Breaking a Rust 'Bond'

[Tex_Cattleman]

I went to OReilly a little while ago.
Blaster - check
proper drill bit - check
threading tap - check
Threaded inserts - check
grease gun - check

I'll have a report soon enough. Great suggestions here. The green screen never disappoints!

That should break it free. Good luck!

Heat it with a torch and then some water. The quick expansion and contraction of the metal will break it free in no time.

yep

I found this and copied/pasted: Machinist Workshop magazine studied the most popular penetrating oils to see what did the best job of removing rusted bolts by measuring the pounds of torque required to loosen the bolt. I have no idea how they standardized the same rustiness in each nut/bolt they tested, but it offers some degree of a ranking, whether accurate or not.



These were the results they published:



Penetrating oil: Average load:

None...................................516 lbs.

WD-40.................................238 lbs.

PB Blaster.............................214 lbs.

Liquid Wrench........................127 lbs.

Kano Kroil..............................106 lbs.

ATF-Acetone mix......................53 lbs.



“The Auto Trans fluid- acetone mix was a "home-brew" mix of 50-50 ATF-acetone.



The home brew tested better than the commercial products in this test. Note that Liquid Wrench is about as good as "Kroil" for about 20% of the price.”

I've been in the machine shop/Forging Die business for 45 years.
This is what we use at the shop and I use at home rebuilding old cars. Inexpensive and as good or better than everything else out there.

I've heard to heat it up(not glowing hot) then touch a wax candle to it and it will wick into the parts.

Then it wouldn’t be a bad idea to drill and tap that sleeve insert grease fitting and grease away

Trey get you some Kroil Oil from Kano Laboratories and soak if down, it's a creeping oil and will even crawl up hill. If it doesn't bust loose after sitting over night I'd be surprised. I get it off Amazon.

Never heard of the ATF and Acetone mix, that is awesome. Thanks for sharing.

I was so excited about the greased hinges, I totally forgot to report on the original topic, breaking that stuck hinge loose. PB Blaster freed it up in about 10 minutes.

I work in an engine machine shop and use this trick several times a week. Exhaust bolts are a *****!
