somewhere back down the road I heard tell that WD40 is actually not a
lubricant, it is a water displacement fluid primarily, with only a trace of
lubricant in it.. I know if you spray a squeak with it it comes back real
soon..
on of my favorite products is KROIL. has 1 micron particles, is a
penetrating oil. gets in to everything, we used it on the bridges for frozen
pins in
the rocker boxes and such.

Not wanting to tear down my pto, I tried to lube the
shaft of the pto with wd 40. Seemed to help but far
from curing the freq shifts I was experiencing when
tuning the rig. So decided to try something different.
I have on hand a product called Tetra 500. It is a
polymer and not a oil. Very fine particles in the lube
are rubbed into the surface of bearing mechanicaly.
Since it is synthetic it should not harden. So first I
sprayed the shaft of the pto with tuner cleaner and
ran the dial up and down the band several times.
Seemed to help loosen up that stiff grease in the pto.
I then applied one drop of the tetra product with a
screwdriver and sprayed again with the tuner cleaner.
My idea was to help the tetra to penetrate into the
pto, with the thin tuner cleaner, and it seemed to
work. I have had this rig since 1984 and can not
recall it working any better than it is now. No shift
in freq and very easy to turn. Will it stiffen up in
the future? I don't know, but the advertisement says
tetra is rubbed into the microscopic pores of the
metal so I am hopeful that it is a permanent cure. Btw
i do not sell or work for the company.
