Saw this post on the 599 DX Association Reflector - might come in hand for
those rusty tower bolts.

BTW, this is Lew King, W5LEW, K5GIT's brother-in-law, who was hanging out
some at McDonald's with the HCARC Wednesday morning gang this past Fall.
I'm over in Mississippi in the motorhome for the winter and will be
WorKamping again this summer in Colorado.  However, I'll be back in
Kerrville briefly in late April and will try to pop in at McDonald's to
catch up on you guys.  We were also in that 16 mile wide monster hail-storm
here in the Jackson, MS area that made the national news last week - had
baseball and softball size hail here in my RV park!  Damaged both motorhome
and van - the van got the worst damage with a shattered windshield - it's
estimated that 10,000 homes and vehicles were damaged in the Jackson area.

"Machinist's Workshop" recently published information on various penetrating
oils. The magazine reports they tested these products for "break out torque"
on rusted nuts and bolts. A subjective test was made of popular penetrating
oils, with the unit of merit being the torque required to remove the nut
from a "scientifically rusted" bolt.

 

Average torque load to loosen nut:

No Oil used ........................516 foot pounds

WD-40 ..................... ........238 foot pounds

PB Blaster .........................214 foot pounds

Liquid Wrench ......................127 foot pounds

Kano Kroil .........................106 foot pounds

ATF/Acetone mix...................... 53 foot pounds

 

The ATF/Acetone mix is a "home brew" mix of 50/50 automatic transmission
fluid and acetone. Note this "home brew" released bolts better than any
commercial product in this one particular test.

 

Our local machinist group mixed up a batch, and we all now use it with
equally good results. Note also that Liquid Wrench is almost as good as
Kroil for 20% of the price.

 

ATF/Acetone mix is best, but you can also use ATF and lacquer thinner in a
50/50 mix. ATF = Any type of Automatic Transmission Fluid. This was in one
of the Military Vehicle Club newsletters >>
