Welding Thrust on Cast Crank?

[devo340]

We were going through 360 thrust bearings every 10 passes.
Like you, had a small investment in the crank.
Sent it to Ohio Crankshaft & had it repaired.
Killed it in 10 passes.
Wasn't a concern with the crank repair.
Found the convertor snout was bottoming out in the crankshaft.
The mounting lugs were .015 away from the flex plate.
Changed convertors & never had the problem again.
