 Topic: favorite thread loosenerupper
Posted: 06 Jun 2012 at 8:24pm |
 OK, I remember discussion week or two ago about penetrating stuff. I been working on two slack adjuster screws for about a week.......here and there. I got one loose tonight. Pics above of screw, on left is end with Kroil treatment, on right, heat and wax. the kroil never made it past the first half thread, the wax about 2-3 threads. In the end, I won with heat, lots of BFH, and pipe wrench with four foot cheater!
I think I'm going to take the stub in first pic, weld a flange on it, and use a rear lift cylinder from a WD, weld a flange on it, to mate to the stub and try to make a hydraulic slack adjuster, using grease. Any thoughts?
the next one to get apart.

Lou, are you worried on what's left of the paint on it? If it were me, I would make up a batch of electrolysis juice and dip it for a couple days hooked up to a battery charger. there's alot of guys that have done things that way and loosened them up by hand once they were done. Don't know if it would work on something that big but I don't see why not. Best part is it works while you're gone doing other things.

Looks like a good place for some stainless all thread. If you use a cylinder, would you tighten them with full hydraulic pressure or would you snug em up and close an inline valve ?

What paint? LOL
Actually, the one on the bottom was in a electrolysis tank for about two weeks.......I couldn't tell much difference, but I think it was under powered

I don't have a lot of good thread on either of the screws I have, so i suspect most of the slack will be taken up by pumping grease into the cylinder with a grease gun

You just pump grease into the cylinder. when you diconnect the grease gun it locks the grease in and holds it in place. when you want to retract it take the grease fitting out and compress it the grease will come back out. If I rember right we chained the yoke and track near the bull gear and backed up slightly grease sprayed out and shot everywhere. That was 35 years ago so my memory could be slightly wrong.

What ever you do, don't take the grease fitting out if there is the least bit of pressure on the front idler. The grease fitting can become a lethal projectile (bullet) with any pressure on the cylinder. That is why Cat's have release valves on the track adjuster cylinders.

Lou try the Mopar stuff. It really works and penetrates deep. Have used it on a bunch of stuff that would normally broken when taking apart.

I remember the penetrating oil post the other day where someone brought up acetone and ATF 50/50 mixture.I mixed up a quart batch today and will try it in the future to see how it works.
