Picked up this plow a couple of weeks ago from a package deal off the auction site. Drove 9 hours round trip to get it.
So the crank and threaded tube was rusted solid. Heat, penetrating fluid didn't matter. Way too much rust on the threads deep in the tube on the other side of the threaded portion. So after breaking the rod a couple of times I decided to drill it out and clean up the threads in the tube. I had some extra 5/8" rod from making a driveshaft for the 100, but needed a 5/8-11 die to cut the threads. Man, I don't remember what kind of steel the rod was, but it took over 3 hours of working the die by hand to cut 4-1/2" of thread on the rod.
Here's the outcome:
