MIL-G-8968(ASG)

3.5.4.1 Component mounting. - Components that need not be removed or repositioned

for use shall be securely mounted to the generating plant in a manner that insures

against damage or unnecessary movement during operation and transport, All sub-bases

and other fixtures needed for safe and secure component mounting shall be provided and

installed.

3.5.4.2 Tubing, lines, and electrical wiring. - All tubing, lines, and electri-

cal wiring shall be located in protected positions, securely fastened to framework or

body structures, and provided with protection sleeves, grommets, or similar devices

at each point where they pass through members, except where a feed-through connector

is provided, " .

3.5.4.3 Trailer van body. - The trailer body, roof, doors, and panels in the

closed position shall provide adequate protection for the plant from damage during

storage or transport under weather conditions specified in 3.6.2 and shall be so

designed as not to warp, shrink, or delaminate in doing so. The doors and panels

shall be equipped with tiedown provisions for securing in the open position to with-

stand gusts of wind. The roof, doors, and panels in the open position shall support,

without permanent deformation, a load of 40 psf.

3.5.4.4 Center of gravity. - The generating plant overall center-of-gravity

shall be as low as practicable, Components and parts on the generating plant shall

be so mounted and positioned that the resultant forces (as calculated from the overall

center-of-gravity) will be tO the rear of the front axle when the generating plant is

decelerated at a rate of 18 feet per second per second.

3.5.5 Maintainability. - Parts and assemblies shall be located and mounted to

provide adequate clearance for repair and other maintenance and where practicable, to

permit removal and replacement of any part or assembly by removing or disconnecting

only mounting bolts or fasteners, panel doors, tubing, or control cables to the part *

or assembly being removed. The generating plant shall be designed and constructed in

accordance with the design guidelines in MIL-STD-470, paragraph entitled, "Establish

Maintainability Design Criteria", except rather than merely considered> the guidelines

shall be applied wherever appropriate to the subject class or type of equipment and

wherever they do not conflict with other requirements specified herein. Where practic-

able, the design and construction of the generating plant shall permit maintenance and

servicing under adverse weather extremes. All maintenance, servicing, and adjustment

which may be economically practicable at lower then depot level shall be capable of

being performed using only common handtools and maintenance equipment.

3.5.5.1 Operating clearances. - To the maximum practicable extent, maintain-

ability provisions shall incorporate features insuring operating clearance for

facilitating maintenance and servicing at low ambient temperatures by personnel

wearing heavy gloves or mittens and handicapped by bulky clothing and footwear.

3.5.5.2 Overtorque. - Intricate locking devices, controls, and threaded fasten-

ers that can be easily overtorqued by personnel lacking feel through thick gloves or

mittens shall be avoided where possible.
