I just welded my 1962 gas D-17 spindle support about a week or two ago.
The crack was discovered when I greased the support. Grease was leaking from the bottom side of the top of the support.
I degreased the area the best I could. Ground a deep chamfer into the crack.
My first pass caused the grease to heat and run out.
I then used a rose bud to heat the crack until the grease no longer was running out.
Reground the area to be welded.
Welded with 7018 (1/8") at 95 amps.
After each weld, the weld was ground down. This was done to insure there were no slag inclusions.
I just checked the weld with dye penetrant and no crack was present.
This tractor has a 500 loader and is used primarily to move large round bales.
I suspect the spindle are was cracked when the lights went out and the tractor contacted a 9" diameter post. Good thing the tractor was at idle speed.
