3.29 Lubricants. Unless otherwise specified herein, the crane shall
be serviced with military lubricants selected by the contractor in
accordance with table I, SAE J754. Run-in and testing shall be
performed with these lubricants as applicable for the ambient
operating temperature. A lubrication data plate identifying military
lubricants and applicable temperature ranges shall be provided and
mounted (see 3.32.1) on each crane.
3.29.1 Lubrication fittings. Lubrication fittings shall conform to
SAE J534. Fittings shall be located in a protected accessible
position. Fittings shall be accessible to a grease gun conforming to
MIL-G-3859, equipped with a hydraulic coupler conforming to MS24207
and a 10-inch flexible extension. Accessibility to fittings shall be
provided without the removal or adjustment of accessories or parts.
Panels and plates equipped with handoperated fasteners may be removed
to provide accessibility. Accessibility shall be in accordance with
SAE J925 for personnel normally clothed.
3.29.2 Enclosures with integral reservoir of lubricant Enclosures
.
such as the gearcases, transmission housing and engine crankcase,
which contain a reservoir of liquid lubricants for the lubrication of
the parts enclosed, shall be equipped with dipsticks, marked in
accordance with SAE J614, check plugs not less than 1/2-inch pipe
size, or sight gages to determine the acceptance level of the
lubricant. Each enclosure shall be equipped with a means for filling
the enclosure with lubricant and for draining. The drain, except
planetaries, shall be fitted with a SAE J531 or J532 magnetic
drainplug. The drainplug shall be located so that removal of the plug
will result in complete drainage of the lubricant from the enclosure.
Drainage, except from planetary hubs, shall be to a container on the
ground when the crane is on level ground. Integral tubes or troughs
may be used to convey the lubricant from the drain to the container.
Accessibility to the drainplug, the filling means, and the lubricant-
level checking device shall be provided without the removal or
adjustment of accessories or parts. Plates equipped with hand-
operated fasteners may be removed.
3.30 Fungus and moisture resistance Electrical circuitry,
.
including all components and connections except as specified below,
shall be protected from the effect of fungus growth and moisture by
an overall treatment with a varnish conforming to MIL-V-173,
composition specified in 3.30.1:
a. Components or circuit elements which are inherently fungus and
moisture resistant or which are hermetically sealed need not be
treated.
b. Components of circuit elements whose functions will be adversely
affected by the varnish coating shall not be treated.
When used, the varnish shall be applied by spray, brush, or a
combination of both to give a minimum dry-film thickness of 1 mil to
component or element surfaces previously cleaned and prepared so that
the surfaces are free from all foreign matter that would interfere
with the adherence or function of the varnish.
