary to assure a safe, reliable and
efficient vehicle retrieval system. Winch controls shall be exercised and observed for ease of
operation and proper installation.
Verification Guidance
The winch must be mounted on the vehicle in such a way that it can maintain a full capacity
pull without damage to the vehicle frame and/or components. Mounting hardware shall be
examined for conformance to specified torque. The wire rope shall be one continuous length
without a splice joint, and the ends of the cables shall have clevis ends and crescent thimbles.
Verification Lessons Learned
3.4.5 Engine. The engine furnished shall be a liquid cooled compression ignition, two stroke
or four-stroke cycle diesel engine, with not less than ______ cylinders, with a governed speed
not to exceed ______ RPM.
Rationale
The diesel engine defined above, and the engine and truck adaptation described herein shall
be designed to provide the maximum practicable interchangeability with existing vehicular parts
and components. The engine and adaptation designs shall utilize, when suitable for the purpose,
components and manufacturing processes which shall not require special, new, or costly tooling,
facilities, or procedures.
Guidance
Insert in the first blank space the number of cylinders required for the engine, and the RPM
in the second space. Design shall include emphasis on reducing the need for maintenance, repair
parts, supply and other logistic support for the vehicle. Durability and reliability shall be the
maximum attainable to minimize requirements for unscheduled maintenance and shall not be
compromised to achieve light weight. Scheduled and preventative maintenance shall be
