3.20.6 Oil lubrication. All components shall be filled to the operating level with the grades
of oils conforming to MIL-L-2104 or MIL-L-2105 as required for the application, for use in the
temperature range at destination. A tag shall be attached in a conspicuous place to indicate the
temperature range and grade of lubricant used.
3.21 Fungus and moisture resistance. The electrical circuitry, including all components and
connections, shall be protected from the effects of moisture and fungus growth by an overall
treatment with varnish conforming to MIL-V-173 except 1 percent copper 8-quinolinolate
(by weight) based on the nonvolatile content of the varnish shall be used in lieu of salicylanilide,
the specified fungitoxicant, with the following exceptions:
(a) Components or circuit elements which are inherently fungus and moisture resistant
or which are hermetically sealed need not be treated.
(b) Components or circuit elements whose functions will be adversely affected by the
varnish coating shall not be treated.
When used, varnish shall be applied by spray, brush, or a combination of both to give a
minimum dry-film thickness of 1 mil to component and element surfaces previously cleaned and
prepared so that the surfaces are free from all foreign matter which would interfere with the
adherence or functioning of the varnish.
3.22 Lifting attachments. The crusher and sections (see 3.17.2 and 3.17.3) shall be provided
with lifting attachments. The attachments shall enable the crusher and each section to be lifted in
normal traveling or operating position. The attachments shall be located so that not less than
1-inch clearance is maintained between the slings and exterior parts of the crusher or section
being lifted. Spreader bars are permitted. Each section shall be of sufficient strength to carry not
less than 2-1/2 times the normal load imposed on the attachment. Attachments for the multiple
slings shall be located so that the attached slings will converge not more than 19 feet above the
lowest extremity of the load. Attachments shall be positioned so that the lifting strain will be in
line with the longitudinal axis of the eye of the attachment. The inside diameter of the eye shall
not be less than 3 inches. Attachments shall be attached to members of sufficient strength to
withstand stresses in the amount and direction of pull specified for the attachment. Where
required, reinforcements shall be used to meet the requirements specified herein. Lifting
attachments may also be used as tiedown attachments when such attachments meet the
requirements specified in 3.23.
3.23 Tiedown attachments. The crusher and sections shall be provided with integral
attachments to permit tiedown of the crusher or sections to the floor or deck of the transportation
medium. The tiedown attachments shall withstand dynamic loads encountered during transport,
and static loads of 8G forward, 8G rearward, 2-1/4-G upward, and 1-1/2-G sideward, where G
equals the maximum shipping weight of the crusher or section. Each section and structural
member to which the attachment is fastened shall withstand its proportion of the static load
