I have some wear in the contact area  where the direct drum contacts the drive lugs of the sun shell.  Near as I can measure, it's around .050".  I can easily dress it up to take off the worn area, question is, how much is too much wear and what problems will it cause?  I'm pretty sure I can put a little weld on the area to put it back to the stock dimension, anybody tried this?
