Re: [MBZ] More jackstand overkill ...
Heat it with a propane torch but cut the brake hose first. Shouldn't be an issue if you are replacing the hoses anyway. If you don't cut the hose, you run the risk that it will blow off. You can guess how I know that.

I squirted the threads of the bleeder screw with Kroil and then came into the office to write this email while the Kroil does its work. We will see if that works.

Do you use anti-seize on them or is that not advisable?

While it’s more of a preventative thing, I always make sure I have the rubber caps for bleeder screws. I keep some on hand to replace missing ones. -D > On Sep 20, 2023, at 11:00 AM, Craig via Mercedes > wrote: > > On Wed, 20 Sep 2023 07:20:50 -0700 Jim Cathey via Mercedes > wrote: > >>> I squirted the threads of the bleeder screw with Kroil >> >> I would also want to get some down the throat too. >> Work from the inside against the sealing face.

Re: [MBZ] More jackstand overkill ...
Old muzzle loading guns come in 2 basic flavors, flintlock and caplock. Caplock guns use a percussion cap to ignite the powder, percussion caps are little copper or brass cups with some goop that explodes when the hammer hits it. The thing the cap sits on is a "cone" or more commonly a "nipple". They look like a squared off grease fitting and on old guns are very often stuck and some are stuck bad. One of the worst I've ever worked on was an old side by side shotgun with a muzzle that looked like it had been stored in a lake. The cones were pretty beat up and wanted replacing, I soaked them in oil for a few weeks, tapped on them, heat, oil, tap, repeat. After a couple weeks I finally resorted to vice grips and, happily, they both came out. Patience is the key when removing stuck things...

IIRC, heat also helps loosen rusted threads, though I guess the Kroil will burn off now if you hit it with a torch. Could make a mess of things. If it comes to it, if it breaks off, drill it out and use an "EZ-out" (or whatever they call those things) to get it out and replace it with a new bleeder valve. --- Original Message --- On Tuesday, September 19th, 2023 at 9:58 PM, mitch--- via Mercedes wrote: > > > Don't forget to hit the bleeder screw with a hammer as if it were a > nail. > Helps jar things loose, but just thump it once, don't beat it into > something non bleeder shaped. > > ___ > http://www.okiebenz.com > > To search list archives http://www.okiebenz.com/archive/ > > To Unsubscribe or change delivery options go to: > http://mail.okiebenz.com/mailman/listinfo/mercedes_okiebenz.com ___ http://www.okiebenz.com To search list archives http://www.okiebenz.com/archive/ To Unsubscribe or change delivery options go to: http://mail.okiebenz.com/mailman/listinfo/mercedes_okiebenz.com

Re: [MBZ] More jackstand overkill ...
Don't forget to hit the bleeder screw with a hammer as if it were a nail. Helps jar things loose, but just thump it once, don't beat it into something non bleeder shaped. ___ http://www.okiebenz.com To search list archives http://www.okiebenz.com/archive/ To Unsubscribe or change delivery options go to: http://mail.okiebenz.com/mailman/listinfo/mercedes_okiebenz.com
