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.

i use 7018 rod 3/32 diameter on almost everything.. Set about 90 amps.. You have to VEE out the crack to the bottom and weld out so there is no left over "crack" to start a second failure.. I grind all the metal to clean, no rust, no paint within 1/2 inch of the weld.. No preheat is needed if the parts are less than 1/2 inch thick, but if the metal is below 30 degrees, i preheat the area to get up above 100 degrees.
