That's a roger.

'Way back when... late 60's or early 70's... DOD's POL czar issued a
notice to add Molybdenum Disulfide to the tranny & differentials of
ALL rolling & tracked stock. This was extremely unusual since these
people are ultra conservative with regard to additives. Their Notice
was backed up by the usual bum-fodder. This was soon followed by a
similar notice from BuAir to do the same thing a (ie, add MoS) to the
GPU's & line tractors. The stuff came in a little olive-drab can
about the size of a fruit juice can. The Moly was in a suspension of
90W gear lube and you had to scrape the can to be sure of getting it
all out. We put it in our trannys, differentials, winch gear-boxes
and engines. Some guys even put in GPU's and line tractors :-)

The handiest applicator was a squeeze-tube of the stuff, sold by
FLAPS. You could order it from J.C.Whitney if you couldn't steal it
from your uncle Sam.

Moly lube for CV joints is one of those 'secret weapons' used by
professional engine assemblers, especially with regard to the cam &
tappets. I think I showed a tube of it in my blog article about
chemicals needed when assembling an engine.

Don't stop with your engine. If you've got any tools in your shop
(lathe, mill, etc.) adding Moly Lube to any gear train virtually shuts
down wear. You can actually HEAR the thing running quieter. Ditto
for gunsmithing, although you've got to be careful about using too
much. Use a match-stick or toothpick to add just a dot of moly lube
to friction points, especially in the locks of muzzle loaders.

Moly is one of those things that works so well -- and has been around
for so long -- that you ASSUME everyone is aware of it. But you still
run in to those 'instant' experts showing kids how to assemble an
engine who never mention the stuff.

PS -- DOD = Department of Defense. POL = Petroleum, Oil &
Lubricants. (DoD has a POL lab at Ft. Knox (I think). Among other
things, they test lubricants purchased by DoD.) CV = Constant
Velocity, as in the CV joints on most modern-day trannys.
