I used The ATF/Acetone mix of 50/50 automatic transmission fluid and acetone.
"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 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 Kriol .........................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
(quoted from post at 11:28:41 11/20/15) If your tractor has wet sleeves you can remove the connecting rod bolts and drive out the sleeve and piston using a piece of 2x2 oak and a big hammer.

old rods. Pull the crankshaft and have it measured for wear. A good time to renew the clutch disc.. I did this in 1975 on a Farmall A. Hal
