3.15 Lubrication. The pumping unit shall incorporate bearings of the sealed
pre-lubricated types.

the effects of fungus growth and moisture by an overall treatment with a varnish
conforming to MIL-V-173, composition I or II, as applicable (see 3.18.1), with
one percent copper 8-quinolinolate (by weight) based on the non-volatile content
of the varnish.
a.
Components or circuit elements that 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.
The varnish shall be applied by spray, brush, or a combination of both to give a
dry-film thickness of not less than 1 mil to component or element surfaces
previously cleaned and prepared so that the surfaces are free from all foreign
matter which would interfere with the adherence or function of the varnish.
3.18.1 Composition. Composition II shall be used only in the case when local
air pollution regulations governing the application of varnish precludes the use
