Is it time to change the user name to Kan'tdo?:laughing:
Possibly, or maybe "Idon'tCare" as he seems to be happy pumping out the oil that he can, and just leaving the nasty, degraded, and metal flake fluid at the bottom of the pan, which will get splashed on the gears!.

FSU Alumni are better. :p My beer money is still on Kando. Im now thinking the plug is cross threaded and whoever put it in last used a cheater on the wrench to keep it from leaking.

My money is on Kando as well. He has, however, been grinding on the edges of that plug and that increases the odds that when he finally does get a wrench onto it that bites, it will or could shear off the gripping portion of the exposed part of the plug. Were that to happen the mission will shift from how to remove the rounded off drain plug to the issue of how to remove the stub of a formerly rounded off drain plug. That's a whole new set of mechanical thinking and that could go another 1500 pages. Who knows?

My repeated vote is to farm this job out to a shop or at least someone with experience. It's not a difficult task but it is if it's the first time you've done it. The first time I took my backhoe off it took me 90 minutes to get it back on. We all know the drill. The second time took me five minutes. Same for Kando. This task can go wrong pretty easy and become a bigger event. Farm it out is my free advice.

Its been a while since I read this whole thread, and I do not remember.....
Has anyone confirmed that the OP has used "righty tighty, lefty loosy?"

This is NOT a political statement Wolfy!
That was brought up and Kando confirmed.

Post 1385.
Certain i'm turning in the right direction. Same direction as the other 3 loosen. Wrong direction wasn't what broke it.

I am not arguing that a Knipex pliers are stronger than a similarly sized pipe wrench but I do believe the design and actuation of the jaws and teeth create more grip than a pipe wrench... again from my experience... no data, sorry. In fact, looking at Mc/I stress, a cheater pipe may fail the Knipex handle before a decent quality pipe wrench handle, but I don't think strength of the tool is the issue.

I will vote again for Knipex and heat. A little cheater won't hurt. Looking at the OP posted pics, I would say grip is the primary issue... let's get a better grip and add some heat.

Am I missing something here?
Steel when heated EXPANDS!
Expanding the plug size will make it come out easier?

The heat and expansion weakens the lock between the parts.

Perhaps after it cools?

Or, at least equalizes. The key is a relative movement driven by a quick temperature change applied through one of the parts. The thread bond is crushed, or relaxed, depending on which part. This disturbs the bond.

What he said ^^

Rapid Heating of one of the parts to weaken the "lock" is a standard "treatment" . Try it sometime, it is amazing the difference.

To digress a little more in abstract...the "relative movement" is at (or at least begins at) the molecular level...i.e., the higher the temperature rises the faster the molecules move...as the temperature cools the molecules slow down and depending on how fast or slowly they cool determines how the atoms line up again...in the case of steel etc. the way the atoms in a particular molecule are lined up determines how hard (temper) the steel is...
...Very hot steel (cherry +) is very soft because the molecules are moving around so fast they can't possibly be lined up...

OK back to the topic at hand....still think 1/4" of threads is enough for the jaws of a properly sized pipe wrench...plus you get the full leverage of the larger arc...(further away from the center)...

For a "don't let this happen again" thought... grease the new plug with anti-seize compound ...

Aw C’MON!! I was saving that for WHEN Kando got it out.

I do too. I still feel I could have that plug out in seconds with a pipe wrench. The OP spoke of "cinching down the pipe wrench on the flats". That is precisely the WRONG thing to do. pipe wrenches aren't adjusted down, the flexible movement of the pipe wrench is the principal of how they work.

While you guys are messing around with your pipe wrenches, i'll clamp my vise grips down and turn it out.
