Hi Ricky, I really appreciate your wealth of experience , with my hobby welding ( which nearly came to an end ,with a new pacemaker) ! Every bump forward with new ways and techniques, are always another "feather in my knowledge hat" , with different ways to resolve the issues on repairing the old iron ! Thanks again Ricky, for you time, devoted to this post,

Success = not giving up??? Are the final drives on Cubs Cast "iron"? or cast steel? I have welded since I was a kid (now 46) and for a few years as a job. I apparently don't know diddley about welding cast iron because 2 out of 3 times I failed. First attempt was a Ford engine block with a cracked freeze plug hole - kept chasing the crack and ended up at the oil pan before i sold it for parts. :-( Used stick welder with 95 nickle rod, preheated and peened as it cooled, even drilled a tiny hole at the end of the cracks. Second attempt was a Farmall Cub front casting, same technique and same results...It cracked again in little places. Bought a new casting. Third attempt was a final drive flange on a Farmall Cub where it bolts to the axle housing...Ground everything to a bevel leaving just enough of the break to aid in aligning all the broken pieces (lots of pieces) then clamped it to something flat. I remember keeping it clamped and welding it on one side then unclamping and welding the flat side a little at a time to prevent warping. Used my wire welder with standard wire and 75/25 gas. Ground then flat filed welds flush after the repair. SUCCESS :worthy: :{_}: After painting, you would never know it was welded and have used the tractor for years...no cracks no problems. Go figure??? Thats my experience for what it is worth. Any thoughts on my experience?

Dig a hole in the yard--build a fire in it -- heat the casting in the HOT ashes -- weld it --throw it back in the ashes and cover it with ashes then cover it with dirt for a few days to let it cool slow and even.

Stainless rod is the way to go by my limited experience.

Sounds like I need to let one of you guys repair my cracked final for a spare!
