applying force to a stuck nut or bolt
 

I am trying to find infomation about a method of losening tight nuts and bolts that incorporates the application of force over a long period of time. Theory goes like this...attach a wrench to the bolt or nut and apply some force to the wrench in the counter clockwise direction and hold that force there overnight, or for some extended period of time. Of course you would use a rope or a turnbuckle or a bungie or something. Has anyone ever heard of such a method? I swore I read it on a thread here.

Wd-40?

Heat and impact are the best IMO. I also use AeroKroil penetrating oil. You can find it on Amazon.com, or you can use PB Blaster which is easily found but doesn't work as well.

I've never heard of the method you're describing. Sounds like a very time consuming way to work.:D

Havent heard of that process before.

What type of fastener are we talking about. Similar or dissimilar metals?

Soak in penetrating oil and soak some more. And soak some more. And repeat.

I just remembered one example of what you're talking about.

I've read of using a floor jack on a cheater bar to let the weight of the car break the drain plug free on the rear diff.

There must be a reason why all garages seem to have impact wrenches in them.

I don't have any stuck bolts or nuts at the moment, and I have used Kroil for years. I'm trying to find out if such a method is valid or just some shade tree mechanic fable. Unless I imagined it, the method involves holding a moderate amount of force on a wrench (any kind of wrench), as long as overnight, to loosen the nut or bolt (any kinds of nuts or bolts). I remember thinking it was b.s. when I read it. In theory, it would create some amount of torque in the stud or nut.

i have never used it on a wrench but i have tightened a puller as tight as i dared on a mechanicle seal sleeve(trash pump water seals) and left it over night to find the puller laying on the floor with the sleeve off the shaft.

Are you sure it wasn't a recipie for bread? :D

Yeah, like that. Thanks.

If its not that big, take it to your local autozone, they just broke loose an alternator pulley bolt for me in 10 seconds after i struggled for 2 hours (hammer, blowtorch, and ice were useless...)

must get impact wrench.

Then fetch your cutoff wheel...

This sounds like a job for "Myth Busters!":D

I love that show.:D

This episode made me a little sad though:
