Best Penetrating Juice?

Ox · Mar 15, 2017

I've got a Kurt that is tied up dog-fast.

I've been on it hard enough that it is very impressive that I haven't twisted the shaft into a pretzel.

So - I'm wonderin' what kind of miracle juice I can dribble down inside and leave soak?

I always use Kroil. That's what we always used when I was a kid. I can't say I've tried many others.

Put the whole thing in a tub (submerged) of diesel fuel.
Maybe put an air impact on it slightly subdued (turn down the pressure) to rattle the crud loose.

We sometimes use Mineral Spirits for stuff like that.

EDTA and water, and time. Submerge completely so there will be no lines at the water line.

Have you removed the moveable jaw? If not, get it off first.

I had one lock up on me like that and if I recall correctly I ended up taking it apart and gave it a couple of sharp raps on the inside face of the shaft with a brass punch before it would break loose. I think it was a frozen up thrust bearing.

Another one for KROIL here. Soak it down good and put in a garbage bag tied shut. The volatiles won't evaporate and it will work that much better.

Interesting. So after applying you wake up and it smells like breakfast is cooking?

Another one for Kroil. I often find that adding heat to expand one part away from the other helps. After a Kroil soak, heat, more Kroil, more heat, might also consider an impact hammer cautiously applied to further loosen things. 200 ft. lbs. of impact often seems to beat 400 ft. lbs. hanging on a bar. If it won't back right out after that, maybe tighten, back out, tighten, to see if you can get it free.

Sounds like you're going to want a Kurt rebuild kit no matter what you do to get it unstuck.

I don't frequent the General board much.

I have used Kroil, good stuff for sure but I like Break Free better. The stuff is magic! McMaster Carr has it.

Hello Ox,
let us know what works best for you. My vises need a clean-up grind, The original finish was perhaps too coarse. But I think poor maintenance on my part is the main reason.
